Addition Sign RulesHere it is important to remember the rules for the addition of integers numbers:
+ + Add Final result (+) - Final result (+)
- - Add Final result (-) - Final result (-)
+ - Subtract - Final result (the sign of the integer having a greater value)
- + Subtract - Final result (the sign of the integer having a greater value)
Multiplication Sign RulesThe rules for multiplication of numbers are:
+ + or - -
The result presents a positive sign (+) because the signs are the same.
+ - or - +
The result presents a negative sign (-) because the signs are different.
For solving this question, you should apply the rules presented previously. And after that check, if your result is the same that the question gives.

Answer:27
Step-by-step explanation:
3x 11 is 33 and 3 x 5 is 15 then you would do 1 x 2 which is 2 then you would add 2 to 33 which is 35 then subtract 15 which is 20 then add 7 to get 27
Answer:
27
Step-by-step explanation:
First, you do what is inside the parantheses, so 11 - 5 is 6, then you multiply 1 x 2 = 2, and 3 x 6 is 18. Lastly, you add it all up and get the sum of 27. Hope this helps!
in a 3 digit number, the hundreds digit is four more than the units digit, and the tens digit is 3 less than the sum of the other two digits.if the sum of all three digits in the number is 17, find the three digits, than the number.
Answer: The number is 480.
Step-by-step explanation:
The question states that in a 3 digit number, the hundreds digit is 4 more than the units digit and the tens digit is twice the hundreds digit.
Answer:
480
Step-by-step explanation:
What is the sum of 4 1/12 + (-5 1/3)?
4 1/12 + (-5 1/3)=
-1 1/4Eliminate the negative and change the operation.
=4 1/12 − 5 1/3
Rewrite your equation with the parts separated.
=4 + 1 1/2 − 5 − 1/3
Solve the whole numbers.
4−5= −1
Solve the fractions.
1 1/2 − 1/3=?
Find the LCD of 1/12 and 1/3 and rewrite to solve the equivalent fractions. (Least Common Denominator)
LCD = 12

Reduce the fraction, 3/12.
−3 1/2 = −1/4
Combine the whole and fraction.
−1 − 1/4= −1 and 1/4

When working with interest, how many decimal places should you have when working with money?
2 decimal places because we're working with money
No decimal places; always round to the nearest dollar.
1 decimal place
Answer:
I'm pretty sure it's 4 decimal places but that's not one of your answers so I don't know.
Step-by-step explanation:
9514 1404 393
Answer:
more significant figures than in the answer
interest is reported to 2 decimal places when working with money
Step-by-step explanation:
Sums of money can involve large numbers of significant figures. A billion dollars, accurate to the penny, has 12 significant digits. Everyday finance may not involve billions of dollars, but measures of world economic activity may involve substantially more.
In general, if you want interest rate calculations accurate to the penny, the number of significant digits in the interest rate used must match or exceed the number of significant digits in the end result of the computation.
A million-dollar loan may have payments in the $10,000 range or higher, requiring 7 or 8 significant digits to express the payment value. Hence its computation should be made using interest rates accurate to 7 or 8 significant figures.
__
Example:
$1,800,000 loan for 15 years at 3.2% interest. The monthly payment is given by ...
A = P(r/12)/(1 -(1 +r/12)^(-12t)) . . . for principal P at rate r for t years
The payment is expected to be in the $10,000 range, so will have 7 significant figures. If we round the monthly interest rate to 7 decimal places, we get ...
A = 1.8×10^6(0.0026667)/(1 -(1.0026667^-180)) = 12,604.38
If we round the monthly interest rate to 8 significant figures, we get ...
A = 1.8×10^6(0.0026666667)/(1 -(1.0026666667^-180)) = 12,604.34
Notice there is a difference in the last digit of the payment value. We should also note here that there was no rounding at any point in the calculation until the final answer.
__
Money amounts are generally rounded to the nearest penny when reported on statements of account. That is, interest amounts are rounded, and the account value is maintained to two decimal places. Because of this, payment-by-payment loan amortization schedules may differ from the calculated values arrived at using formulas such as the one above.
For tax purposes, the amount of tax due may be maintained to a number of decimal digits greater than those that appear on the pay stub. A pay-period tax due of 5.3333, for example, may be charged as 5.33 for two pay periods and 5.34 for the third pay period. The idea is to make the yearly total come out right. Usually, 4 or 5 decimal places will be sufficient for this purpose.
_____
The short answer is ...
enough significant digits to ensure appropriate accuracy of the computed result
(for penny-accurate computations in the trillion-dollar range, 18 significant digits or more may be required.)
interest will be reported to 2 decimal places when working with money

Evaluate: -12x + 2y when x = -2 and y = -1
Evaluate: 10 + a - b when a = -4 and b = -6
Evaluate: -8(n-3) when n = -7
Evaluate: 3 - x + 2(-x + 4) when x = 9
Evaluate: 12 - (15 + y) ÷ 6 - 8 when y = -3
Evaluate: 15 - a(-b) when a = 5 and b = -5
Answer:
1) 22
2)12
3)-80
4)-16
5)-10.5
6)-10
Step-by-step explanation:
-12x + 2y when x = -2 and y = -1
= -12 (-2) + 2 (-1)
= 24 + (-2)
= 22
10 + a - b when a = -4 and b = -6
= 10 + (-4) - (-6)
= 10 - 4 + 6
= 10 + 2
= 12
8(n-3) when n = -7
= 8 (- 7 - 3)
= - 56 - 24
= - 80
3 - x + 2(-x + 4) when x = 9
= 3 - 9 + 2 (- 9 + 4)
= - 6 - 18 + 8
= - 24 + 8
= - 16
12 - (15 + y) / 6 - 8 when y = -3
= 12 - 15 + 3 / 6 - 8
= 12 - 15 + 0.5 - 8
= - 3 - 7.5
= - 10.5
15 - a(-b) when a = 5 and b = -5
= 15 - 5 (5)
= 15 - 25
= - 10

Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board. Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area. Adam says he knows another way. Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board. 1. What is the area of the board shown on the scale drawing? Explain how you found the area. Write your answer in the space below. 2. How can Adam use the scale factor to find the area of the actual electronics board? Remember, he uses a different method than Jason. Write your answer in the space below. 3. What is the area of the actual electronics board? Write your answer in the space below.
Answer:
1. Area is 1800 cm. I found this out by multiplying 36 and 50 together.
2. He can figure out that the scale factor 5:1 means that 1 cm in the drawing is 0.2 cm in reality, so he would take 36 and 50 and multiply them both by 0.2 cm then add them to get 17.2, which is the actual area of the rectangle.
3. Actual area is 17.2

Fred jumped into a lake from a rock 7 feet above the surface of the water. He sank five feet into the water and continued to swim down two additional feet.
•Sophie stated that the total distance would be 0 because the heights were additive inverses of each other.
•Jake disagrees and thinks that Fred covered 14 feet. He found his answer using a number line.
Do you agree with Sophie or Jake?
Answer:
Sophie
Step-by-step explanation:
Jake is wrong because when he jump he was out of the water and you're supposed to count what he swam in the water so Sophie is correct.

answer 32.395 pounds so 14.5 quarrs is 32.395 pounds
The approximate weight of 15.5 quarts of water will be 32.395 pounds.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a quart of water weighs about 2.09 pounds. The weight of the 15.5 quarts of water will be:-
1 quart = 2.09 pounds
15.5 quarts = 15.5 x2.09
15.5 quarts = 39.395 pounds
