Answer in 3 complete sentences.
Answer:
Perform the actual multiplication problem either by hand or with a calculator. In this example, students would multiply 21 times 31 to get 651. Subtract the smaller number from the larger one to check for reasonableness. In this example, you would subtract 600 from 651 to get 51.

On Monday, Elsbeth’s bank account balance was -$16.75. On Tuesday, she deposited a check for $5.72. On Thursday, she deposited $16.75. What is her new balance?
-16.75 + (5.72 + 16.75) Use the commutative property to get:
-16.75 + (16.75 + 5.72) Use the associative property to get:
(-16.75 + 16.75) + 5.72
On Friday, Elsbeth deposited her paycheck for $872.56. What was the account’s final total?
-$866.84
$878.28
$895.03
$903.10
================================================
Explanation:
She starts off $16.75 in debt
Later on she deposits $16.75 to get completely out of debt and make the balance 0. This is after depositing the $5.72
So far her balance is $5.72
Add on $872.56 to get 5.72+872.56 = 878.28
-------------
This is what your steps may look like
-16.75 + (5.72 + 16.75)
-16.75 + (16.75 + 5.72)
(-16.75+16.75) + 5.72
(0) + 5.72
5.72
5.72+872.56
878.28
Answer:
B) $878.28

Can someone do an explanation on how to solve 15/20 - 3/20 in simplest form
Answer:
11/20
Step-by-step explanation:
Answer:
3/5
Step-by-step explanation:
Since both 15/20 and 3/20 have a common denominator you just subtract 3 from 15 and you get 12/20
Since both sides can be further divided by 4, you get 12÷4/20÷4 which equals
3/5 which cannot be further simplified
write a number that when rounded to the nearest tenth would be 0.2.
Answer:
0.15 or 0.16 or 0.17 or 0.18 or 0.19 or 0.20 or 0.21 or 0.22 or 0.23 or 0.24
(hundreds/thousandths/ten-thousandths etc place can be anything!)
Step-by-step explanation:
for a rounded number to the nearest tenth to be 0.2, then if the number's tenth place is 1 then the hundredth must be 5-9 so that it rounds up and if the number's tenth place is 2 then the hundredth must be 0-4 so that it rounds down. the tenth place can only be 1 or 2. the hundredths and above places don't matter since they don't affect the tenth place

Marcus invested $2000 in a bank account earning simple interest. The interest, I, he has after t years at an interest rate r is given by this equation.
l = 2000 rt
After 2 years, the total amount in the account was $2160. What was the annual interest rate?
Drag and drop an answer choice into each empty box below
The annual interest rate was
4%
8%
16%
40%
The value of the annual interest rate will be;
⇒ 4%
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division
Given that;
The invested amount = $2000
And , I = 2000 rt ….(i)
Now,
Since, The invested amount = $2000
⇒ Interest ‘I’ = $2160 - $2000
= $160
Time ‘t’ = 2 years
Substituting these values into;
⇒ 160 = (2000 x 2) r
⇒ r = 0.04
⇒ r = 4%
Thus, the interest r = 4%

Answer: The blue car gets 26 2/3 mpg
The silver car gets 34 mpg
The silver car can travel farther on one gallon of gas. By about 7 1/3 miles.
Step-by-step explanation:
Divide miles by amount of gas.
Blue: 35 1/2 ÷ 1 1/2 = mpg
71/2 ÷ 3/2 => 71/2 × 2/3= 71/3
Simplify 26 2/3 mpg
Silver: 27 1/5 ÷ 4/5 =>136/5 × 5/4

The relationship between the slope of AC¯¯¯¯¯ and the slope of CE¯¯¯¯¯ cannot be determined, because the triangles are congruent. The slope of AC¯¯¯¯¯ is greater than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .

A biking track has a length of 0.9 miles . How long is this in feet ?
First fill in the blank on the left side of the equation using one of the ratios. Then write your answer on the right side of the equation.
The biking track of 0.9 miles is 4752 feet long.
Length of the biking track = 0.9miles
What is the relation between mile and foot?We know that 1 mile equals 5280 feet or the length (in feet) is equal to the miles multiplied by 5,280.
The length of the biking track = 0.9miles
So, The length of the biking track(in feet) = 5280*0.9 feet
The length of the biking track(in feet) = 4752 feet.
Therefore, the biking track of 0.9 miles is 4752 feet long.
