Ralph bought 3 boxes with 20 pencils each and 4 boxes with 10 pens each. To find the total number of pencils and pens, Ralph evaluated 3 X 20 + 4 X 10 = 100. Is his answer reasonable? Explain.
Answer:
yes, his answer is reasonable because three times twenty is sixty, and four times ten is forty. sixty plus forty is 100.
Step-by-step explanation:
3x20=60
4x10=40
40+60=100

Rational Numbers-
1. -2 4/5 - 6 2/15
2. -5/12 + 7/8
3. 3 3/5 x 2/9
4. Convert to a decimal. -5 1/20
5. Which number is the largest? -0.65, -0.622, -5/8
Answer:
1.
-9 11/15
2. 11/24
3.
34/45
4. -5.05
5. -0.622
Step-by-step explanation:
1. -2 4/5 - 6 2/15
convert them to a common denominator and an improper fraction:
-2 4/5= 18/5=- 54/15 -6 2/15= 92/ 15
*15 is the other denominator, so you keep the numbers in the second number the same*
subtract: -54/15- 92/15
since you are subtracting a negative number it goes farther away from zero
-146/15 or -9 11/15
2. -5/12 + 7/8
convert them to a common denominator
-5/12=- 20/48 7/8= 35/40
add: -20/48+35/40
11/24
since you are adding a negative number it goes closer to zero or past zero:
3. 3 3/5 x 2/9
convert 3 3/5 to an improper fraction: 18/5
mulitply the two denominators and the two numerators
17/5 x 2/9= 34/45
This is also the simplest form.
4. Convert to a decimal. -5 1/20
keep the -5 beacuse that is a whole number
divide 1/20 to turn it to a decimal to get 0.05
5. Which number is the largest? -0.65, -0.622, -5/8
to find this you would have to convert all numbers to either a decimal or a fraction.
5/8 is 0.625
the one closest to zero is the largest which is -0.622
Hudson was comparing the price of orange juice at two stores. The equation y=0.57xy=0.57x represents what Hudson would pay in dollars and cents, yy, for xx bottles of orange juice at store A. Hudson can buy 17 bottles of orange juice at Store B for a total cost of $13.26.
Answer: x is the amount of orange juice they can buy. And y is the amount of money they have. Set y equal to 13.26 and solve the equation.

Answer:
Make sure that everything is the same format, and then add numbers.
Step-by-step explanation:
1. Covert 3/4 into a decimal.
2. Draw a line.
3. Add numbers to it.
4. Mark up the points that were given.
Answer:
The first thing that we will need to do is to convert 3/4 into a fraction which would give us 0.75 and now we can continue. We then draw a line that starts with zero and we can increment by 0.25 until we reach around 2. We then label each of the increments and plot our points and make sure that they are correct.
Dan's Deli makes a club sandwhich every 6 minutes and roast beef sandwhich every 14 minutes. If both sandwhiches were just made, how many minutes will pass before they make then both again at the same time?
Answer:
In 42 minutes
Step-by-step explanation:
Multiples of 14: 14, 28, 42, 56, 70, 84
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54
We have to find the LCM.
The LCM is 42. So it takes 42 minutes to be made at the same time again.

Answer:
1.6296*[tex]10^8[/tex]
Step-by-step explanation:
To do this problem, factoring skills are helpful
Step 1: See if both the terms (numbers) have a common factor. In this case, it's both [tex]10^7[/tex], so we can rewrite the equation as this (below) by pulling out the common factor.
(10^7)(9.54+6.756)
Solve the inside of the paranthasis to get
16.296*10^7
We're not done yet, as scientific notation requires the number in front to be from 1-9.999...
factor out a 10 from 16.296 to get 10*(1.6296)
replace the 16.296 with (1.6296)*10 to get:
1.6296*10*10^7, and combine 10*10^7 to get 10^8
final answer: 1.6296*10^8
side note: 10^7 = [tex]10^7[/tex], the upside down V indicates exponents, and 10=10^1

rule 1: 2n+1/3
from 1 the fifth is:2*5+1/3=10 1/3
rule 2:(n+1/2) *4
from 0 the fifth is:(4+1/2) *4 =18
the answer is (10 1/3, 18)

In a complete sentence, describe the relevant angle relationships in the following diagram. Find the measurement of ∠QPR.
Answer:
13
Step-by-step explanation:
First, we need to find out what 180 - 154 is because a straight line has a 180-degree angle.
180 - 154 = 26
Next, we need to divide 26 by 2 to get the angle of both sides.
26 / 2 = 13.

A pair of jeans originally cost $85 but are on sale for 45% off. What is the sale price?
Answer:
$ 46.75
Step-by-step explanation:
45% OFF means you pay 55% of original price
.55 * 85 =

Simplify the following proper fraction by reducing it to lowest terms.
8/12
A.2/3
B.3/4
C.4/5
Answer:
A. 2/3
Step-by-step explanation:
Simplify it by four, 8 / 4 = 2, 12 / 4 = 3
Answer:
A 2/3
Step-by-step explanation:
You can simplify a fraction if the numerator (top number) and denominator (bottom number) can both be divided by the same number.
So 8 and 12 are both divisible by 4
8/4=2
12/4=3
so the answer would be 2/3
