Answer:
-8
Step-by-step explanation:
Using PEDMAS( parentheses,exponents, division, multiply, addition, subtraction) to solve the Problem
-2(-3 + 5) - 4
First add (-3+5) because they are in parentheses.
-2(-3 + 5) - 4
=-2*2-4
Next, multiply -2*2.
-4-4
subtract -4-4
-8
-2(-3 + 5) - 4 is equal to -8
Answer:
See below.
Step-by-step explanation:
a)
2 children
$6/hour / 2 children = $3/hour per child
3 children
$8/hour / 3 children = $2 2/3 /hour per child
Her rate is not proportional to the number of children since it is $3/child for 2 children and $2 2/3 / child for 3 children.
b)
Since for 2 children she charges $3/hour per child, for 5 children multiply the rate by 5.
5 * 3 = 15
The proportional rate for 5 children is $15/hour
c)
I use the hourly rate for 1 child I calculated in part a) and multiplied by 5 to account for the 5 children.
Answer:
Each algebra book costs $60.
Step-by-step explanation:
A=bill for algebra books; S=bill for science books=A+$360
S+A=$3960 Substitute for S
A+$360+A=$3960 Subtract $360 from each side.
2A=$3600 Divide each side by 2.
A=$1800 The order for 30 algebra books cost $1800.
Individual book=A/30
individual book=$1800/30=$60 ANSWER: Each algebra book cost $60.
