Answer:
a) identity property of multiplication
b) commutative property in addition
Answer:
1. $66
2. 30 + 4r
Step-by-step explanation:
Let
Price of admission into the park=$30
Price of every ride in the park=$4
Number of rides =x
Total cost of going to the park= 30+4x
1. How much money would Claire have to pay in total if she goes on 9 rides
Total cost of going to the park= 30+4x
When x=9
=30+4x
= 30 + 4(9)
=30 + 36
=$66
2. How much would she have to pay if she goes on r rides?
When x=r
Total cost of going to the park= 30+4x
= 30 + 4(r)
=30 + 4r
You should write a ( real world situation ) question that can only have whole numbers as a solution because you would divide and then you can not have a fraction left over so instead you add one. For instance there are 132 students going on a field trip. 20 students can fit on each bus. how many buses are needed? 7 because when you divide 132 by 20 you get 6 remainder 12. You can not just make 12 students walk to the location so you would add an extra bus.
ANSWER:
square root of ( 100x^2 + 60x + 9 )
An expression to represent the length of each side of the rug is:
square root of ( 100x^2 + 60x + 9 )
STEP-BY-STEP EXPLANATION:
Let's establish that the area of a square is the length of one of its sides squared.
Area of square = Side^2
THEREFORE:
To find the length of each side of the square, we will make side the subject in the formula as displayed below.
Area of square = Side^2
Side^2 = Area of square
Side = square root of ( area of square )
From this, we will substitute the given expression for the area of the square rug to obtain the expression for the length of each side of the rug.
Side = square root of ( 100x^2 + 60x + 9 )
