Answer:
54 :/
Step-by-step explanation:
Well if mary ate 9 raisins and Mimi ate 6 times as much you just have to do:
9 x 6 = 54
y = 9 x 6?
Answer:
Perimeter A = 122.5
Step-by-step explanation:
Set up the following proportion
The Perimeter of B = 12 + 9 + 9 + 5
The Perimeter of B = 35
7/2 = x/PerimeterB
7/2 = x / 35 Cross multiply
7*35 = 2x Combine the left side
245 = 2x Divide by 2
245/2 = 2x/2 Do the division
122.5 = x
The Perimeter of A = 122.5
Problem 3
If you compare the sides opposite the angle marked with a single arc, you will get the scale factor.
If these triangles are similar, and one of the sides opposite their markings will give you the scale factor
18/7.2 = x/1 where x is the scale factor going from the larger to the smaller triangle.
2.5 = x
So if you multiply the smaller triangle's sides by 2.5 you get the larger triangle.
The expression for the product of y and 9 is 9y.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The product of y and 9.
This can be written as,
= 9y
Thus,
The expression is 9y.
