Answer:
r ≥ 6
Step-by-step explanation:
37+15r ≥ 127
-37 -37 37 cancels and you're left with 15r
15r ≥ 90
/ 15 /15 15 cancels and you're left with r
r ≥ 6
Answer:
The volume of the larger rectangular prism is 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x-----> the volume of the larger rectangular prism
y-----> the volume of the smaller rectangular prism

In this problem we have
---> the scale factor is equal to the ratio of its corresponding sides

substitute and solve for x


Answer: x = 24
Step-by-step explanation:
9x - 18 = 7x + 30
9x - 7x = 30 + 18
2x = 48
x = 48/2 = 24


y = quantity, for example:
I want to buy 1 bracelet =
1×7 = 7 + 1 = 8$ per bracelet
