Answer:
9
Step-by-step explanation:
If S is between R and T, then RS+ST = RT
Given the following parameters
RS=2z+6,
ST=4z−3,
RT=5z+12
On substituting
2z+6+4z-3 = 5z+12
Collect like terms
2z+4z-5z = 12+3-6
6z-5z = 15-6
z = 9
Hence the value of z is 9
Answer:
LINE D
Step-by-step explanation:
Divide 4 by 1/10.
So, 4 ÷ 1/10 becomes 4 x 10/1.
We know that 4 x 10/1 = 40/1 = 40.

Answer:
150
Step-by-step explanation:
To solve the problem, put 5 instead of x, so 5*3
and put 10 instead of y, so 10*1
when combined,
(5*3) * (10*1)
= 15 * 10
= 150
Hope this helps!!

Answer:
L = 25
Step-by-step explanation:
Let's call the Length x and width x - 15 since the width is 15 less than length
Eric needs 70 of fencing in total, the perimeter of a rectangle is calculated by adding all sides
x + x + (x - 15) + (x - 15) = 70 add like terms
4x - 30 = 70 add 30 to both sides
4x = 100 divide both sides by 4
x = 25
