Thanks!
<span>m = j + 16
m + 5 = 3j
---
put the system of linear equations into standard form
---
m - j = 16
m - 3j = -5
---
x - y = 16
x - 3y = -5
so now that you have your equations formed, just solve.
x - y = 16 , which means that x = y + 16
substitute for x in the second equation :
Hope this helps

Step-by-step explanation:
add the perimeter of the first triangle to get 65
then divide 65 by 26 to get 2.5
then divide all the side lengths by 2.5
15/2.5=6
20/2.5=8
30/2.5=12
Astt: Angle Sum Tri Theorem
Answer:
C. 28 ft³
Step-by-step explanation:
The general formula for the volume of a pyramid:
V = 
, where B = the area of the base and h = height of the pyramid
Since the base is a rectangle, we can find area using the formula:
A = l x w or A = 3 x 4 = 12 ft²
Using B = 12 and h = 7:
V = 
V = 28 ft³
