(5x+7) + (8x-21) = 90
13x-14 = 90
13x= 104
X=8
The angle measurements are 47, and 43
perimeter of the object = W+X+U+Y+Z+V+T+Y
= 140+112+88+19+110+66+84+19= 638 inches
Answer:
P = 75*
Step-by-step explanation:
Answer:
93.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 93.5
Hope this helps!!
