Answer:
x = 13
Step-by-step explanation:
5x + 25 must equal 7x - 1, because all of the angles in the figure are right angles.
Then 5x + 25 = 7x - 1, and
25 = 2x - 1, and so 2x = 26 and x = 13
No because if you plug in 4 for x and 5 for y you get -4 not 36
Answer:
Option H
Step-by-step explanation:
Perimeter of rectangle= 2(length) +2(width)
100= 2(5a -22) +2[½(a +1)]
Expand:
100= 2(5a) +2(-22) +a +1
100= 10a -44 +a +1
Simplify:
100= 11a -43
+43 on both sides:
11a= 100 +43
11a= 143
Divide both sides by 11:
a= 143 ÷11
a= 13
Thus, option H is correct.
