The straight line equals 180
The two angels have to equal 180
180-63=117
117-25=92
92 divided by 4 is 23
x=23
I hope this helped!
Answer:
A) L = 2*W
B) 2L + 2W = 42
We'll put Equation A) into B)
2*2W + 2W = 42
4W + 2W = 42
6W = 42 cm
Width = 7 cm
Length = 14 cm
Step-by-step explanation:
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50
it is the last one im pretty sure
