Answer:
x = 4
Step-by-step explanation:
4x = 16
divide both sides by 4:
⇒
⇒ x = 4
5t+5=30
divide both sides by 5
t+1=6
minus 1 both sides
t=5
Answer:
x>1
Step-by-step explanation:
m at h w ay
25, 65, and y make a right triangle. use a^2 + b^2 =c^2.
so...
y^2 + 25^2 = 65^2
y^2 + 625 = 4225
y^2 = 3600 take the square root of both sides
y=60
Answer:
114.12
Step-by-step explanation:
A = (a+b)/2 ×h
= (6.2 + 25.5)/2 ×7.2
=114.12
