(1 2/5)(x)=7
Simplify both sides of the equation.
7/5x=7
Multiply both sides by 5/7.
(5/7)*(7/5x)=(5/7)*(7)
x=5
Answer:
a = 4
Step-by-step explanation:
a^2 + b^2 = c^2
a= ?
b= 3
c= 5 (c is always the hypotenuse)
*plug in given values
a^2 + 3^2 = 5^2
a^2 + 9 = 25
-9 -9
a^2 = 16
*find the square root
sqrt(a) = sqrt(16)
a = 4
160 inches... I am 98% sure I am correct
Answer:
sln
3b-2a=7
3b-7=2a(divide by 2 both sides)
a=3b-7/2
