Answer:
x = 7
Step-by-step explanation:
We are told one quarter of x is equal to 7 , then the equation is
x = 7 ( multiply both sides by 4 to clear the fraction )
x = 28
Step-by-step explanation:
First, multiply each side of the equation by
2
to eliminate the fraction while keeping the equation balanced:
2×A=2×h2(a+b)
2A=2×h2(a+b)
2A=h(a+b)
Now, divide each side of the equation by
a
+
b
to solve for
h
while keeping the equation balanced:
2Aa+b=h(a+b)a+b
2Aa+b=h(a+b)a+b
2Aa+b=h
h=2Aa+b
Answer:
9
Step-by-step explanation:
I used tan but there's probably an easier way to do this but 4*tan(20)=8.94 then round it up to 9
Perimeter of the triangle is 30.75 inches.
Step-by-step explanation:
- Step 1: Given sides of the triangle = 11.25 in, 9.25 in, 10.25 in
- Step 2: Formula for perimeter of triangle = length of sides of the triangle
- Step 3: Substitute in the formula
Perimeter = 11.25 + 9.25 + 10.25
= 30.75 inches
