Answer:
X=5.7
Step-by-step explanation:
5x-3-2x/7=24
We simplify the equation to the form, which is simple to understand
5x-3-2x/7=24
Simplifying:
5x-3-0.285714285714x=24
We move all terms containing x to the left and all other terms to the right.
+5x-0.285714285714x=+24+3
We simplify left and right side of the equation.
+4.71428571429x=+27
We divide both sides of the equation by 4.71428571429 to get x.
x=5.72727272727
4t=r
a=pir^2
sub 4t for r
a=pi(4t)^2
a=pi16t^2
a(t)=16pi(t^2)
A. a(t)=16pi(t^2)
B. sub 4 for t
a(4)=16pi4^2
a(4)=16pi16
a(4)=16*16*3.14
a(4)=803.84 square units
A. a(t)=16pi(t^2)
B. 803.84 square units
I believe the answer is -33
