Option #1 (and the fastest):
Multiply both sides by 3 to cancel the “divided by 3” on the left side where z is.
z/3 • 3 = 5/4 •3
z = 15/4
Option #2: Cross multiply and then solve for z:
z/3 = 5/4 -> 4z=15
Then divide by 4.
4z/4 = 15/4
z = 15/4
Answer:
a=326.76 yd^2
Step-by-step explanation:
a= 2pi(d/2)h+2pi(d/2)^2=2pi(8/2)9+2pi(8/2)^2= 326.72564yd^2
Answer:
a = 5
Step-by-step explanation:
a +a+4 + 2a-3 = 21
4a +1 =21
4a = 20
a = 5
