We need to isolate z on one side of the equation.
First, add 3/7 to both sides of the equation (this will cancel out the -3/7):
2z < 49 + 3/7
Let's change (49+3/7) into an improper fraction:
2z < 346/7
Divide both sides by 2 to get the answer:
z < 173/7
Answer:
780
Step-by-step explanation:
Let x be the original price
x - x*72% is the new price
x - .72x = 218.40
.28x = 218.40
Divide each side by .28
.28x/.28 = 218.40/.28
x =780
Answer:
h=A/(b1+b2/2)
Step-by-step explanation:
it is the reverse
The diameter of the plate is 12, and the formula for finding circumference is diameter times pie. so you multiply pie (or 3.14 if you aren't using a calculator) times 12 and it should give you 37.6991. rounded to the nearest tenth, that's 37.7, hope I helped!
1 - (1/4 + 2*1/4)
1 - 3/4
1/4 of the living room still remains unpainted.
