<u><em>Answer: y=27 and 27=y *The answer should be positive sign.*</em></u>
Step-by-step explanation:
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
a*c=b*c
division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
a/c=b/c for c≠0
multiply by 3 both sides of an equation.
3*2/3y=18*3
simplify.
18*3=54
2y=54
divide by 2 both sides of an equation.
2y/2=54/2
simplify by equation.
54/2=27
27*2=54
54/27=2
2*27=54
y=27
Hope this helps!
Thanks!
Have a great day!
Answer:
Halving the diameter will halve the radius, so the volume of the new cylinder would be . The new volume is one - fourth of the original cylinder. So you can see the volume is now a quarter than the original one.
Step-by-step explanation:
its A f(x) =8x+6
Put the value of x in each f(x)
for instance: put the -½ in third f(x) you will have f(x)= -2,but the first f(x) =2
Convert the expression
then, multiply the fractions, numerators and denominators separately
and you'll get 10/3, to simplify it'll be 3 1/3 or 3.3333
Answer:
The percent is 75%
The amount is 45
The base is 60
Step-by-step explanation:
1) Set up the equation:
60x=45
2) Divide both sides by 60:
x=45/60
3) Simplify the fraction:
x=0.75
4) Write the decimal as a percent:
75%
