Answer:
<h2>
11.11 square yard </h2>
Step-by-step explanation:
Step one:
given data
charges=$90
installation=$9 per square yard
total cost of installation= $810
let x represents the number of square feet
Step two:
The expression for the installation cost is given as
810=9x+90------------1
solve for x, collect like terms
810-90=9x
720=9x
divide both sides by 9 we have
x=720/9
x=11.11 square yard
The rule when an exponent is raised by another exponent is:
(a^b)^c = a^(b*c)
In this case:
(4^3)^5
4^(3*5)
4^15
Answer:
i think it might be c

tell me if its wrong or not and brain list please
Answer:
The equation x = -3y + 4 6y + 2x = 8 has <u>infinite </u>number of<u> </u>solutions.
The answer is 22 because you replace the x with 5 and do 5x 5 - 3
