2ˣ = 2³
Since 2ˣ is EQUAL to 2³ and since 2 is equal to 2, then the solution is a must that the 2 exponents are equal.
Then x = 3
Answer:
-43
Step-by-step explanation:
first we need to do 9x witch would be 9x3 so 9x3 is 27 now its down to -16 - 27 and that is -43
For Ramona to know how much she expects to pay for the carpet she is ordering, she first needs to know how many square foot the the room has.
In getting the area of the room, you multiply one side with the other,
in equation,
19.5 ft x 41.6 ft = 811.2 sq ft.
Then if the carpet costs $9.50 per sq ft, you simply multiply it the area of the room
in equation,
$9.50/ sq ft. x 811.2 sq ft, cancelling out the unit of sq ft
the answer would be $7,706.4
Answer:
l = A / w
Step-by-step explanation:
Given:
A = lw
Where,
A = area
l = length
w = width
write a formula for the length
A = lw
Divide both sides by w
A / w = lw / w
A / w = l
It can also be written as
l = A / w
That is, length = Area / width
However, no baking sheet is shown
The formula to find the length of the baking sheet = Area / width
5/8x + 1/5x can be written with a common denominator:
25/40x+ 8/40x = 99
This can be simplified to:
33/40x = 99
Next times both sides by 40
33x = 3960
Then, divide both sides by 33
x = 3960/33
x = 120
