Step-by-step explanation:
Hello There!
If you didn't know vertical angles are congruent
That being said we can use this equation to solve for x
40 = 5x
Objective: Isolate the variable using inverse operations
To get rid of the 5 we divide each side by 5
40 / 5= 8
5x/5=x
we're left with x=8
To check our answer we can plug in 8 to x and if it equal 40 then the answer is correct
5(8) = 40
So the answer would be 8
Answer:
Step-by-step explanation:
y = x/4 - 12
x = y/4 - 12
y/4 - 12 =x
y/4 = x + 12
y = 4x + 48
h(x) = 4x + 48
y = 3x - 122
x = 3y - 122
3y - 122 = x
3y = x + 122
y = x/3 + 122/3
f^-1(x) = x/3 + 122/3

Answer:
Locker B, it has 1440in² more space
Step-by-step explanation:
Locker A has an area of 7200in²
12*60*10=7200
Locker B has an area of 8640in²
48*12*15=8640
Answer:
Area of the walkway border is 736 ft²
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides and four angles) with two pairs of opposite and parallel sides. All angles in a rectangle are 90 degrees each. Also, opposite sides are equal.
The entire pool area has a length of 60 feet and width of 40 feet. The area of the entire pool area is:
Area of entire pool = length * width = 60 feet * 40 feet = 2400 ft²
The area of entire pool
A walkaway border of 4 ft is made around the pool area. There is a decrease of 4 ft round the sides of the pool area.
Therefore length of pool = length of entire pool area - 4 feet border at left - 4 feet border at right = 60 ft - 4 ft - 4 ft = 52 ft
width of pool = width of entire pool area - 4 feet border at top - 4 feet border at bottom = 40 ft - 4 ft - 4 ft = 32 ft
Therefore the pool is 52 ft × 32 ft
Area of pool = length * width = 52 ft * 32 ft = 1664 ft²
Area of the walkway border = Entire pool area - Area of pool = 2400 ft² - 1664 ft² = 736 ft²
