The perimeter of a rectangle is 64 inches. Find the value of x if the width is 22 inches and tenth is 2x inches.
Answer:
5
Step-by-step explanation:
Did you mean length instead of tenth? If so, 22*2=44, 64-44=20, 20/2=10. The length of the rectangle is 10 so to find the value of x, divide 10 by 2 so, 10/2=5, and x is equal to 5. : )

help with this !!! thanks
Answer: Casey bought 4 1/2 pounds of apples
The equation is 0.88x - $1.50 = 2.46
x is the unknown number of pounds of apples.
0.88 is the cost per pound, 0.88x is the total cost of the apples before the discount .The discount is $1.50 $2.46 is the cost after the discount.
Part b Step-by-step explanation:
0.88x - $1.50 = 2.46 . Add $1.50 to both sides
0.88x - $1.50 + $1.50 = 2.46 + 1.50
On left, 1.50-1.50=0 so "cancels' on the right, add $2.46 + 1.50 = 3.96
0.88x = 3.96 is the cost before discount . Divide both sides by .88
.88x/.88 = 3.96/.88 . .88/.88 = 1 so 1 'cancels' leaving x. 3.96/.88 = 4.5
x = 4.5
part c
4.5 is 4 1/2, the (previously unknown) number of pounds of apples.
Casey bought 4 1/2 pounds of apples.

Byron’s workout starts with a
warmup at home, and then he runs
at 4 mi/h. After half an hour of
running, he is 2 miles from home.
What is an equation in point-slope form that represents Byron’s
distance from home, y, after
x hours?
Answer:
An equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
Step-by-step explanation:
Speed of Byron = 4 miles / hour
Distance traveled in x hours = [tex]Speed \times time[/tex]
Distance traveled in x hours = 4x
We are given that After half an hour of running, he is 2 miles from home
So, Total distance = 4x+2
So, y = 4x+2
Hence an equation in point-slope form that represents Byron’s distance from home, y, after x hours is y=4x+2
