The perimeter equation for a rectangle is two times the base plus two times the height.
2B + 2H=P
Plug in the known values and solve for x.
2(2x) + 2(x+1)=53
4x+2x+2=53
6x=51
x=8.5
Now that we know what x is, put it back into the formula for the height of the rectangle to find the final answer.
H= x+1
H=8.5+1
H=9.5 ft
It would be 3 times the sum of x and seven plus 10. This is because first you would would add 7+x (7x) and multiply it by 3. And then add on 10.
Answer:
44
Step-by-step explanation:
The sum of the ratios is 6 + 2 + 3 = 11
Let b = total number of boots sold last week
If 24 football boots are sold, the equation representing this =
6/11 x b = 24
To solve for b, divide both sides by 11/6
b = 44 = total number of boots sold last week
Answer:
x = 8 and y = 5
Step-by-step explanation:
2x - 3y = 1 --(1)
x + 2y = 18
x = 18 - 2y --(2)
sub (2) into (1):
2(18 - 2y) - 3y = 1
36 - 4y - 3y = 1
-7y = 1 -36
7y = 35
y = 5
x = 18 - 2(5) = 8
