Answer:
x=18
Step-by-step explanation:
y=3x-4
3x-4=y
3x-4=50
3x=50+4
3x=54
x=54÷3
x=18
Answer:
C. C = 3P
Step-by-step explanation:
C = total costs
P = number of popsicles
Unit price of 1 popsicle = $3
To get the total cost of popsicles, we need to multiply the number of popsicles bought by the price of each popsicles
Total cost of popsicles = number of popsicles × unit price
Thus, the question would be written as:
C = 3P
Square:
We know all sides of a squares are equal in length.
s= the length of one side of the square.
45= s+s+s
45= 3s
s=15 inches
Each side of the square is 15 inches.
Rectangle:
length(l)= ????
Width(w)= s = 15 inches
l -w= 5inches
l- (15 inches)= 5 inches
l = 20 inches
Answer:
A length of the rectangle is 20 inches long.
Answer:
8.4
Step-by-step explanation:
The diagonals of a rectangle are equal.
That means WY = XZ
16x+2 = 36x-6
Subtract 16x from each side.
16x -16x+2 = 36x-16x-6
2 = 20x -6
Add 6 to each side
2+6 = 20x-6+6
8 = 20x
Divide by 20
8/20 = 20x/20
2/5 =x
We want to find the length of the diagonal
WY = 16 ( 2/5) +2
Changing to decimal form
WY =16 * .4 +2
WY =6.4+2
= 8.4
-x(-x+8)
