Answer:
Step-by-step explanation:
First add the shoes and the toys: 63+54 = $117
Second subtract 45 dollars from $117 = 72
Third divide 72 by 9 = 8 weeks
Answer: 8 weeks
Answer:
The price of the shirt is $7.50
The price of the pants is $18.50
Step-by-step explanation:
If you want to write something for your proof of work:
4x + 3x = 85.50
3 (4x + 3y ) = 3 (85.50)
12x + 9y = 256.50
12 × 7.50 = 90
9 × 18.50 = 166.50
ALSO for the last question:
12 × 7.50 = 90
20 × 18.50 = 370
370 + 90 = $460.00
Answer:
x = -1
y = 0
Step-by-step explanation:
to solve the equation by substitution in order to evaluate for x and y
let
6x-2y=-6 ................................................ equation 1
-2x-3y=2 .................................................. equation2
from equation 2
-2x-3y=2 .................................................. equation2
-2x -2 = 3y
divide both sides by 3
(-2x -2)/3 = y
y = (-2x -2)/3 ................................... equation3
substitute y = (-2x -2)/3 into equation 1
6x-2y=-6 ................................................ equation 1
6x - 2[ (-2x -2)/3] = -6
6x + (4x + 4)/ 3 = -6
multiply through by 3
18x + 4x + 4 = -18
22x = -18-4
22x = -22
divide both sides by the coefficient of x which is 22
22x/22 = -22/22
x = -1
substitute for x in equation 3
y = (-2x -2)/3 ................................... equation3
y = -2(-1) - 2/3
y = 2 -2/3
y = 0/3
y = 0
therefore the value of x and y is -1 and 0 respectively
A=24
Find the area by multiplying both diagonals and dividing them by 2. Like so: And you might be wondering how to do that. By using the pythagorean theorem and some simple addition, you could get the answer. One diagonal is 8 and the other is 6....so, 8x6=48....48/2=24

Answer: 300 cubic inches
Explanation:
Imagine slicing the T shape into two pieces such that we have two rectangular blocks.
- The larger block down below has volume of 3*12*5 = 180 cubic inches.
- The smaller block on top has volume of 8*3*5 = 120 cubic inches
The overall volume of this T shape is 180+120 = 300 cubic inches.
