Answer:
x = 4
Step-by-step explanation:
The given equation is as follows :
4(3x - 6) = 24
If we want to solve the above equation, the steps are:
Using distributive property first as:
4(3x)-4(6)=24
12x-24=24
Adding 24 both sides,
12x-24+24=24+24
12x=48
x=4
So, the value of x = 4. All given steps are correct.
Answer: length = 13
Width = 22
Step-by-step explanation:
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length × width)
The length of the rectangle is represented by (x+3) and the width is represented by (3x-8). If the perimeter of a rectangle is 70, it means that
2[(3x - 8) + (x + 3)] = 70
Dividing both sides of the equation by 2, it becomes
3x - 8 + x + 3 = 35
3x + x - 8 + 3 = 35
4x - 5 = 35
4x = 35 + 5 = 40
x = 40/4
x = 10
Length = x + 3 = 10 + 3
Length = 13
Width = 3x - 8 = 3 × 10 - 8
Width = 22
500 - 125 = 375
72.50 × 6 = 435
435 - 375 = 60.
Divide the part (60) by the whole (500) then multiply by 100 to get the percent.
60 / 500 = .12
.12 × 100 = 12%
The correct answer is B
Answer:
10.39 dollars.
Step-by-step explanation:
14 times 0.7 equals 9.8 dollars. Then, multiply 9.8 with 1.06 and you get 10.388 or 10.39 Hope this helps!
4(2+3x)= 4(2+12) = 4× 14= 56
8+12x =8+12×4=8+48= 56
Yeah, it's equal! Have a great day!
