Answer:
y = -32
Step-by-step explanation:
-6(y+15)=-3y+6
Distribute
-6y - 90 = -3y +6
Add 6y to each side
-6y -90+6y = -3y+6y +6
-90 = 3y+6
Subtract 6 from each side
-90 -6 = 3y +6-6
-96 = 3y
Divide by 3
-96/3 = 3y/3
-32 = y
Answer:
let the width be x inches
then the length would be 3x inches
perimeter of rectangle = p = 2(l+b)
100= 2(3x+x)
100= 2(4x)
100=8x
x=100/8
x=12.5 inches
thw width is 12.5 inches and length is 3*12.5=37.5 inches
Step-by-step explanation:
The area of the rectangular is expressed in the formula A = l*w where l is the length and w is the width. from the first satement, l = 2 + w; then A = (2+w)*w = 2w + w^2. If A is equal to 168, then w should be equal to 12 feet and l is equal to 14 feet. Hence the width due to the border limits is 12- 2*2 equal to 8 feet

Explanation:
4(4x−8)+4(3x−7)=7(2x+5)+6
Step 1: Simplify both sides of the equation.
4(4x−8)+4(3x−7)=7(2x+5)+6
(4)(4x)+(4)(−8)+(4)(3x)+(4)(−7)=(7)(2x)+(7)(5)+6(Distribute)
16x+−32+12x+−28=14x+35+6
(16x+12x)+(−32+−28)=(14x)+(35+6)(Combine Like Terms)
28x+−60=14x+41
28x−60=14x+41
Step 2: Subtract 14x from both sides.
28x−60−14x=14x+41−14x
14x−60=41
Step 3: Add 60 to both sides.
14x−60+60=41+60
14x=101
Step 4: Divide both sides by 14.
