Answer:
x= 6/5y+6/5
x= 2/3y+6
Step-by-step explanation:
3x-18=2y
Step 1: Add 18 to both sides.
3x−18+18=2y+18
3x=2y+18
Step 2: Divide both sides by 3.
3x/3= 2y+18/3
x= 2/3y+6
#2
5x−6y=6
Step 1: Add 6y to both sides.
5x−6y+6y=6+6y
5x=6y+6
Step 2: Divide both sides by 5.
5x/5= 6y+6/5
x= 6/5y+6/5

<h3>Answer</h3>
1/81(C)
<h3>Step-by-step solution</h3>
(3)^4=81
if 3^-1=1/3
so, 3^-4=1/81(C)
Answer:
x = 5
Step-by-step explanation:
You have a right triangle, so you can use the Pythagorean Theorem.
a^2 + b^2 = c^2
x^2 + 12^2 = 13^2
x^2 + 144 = 169
x^2 = 25
x = 5
Answer: x = 5

Step-by-step explanation:
Let p1 be the perimeter of triangle ABC
p2 be the perimeter of triangle PQR
p1=(2x+4)+(2x+3)+(2x) = 6x+7
p2=(2x)+(2x)+(3x+1) = 7x+1
p1=p2 ⇔ 6x+7=7x+1 ⇔ 7x-6x=7-1 ⇔x=6
Then :
AC=2(6)=12
AB=2(6)+4=16
BC=2(6)+3=15
PQ=12
QR=12
PR=3(6)+1=19.
