What is the solution to the equation shown below?
-1/3(6x+6)+21=3y
2 answers:
Answer:
A or 19/5
Step-by-step explanation:
To solve first we isolate are variables so we distubte to get -2y-2+21=3y then we add 2y to the opposite side to get -2+21=5y. Then we add -2+21 to get 19 so are equation is 19=5y. Next we just divide 19 by 5 to get y=(19/5) or option A
-1/3(6y + 6)=3y-21 -6/3y - 6/3 = 3y-21 ( distribution) -18y-18 = 3y - 21 ———. ——— 9. 1 -18y-18 = 27y - 189 ( cross product ) -18y - 27y= -189+18 (collecting like terms) -45y = -171 ——. ——- ( dividing both sides by 45 ) -45. -45. y = 19 —- 5

Answer:
no
Step-by-step explanation:
Using substitution, subs in the points given
(15) = 5(4) - 2
15 = 20 - 2
Because the 2 sides are NOT equal the line would not pass through the point

Answer: 38.97 10% of 40 is 4 40-4=36 8.25% of 36 is 2.97 36+2.97= 38.97
The only way the expression can be factored is if a -3 is pulled out... -3(5t+2)
Answer:
yards of carpet you need: 4*10/3=40/3=13.3333 yd^2
Step-by-step explanation:
convert feet to yard:
1 yard=3 feet so
12 feet=4 yards
10 feet=10/3 yard=3.33333 yard
yards of carpet you need: 4*10/3=40/3=13.3333 yd^2
