Answer:

y = 5

Step-by-step explanation:

Subtract 2y from either side. It'll cancel out both of them. Then the equation is 8y = 40.

Divide both sides by 8 and you get y=5

Pretty sure that's right. I have a dad who has a math degree so I think it would be right because he helps me every time.

Step-by-step explanation:

As shown first you combine like terms then you subtract 2y from both sides to get 40 by it self then you divide 8 by 40 to get y by itself hope this helps this answer is 100% correct and i was glad to help please give brainliest!

$8y+2y=2y+40\\10y=2y+40\\ -2y -2y\\8y=40\\y=5$

PLEASe help 30POINTS What is the length of segment AB ?

lesya692 [45]

Answer:

$\sqrt{74}$

Step-by-step explanation:

Distance between two points

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\textsf{let}\:(x_1,y_1)=(2,-6)$

$\textsf{let}\:(x_2,y_2)=(7,1)$

$d=\textsf{length of segment AB}$

Substituting points into the distance formula and solving for d:

$\implies d=\sqrt{(7-2)^2+(1-(-6))^2}$

$\implies d=\sqrt{5^2+7^2}$

$\implies d=\sqrt{25+49}$

$\implies d=\sqrt{74}$

a plastering contractor charges $18 per square yard( that is $2 per square foot). what is the cost of plastering 100 feet of wal

Tomtit [17]

Basically, this problem is going to require you to solve for the area and multiply it with the given cost unit.

Area = Length*Height
Area = 100 ft * 8 ft = 800 ft²

Total Cost = (Unit Cost)(Area)
Total Cost = ($2/ft²)(800 ft²)
Total Cost = $1,600
