Answer:

r = -39

Step-by-step explanation:

So we are trying to solve the equation for r.

-6(2r + 8) = -10(r - 3)

Divide both sides by -2. (This will make distributing much easier.)

3(2r + 8) = 5(r - 3)

Distribute the 3 on the left side and the 5 on the right side,

6r + 24 = 5r - 15

Subtract 24 from both sides.

6r = 5r - 39

Subtract 5r from both sides.

r = -39

So now we have solve the equation.

I hope you find my answer and explanation to be helpful. Happy studying. :)

The function y=log(x) is translated 1 unit right and 2 units down. Which is the graph of the translated function?

SVEN [57.7K]

Given the function $y=\log x.$

1. Translation to the right 1 unit changes the function $y=\log x$ into the function $y=\log (x-1).$

2. Translation 2 units down changes the function $y=\log (x-1)$ into the function $y=\log (x-1)-2.$

3. Two translations change the funcion $y=\log x$ into the function $y=\log (x-1)-2.$

4. The graph of the final function you can see in attached diagram.

a local charity held a crafts fair selling donated,handmade items. Total proceeds from the sale were $1,875. A total of 95 items

Lana71 [14]

15x+25y=1875
Let
y=95-x
15x+25 (95-x)=1875
Solve for x
15x+2375-25x=1875
15x-25x=1875-2375
-10x=-500
X=500/10
X=50 the number of $15 items

Y=95-50=45 the number of $25 items

xxMikexx [17]

Answer:

8 teams

5 girls and 4 boys

Step-by-step explanation:

To determine how many teams we can have , we need to determine the greatest common factor.

girls:40 = 5*8

boys:32 = 4*8

The greatest common factor is 8

So we will have 8 teams

There will be 5 girls and 4 boys on each team
