Factor completely: 10ax + 5bx - 8ay - 4by
kiruha [24]
The answer is (5x - 4y)(2a + b)

10ax + 5bx - 8ay - 4by = 10ax + 5bx - (8ay + 4by) =<span>
                                      = 5x * 2a + 5x * b - (2a * 4y + b * 4y) =
                                      = 5x(2a + b) - 4y(2a + b) = 
                                      = (5x - 4y)(2a + b)</span>

Solve by Elimination:<br> 8x + 6y = -5<br> 10x + 6y= -13
jonny [76]

Answer:

x= -4 and y= 27/6

Step-by-step explanation:

-(8x + 6y = -5) which converts to -8x -6y = 5

10x + 6y = -13

simplify from there

-8x + 10x = 2x ; -6y + 6y = 0 ; 5 - 13 = -8

soo, now you have

2x = -8

x = -4

then, plug in to find y

8(-4) + 6y = -5

-32 + 6y = -5   add 32 on both sides

6y = 27    divide both sides by 6

y= 27/6 or 4.5

The bagel shop has the better price because 1 dozen is 12 bagels and if you multiply 0.75 x 12 = 9.00
so the better price is 7.00

Find the volume of this composite figure and explain how you got your answer
Damm [24]
To solve this, we work out the volume of the two shapes (the cuboid and the pyramid) and then add them together.

We get the volume of the cuboid by multiplying the base by the width by the length:

Volume of cuboid = 6 x 6 x 4 

                               = 144m³

Now to get the volume of the pyramid, we multiply the base by the length by the height, and then we divide by three.

Volume of pyramid = 6 x 6 x 8 
÷ 3
                                    = 96m³
-------------------------------------------------------------------------------------------------------------
Answer:
Now that we know the two volumes, we simply add them together:

144 + 96 = 240m³

So the volume of the composite sold is 240m³
