Answer:

The correct answer is 20.

Step-by-step explanation:

Well, let's see the facts we have.

We know that the factory can produce 12 lawnmowers in 8 hours.

Now what we need to find out is how many hours it will take the factory to do 30 lawnmowers.

Having 3 data resolved and only one icognite, the most convenient thing would be to do a cross-multiplication.

If 8 hours ------ 12 lawnmowers

Then x hours ----- 30 lawnmowers.

x.12 = 30.8

x.12 = 240

x = 240:12

x = 20

With this information we can say that it will take 20 hours for the factory to do 30 lawnmowers.

Factor each of the following expressions into two binomials.
Anestetic [448]
Answer:

Explanation:

1.
x^2 - 10x + 24
= (x - 6)(x - 4)

2.
x^2 - 12x + 27
= (x - 9)(x - 3)

3.
x^2 - 13x + 36
= (x - 9)(x - 4)

4.
x^2 - 5x - 14
= (x - 7)(x + 2)

5.
x^2 + x - 20
= (x + 5)(x - 4)

6.
x^2 - 3x - 40
= (x - 8)(x + 5)

7.
x^2 + 2x - 48
= (x - 8)(x + 6)

8.
x^2 + 10x - 24
= (x - 2)(x + 12)

9.
x^2 - 7x - 44
= (x - 11)(x + 4)

10.
x^2 + x - 2
= (x + 2)(x - 1)

11.
x^2 + 2x + 1
= (x + 1)(x + 1)

12.
x^2 - x - 6
= (x - 3)(x + 2)

How do you find a variable to 4-2(v+9)=26
garik1379 [7]

Answer:

V=20

Step-by-step explanation:

Simplify both sides of the equation.

4−2(v+9)=26

4+(−2)(v)+(−2)(9)=26(Distribute)

4+−2v+−18=26

(−2v)+(4+−18)=26(Combine Like Terms)

−2v+−14=26

−2v−14=26

Step 2: Add 14 to both sides.

−2v−14+14=26+14

−2v=40

Step 3: Divide both sides by -2.

−2v

−2

=

40

−2

v=−20
