Answer:

An example below

Step-by-step explanation:

5(4a + 7(a + 2b))

First simply the inside bracket using distributive property:

7(a + 2b)

7(a) + 7(2b)

7a + 14b

5(4a + 7a + 14b)

5(11a + 14b)

Use distributive property again

5(11a) + 5(14b)

55a + 70b

Answer:

x= -2

Step-by-step explanation:

An example could be

10 ( x+2) + 3(x+4) = 6(x+3)

Distribute

10x+20 +3x+12 = 6x+18

Combine like terms

13x +32 = 6x+18

Subtract 6x from each side

13x-6x +32 = 6x-6x+18

7x +32 = 18

Subtract 32 from each side

7x +32-32 = 18-32

7x =-14

Divide by 7

7x/7 = -14/7

x = -2

Ierofanga [76]

Answer: 30%


Step-by-step explanation:

The first step is to find the increase in numbers

26-20= 6

Now you find the percent. This means you're looking for the percent 6 is equal to when compared to 20. The easiest way is to divide the increase by the original number

6/20= 0.3

To convert that to percent, multiply it by 100

0.3 * 100= 30%

There was a 30% increase.

7(x−5)−9=334 what is the answer of x
slega [8]

Answer:

\boxed {x = 54}

Step-by-step explanation:

Solve for the value of x:

7(x - 5) - 9 = 334

-Use <u>Distributive Property</u>:

7(x - 5) - 9 = 334

7x - 35 - 9 = 334

-Combine like terms:

7x - 35 - 9 = 334

7x - 44 = 334

-Add both sides by 44:

7x - 44 + 44 = 334 + 44

7x = 378

-Divide both sides by 7:

\frac{7x}{7}= \frac{378}{7}

\boxed {x = 54}

Therefore, the value of x is 54.
