1. 4(x + 3) = 4x + 12
2. -7(4 - y) = -28 + 7y
3. 6(3x + 5y - 4) = 18x + 30y - 24
4. (9a - 3) / 3 = 3a - 1
5. (0.4(0.3m + 0.6n) / 1.2) = (0.12m + 0.24n) / 1.2 = 0.1m + 0.2n
6. -9 2/3(-2 1/4a + b + 8 1/4) = 21 3/4a - 9 2/3b - 79 3/4)
7. 64x + 24.....GCF = 8.......8(8x + 3)
8. -5y - 35......GCF = -5.....-5(y + 7)
9. 36 - 8z.......GCF = 4.......4(9 - 2z)
10. 54n - 81...GCF = 27......27(2n - 3)
11. -2x + 5......-2(x - 5/2)
12. 3x - 8 .......3(x - 8/3)
13. -1/2x + 6....-1/2(x - 12)
14. -x - 10.......-x(1 + 10)

Write the pair of fractions as a pair of fractions with a common denominator |

trapecia [35]

Answer:

3/10 and 2/5 = 3/10 and 4/10

1/3 and 3/4 = 4/12 and 9/12

Step-by-step explanation:

For 3/10 and 2/5

* Find the lcm (least common multiple) of the denominators which are 10 and

5. The multiples of 10 are: 10, 20, 30 etc and the multiples of 5 are: 5, 10 15,

etc. So, the lcm is 10. It is the smallest multiple that the denomitaotrs share.

* Next multiply the numerators (3 and 2) by whatever number you use to

multiply the denominator by to get 10. For 3/10, the denominator stayed the

same, so to get 10, you need to multiply 10 by 1. Do the same for the

numerator. 3 x 1 = 3. So, the first factor pair is 3/10.

* The second factor pair is 2/5, so we are still using the lcm of 10. So, what

do you need to multiply 5 by to get 10? The answer is 2. Now just multiply

the numerator (2) by 2 and you get 4. The second factor pair is now 4/10.

2. Jessica's financial advisor believes that she should spend no more than 28% of her gross monthly income for housing. She has

scoray [572]

Jessica's annual salary is $68571.43.

Data;

percentage saved for housing = 28%
amount saved annually = $1600

<h3>Percentage</h3>

This is the ratio of a number to the entire value and multiplied by 100

The percentage set aside for housing is given as 28% which is $1600.

Let find 28% of x which is equal to 1600

$\frac{28}{100} = \frac{1600}{x}$

cross multiply both sides and solve for x

$\frac{28}{100} = \frac{1600}{x}\\ 28*x = 100*1600\\28x = 160000\\$

Divide both sides by the coefficient of x

$\frac{28x}{28} = \frac{160000}{28}\\ x = 5714.28$

Her monthly income is $5714.28.

Let's multiply this by 12 (months in a year) to determine her gross monthly income.

$5714.28*12 = 68571.43$

From the above calculations, Jessica's annual salary is $68571.43.
