Answer:

-4y + 20

Step-by-step explanation:

4(-y+5)

What we need to do here is get rid of the parentheses, which can be achieved through multiplication.

This is another way of saying 4 times -y plus 4 times 5.

Let's break the the parentheses down into 2 separate formulas.

4(-y) and 4(5)

Now we can multiply these two together to get -4y and +20. When combined, we get -4y +20.

You just need to do 12 1/5 ÷ 1 4/5.
To do this, first convert both fractions to improper fractions or topheavy fractions.

12 1/5 -
15 × 5 is 60, 60 + 1 is 61 so 12 1/5 = 61/5

1 4/5 -
1 × 5 is 5 and 5 + 4 is 9. 1 4/5 = 9/5

To divide fractions, you do keep, chang, flip (keep the 1st fraction, change the ÷ to ×, and flip the 2nd fraction)

the question starts as 61/5 ÷ 9/5 and becomes 61/5 × 5/9

multiplication in fractions is literally just numerator × numerator / denominator × denominator.

61 × 5 is 305. 5 × 9 is 45. the fraction is 305/45.

however, we need a whole number. 305/45 converted into a decimal is 6.7777778 (6.7 recurring). obviously you can't put a fraction of a book onto a shelt, so you round it down to the nearest whole number, which is 6.

final answer: 6

1. Two angles are supplementary. Angle 1 measures
Serggg [28]

Answer:

34 degrees

Step-by-step explanation:

supplementary Angles are pair of angles whose sum is 180 degrees.

Given

Angle 1 = 4x + 6 degrees

Angle 2 = 38 degrees

Condition : angles are supplementary Angles

therefore

Angle 1 + Angle 2 =180

4x+6+38 = 180

=>4x+44 = 180

=> 4x = 180-44

=> 4x= 136

=>x = 34

Thus value of x is 34 degrees.
