Answer:

-9/22

Step-by-step explanation:

Cross multiply 3x+1 and x-5 to get 3x^2-14x-5

Cross multiply 3x+2 and x+2 to get 3x^2+8x+4

3x^2-14x-5=3x^2+8x+4

-14x-5=8x+4

-22x=9

x=-9/22

Evaluate when x = 2 and y = 5: 2 + (12 - 5x): 2g

Lemur [1.5K]

Just substitute x = 2 and y = 5 into the equation wherever you see x and y.

2 + (12 - 5x) · 2y

2 + (12 - 5(2)) · 2(5)

2 + (2) · 10

4 · 10

40, is the answer which should be the first box.

Pls I need help and a explanation

Answer:

20) 7/16 = 0.4375

21) 1/6 = 1.6 repeating

22) 2 4/5 = 2.8

23) 98 2/3 = 98.6 repeating

24) 0.8 = 4/5

25) 26 1/5

26) 72.1 repeating = 72 1/9

27) 0.505 = 101/200

Explanation:

To convert fraction into decimal, divide the numerator by the denominator and that's your answer. For example:

7 ÷ 16 = 0.4375.

To convert a decimal into a fraction, place the number after the decimal point over the number place it's in. For example: If you look at 0.8 , 8 is in the tenths place, so you place it over 10 like this 8/10, and then you simplify. Half of 8 is 4 , and half of 10 is 5, so you'd have 4/5.

For #27, since 505 in 0.505 , is in the thousandths place, you'd put it over 1,000 like this 505/1000 and then you simplify. Look at image above to learn how to simplify 505/1000.⤴⤴⤴
