Which expression can be used to find the value of expression below -(7/10) + 2/8 + 1/10 - (4/8)
maks197457 [2]

Answer:

(-17)/20

Step-by-step explanation:

Simplify the following:

-7/10 + 2/8 + 1/10 - 4/8

The gcd of 2 and 8 is 2, so 2/8 = (2×1)/(2×4) = 2/2×1/4 = 1/4:

-7/10 + 1/4 + 1/10 - 4/8

The gcd of -4 and 8 is 4, so (-4)/8 = (4 (-1))/(4×2) = 4/4×(-1)/2 = (-1)/2:

-7/10 + 1/4 + 1/10 + -1/2

Put -7/10 + 1/4 + 1/10 - 1/2 over the common denominator 20. -7/10 + 1/4 + 1/10 - 1/2 = (2 (-7))/20 + 5/20 + 2/20 - 10/20:

(2 (-7))/20 + 5/20 + 2/20 - 10/20

2 (-7) = -14:

(-14)/20 + 5/20 + 2/20 - 10/20

-14/20 + 5/20 + 2/20 - 10/20 = (-14 + 5 + 2 - 10)/20:

(-14 + 5 + 2 - 10)/20

-14 + 5 + 2 - 10 = (5 + 2) - (14 + 10):

((5 + 2) - (14 + 10))/20

5 + 2 = 7:

(7 - (14 + 10))/20

| 1 | 4

+ | 1 | 0

| 2 | 4:

(7 - 24)/20

7 - 24 = -(24 - 7):

(-(24 - 7))/20

| 1 | 14

| 2 | 4

- | | 7

| 1 | 7:

The ratio of the lengths of two adjacent sides of a rectangle is 1/5. If it's perminiter is 24 then how wide is the rectangle
Mars2501 [29]

Width(w): 1x

Length (L): 5x

Perimeter = 2L + 2w

           24 = 2(5x) + 2(1x)

           24 = 10x + 2x

           24 = 12x

             2 = x

Answer: width = 2

Complete the missing value in the solution to the equation:<br> 7 + 5x = =3(y-2)<br> ( ,5)
mafiozo [28]

Answer:

x = 2/5

Step-by-step explanation:

Given:

7 + 5x = 3(y-2)

Rearrange this equation such that x is expressed in terms of y

7 + 5x = 3(y-2)   (expand right side)

7 + 5x = y(3)-2(3)

7 + 5x = 3y-6   (subtract 7 from both sides)

5x = 3y - 6 - 7

5x = 3y - 13

we are given the y-value of the coordinate pair (? , 5)

simply substitute y=5 into the equation above

5x = 3y - 13

5x = 3(5) - 13

5x = 15 - 13

5x = 2   (divide both sides 5)

x = 2/5
