Which value of the variable m satisfies the equation 20 = -2(4m - 5)

m = - 1.25

Step-by-step explanation:

20 = - 2(4m - 5) ← divide both sides by - 2

- 10 = 4m - 5 ( add 5 to both sides )

- 5 = 4m ( divide both sides by 4 )

- = m , that is

m = - 1.25

which value of the variable m satisfies the equation 20 = -2(4m - 5)

20 = -2(4m - 5)

20 = -8m + 10

20 = -8m + 10

20 - 10 = -8m + 10 - 10

20 - 10 = -8m + 10 - 10

10 = -8m + 10 - 10

10 = -8m + 10 - 10

10 = -8m

10 = -8m

(Cancel -8, In the numerator and the denominator)

m = -1.25

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
