Answer:

x= -2

Step-by-step explanation:

4x + 2 = 6(-2x - 5)

Distribute

4x+2 = -12x-30

Add 12x to each side

4x+2+12x = -12x-30+12x

16x+2 = -30

Subtract 2 from each side

16x+2-2=-30-2

16x = -32

Divide by 16

16x/16x = -32/16

x = -2

Solve for m. 7/10=r-(-8/5)
Eddi Din [679]

Answer:

-9/10 =r

Step-by-step explanation:

7/10=r-(-8/5)

Subtracting a negative is like adding

7/10=r+(8/5)

Subtract 8/5 from each side

7/10 - 8/5=r+(8/5) - 8/5

7/10 - 8/5 = r

Get a common denominator

7/10 - 16/10 = r

-9/10 =r

A b and c lie on a straight line given that angle y = 125 and angle z = 313 work out x
inysia [295]

Answer:

∠x = 78

Step-by-step explanation:

∠y + ∠1 = 180

=> 125 + ∠1 = 180

=> ∠1 = 180 - 125

=> ∠1 = 55

∠z + ∠2 = 360

=> 313 + ∠2 = 360

=> ∠2 = 360-313

=> ∠2 = 47

∠1 + ∠2 + ∠x = 180

=> 55 + 47 + ∠x = 180

=> ∠x = 180 - 55 - 47

=> ∠x = 78
