Multi step problems what is -10(10+b)=5(3b+5)

b= -5

Step-by-step explanation:

-10(10+b)=5(3b+5)

Distribute

-100 -10b = 15b +25

Add 10b to each side

-100-10b+10b = 15b+10b +25

-100 = 25b+25

Subtract 25 from each side

-100-25 = 25b+25-25

-125 = 25b

Divide by 25

-125/25 =25b/25

-5 =b

its the fourth option

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
