I believe the answer is -5/3

Y+2x=-1 could become y=-2x-1 and then set that and x+4 equal to each other -2x-1=x+4 and add 2x to both sides to get -1=3x+4 and subtract by 4 on both sides to get -5=3x then divide by 3 and get -5/3=x

Solve 10(1 + 3b) = −20, justifying each step with an algebraic property.
Delicious77 [7]
The correct answer is B = -1

10(1 + 3B) = -20

10 + 30B = -20

-20 - 10 = -30

30B = -30

B = -1


Hope this helps :)

find the two angle measures from the diagram 12x-18 8x +10 answers are 114 and 66 or 66 and 66 or 114 and 114 will mark brainies
MArishka [77]

Answer:

<h2>66 and 66</h2>

Step-by-step explanation:

opposite angles are equal

12x - 18 = 8x + 10

combine similar terms:

12x - 8x = 10 + 18

4x = 28

x = 28/4

x = 7

plugin the value of x=7 back into the equation to solve the angle

= 12x - 18

= 12(7) - 18

= 66

= 8x + 10

= 8(7) + 10

= 66
