Answer:
x=0.55
Step-by-step explanation:
-7x -3x + 2 =8x -8
-10x+2=8x-8
2+8=8x+10x
10=18x
10/18=x
x=0.55
Answer:
b = 43
Step-by-step explanation:
So let's plug things in first:
y= 2x - 20 and y= -5x +b which can become →
2x - 20 = -5x + b (now you said that x=9 so let's plug that in)
2(9) -20 = -5(9) + b (now try solving that)
18 -20 = -45 + b → -2 = -45 + b ( so then add 45 to both sides)
43 = b ( and there's your answer )
Answer:
A
Step-by-step explanation:
Answer:
x = 50
Step-by-step explanation:
I guess, this diagram tells us that the lines are parallel.
that means that they cut the third line at the exact same angles.
and that means
3x - 26 = 2x + 24
x - 26 = 24
x = 50
21+3x=-15
3x=-15-21
3x=-36
x=-36/3
x=-12
