A and B because they both have the same angle
Answer:
The number is -2.
Step-by-step explanation:
From the word problem, we can figure out the equation for the unknown number (x).
8x-3=-19
We would then work out the equation to find x.
Add 3 to -19.
8x=-16
Divide -16 by 8.
x=-2
Answer: w = 7, x = 6
Step-by-step explanation: Solve by substitution
W + b = 13
rewrite as b = 13 - w and substitute that value for b in the second equation
6.5w + 2b = 57.5 Then solve for w
6.5w + 2(13-w) = 57.5 . Distribute
6.5w + 26 - 2w = 57.5 . Subtract 26 from both sides. Combine like terms and simplify
6.5w - 2w = 57.5 - 26
4.5w = 31.5 Divide both sides by 4.65
w = 7 . Substitute 7 for w in the first equation and solve for b
7 + b = 13 . Subtract 7 from both sides
b = 6
Answer:
10 times
Step-by-step explanation:
Because these are opposite and they both have complimentary angles, you can set them equal to each other and solve for x
