Answer:
The last choice: x = 3.
Step-by-step explanation:
M < WYX = 1/2 * 78 = 39 degrees ( angle opposite te arc of 78 degrees).
Therefore m < XWY = 180-114-39 = 27 degrees.
7x + 6 = 27
7x = 21
x = 3.
Answer:
there must me a second equation too. as an equation with two variables can not be solved by just one equation
Answer:
999.60
Step-by-step explanation:
$3.51 times 42 is 147.42 and 1147.02 minus 147.42 is $999.60
TBH this might not be right I'm not great at math buuut- heeeyy
Answer:
x = 4, y = 2
Step-by-step explanation:
Start by multiplying the first equation by 2:
2x + 2y = 12 --> 4x + 4y = 24
Subtract the second from the first:
4x + 4y = 24
- 5x + 4y = 28
4x - 5x = -x
4y = 4y = 0
24 - 28 = -4
so you end with -x + 0 = -4
Solve for x to get x = 4
Plug x = 4 back into 2x + 2y = 12 to find y.
2(4) + 2y = 12
8 + 2y = 12
2y = 4
y = 2
