Answer:
x = -4
Step-by-step explanation:
First lets add 82 + 55 which equals 137, then 137 +47 which equals 184
Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.
-x + 184 = 180
-x = -4
Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.

Answer:
Step-by-step explanation:
Where x represents the previous year's salary, its amount this year is said to be ...
x + 2000
The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:
0.07(x +2000) = 3290
__
Solving for x, we find ...
x = (3290/0.07) -2000 = 45000
Sandra's salary the previous year was $45,000.

Answer:
x = -5
y = -2
Step-by-step explanation:
<em><u>Since you have y, plug that into the equation:</u></em>
-2x - 7y = 24
-2x - 7(-2) = 24
-2x + 14 = 24
<u><em>Then, subtract 14 from both sides:</em></u>
-2x + 14 = 24
- 14 - 14
__________
-2x = 10
<u><em>Finally, divide both sides by -2:</em></u>
-2x = 10
x = -5
So now you have, x = -5 and y = -2.
Answer:
Step-by-step explanation:
2(x-1)=50, lets multiply
2x-2=50 add 2 in both sides
2x=48
x=24
your options are weird, unless you mean (x-1)^2 ?
