Answer:
<h2>
50°, 60°, 70° (the second answer)</h2>
Step-by-step explanation:
The sum of the angles in a triangle = 180°
We can use the equation:
2x + 80 + 25 - 5x + 6x + 90 = 180
Combine like-terms:
2x + 6x - 5x = 3x
80 + 25 + 90 = 195
195 + 3x = 180
Subtract 195 from both sides:
3x = -15
Divide both sides by -3 to isolate x:
x = -5
Now that you've solved for x, you can replace x with -5 in the equation for each angle.
2(-5) + 80 = 70°
6(-5) + 90 = 60°
25 - 5(-5) = 50°

Answer:
The correct option is C
Step-by-step explanation:
Lets find the linear equations:
For Hours
Let
Number of hours in bookstore per week = x
Number of hours for babysitting per week = y
Total number of hours ≤ 16
So the first equation us:
x + y ≤ 16
y ≤ 16 - x
For Money
Let
Amount earned per hour from bookstore = $4
Total Amount earned from bookstore = 4x
Amount earned per hour from babysitting = $8
Total Amount earned from babysitting = 8y
Total Amount earned ≥ $56
So the second equation is:
4x + 8y ≥ 56
8y ≥ -4x + 56
y ≥ -(1/2)x + 7
The time × 1.5=the distance
so 5×1.5=7.5
10×1.5=15
20×1.5=30
