Answer:
No solution
Step-by-step explanation:
To solve first you need to isolate the absolute value sign. Do this by subtracting 7 from each side.
Now an expression inside absolute value bars is set to a negative. Since absolute value makes terms and expressions positive, there is no x-value that could make this true. Therefore, there are no solutions.
Answer:
3.75
Step-by-step explanation:
By Basic Proportionality Theorem:
2x + 3x + 3x + 12 = 180° [Sum of all angles of a triangle is 180°]
=> 7 x = 180° - 12°
=> 7 x = 168°
=> x = 
°
=> x = 24°
? = 2x + 3x
=> 2×24° + 3×24°
=> 48° + 72°
<h3>=> 120°</h3>

Denote points:
- G - gas station;
- M - motel;
- S - sister's home.
These three points lie on the same line in order M, G and S. The distance MS=341 mi and MS=GM+GS.
It takes Doug 3 hours to go to a motel from gas station (GM) and it takes 2.5 hours Ashley to go to a sister's home from gas station (GS). The total time is 3+2.5=5.5 hours.
Then using the formula d=rt, you can conclude that
341=5.5·r,
r=341:5.5,
r=62 mi/h.
Answer: 62 mi/h.
The ratio 7: 2 means the total loaves of loaves to the total loaves of rye bread.
total loaves : Rye
7 : 2
