Answer:
24°
Step-by-step explanation:
the total angle, made up from both a and 66°, is a mini-square, as you can see. this represents a right angle of 90°
thus, a and 66° combine to make 90°
a + 66° = 90°
subtract 66 from both sides to get a
a = 24°
A, because:
Hardcover: 0.35
Buys hard cover and non-fiction: 0.35 x 0.55 = 0.1925
-5/3
When a slope is over the x-axis, it will be positive. If it is below the x-axis, it will be negative.
Answer: 112 km
=====================================================
Work Shown:
(5 miles)/(8 km) = (70 miles)/(x km)
5/8 = 70/x
5*x = 8*70 ... cross multiply
5x = 560
x = 560/5 .... divide both sides by 5
x = 112
According to the given estimation, 70 miles converts to 112 km.
The more accurate conversion is approximately 70 miles = 112.65408 km, so this estimation isn't too far off.
Answer:
7 is the value of x.
Step-by-step explanation:
Now we have to,
find the required value of x.
→ -18x - 19 = -145
→ -18x = -145 + 19
→ -18x = -126
→ x = -126/-18
→ [ x = 7 ]
Hence, the value of x is 7.
