Answer:
a=2
Step-by-step explanation:
8a +9=3a +19
Subtract 9 from both sides
-9= -9
8a=3a +10
Subtract -3a from both sides
5a=10
5a=10
5a divided by both sides
5/5
10/5=2
a=2
It is 10 times as much as 50
1. 7 + 15 + 12 + 5 + 5 + 10 = 54
54 x 2.5 = $135
The correct answer is $135
2. A^2 + 9^2 = 22^2
A^2 + 81 = 484
A^2 = 403
Square root of a and 403
A= 20.7
20.7 + 22 + 9 = 51.7
The correct answer is (3)
Answer:
All kids at the movie = x
42 / x = .60
x = 42 / .60
x = 70 total kids were at the movie.
Step-by-step explanation:
Answer:
28.9°
Step-by-step explanation:
This is a Trigonometry question
From the above, question,
The horizontal distance = Adjacent = 29 feet
The distance of the kite from the ground = Opposite= 14 feet
We solve using the Trigonometric function of Sine
sin θ = Opposite/Adjacent
sin θ = 14/29
θ = arc sin (14/29)
θ = 28.865727415°
Approximately = 28.9°
Therefore, the angle measure of x = 28.9°
