Answer:
58°
Step-by-step explanation:
<u>Start with the equation</u> 2x + 2 + 90 = 148
<em>( I got the 90 from Angle B since it is a right angle.)</em>
<u>Combine like terms</u> 2x + 92 = 148
<em>( 90 and 2 didn't have variables so you could add them together.)</em>
<u>Subtract 92 from both sides</u> 2x + 92 = 148
-92 -92
<em>(The opposite of addition is subtraction.)</em>
<u>Now write out the new equation</u> 2x = 56
<u>Divide both sides by 2</u> 
= 
<u>You'll end up with...</u> x = 28
<u>To find the measure of angle BAC, plug in 28 where the x value is</u> 2(28) + 2
<u>This gives you the answer</u> 58°

Step-by-step explanation:
Answer:
x ≤ 13
Explanation:
The dot is filled in which means it is equal to 13, and since the arrow is pointing towards the numbers less than 13, x is less than or equal to 13.
Answer:
Step-by-step explanation:
The admission to the fair is $5 and the cost per ride is 50 cents.
Let the number of rides that he can go on be x
If one ride costs 50 cents, x rides will cost 50×x = 50x cents. Converting 50 cents to dollar, it becomes 50/100 = $0.5.
So x rides will cost $0.5x
If his parents gave him $20, he will pay $5 to be admitted into the fair. He would be left with 20- 5 = $15
The equation to find how many rides he can go on will be
0.5x = 15
Since one ride costs $0.5
x rides cost $15
x = 15/0.5 = 30
He can go on 30 rides
