The scale drawing is 1 in: 10 ft
There is 45 ft, and you are looking for the amount of inchs.
Divide 45 ft with 10 ft to get inch, which is x
45/10 = x
4.5 = x
4.5 inch is the distance on the drawing, when the actual distance is 45 feet
hope this helps
Answer:
D.
Explanation:
PEMDAS method. First do the parentheses. Multiply first, then subtract 12 from that number. Once finished with the parentheses, multiply by 8.
<u><em>Answer:</em></u>
y = 23
<u><em>Step-by-step explanation:</em></u>
Add the numbers:
18 + 5 - y
= 23 - y
Rearrange terms:
y = 23
Let the angles be x and (180-x).
Let 2x = 180-x.
Then 3x = 180, and x = 60. One angle is 60 degrees and the other is 180-60, or 120, degrees.
