To find the unit rate, 391/17 gives us 23$ per hour time 13 hours is 299$ total.
The easiest way think of .36 as 36/100 and then divide by 2's.
36/100
18/50
9/25
Answer:
Try first and last
Step-by-step explanation:
Divide it by 25 witch is the height then find the square root
Answer:
x = 21
y = 114
Step-by-step explanation:
Here, we are to find the values of x and y
Mathematically;
3x - 15 + 6x + 6 = 180
reason for this is that opposite interior angles are supplementary, they add up to 180
9x-9 = 180
9x = 180 + 9
9x = 189
x = 189/9
x = 21
Also;
3x-15 + y + 18 = 180
Reason for this is that angles on a straight line are supplementary
Recall, x = 21
3(21)-15 + y + 18 = 180
63-15 + y + 18 = 180
y = 180-66
y = 114 degrees
