Do 2x2 first which is 4 and then 5+12 which is 17 . 17/4 is 4.25
The slope is negative, so the slope is negative. Using the rise over run formula, the slope of the line should be -1.
The circumference = 2×pi×radius
the small = 2×3.14×4 = 25.12 inches
the medium = 2×3.14×5 = 31.4 inches
the large = 2×3.14×6 = 37.68 inches
For these problems you have to use PEMDAS so for problem 15 you would do the parentheses first, (21-3) you get 18 and then exponents, 3^2, you get 9, no multiplication but there is division so take your answers, 18 and 9 and divide them, you get 2, so the answer to 15 is 2.
Answer:
15
Step-by-step explanation:
subtract 12 on both sides and you get
x=27-12
x=15
