Answer:
1. 3x - 24 = 6
2. 3x = 30
3. x = 10
Step-by-step explanation:
1. 3 times x is 3x, 3 times 8 equals 24, hence 3x - 24
2. Add 24 to both sides to get rid of -24, getting you 3x = 30
3. Divide by 3 on both sides to even out the x, giving you x = 10
It is B because have you do 160+77-x=180 you would add the like terms 160+77=237 and then subtract 180 from 237 and you get 57 for x and when you plug that in 160+77-57 77-57=20 and 20 plus 160 is 180 so The answer is B)No of these
Answer:
129.25
Step-by-step explanation:
Area of the rectangle
Area = L * W
L = 10
W = 9
Area = 9 * 10 = 90
Area of the1/2 circle
Area of a whole circle = pi * r^2
Area of a 1/2 circle = pi * r^2 /2
d = 10
r = d/2
r = 10/2
r = 5
Area of the 1/2 circle = 3.14 * 5^2 /2 = <u> 39.25</u>
Total 129.25
