Answer:
hope it helps!
Step-by-step explanation:
Perimeter includes three sides of rectangle:
15m + 12m + 15m
Plus half of circle with diameter 12m
Circumference = diameter * PI
Circumference = 37.68m.
1/2 circumference = 18.84m
Total perimeter is 15m+12m+15m+18.84m
60.84m
Answer:x in (-oo:+oo)
(7/2)*x+(1/2)*x = (5/2)*x+101/2 // - (5/2)*x+101/2
(7/2)*x+(1/2)*x-((5/2)*x)-(101/2) = 0
(7/2)*x+(1/2)*x+(-5/2)*x-101/2 = 0
3/2*x-101/2 = 0 // + 101/2
3/2*x = 101/2 // : 3/2
x = 101/2/3/2
x = 101/3
x = 101/3
Step-by-step explanation:
Answer would be 11/4
4x - 2 - 1 = 2
4x - 2 = 2 + 1
4x - 2 = 3
4x - 2 = 9
4x = 9 + 2
4x = 11
x = 11/4
Answer:
6 plus 6 is 12 and 6 plus 6 is 12 so you subtract which would be 6 positive
Step-by-step explanation:
When adding two numbers with like signs, add the values and keep the common sign. When adding two numbers with unlike signs, subtract the values and use the sign of the larger-valued number. Change the subtraction operator to addition and change the sign of the number that immediately follows.
