Answer: Tim weighs 90 lbs and his brother weighs 130 lbs
Answer:
$60
Step-by-step explanation:
Jason saved gas money (x). Maria saved $20 more than double what Jason has (20 + 2x). Combined, they saved $200. Solve for x for Jason's amount.
(x) + (20 + 2x) = 200
x + 20 + 2x = 200
3x + 20 = 200
3x + 20 = 200
3x + 20 - 20 = 200 - 20
3x = 180
3x/3 = 180/3
x = 60
Jason saved $60 for this trip.
Answer: do the math, 39x
Step-by-step explanation:2+4=6 times 7=42-19=23+7=30+9=39x
At least one right angle:
A + C + E
At least 2 sides of equal length:
B + C + E
At least one pair of parallel sides:
A + B + E
Surface of the cylinder : 2*(pi*radius^2)+(2*pi*radius*height)=2(pi*1.5^2)+(2*pi*1.5*9)=31.5pi cm^2 ~99 cm^2
Volume : pi*radius^2*height=pi*1.5^2*9=20.25pi~64 cm^3
