Answer:
Total laps = 10d
Step-by-step explanation:
Let c = Carl's laps
d = Daria's laps
e = Erin's laps
c = 3d
c = e/2
c + d + e = totals laps
We can insert 3d in place of c in the third equation
3d + d + e = total laps
Also, e/2 equals 3d
e/2 = 3d
Multiply both sides by 2
(e/2 = 3d)2
e = 6d
Insert the new e
3d + d + 6d = 10d = totals laps
Let p = pictures only
let f = pictures with frames
p + f = 100
5p + 10f = 875
Solve for one variable in the first equation then plug into the second
p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75
75 pictures with frames were sold

Answer:
Step-by-step explanation:
1.
Formula for Area of a parallelogram: A = bh
So multiply the base (25cm) by the height (16cm) to get 400cm^2.
2.
Volume formula l x w x h
Multiply the length of the pool (20ft) by the width (15ft) by the height (6ft) to get 1,800ft^2
3.
Formula for Area of a trapezoid A= a+b/2 * h
Where a is (12.6in), b is (15in), and h is (3.4in) just plug in the numbers into the formula to get 46.92in^2
4.
Same thing as number one, use the Area of a parallelogram formula A = bh
