You can solve this by using the system of equations.
Jan - 4.95 = 2H + 3C
Wayne - 5.45 = 3H + 2C
Use elimination.
-3(2H + 3C = 4.95)
2(3H + 2C = 5.45)
Solve. And you'll get:
-6H + (-9C) = -14.85
6H + 4C = 10.9
Cross out -6H and 6H because they cancel out. And you're left with:
-9C = -14.85
4C = 10.9
Add -9C with 4C, and -14.85 with 10.9.
-5C = -3.95
Divide each side with -5.
C = $0.79
Now to figure out what H is, just substitute the C in one of the equations with 0.79.
5.45 = 3H + 2(0.79)
5.45 = 3H + 1.58
-1.58 -1.58
3.87 = 3H
3.87/3 = 3/3(H)
1.29 = H
Finished!

... 6/435 = 2/145
Answer:
B. 3 / (x+6)
Step-by-step explanation:
3(x+2)/(x+6)(x+2) = 3 / (x+6)
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
