Answer:
Ben's
Step-by-step explanation:
If E is the amount of energy that each full set of panels produces, then ...
3 of Ismael's 5 panels produce 3/5E
4 of Ben's 6 panels produce 4/6E
We can compare these fractions when they have a common denominator.
3/5E = 18/30E . . . . energy from Ismael's panels
4/6E = 20/30E . . . energy from Ben's panels
18/30 < 20/30 . . . . so Ben's panels are producing more energy
52.5
Explanation:
x/18. 30/100 cross multiply 30*18=5250
5250 divided by 100= 52.5
72cm
you multiply the outside length (6cm each) by how many there are
Multiply $530.40 by 3/4. You get the equation
If you simplify this, you get the solution of $397.80
$397.80
5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
