Answer:
He must earn $2,400 to cover both leisure and $2,160 for school expenses.
Step-by-step explanation:
Let the total amount Ken must earn be k. Then 10% of that would cover leisure activities and the remaining 90% specifically for school expenses.
Then 0.90k = $2,160, and k = $2,400.
He must earn $2,400 to cover both leisure and $2,160 for school expenses.
28x + 44y = 964.40
21x + 33y = 723.30
Let's multiply the first equation by 4 and the second by -4
84x + 176y = 3857.6
-84x - 132y = -2893.2
Add the equations together.
0 + 44y = 964.4
Simplify
44y = 964.4
Divide both sides by 44
y = 964.4/44
Since we have the value of y, let's plug 964.4/44 into y for the first equation.
28x + 44(964.4/44) = 964.40
Simplify the left side
28x + 964.4 = 964.4
Subtract 964.4 from both sides
28x = 0
Divide both sides by 0
x = 0
In conclusion,
y = 964.4/44
x = 0
Answer:
The correct answer is C if the answers are the same as the picture attached.
Answer:
420 inches or 35 feet of trim is needed for 5 desks.
Step-by-step explanation:
We know that one desk requires 84 inches, so we need to find out how many inches are needed for 5 desk.
If we know one desk needs 84 inches then we have 1 desk = 84 inches.
To get 5 desk, we need to multiply both sides by 5.
1 desk = 84 inches. (multiply by 5 for both sides)
5 desks = 84 * 5
5 desks = 420 inches
We know now that 5 desks require 420 inches, but many people use feet instead.
There are 12 inches in 1 foot, so we need to divide 420 inches by 12 inches to get how many feet we need.
420/12 = 35 feet.
Hope this helps!
<u>Define x:</u>
Let the number of children tickets be x.
Children tickets = x
Adult tickets = 2x
<u>Construct the equation:</u>
4x + 7(2x) = 108
4x + 14x = 109
18x = 108
x = 6
x = 6
2x = 12
Answer: 6 children tickets and 12 adult tickets.
