Answer:
answer for question 7. 0.17×70 = $11.9
4x+4(3)+4(2)=y
4x+20=y
X equals the amount it cost for each ticket which is unknown. Y equals the total cost. Because the amount of the food is provided, it can be calculated unlike the tickets which is just left at 4x. The work for the snacks are upwards. Its mostly substitution.
Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
4(x - 2) = 3x + 1
Step 2: Solve for <em>x</em>
- <u>Distribute 4:</u> 4x - 8 = 3x + 1
- <u>Subtract 3x on both sides:</u> x - 8 = 1
- <u>Add 8 to both sides:</u> x = 9
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
- <u>Substitute:</u> 4(9 - 2) = 3(9) + 1
- <u>Parenthesis (add):</u> 4(7) = 3(9) + 1
- <u>Multiply:</u> 28 = 27 + 1
- <u>Add:</u> 28 = 28
Using proportions, it is found that:
- Each of Brendan and Clair get R 1387.5.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount.
In this problem, the total amount divided is R 4625.
For every R4 Andrew gets, both Brendan and Clair gets R3, hence the ratio is 4:3:3, which means that:
- Andrew gets
of the total amount.
- Brendan gets
of the total amount.
- Clair gets
of the total amount.
Then:


Hence:
- Each of Brendan and Clair get R 1387.5.
