Answer: The answer is given below
Step-by-step explanation:
From the question, we are informed that the money m (in £) Xavier has to spend each week is his wage w (in £) subtract the tax t (in £) he pays on his income. Therefore, the formula for the money he can spend will be:
m = w - t
The amount of money that he has to spend if he earns £120 a week and pays £41 in tax will be:
m = w - t
m = £120 - £41
m = £79
Answer: 
Step-by-step explanation:
Given the right triangle in the image, you need to remember the following identity:
Observe the triangle. You can identify that:
Then, knowing these values, you can substitute them into :
Finally, you have to solve for "x".
Therefore, the value of "x" rounded to the nearest tenth is:
Answer:
- $5 bills x 5, $1 bills x 10, quarters x 16, dimes x 9
Step-by-step explanation:
- $5 bills = x, total = 5x
- $1 bills = 2x, total = x
- Quarters = 3x + 1, total = 0.25(3x + 1)
- Dimes = 3x + 1 - 7= 3x - 6, total = 0.1(3x - 6)
<u>Equation below as the sum, solve for x:</u>
- 5x + 2x + 0.25(3x + 1) + 0.1(3x - 6) = 39.9
- 7x + 0.75x + 0.25 + 0.3x - 0.6 = 39.9
- 8.05x - 0.35 = 39.9
- 8.05x = 40.25
- x = 40.25/8.05
- x = 5
<u>Number of each bill and coin:</u>
- $5 bills = 5
- $1 bills = 2*5 = 10
- Quarters = 3*5 + 1 = 16
- Dimes = 3*5 - 6 = 9
