A. 3x + 12
B. US$ 34.50
Correct question and statement: Three friends went to lunch. They all ordered the same meal. At the end of lunch they gave the waiter a $12 tip.
A. Write a algebraic expression to represent the situation.
B. How much total money was spent if each meal cost $7.50?
Source: Previous question found at brainly
Step-by-step explanation:
A. If the three friends ordered the same meal, we have then:
x = Cost of the meal
Tip = US$ 12
<u>3x + 12 </u>
Total of the meal would be three times the cost of the individual meal, x, plus the tip.
B. Given that x = 7.50, how much was the total cost?
Let's use the equation we wrote in part A.
3x + 12
3 (7.50) + 12
<u>22.50 + 12 = 34.50</u>

Answer:
C. $875
Step-by-step explanation:
The rule of housing is the rule of thumb of not using more than 25% of your gross income. This means that the households supposed limited expenses on housing would be a maximum of 25% only.
So to find the monthly housing budget of Bryson, we simply take his annual salary and multiply it by 25% or 0.25 and then divide the product by 12.
Monthly Housing Budget = ($42,000 * 0.25)/12
Monthly Housing Budget = 10500/12
Monthly Housing Budget = $875
Answer:
x = 3.4
Step-by-step explanation:
recall that for a right angle with an internal angle θ,
cos θ = adjacent length / hypotenuse
in our case,
θ = 55 deg
adjacent length = x units
hypotenuse = 6 units
substitute these into the formula above
cos θ = adjacent length / hypotenuse
cos 55 = x / 6 (multiply both sides by 6)
x = 6 cos 55 (use calculator)
x = 3.4415
x = 3.4 (rounded to nearest tenth)
This = number of green apples / total number of apples
= 3/7
