Answer:
Step-by-step explanation:
3h - 8h + 10 = 10 - 5h
-5h + 10 = 10 - 5h
10 = 10
infinitely many solutions
That would be 37.5 percent
Answer:
The greatest number of people that can attend the meeting on that budget is 116
Step-by-step explanation:
The cost for the meeting is given by the following expression:
cost = 500 + 6*person
Since the budget is $1200 the cost must be at most equal to that, therefore:
1200 = 500 + 6*person
500 + 6*person = 1200
6*person = 1200 - 500
6*person = 700
person = 700/6 = 116.667
Since there can't be a 0.667 person, the greatest number of people that can attend the meeting on that budget is 116
Answer:
<h3>15%</h3>
Step-by-step explanation:
<h3>First , We will solve their daily Income </h3>
• Income = spends / rate
• Income = 600 / 40%
• Income = 600 / 0 .40%
• Income = 1500
Thus , Their daily Income is 1500 . Now ,We will solve for the rate of the Allowance .
• Rate = spent / Income
• Rate = 225 / 1500
• Rate = 0.15
• Rate = 15%
Therefore, the percent of the family's daily Income of the Allowance of their children's is 15%

5x + 2y = 7 . . . (1)
y = x + 1 . . . (2)
Putting (2) into (1) gives
5x + 2(x + 1) = 7 => 5x + 2x + 2 = 7 => 7x = 7 - 2 = 5 => x = 5/7
From (2) y = 5/7 + 1 = 12/7
Therefore, solution is {(5/7, 12/7)}
