WILL GIVE BRAINLIEST. Tickets to a show cost $3 for students and $7 for adults. If 250 tickets were sold and ticket sales totale

Diano4ka-milaya [45]

Answer:

88 adult tickets were sold

Step-by-step explanation:

3s + 7a = 1102

(s + a = 250)-3

3s + 7a = 1102

+ -3s - 3a = -750 Add these equations together

4a = 352 Divide both sides by 4

a = 88

Now plug this into the second equation

s + a = 250

s + 88 = 250

- 88 - 88 Subtract 88 from both sides

s = 162

If this answer is correct, please make me Brainliest!

Abraham has visited country somebody he has a cold or visiting at least 50 countries he plans to choose a school by visiting fiv

Ipatiy [6.2K]

Question:

Abraham has visited at least 50 countries; he plans to visit five new countries per year (Y) for the next several years. Which inequality and solution shows the amount of years they will take for Abraham to meet his goal.

Answer:

$Countries \geq 50 + 5y$

$y \leq 29$

Step-by-step explanation:

Given

$Countries = 50$ ------ at least

$Yearly =5$

Required

Represent as an inequality

"at least" means $\geq$

So the countries he has visited can be represented as thus;

$Countries \geq 50$

1 year = 5 countries

y years would be 5y countries

So, in y years; he'd have visited

$Countries \geq 50 + 5y$

To determine the value of y.

We have that

$Countries = 195$ in the world

Substitute 195 for Countries

$195 \geq 50 + 5y$

Collect Like Terms

$195 - 50 \geq 5y$

$145 \geq 5y$

Divide through by 5

$145/5 \geq y$

$29 \geq y$

Reorder

$y \leq 29$

This means that; he'll visit all countries in at most 29 years' time
