(T+10.5) + 2t + 90 = 180

Masja [62]

Answer:

x = 26.5

Step-by-step explanation:

Step 1: Write equation

(t + 10.5) + 2t + 90 = 180

Step 2: Solve for t

Combine like terms: 3t + 100.5 = 180

Subtract 100.5 on both sides: 3t = 79.5

Divide both sides by 3: t = 26.5

Step 3: Check

Plug in x to verify it's a solution.

Substitute: (26.5 + 10.5) + 2(26.5) + 90 = 180

Parenthesis: 37 + 56 + 90 = 180

Add: 180 = 180

∴ x = 26.5

Answer:

reserved tickets = 6 and general admissions tickets = 15

Step-by-step explanation:

$25r + 10g = 150$

Use two variables to make the equation r for reserved tickets and g for general admission. Reserved cost 25 so put that with r and general cost 10 so out that with g. Since he has 150 to spend the equation will equal 150.

Set r equal to 0 since he isn't buying reserved tickets and only general. Solve for g

$25(0) + 10g = 150 \\ 10g = 150$

divide both sides by 10

$\frac{10g}{10} = \frac{150}{10} \\ g = 15$

Now set g equal to zero since he isn't buying any general tickets. Solve for r.

$25r + 10(0) = 150 \\ 25r = 150$

divide both sides by 25

$\frac{25r}{25} = \frac{150}{25} \\ r = 6$
