Can someone help me asap <br>I attempted to do it so just ignore that part

Sladkaya [172]

Answer:

a = 180° -73°

b = 73°

c = 180° -73°

Step-by-step explanation:

73° and b are vertical angles, so are congruent (equal).

a and c are equal to each other and each is a linear angle with 73°, so is the supplement of that angle. You could write the equation as ...

a + 73° = 180°

but I prefer to get to the heart of it. The values of a and c are the difference between 180° and 73°.

Solve for x: 3x − 2 > 5x + 10. (5 points)<br> 1) x > 6<br><br> 2) x −6

san4es73 [151]

Answer:

$x$

Step-by-step explanation:

$3x-2>5x+10$

Add 2 to both sides

$3x-2+2>5x+10+2$

Simplify

$3x>5x+12$

Subtract $5x$ from both sides

$3x-5x>5x+12-5x$

Simplify

$-2x>12$

Multiply both sides by $-1$ (reverse the inequality)

$(-2x)(-1)$

Simplify

$2x$

Divide both sides by $2$

$\frac{2x}{2}$

Divide the numbers: $\frac{2}{2} =1$

$=x$

Divide the numbers: $\frac{-12}{2}$

Apply fraction rule: $\frac{-a}{b} =-\frac{a}{b}$

$=\frac{12}{2}$

Divide the numbers: $\frac{12}{2} =6$

$=-6$

$x$

Can someone please help me. It's for the elimination method.

mojhsa [17]

Since there is 101 Tickets,
Let S + A = 101
1.50S + 2.50A = $186.50

Adults + Students = 101

$186. 50 = $2.50 Adults + $1.50 Students

Answer is 35 Adults, and 66 Students.

Hope that helps!!!
