The High School is selling tickets to its Spring Concert. Adult tickets cost $4 and student tickets cost $2.50. 900 tickets are sold and the school makes $2820. Which system of linear equations represent this situation. A. A + 5 = 2820 A + 2.50S =900
b.4A + 2.50S = 2820 A + S = 900
с. A + 2.50S = 2820 4A+ S= 900
d.4A + 2.50S = 900 A +S= 2820

you would need to know all the numbers that are on there

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
