Monica [59]

Student P:

They messed up in step 1 because they made the 7.75 positive instead of negative, which causes the entire solution to be wrong

Student Q:

They were correct up until step 3. They didn't take all the negatives out of the equation (ex. -(3.5+7.75+29.67)).

Complete set:

From the picture, it looks like the original problem was

-2.5(1.4+3.1)+6.9(-4.3)

Step 1: multiply

1.4(-2.5)+3.1(-2.5)+6.9(-4.3)

Step 2: subtract (add?) them all together

-3.5-7.75-29.67

Step 3 should equal -40.92

bagirrra123 [75]

Answer:

132 people bought balcony tickets and 450 bout ground tickets

Step-by-step explanation:

let x be balcony and y for ground

x+y=582

15x+10y=6480  solve by adding(subtracting)/eliminating process

multiply first equation by 15 to eliminate x:

15x+15y=8730

15x+10y=6480      subtract

15x+15y-15x-10y=8730-6480

5y=2250

y=2250/5=450

x+y=582

x=582-450=132
