-1.5(4-n) + 2.8 - 1.5(4-n) + 2.8
Two ways of solving this, you can just expand and solve, or combine like terms then solve. I will combine like terms.

<span>-1.5(4-n) + 2.8 - 1.5(4-n) + 2.8
</span>(2*-1.5)(4-n) + (2*2.8)
-3(4-n) + 5.6
-3*4 + 3n + 5.6
-12 + 3n + 5.6
3n - 6.4

Rename 5/6 and 5/8 using the least common denominator.

Marina CMI [18]

Answer:

5/6 = 20/24

5/8 = 15/24

Step-by-step explanation:

These are the answers because:

1) First, the least common denominator is 24 because 8 x 3 is 24 and 6 x 4 is 24

2) Next, multiply the numerators with the same number you multiplied with the denominator

5 x 3 = 15

5 x 4 = 20

3) Therefore, the answers are:

5/6 = 20/24

5/8 = 15/24

Hope this helps!

140 tickets sold at the door

Step by Step Explanation:

x = tickets sold in advance
y = tickets sold at the door

We use the formula ax+by=c and a+b=c

x + y = 514
17x + 20y = 9158

y = 514 - x
17x + 20(514 - x)
17x + 10,280 - 20x = 9,158
-3x + 10,280 = 9,158
-3x = -11222
x = 374

This is for tickets sold in advance so we need to find y

374 + y = 514
y = 140

140 tickets were sold at the door
