Y=3x+18 <br> -12x+4y=-24 linear system of equations

solong [7]

Answer:

Step-by-step explanation:

Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x

-12x+12x+72=-24

The xs cancel, which leaves you with 72=-24

Since 72 cannot equal -24 there is no answer to this system of equations

The student council at Lincoln Middle School is hosting a school dance. The student council paid $560 for all of the supplies ne

Dovator [93]

Answer:

a) 7t - 560 ≤ 140 is the required inequality to represent the situation.

Step-by-step explanation:

Let t represent the number of tickets sold.

The amount allocated by school council for all supplies = $560

The selling price of each ticket = $7

The aim to earn profit = more than $140

Goal reached if Number of tickets sold = 100

Now, SP of each ticket is $7

⇒Selling price of t tickets = t x ($7) = 7t

PROFIT = TOTAL SELLING Price - TOTAL COST

or, $140 = 7t - $560

According to the question:

7t - 560 ≤ 140

if t = 100, then the profit earned = 7(100) - 560 = 140

Hence, t = 100 is the possible solution of the given expression.
