Which value of x is in the solution set of -3X+8≥14? ) A. -3 B. -1 C. 0 D. 3 ​
romanna [79]

Answer:

A

Step-by-step explanation:

Solving for x:

-3x + 8 ≥ 14

-3x ≥ 6

x ≤ -2

Notice the sign gets reversed when you divide or multiply by a negative number.

The only option less than -2 is -3, A.

Here's a tip: on multiple choice questions, sometimes it's faster to try each answer instead of solving the equation.  This can save time on tests like the SAT or ACT.

Let's try it:

-3(-3) + 8 = 9 + 8 = 17

-3(-1) + 8 = 3 + 8 = 11

-3(0) + 8 = 0 + 8 = 8

-3(3) + 8 = -9 + 8 = -1

So you can see the answer is A.

Mr. Jones wants to buy 6 tickets to a play. Each ticket costs $10. Mr. Jones has $45 in his pocket.
lawyer [7]

Answer:

He needs $15 more

Step-by-step explanation:

since each ticket costs $10 dollars, and there is 6 tickets, we need to multiply 10 x 6 to get the total cost of all tickets

10 x 6 = $60

To find how much more money he needs to buy all tickets, we need to subtract $45 from the total cost of tickets, which is $60

$60 - $45 = $15

Hope you understand this explanation!
