Answer:

x > -4

Step-by-step explanation:

Isolate the variable, x. Treat the greater than sign like a equal sign, in that what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 7 from both sides:

3x + 7 (-7) > -5 (-7)

3x > - 5 - 7

3x > -12

Next, isolate the variable, x, by dividing 3 from both sides:

(3x)/3 > (-12)/3

x > (-12)/3

x > -4

x > -4 is your answer.

If Mason wants to consider his short-term and long-term goals, which question should he ask? If I buy this bike, will I give up

melamori03 [73]

Answer: Second option is correct.

Step-by-step explanation:

Short term goals are those goals which are meant for short period that is not more than one year.

Long term goals are those goals which are meant for long period that takes more than 4 to 5 years.

So, He should ask " Do I want this bike this month, or should I save up over the summer? "

Here, purchasing a bike is short term goal or saving money is long term goal.

Hence, Second option is correct.
