Solve for x. x/8 - 2 = -3

Mathematics
1 answer:
victus00 [196]3 years ago
5 0

Answer:

The correct answer is x = -8.

Step-by-step explanation:

To solve this equation, we want to get the variable x alone on the left side of the equation.  To do this, we should first add 2 to both sides of the equation.

x/8 - 2 = -3

x/8 -2 + 2 = -3 + 2

x/8 = - 1

Next, we should multiply both sides of the equation by 8 to isolate the variable x.

x = -8

Therefore, the correct answer is x = -8.

If we want to check our answer, we can plug -8 back into the original equation.

-8/8 - 2 = -3

-1 -2 = -3

-3 = -3

Since the two sides match, we know that we got the correct answer.

Hope this helps!

Please help me with the simplifying
aliya0001 [1]

The key here is to not worry too much and just follow PEMDAS.

Here we have the expression (5\cdot 7)^2.  Following PEMDAS, we complete the expression inside the parentheses first, or 5\cdot 7 = 35. This gives us (35)^2 or just 35^2.

Hope this helps.

Ryan starts saving money to buy a car right after his 16th birthday. He already has $120 from his birthday. After 3 months he ha
nlexa [21]

Remark

The basic equation is y = mx + b

y = the total amount of money

m = The amount of money he save each month (it is a constant).

b = the y intercept which is his starting amount or 120 dollars.

x = the number of months (this is a variable).

After 3 months he has 840 dollars. That's y

840 = 3*m + 120    Subtract 120  from both sides

840 - 120 = 3m

720 = 3m

240 = m   So he saves 240 every month.

Now the equation becomes.

y = 240 * x + 120

Savings after 24 months

y = Total

m = 240 dollars/month

x = 24 months

b = 120

y = 24*240 + 120

y = 5760 + 120

y = 5580

He had 5580 dollars after saving for 2 years (or 24 months total) This assumes that when he started, he took his birthday money and added a 1 month payment to it
