Answer:
A
Step-by-step explanation:
3+7 is 10, not 11. Therefore, x cannot be 3.
The equation to answer this question would be t divided by m
2.33 years. The principal amount of 40,000 takes 2.33 years to reach 51,200 with a simple interest of 0.12. 2.33 years.
Answer:
At this point just choose a mean thats half of the value
Answer:
Jason has $58.20 and Jeff has $13.80.
Step-by-step explanation:
Let x represent the amount of money Jason has, and y represent the amount of money Jeff has.
We know that together they have $72. So, we can write the following equation:

We know that Jason has three <em>more</em> than four <em>times</em> the amount of money Jeff has. So:

This is a system of equations. We can solve it by using substitution. Let's substitute the second equation into the first. This yields:

Combine like terms:

Subtract 3 from both sides:

Divide both sides by 5:

So, Jeff has $13.80
We know that Jason has three more than four times the amount of money Jeff has.
Therefore, Jason has:

Multiply and add:

So, Jason has $58.20 and Jeff has $13.80.
And we're done!
