Using a system of equations, it is found that Ajay is 25 years old today.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Wale was twice as old as Ajay 10 years back, hence:
Wale will be 40 years old in 10 years, hence:
Then, Ajay's present age is found as follows.

Answer:
$3100
Step-by-step explanation:
Step one:
given data
Principal = $2500
rate = 1.2%
time = 20 years
Step two:
The simple interest is expressed as
SI= PRT/100
substitute
SI= 2500*1.2*20/100
SI= $600
The account balance after 20 years is
= principal + Simple interest
= 2500+600
= $3100
Answer:
Step-by-step explanation:
12x+36 =8x+36+4x
12x+36= 12x+36
which means any value of x will work.
Okay, this is C. This is because since he has already driven 3.5miles so far, we already have that and we add it cause we have already driven that. Then, it says 100 miles for every TWO hours. For x, we need to find how many miles we drive in ONE hour. So: 100/2 miles = 2/2 hours: 50 miles = 1 hr.
<h2>-1/6 x -3/5 = 3/30 =<em><u>
1/10</u></em></h2>
