Plugging 140 into the principal, or starting value, 3% as the interest rate, and 2 (years) for the time, we get 140*0.03*2 = 8.4, or $8.40 as our answer. Note that 3% turned into 0.03 as turning a percentage into a decimal requires us to divide the decimal by 100
You divide by 8 on both sides of the equal(=) sign to find what q is. 64\8=8. 8q/8 =canceled out. leaving you with ur answer which is q=8. hope this helped <3
The one point where the lines intersect is one solution. If both points are on the same line it is one solution. If the lines do not intersect it is no solution.
