<span>4x – 20 = 900
4x = 900+20
4x = 920
x = 920/4
x = 230
he earned $230

At the end of each year, the amount is (1 + 11%) = 1.11 times the amount at the beginning of the year. When that multiplier is applied 5 times, the result is
$30 * 1.11^5 ≈ $50.55
Ron should receive $7.98. Jerry and Steve each worked for 4 hours, while Ron was one hour late, so he worked for 3 hours. Together, they worked for 4*2+3=11 hours, receiving $29.25 in total. Each hour should be paid 29.25/11=2.66 dollars. Ron worked for three hours, so he should receive 3*2.66=7.98 dollars.
15.6 - 11.7 = 3.9
3.9 ÷ 15.6 = .25

is the study of algebraic equations on graphs
An example of the coordinate geometry is plotting point,lines and curves on
an x & Y axis thanks
