jack said, “five times my age in 2 years is 100."
how old is jack now?

19 years, 7 months, and six days old

Step-by-step explanation:

100-2=98/5=19.6

18 years old

Step-by-step explanation:

Break it down: 5×(age in 2 yrs)=100

Rewrite with a variable: 5×(x+2)=100

Multiply it out: 5x + 10 = 100

Isolate the x term: 5x = 90

Isolate the x: x = 18

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
