b.

8 = 3 + 4a – 3 – 5a

c.

–2 = 2 + 5a – 2 – 6a

d.

–4a + 3a – 6 = –4

What is a possible solutions of the x> 3?

Lee has $1.75 in dimes and nickels. the number of nickels is 11 more than the number of dimes. how many of each coin does he have?

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
