Answer: x = 60

Step-by-step explanation:

Your goal is to get "x" on one side alone

110x +2400 = 100x +3000​ *what you do on one side you do to the other

       -2400               -2400

110x = 100x + 600

-100   -100

10x =600 *divide both sides by 10

x = 60

c)

M(t)=0

-2t^2+14t=0

t^2-7t=0

t(t-7)=0

t=0, 7

8.

a)

h(t)=0

-6t^2+12t+48=0

t^2-2t-8=0

(t-4)(t+2)=0

t=-2, 4

t=4

b)

h(t)=-6t^2+12t+48

h’(t)=-12t+12

h’(t)=0

-12t+12=0

12t=12

t=1

c) h(1)=54
