Expand the factored expression (multiply all the terms back together), and see if it matches up with the original expression.
Answer:
x=1/3
Step-by-step explanation:
2x-3=2(x+4)/2
*2 *2
4x-6=2(x+4)
4x-6=2x+8
6x=2
x=1/3
Answer:
10
Step-by-step explanation:
20/5 = 4 customers bought plants on Saturday; 30/5 = 6 customers bought plants on Sunday. In all 4 + 6 = 10 customers bought the plants.
The parametric segment between F and H is
P(t) = (1-t)F + tH
P(0)=F, P(1)=H.
We want P such that FP:PH=5:2
That corresponds to
