Answer:
1.60$
Step-by-step explanation:
first, we have to figure out haw many times 0.75 goes into 12
pretty sure you just want the answer to this and not me to explain the whole thing so:
if you multiply 0.75 by 16 you get 12.
16x0.10= 1.6
so her mother gave 1.60$
its in order from 2 to 3
Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a
a = 10
b = -1
c = 9
1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)
1 +/- sqrt(1 - 360) / 20
x = 1 +/- sqrt(359i) / 20
Hope this helps!
