Answer: 2.5 gallons
Step-by-step explanation:
Given that:
Gallons of paint had = 6.25 gallons
Amount needed to paint room = 2/5 of the paint
Gallons of paint needed :
2/5 of 6.25
(2 * 6.25) / 5 gallons
= 12.5 / 5
= 2.5 gallons
Answer:
30
it is right
200 copies must be sold
n= number od newsletters
0,50*n+300=2,00*n
300=1,5*n
Divide both sides by 1,5
200=n
0,50*200+300=2*200
100+300=400
400=400
m=0
<em><u>mx²+2x-1=0</u></em>
if x=1/2 then
m(1/2)² +2(1/2)-1=0
m/4+1-1=0
m/4=0
