Answer:
5
Step-by-step explanation:
2x - 3 = 7
this equation can represent the senario because the number (x) is doubles (multiplyed by 2), subtracted by 3 then equal to 7
then you can just solve for x
2x=10
x=5
Let Tina bought X number of nail polish any Y number of lip gloss.
then, X+Y=9
or,X=9-Y
Also,4.5 X+7 Y=50.5
or, 4.5 (9-Y) +7 Y=50.5
or, Y =4.........................................(i)
so, X= 9-4
= 5........................................(ii)
hence, she bought 5 nail polish and 4 lip gloss
1200 ÷ 3 = 400 is the answer
