Answer:
9,991
Step-by-step explanation:
Red to yellow.......7:3....added = 10
so 7/10 of the total students wore red and 3/10 of the total students wore yellow
and there are 300 total students...
7/10(300) = 2100/10 = 210 wore red
3/10(300) = 900/10 = 90 wore yellow
how many more wore red.....(210 - 90) = 120 more students wore red then yellow
Answer:
x = -3
Step-by-step explanation:
1+3x=-2(x+7)
Distribute
1+3x = -2x-14
Add 2x to each side
1+3x+2x = -2x+2x-14
1+5x = -14
Subtract 1 from each side
1-1+5x= -14-1
5x = -15
Divide each side by 5
5x/5 = -15/5
x = -3
