"of" means multiply and "is" means equal
1. x = 14
x = 14(3) <em>multiply both sides by 3 to isolate "x"</em>
x = 42
2. x = 14
x = 14(5) <em>multiply both sides by 5 to isolate "x"</em>
x = 70
3. x = 14
2x = 14(5) <em>multiply both sides by 5 </em>
2x = 70
x = 35 <em>divide both sides by 2 to isolate "x"</em>
4. x = 14
7x = 14(8) <em>multiply both sides by 8 </em>
7x = 112
x = 16 <em>divide both sides by 7 to isolate "x"</em>
Answers: 42, 70, 35, 16
3.25 * 7.8 = 25.35
10^3 * 10^6 = 10^(3+6) = 10^9
so we have 25.35 * 10^9 but in scientific notation the first number mus be <10
so the answer is 2.535 * 10^10
Given:
8000 homes
color flyers : $0.08 each
black and white flyers : $0.05 each
budget of $500
c + b = 8,000
0.08c + 0.05b = 500
c = 8,000 - b
0.08(8,000 - b) + 0.05b = 500
640 - 0.08b + 0.05b = 500
-0.03b = 500 - 640
-0.03b = -140
b = -140 / -0.03
b = 4,667 black and white flyers
c = 8,000 - b
c = 8,000 - 4,667
c = 3,333 colored flyers
0.08(c) + 0.05(b) = 500
0.08(3,333) + 0.05(4,667) = 500
266.64 + 233.35 = 500
499.99 = 500
500 = 500
There are 20 teams, so all we have to do is share those 260 players between all 20 of the teams equally, and we can do that by dividing 260 by 20.
Therefore, 260/20 = 13
So, there are 13 players on each basketball team.
