So if 40% of college students scored above 70%, then 60% of college students scored below 70%.
Our equation would be: 0.60x=120
x=120/0.60
x=12000/60
So x equal 200 students took the math test
Answer:
2nd option
Step-by-step explanation:
2 3/8-1 3/10
19/8-13/10
190/80-104/80
86/80
43/40
1 3/40
10 km because you have 1 cm left over after you make 8 km with the 5cm so you just divide 8 by 4 and get 2km then add that to the 8 to get 10.
Using <em>is/of=%/100 </em> 15 lawns is what % of 60
15 over 60 = % over 100
Cross multiple and divide and you should get 25%
That percent means that 25% of the lawns <em>are</em> mowed, so <u>75% </u><u></u> of the lawns need to be mowed

You can use the quadratic formula with it which will be easier
or simple factoring
it will be (5x-11)(7x+4)
