1.) 70x/100x^2 = 7/10x
2.) 16x^3/24x = 2x^2/3
3.) 7x(2x+1)/21(2x+1) = x/3
4.) 35x - 35/x^2 - 1 = 35/x + 1
5.) x + 7/x^2 + 4x - 21 = 1/x - 3
6.) x^2 - 6x + 5 = x - 5/5
7.) x^2 - 36/x^2 - 3x - 18 = x + 6/x + 3
8.) x^2 - 3x - 10/x^2 + x - 2 = x - 5/x - 1
Answer:
6 kilometers. This is because A,B, and C are all around 18 feet. However, 6 km = 19,685 feet and that is unrealistic.
Answer:
288
Step-by-step explanation:
ok well you would set up an equation 7miles/50 mins=xmiles/75mins then you would cross multiply 7*75=50x
then you simplify 525=50x
then divide both sides by 50 and you end up with 10.5
so she would run 10.5 miles in 75 minutes
Answer:
12.5
Step-by-step explanation:
25/8 x 8/5 x 5/2 simplify 25 by 5
5/8 x 8/1 x 5/2 simplify 8 by 8
5/1 x 1/1 x 5/2
5 x 1 x 5/2
5 x 5/2
25/2
12.5
