Answer:
Yes
Explanation:
10 miles in 12 days means 30 miles in 36 days
You are running about .83 (repeating decimal) miles a day, so if your goal is 25 miles in 30 days it would be .83 times 30. Which is 24.9, if you look at it with the repeating decimal you should be right on track.
I hope this helps.
Well use the distributive property
-98=4x-2(5x+13)
Now multiply 2 times 5x+13
-98=4x-10x-26
Now combine like terms
-98=-6x-26
Now get 26 on the other side by adding it to -98
-6x=-72
x=12
First, your whole number has to become a fraction. Whatever whole number you get or have to use, its denominator (the bottom number of a fraction) will always be 1. Then, you multiply across. You may have to simplify.
Ex:
2/5 x 2
2/5 x 2/1
= 4/5
Answer:
6 ounces
Step-by-step explanation:
Let x = the number of ounces of the 15% alcohol solution needed to be mixed with the 4 ounces of 20% alcohol solution to obtain the 17% alcohol solution.
After converting the percentages to their decimal equivalents, set up the necessary equation as follows:
0.15x+0.20(4) = (x+4)(0.17) Simplify and solve for x.
0.15x+0.8 = 0.17x+0.68 Subtract 0.15x from both sides.
0.8 = 0.02x+0.68 Now subtract 0.68 from both sides.
0.12 = 0.02x Finally, divide both sides by 0.02
x = 6
You need to mix 6 ounces of 15% alcohol solution with 4 ounces of 20% alcohol solution to obtain 10 (x+4)ounces of 17% alcohol solution.
