X/2 + x/5 = 5/4 show work if you can

To add x/2 and x/5 together, we note that the least common denominator between 2 and 5 is 10. Using this fact, we can turn x/2 into the equivalent fraction 5x/10, and x/5 into 2x/10. Adding the two together gets us

5x/10 + 2x/10 = 7x/10

Now, our equation reads

7x/10 = 5/4

Cross multiplying, this equation implies that

7x(4) = 10(5), or

28x = 50.

Dividing either side by 28, we find that

x = 50/28 = 25/14

To verify this, we can substitute this value in for x in the original equation to get

(25/14)/2 + (25/14)/5

For the first term, half of 1/14 is 1/28, so half of 25/14 should give us 25/28. For the second, 1/5 of 25 is 5, so 1/5 of 25/14 is appropriately 5/14, or 10/28.

25/28 + 10/28 = 35/28, and since 35 and 28 have a common factor of 7 (35 = 7 x 5, 28 = 7 x 4), we can reduce 35/28 to 5/4, showing that our answer checks out.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
