Answer:
You are drawing a right triangle. So draw the two lines off of the right angle. Then write 5 along one line. That line is now BC, so you can start naming points and putting in lengths. Then, draw the hypotenuse (AB) going from the end of the line you were writing next to, to the other line. Make sure it is at least twice as long, because it is 13 long. Then, to find the length of the last line, square 13, and subtract 25 from it. Take that number and find it's square root. You should get 12, which is your answer.

Answer:
2 : 3
Step-by-step explanation:
You need to show the ratio using the smallest whole numbers possible.
Multiply both numbers by 3.
2/3 : 1
2/3 × 3 : 1 × 3
2 : 3
Answer:
x = 3.8
Step-by-step explanation:
The equation is (5 - x) / 2 = 2x - 7
Multiply both sides by 2:
5 - x = 4x - 14
Add 14 to both sides:
19 - x = 4x
Add x to both sides:
19 = 5x
Divide both sides by 5 to isolate x:
3.8 = x
Therefore, x = 3.8.
Answer:
2 2/5
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. First convert the first into the improper fraction -8/5. Now because when dividing fractions you keep the first on, change to multiplication and flip the second equation you have
-8/5 x -3/2=?
Now you just multiply across as you would and normal time multiplying fractions. Remember a negative divided by a negative is a positive! And not after you keep, change, flip and multiply you are left with 24/10. Which is equal to 12/5 but you wanted a mixed number so we convert it into 2 2/5
