Answer:
13 31/40
Step-by-step explanation:
1) convert both fractions into improper fractions (you can do so by multiplying the whole number by the denominator/bottom part and then adding that to the numerator/top part)
by doing this, you will get 51/8 and 37/5
2) since you need a common denominator in order to add the two fractions, multiply the top and bottom of 51/8 by 5. Then, multiply the top and bottom of 37/5 by 8.
3) Then, add the top numbers together and your answer will be 551/40, which can be simplified into 13 31/40

Answer:
x=13
Step-by-step explanation:
2x+9=35
2x=35-9
2x=26
x=26/2
x=13
You need to equate the two expressions to get the value of x. That is 3x - 5 = x + 3 and solve for x, you will get x = 4. Then get the length of line ZB and line BA by substituting the value of x you've got; hence line ZB = 3(4) - 5 = 7 and line BA = 4 + 3 = 7. Add the two lines to form a single line ZA, that is 7 + 7 = 14. So the answer is D.14
