SVETLANKA909090 [29]

Answer:

x(x+ 1 + 2) + y   x= 7 y=4   the actual difference is £56 = 26/28= 13/14. Reasons, He was under 15 but over 13 = 13/14 to be far too busy spending a set amount that cost multiples of the ticket. He spent so much and realized within his allowance he only managed to justify the amounts on snacks - this proportion and perhaps, spending inside the cinema as he was already there.

Subtract and simplify 10 - 5 1/8
asambeis [7]
10 - 5 1/8

Convert 5 1/8 into an improper fraction.

We do this by multiplying the denominator to the whole number and adding it to the numerator, and wee keep the denominator.

8 * 5 = 40 + 1 = 41/8

10 - 41/8

Convert 10 to a denominator of 8:

10 * 8 = 80
1 * 8 = 8

80/8 = 41/8

Subtract the numerators together and keep the denominator:

39/8

Convert to a mixed number:

4 7/8

Answer:

F. 5:4

Step-by-step explanation:

Solve for a and c to find the ratio of a to c:

  • 2a = 3b
  • a = 3/2(b)
  • 6b = 5c
  • c = 6/5(b)

Now, we can use the value of a and c to find the ratio of a to c:

  • (3/2(b))/(6/5(b))
  • 3b/2 × 5/6b
  • 15b/12b
  • 5/4

F. 5:4 is the correct answer
