Answer:

A. 2 to 5

Step-by-step explanation:

x is being multiplied by 2.

y is being multiplied by 5.

Although there is an infinite amount of ratios we can use when we know the values,we don't have that right now, so we have to stick to 2 to 5, which is our answer.

The sum of two consecutive integers is 77. Find the integers.

SIZIF [17.4K]

Answer:

38 and 39

Step-by-step explanation:

Since the two integers are consecutive, then one is one larger than the other. Therefore, lets call them x and x+1. We can now set up the following equation:

x+(x+1)=77

2x+1=77

2x=76

x=38

x+1=39

We use minus (-) in power as the digit is in left side of decimal

If they are in right side then we use (+) plus sign in power.
