The sum of two even consecutive integers is 114. What is the smallest integer?
Ainat [17]

Answer:

56

Step-by-step explanation:

The sum of two <em>even</em> consecutive integers is 114.

Let's let the first even integer be 2n, where n is <em>some</em> integer: it doesn't matter what n is, but if we multiply n by 2, we are certainly getting an even number. This is because any integer multiplied by 2 is even.

So, this means that the second number is 2n+2.

Their sum is 114. In other words:

(2n)+(2n+2)=114

Solve for n.

Combine like terms:

4n+2=114

Subtract 2 from both sides:

4n=112

Divide both sides by 4:

n=28

So, n is 28.

This means that the first number is 28(2) or 56.

And the second number is 58.

So, the smallest integer is 56.

And we're done!

I got an equation
liberstina [14]

Answer:

X=15

Step-by-step explanation:

Yes, you are right.

The given equation is

X+U=25

If U=10, then we substitute to obtain:

X+10=25

Subtract 10 from both sides to get:

X=25-10

Simplify to get:

X=15
