The age of Sydney is 25 years old

<u>Solution:</u>

Given that Devaughn is 7 years older than Sydney

The sum of their ages is 57

Let the age of Sydney be "x"

Then according to given information,

Age of Devaughn = x + 7

Now, Sum of Sydney age and Devaughn age = 57

Substituting the values we get,

x + x + 7 = 57

2x + 7 = 57

2x = 57 - 7

2x = 50

x = 25

"x" represents age of Sydney. Hence Sydney's age is 25 years old

Answer:

g(n) = \frac{11+5n}{3}

Step-by-step explanation:

Given

3m - 5n = 11

Rearrange making m the subject

Add 5n to both sides

3m = 11 + 5n ( divide both sides by 3 )

m = \frac{11+5n}{3} , thus

m = g(n) = \frac{11+5n}{3}

Answer:

B

Step-by-step explanation:

m+4\leq6

We subtract 4 from each side to get m\leq2

Let's plug in a random point such as 0.

0+4\leq6 \\ \\ 4\leq6

Since this is true, the inequality we made is true.
