Melissa is 9 years old. How old will she be in x years?
solniwko [45]

Answer:

Taking that you didn't provide any other information about the values of x..

The only plausible answer, which probably isn't your case but still can be valid out of context is 19.

Step-by-step explanation:

"X" is 10 in Roman numbers.

9 + 10 = 19

(But I suppose that you had more details to the question that you didn't yet share :) )

OR.. the answer might be an algebraic expression..

<u><em>"9+x" years old.</em></u>

Simplify:<br> 2(5 + w) + 3(w + 2)
AlekseyPX

Answer:

16+5w

Step-by-step explanation:

2(5 + w) + 3(w + 2)

5+w evaluates to 5+w

Multiply 2 by 5+w

we multiply 2 by each term in 5+w term by term.

This is the distributive property of multiplication.

Multiply 2 and 5

1

2 × 5 = 10

Multiply 2 and w

Multiply 1 and w

The w just gets copied along.

w

2 × w = 2w

2*(5+w) evaluates to 10+2w

w+2 evaluates to w+2

Multiply 3 by w+2

we multiply 3 by each term in w+2 term by term.

This is the distributive property of multiplication.

Multiply 3 and w

Multiply 1 and w

The w just gets copied along.

w

3 × w = 3w

Multiply 3 and 2

1

3 × 2 = 6

3*(w+2) evaluates to 3w+6

To add the polynomials 10+2w and 3w+6 we try to add or combine terms in one polynomialwith any like terms in the other polynomial.

10 + 6 = 16

2w + 3w = 5w

The answer is 16+5w

2*(5+w)+3*(w+2) evaluates to 16+5w

The final answer is

16+5w

Regan cycles 78 miles in 6 hours.
Brut [27]

Answer:

12 mph

Step-by-step explanation:

First 30 miles while cycling at 15 mph. This means he spent 2 hours here.

Thus the 4 hours on the last 48 miles.

Average speed  =  distance / time

Average speed = 48 miles / 4 hours

Average speed = 12 mph

Therefore Regan's average speed is 12 mph for the last 48 miles.

Need help asap<br> 8th grade math
Firdavs [7]

Answer:

x = 0

Step-by-step explanation:

The distributive property of multiplication states that a(b - c) = a(b) - a(c). We can apply that to the given equation.

3(2 - x) = 6

3(2) - 3(x) = 6 (Apply distributive property on LHS)

6 - 3x = 6 (Simplify LHS)

6 - 6 - 3x = 6 - 6 (Subtract 6 from both sides)

-3x = 0 (Simplify both sides)

\frac{-3x}{-3} =\frac{0}{-3} (Divide both sides by -3)

x = 0 (Simplify)

Hope this helps!
