ehidna [41]

Answer:

252 children and 395 adults

Step-by-step explanation:

Make a linear system of equations, where x represents the number of children and y represents the number of adults

x+y=648

1.50x+2.25y=1269

solve using substitution, so y=648-x,

then substitute this into the second equation, so you get 1.50x+2.25(648-x)=1269,

solve for x and you will get x equals the 252

then substitute this into the first equation, so you get 252+y=648

solve and you will get y=395

Which expressions are equivalent to 12 - 14/3m + 2/3m ?

yawa3891 [41]

ANSWER

The correct answers are option B and D.

$12 - 4m$

EXPLANATION

The given expression is

$12 - \frac{14}{3} m + \frac{2}{3}m$

We need to simplify the above expression in order to determine the option that is equivalent to it.

The least common denominator for the last two fractions is 3.

This implies that,

$= 12 + \frac{ - 14m + 2m}{3}$
We simplify to obtain,

$= 12 + \frac{ - 12m}{3}$

This further simplifies to give us,

$12 - 4m$

This is option B.

When we further factor -4, we get,

$-4(m-3)$

This is option D.
