Micaela is 2 years older than sam. in 4 years, the sum of their ages will be 40. how old is micaela now? describe and fix any errors in the solution. let m = micaela’s age and s = sam’s age. m = s + 2 (s + 4) + (s + 2 + 4) = 40 s = 15 sam is 15.

Micaela is 17

Step-by-step explanation:

s+2=m

(s+2+4)+(s+4)=40

(s+6)+(s+4)=40

2s+10=40

40-10=30

2s=30

30/2= 15

s=15

{s+2=m}

15+2=m

m=17

Sample The equation and its solution are correct.

The question asked was not answered. The question asks for Micaela’s age, not Sam’s.

Micaela is 17 years old.

It is important to include the label of years in the answer.

Step-by-step explanation:For sure

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
