Micaela is 2 years older than Sam. In 4 years, the sum of their ages will be 40. How old is Micaela now?
Ann [662]

Answer:

The error is: The solution shows the Sam's age and the problem asked for Micaela's age.

Solution fixed: m=17

Micaela is 17 years old now.

Step-by-step explanation:

The error is: The solution shows the Sam's age and the problem asked for Micaela's age.

To fix the error, you can set up these equations based on the information given:

m=s+2  

(m+4)+(s+4)=40  

Solve for "s" from the first equation:

s=m-2

Substitute this equation into the second equation:

(m+4)+((m-2)+4)=40  

Now you need to solve for "m":

m+4+(m-2+4)=40\\m+4+m+2=40\\m+m=40-4-2\\2m=34\\m=\frac{34}{2}\\\\m=17

Micaela is 17 years old now.

Pls help i will provide picture
VashaNatasha [74]

Answer:

A. 4

Step-by-step explanation:

First, we can try the first option. 2/4 is equivalent to 6/12 when you multiply the fraction by 3 to get a common denominator. Since 6/12 is larger than 4/12, and the question has 1 answer, 4 is the only value that satisfices the statement and is the answer.
