Twenty, which is 4 more than half, of the students in Bryan’s homeroom have tickets to attend the school’s musical. Choose Yes or No to tell whether each of the following equations can be used to find the number of students in Bryan’s homeroom.
4 – 1/2m = 20
1/2m + 4 = 20
1/2m – 4 = 20
4 = 20 – 1/2m

Respuesta :

[tex]4 - \frac{1}{2}m = 20[/tex]= > NO

[tex]\frac{1}{2}m +4 = 20[/tex] => YES

[tex]\frac{1}{2}m -4 = 20[/tex] => NO

[tex]4 = 20 - \frac{1}{2}m[/tex] => YES

Step-by-step explanation:

We have to convert the given statement into equation to compare with the given equations

So,

Let m be the number of students then

half of them will be 1/2m

4 more than half of students

1/2m+4

Equal to 20

so the equation is:

[tex]\frac{1}{2}m+4 = 20\\Can\ also\ be\ written\ as:\\4 = 20-\frac{1}{2}m[/tex]

So,

[tex]4 - \frac{1}{2}m = 20[/tex]= > NO

[tex]\frac{1}{2}m +4 = 20[/tex] => YES

[tex]\frac{1}{2}m -4 = 20[/tex] => NO

[tex]4 = 20 - \frac{1}{2}m[/tex] => YES
