Which equation represents the sentence, "Three times the number m plus twice the quantity n plus 5 is equal to 20"?

A. 3m + 2n – 5 = 20
B. 3m + 2(n + 5) = 20
C. 3m + 2(n – 5) = 20
D. 3m(2n + 5) = 20

Respuesta :

Answer: Option 'D' is correct.

Explanation:

Since we have given that

"Three times the number m plus twice the quantity n plus 5 is equal to 20"

So, Equation becomes

[tex]3m+2(n+5)=20[/tex]

As it is said that

three times the number m i.e.

[tex]3m[/tex]

twice the quantity n plus 5 i.e.

[tex]2(n+5)[/tex]

Plus both the quantity i.e.

[tex]3m+2(n+5)[/tex]

and make them equal to 20 i.e.

[tex]3m+2(n+5)=20[/tex]

Hence, Option 'D' is correct.

Answer:  B, 3m + 2(n + 5) = 20. (I've done the test)

A, C, and D aren't it because it says 3 times the number m (3m) plus n plus 5 to the second power 2(n + 5), equals 20, and B is the only one that represents the equation.
