Question

Which equation can be used to represent the statement?

Sixteen is the same as one and two-tenths times a number added to negative 8.

Answer 1

Answer:

of the number is X, 16 = 1 + (2/10)×X - 8

Answer 2

Answer:

16 = $\frac{6x}{5}$ - 8

Step-by-step explanation:

Topic: One Unkown equation, mixed numbers

first we have to establish our variables, we only have one so we call

x = "a number"

and we start building our one unknown equation part by part by reading

"Sixteen is the same" means in math that "x ="

"one and two tenths"  1 $^{2/10}$

this means we have (remember how to sum fractions?)

1 + 2 / 10 = 10/10 + 2/10 = 12/10 = 6/5

so " one and two tenths times a number added to negative 8" become $\frac{6x}{5}$ + (-8)

so we have our equation

16 = $\frac{6x}{5}$  + (-8) or 16 = $\frac{6x}{5}$  - 8
