Question

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

Answer 1

Answer:

20

Step-by-step explanation:

⇔ We can set up an equation using the information given to us

$16 =1 \frac{2}{10} x+-8$

We can that 16 is equal or the same as, one and two tenths times a number which is 'x' added to negative 8

⇔ The minus cancels out the plus

$16=1\frac{2}{10} x-8$

⇔ Add 8 to both sides to isolate  $1\frac{2}{10} x$

$24 =1 \frac{2}{10} x$

⇔ Convert  $1\frac{2}{10} x$  to improper fraction to make solving easier

$24 = \frac{12}{10} x$

⇔ Multiply both sides by 10 to isolate 12x

240 = 12x

⇔ Divide both sides by 12 to isolate x

20 = x

→ The 'number' is 20

Answer 2

Answer:

20

Step-by-step explanation:

16=1 2/10R + -8

16+8= 12/10R

24=12/10R

R=20
