To find percents.

First divide -----> 18/20 = 0.9

Then multiply by 100 or move decimal 2 places to the right.

----> 0.9 * 100 = 90

Replace the words with what you know
(Original cost)(6%)=5.25
(Original cost)(0.06)=5.25
(original cost)=5.25/0.06=87.5

If 3x+2=5/9, what is the value of −3x+8?<br><br>Group of answer choices

allsm [11]

Answer:

= 4

Step-by-step explanation:

first lets find the value of x in 3x+2=5/9

3x+2=5/9

3x = $\frac{5}{9}$ -2

3x = $\frac{3}{9}$

3x = $\frac{1}{2}$

x = $\frac{1}{2 * 3\\ }$

x = $\frac{1}{6}$

$\frac{1}{6}$ can also be written as $6^{-1}$

−3x+8

-3 ( $\frac{1}{6}$ ) +8

$\frac{-3}{6}$ +8

= 4

Evaluate t-u/v when t=2 u=(-8) v(-1/2)

Dovator [93]

Simple, plug n chug...

$t- \frac{u}{v}$

t=2

u=-8

v=-0.5

Now, plug in what you have,

$2- \frac{-8}{-0.5}$

$\frac{-8}{-0.5} =16$

Now,

2-16=-14

Thus, your answer, -14.
