Answer:

The required value for x =   \frac{144}{5} =  28.8

Step-by-step explanation:

Here,the given expression is:

\frac{3}{8} x + 6 = \frac{3}{4} x -12

Now, solving for the value of x:

\frac{3}{8}x - \frac{3}{4}x = -12 - 6

or, \frac{3x - 6x}{8}  = -18

or, \frac{5x}{8}  = 18

or, x = \frac{8}{5} \times 18 = 28.8

Hence, the required value for x =   \frac{144}{5} =  28.8

In a certain​ chemical, the ratio of zinc to copper is 3 to 16. A jar of the chemical contains 736 grams of copper. How many gra
evablogger [386]

The jar has 138 grams of zinc.

<u>Solution:</u>

Given that , In a certain chemical reaction, the ratio of zinc to copper is 3 to 16.  

A jar of the chemical contains 736 grams of copper.  

We have to find how many grams of zinc does it contain

Let "n" be the grams of zinc needed for 736 grams of copper  

Now, we know that,  

16 grams of copper ⇒ 3 grams of zinc

Then, 736 grams of copper ⇒ n grams of zinc

So, by criss cross multiplication,

n \times 16 = 3 \times 736

16n = 3 x 736

16n = 2208

n = 138

Hence, the jar has 138 grams of zinc.

PLEASE NEED HELP NOW WILL GIVE BRAINLIEST<br> What is the value of B?
Tresset [83]
So all the angles of triangle add up to 180 degrees. So you add up the the two other sides and subtract 180 by the answer.

61 + 58 = 119

180 - 119 = 61

So, you’re answer would be 61 degrees. Hope that helped :)
