I'LL PICK A BRAINLIEST PERSON!!!!
A metalsmith is mixing two molten metals, each containing different percentages of silver. The table shows the amount of each molten metal used.

Which two expressions are both equivalent to t, the total number of grams in the mixture?

A. (15)(0.75) and 0.7(15 – x) + 0.9x
B. (15)(0.75) and 0.7(15 – x)(0.9x)
C. 15 + 0.75 and 0.7(15 – x) + 0.9x
D. 15 + 0.75 and 0.7(15 – x)(0.9x)

I think the answer is going to be A (15)(0.75) and 0.7(15 – x) + 0.9x, I hope this helps!! :)

Answer:

Total no. of grams in mixture is (15)(0.75) and 0.75(15-x) + 0.9x.

Step-by-step explanation:

Given,

The mass of one metal in grams is 15-x with 70% silver gives 0.7(15-x) g.

The mass of other metal in grams is x with 90% silver gives (0.09)x g.

We have to find the mixture

Given mixture 15 grams with silver content 0.7, then

Total number of grams in mixture is (15)(0.75) ad it is also equivalent to the total sum of mass of above two which gives 0.75(15-x) + 0.9x.
