Answer:
1: 2003
2: 1425
3: 2018
Step-by-step explanation:
1: 875 = 275x + 50.
875 - 50 = 275x + 50 - 50.
825 = 275x
825 ÷ 275 = 275x ÷ 275.
x = 3
2: y = 275(5) + 50.
y = 1425
3: 5,000 = 275x + 50.
5,000 - 50 = 275x + 50 - 50.
4,950 = 275x.
4,950 ÷ 275 = 275x ÷ 275.
x = 18.
I hope this helped and if it did I would appreciate it if you marked me Brainliest Thank you and have a nice day!
Answer:
$2800
Step-by-step explanation:
6/100 x 2500 = 150
150 x 2 = 300
2500 + 300 = $2800

The <u>given</u> is important information we are given at the beginning of the proof that we will use in constructing the proof.
The "<u>prove</u>" is the statement we are trying to prove.
The <u>statements </u>are the steps we use to get from our given to what we're trying to prove.
The <u>reasons</u><span> are the theorems, conjectures, properties, and corollaries we use to justify the steps we take in the statements part.</span></span>
The metallurgist would need 46.875 lb of an alloy containing 30 % copper and 3.125 lb of an alloy containing 62 % copper to produce 50 lb of a third alloy.
<h3>How to estimate proportions of ingredients for an alloy by weighted averages</h3>
In this question we must prepare a <em>third</em> alloy by using correct quantity of two alloys with different <em>copper</em> concentrations. <em>Required</em> weights can be determined by applying concept of <em>weighted</em> average:
(32/100) · (50 lb) = (30/100) · x + (62/100) · (50 - x)
32 · 50 = 30 · x + 62 · (50 - x)
32 · 50 = 30 · x + 62 · 50 - 62 · x
32 · x = 30 · 50
x = 46.875
The metallurgist would need 46.875 lb of an alloy containing 30 % copper and 3.125 lb of an alloy containing 62 % copper to produce 50 lb of a third alloy.
