33/60 in simplest form is 11/20.
350 grams of magic steel and 350 grams of dragon alloy #33 is needed to make 700 grams of Dragon alloy #18.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of magic steel and y represent the amount of alloy #33, hence:
(0 * x) + (y * 0.28) = 700(1 - 0.86) (1)
Also:
x + (1 - 0.28)y = 0.86(700) (2)
From both equations:
x = 350, y = 350
350 grams of magic steel and 350 grams of dragon alloy #33 is needed to make 700 grams of Dragon alloy #18.

Answer:
x = -6
Step-by-step explanation:
3x-6+4=-20
Combine like terms
3x -2 = -20
Add 2 to each side
3x-2+2 = -20 +2
3x = -18
Divide each side by 3
3x/3 = -18/3
x = -6
Answer: s = 0.9 r
Step-by-step explanation:
Since 10% is given off , then the remaining 90% is the sales price.
that is
s = 90/100 X r
s = 0.9r
Roger: $24
Bethan: $36
Explanation:
4/5 of $75 is $60
So $60 is distributed to Roger and Bethan in the ratio 2 : 3.
Add the numbers in the ratio 2 : 3
2 + 3 = 5
Divide $60 by 5
60 ÷ 5 = 12
Multiply each number in the ratio 2 : 3 by 12:
2 • 12 : 3 • 12
= 24 : 36
