Answer:
<h3>she should mix 1.2 quarts of sauce with 17% sugar with 1.4 quarts of sauce with 30% sugar</h3>
Step-by-step explanation:
X= quarts of sauce # 1 ( 17% of sugar)
Y= quarts of sauce # 2( 30 % of sugar )
General Balance
EQ (1)
![Y=2.6-X\\](https://tex.z-dn.net/?f=Y%3D2.6-X%5C%5C)
SUGAR BALANCE
EQ (2)
replace Y from eq(1) into eq(2)
![0.17X+0.3(2.6-X)=0.624\\0.17X+0.78-0.3X=0.624\\-0.13X=0.624-0.780\\X=\frac{-0.156}{-0.13} \\X= 1.2\\Y=2.6-1.2=1.4](https://tex.z-dn.net/?f=0.17X%2B0.3%282.6-X%29%3D0.624%5C%5C0.17X%2B0.78-0.3X%3D0.624%5C%5C-0.13X%3D0.624-0.780%5C%5CX%3D%5Cfrac%7B-0.156%7D%7B-0.13%7D%20%5C%5CX%3D%201.2%5C%5CY%3D2.6-1.2%3D1.4)
The least common multiple of 6 and 21 is 42.
Answer: Choice B)
(y+5)+y = 6
----------------------------------------------------------------
So what we do is start with x+y = 6. We can replace the 'x' with (y+5). This replacement is possible because x = y+6; ie x and y+6 are the same. Another term for "replace" is "substitute"
This is how we're able to go from x+y = 6 to (y+5)+y = 6
Answer:
-4y - 7
Step-by-step explanation:
Combine like terms. Note that there is one term with a variable (y), and two constant terms. Combine the constant terms. Note that one positive and one negative sign will result in a negative sign:
-4 + (-3) = -4 - 3 = -7
-4y - 7 is your answer.

Yes because $18 divided by 3 bracelets makes the price per bracelet $6. $30 divided by 5 bracelets makes the price per bracelet $6. The cost per bracelet is the same so the cost to bracelet ratio is the same and both are a $6 to 1 bracelet ratio
