Answer:
Step-by-step explanation:
The Weight of Ingredients to be used by Chef Selena are:
pounds of pasta, - 6 pounds of sauce; and
pounds of onions.
Total Weight of Food Made, x
Since each serving is 
Number of Servings of her dish, y
The two equations needed to solve the problem are therefore:
Let's call the three numbers x, y, and z.
The numbers are 3, 12, and 5.
x + y + z = 20
y = 4x
x + z = 8
We can rewrite the first equation because y is 4x, so
x + 4x + z = 20
5x + z = 20
And now we can use simultaneous equation rules to solve
5x + z = 20
x + z = 8
5x + z = 20
5x + 5z = 40
(subtract)
-4z + -20
÷ -4
z = 5
x + z = 8
x + 5 = 8
x = 3
y = 4x
y = 4 × 3
y = 12
I hope this helps!
6 1/4 :) Is this correct?
Answer:
See Below (Isolate the variables)
Step-by-step explanation:
13) d = 4AM solve for M
Divide both sides by 4A
14) 
= f+h solve for A
Multiply both sides by 6
A = 6( f+h)
15) h - m = qb solve for H
Add m to both sides
h - m = qb
+ m +m
h = qb + m
Answer:
four bouquets
Step-by-step explanation:
The way of solving this problem is tell Abigail to keep the relation between flowers constant, that is
We have 16 roses and 20 carnations
16 2 16 = 2⁴ 20 2 20 = 2² * 5
8 2 10 2
4 2 5 5
2 2 1
1
So we will make bouquets of 4 roses and 5 carnations
so we will have 4 bouquets using all flowers
