Answer:
Solution to system is
x = 6 and y= 4
S.set={6,4}
Step-by-step explanation:
The given equations are
x + 3y = 18 ................(i)
x + 2y=14 .................(ii)
Subtracting both equation
(x+3y)-(x+2y)=18-14
x+3y-x-2y = 4
y = 4
put the value of y in equation (i)
the equation becomes
x + 3(4) = 18
x + 12 = 18
subtracting 12 from both sides
x + 12 -12 = 18-12
x =6
Solution to system is
x = 6 and y= 4
S.set={6,4}
Answer:
a) 19 batches
b) $0.18
Step-by-step explanation:
A 4-pound bag of sugar contains 4 54 one-teaspoon servings and costs $3.49. A batch of muffins uses 1/2 cup of sugar.
1 cup = 48 teaspoons
a) How many whole batches can you make if you use as much of the sugar as possible?
1 batch = 1/2 cups of sugar = 24 teaspoons of sugar
Hence,
24 teaspoons of sugar = 1 batch
454 one-teaspoon servings = x
Cross Multiply
24 × x = 1 × 454
x = 454/24
x = 18.9166666667
Approximately to whole batches = 19 batches
b) What is the cost of sugar for each batch?
454 one-teaspoon servings and costs $3.49 = 19 batches
Hence
19 batches = $3.49
1 batch = x
x= $3.49/19
x = $0.18368421052
Approximately = $0.18
There started with 50 and it doubles so that means:
100 at the end of year 1
200 at the end of year 2
400 at the end of year 3
800 at the end of year 4
Three crates would ship 750, so best answer would be 5 crates!
