Answer:
5 cartons of eggs
3 packages of steaks
Total cost=$55
Step-by-step explanation:
Hi, to answer this question we have to find the least common multiple of
6 (number of eggs in a carton) and 10 (number of ham steaks in each package)
LCM = 30
6 12 18 24 30
10 20 30 40 50
Since each carton of eggs (x) has 6 eggs, that expression must be equal to 30(eggs) to find the number of cartons.
6 (x ) = 30
Solving for x
x = 30/6
x = 5 cartons
Same process for the steak, where y= number of packages .
10 y = 30
y = 30/10
y=3 packages
Since each carton costs $2 and each package of steaks cost $15:
Total Cost =x 2+y 15
Replacing with the values of x and y calculated
Total cost = (5)2 + (3)15 = 10+45 =$55

Answer:
x = 5
z =2
y =4.4
Step-by-step explanation:
y varies directly as x
y = kx
and inversely as z
y = kx/z
Putting in the numbers in the first line of the table, we can solve for k
13.75 = k * 25/4
Multiply by 4
13.75*4 = 25k
55 =25k
Divide by 25
55/25 = 25k/25
2.2 = k
Now we can fill in the table
y = 2.2 x/z
Row 2 we need to find x
1 = 2.2 x/11
Multiply by 11
11 = 2.2 x
Divide by 2.2
11/2.2 = 2.2x
5 =x
Row 3 we need to find z
18.7 = 2.2 *17/z
18.7 = 37.4 /z
Multiply by z
18.7z = 37.4
Divide by 18.7
18.7/18.7z = 37.4/18.8
z =2
Row 4 we need to find y
y = 2.2 *10/5
y = 22/5
y =4.4
Answer
-8/3 (fraction)
or in decimal form it would be -2.6 (the six would be repeating)
