An ice cream factory makes 29 quarts of ice cream in 5 hours. How many quarts could be made in 48 hours ? What was that rate per

Vadim26 [7]

We can easily get the quarts per hour rate by dividing the number of quarts by the number of hours:

$\text{29 quarts in 5 hours} \implies \dfrac{29}{5} = 5.8 \text{ quarts in 1 hour}$

Now that we have the quarts per hour rate, we can easily address the question: the factory could make

$5.8\cdot 48 = 278.4$

quarts in 48 hours, with a daily rate of

$5.8\cdot 24 = 139.2$

quarts per day

Solve the following system of equations by linear combination: 5x 2y = 14 y = x – 7

natta225 [31]

I would use subsitution
y=x-7
sub x-7 for every x
5x+2(x-7)=14
5x+2x-14=14
add 14 to both sides
7x=28
divide both sides by 7
x=4
sub
y=x-7
y=4-7
y=-3

x=4
y=-3
(4,-3)
