Answer:

a. x + 4y = 160

b. 160

c. 40

Step-by-step explanation:

a. We can define the variables as ...

x = number of 1/2-liter bottles

y = number of 2-liter bottles

For the total number of liters to be 80, we require

1/2x + 2y = 80

We can multiply this by 2 to eliminate the fraction.

x + 4y = 160

b. The x-intercept is 160. It is the number of 1/2-liter bottles required when no 2-liter bottles are used.

c. The y-intercept is 40. It is the number of 2-liter bottles required when no 1/2-liter bottles are used.

Alina [70]

Answer:

10 sundaes will be vanilla.

Step-by-step explanation:

Given:

Fernando is making 30 sundaes with mint, chocolate,and vanilla ice cream.

1/3 of the Sunday's are mint ice-cream.

And 1/2 of the remaining sundaes are chocolate.

The rest are vanilla.

Now, to find the number of sundaes that will be vanilla.

Fernando is making sundaes total = 30.

So, the quantity of sundaes that are mint ice-cream:

$\frac{1}{3} \ of\ 30\\\\=\frac{1}{3} \times 30\\\\=10.$

Thus, 10 sundaes are mint ice-cream.

So, the remaining sundaes are:

$30-10=20.$

Thus, the remaining sundaes are = 20.

Now, to get the quantity of chocolate sundaes of the remaining sundaes:

$\frac{1}{2} \ of\ 20\\\\=\frac{1}{2} \times 20\\\\=10.$

Hence, 10 sundaes are chocolate of the remaining 20 sundaes.

As, given the rest are vanilla.

Now, to get the vanilla sundaes we subtract the 10 chocolate ice-cream from the 20 remaining sundaes:

$20-10=10.$

Therefore, 10 sundaes will be vanilla.

arlik [135]

Answer:

EF = 9

GF = 2

Step-by-step explanation:

For EF, we want to find the distance between their c coordinates, since their y coordinates are the same. We want the distance between -4 and 5, which when you add their distance from 0, is 9.

For GF, they share the same x coordinate, so you're finding the distance between their y coordinates, which are 3 and 5. The distance between the two is 2, so the length of GF is 2.
