Julio bought a total of 20 medium and large pumkins if he spent 53$ and bought 6 more large pumkins as medium pumkins how many l

aksik [14]

L = large pumpkin

m = medium pumpkin

Write a system of equations:

1) L + m = 20
2) m = L - 6
3) $3L + $2m = $53

Substitute L - 6 for m in equation 1:

L + (L - 6) = 20

Add 6 to both sides:

2L = 26
(L + L = 2L)

Divide two on both sides:

L = 13

Julie bought 13 large pumpkins.

Check (use equation 3):

$3(13) + $2(7) = 53
(m = 7 because 20 - 13 = 7)

Multiply:

$39 + $14 = $53 :)

At a particular restaurant each mozzarella stick has 90 cal in each pizza roll has 80 cal. A combination meal with the mozzarell

serious [3.7K]

Answer:

The meal consist 11 mozzarella sticks and 6 pizza rolls.

Step-by-step explanation:

We are given the following in the question:

Calories in mozzarella stick = 90

Calories in pizza roll = 80

Let x be the number of a mozzarella stick and y be the number of pizza rolls.

Total calories in meal = 1470

Thus, we can write the equation:

$90x + 80y = 1470$

There are five more mozzarella sticks than pizza roll.

Thus, we can write the equation:

$x = y + 5\\x-y = 5$

Solving the two equations, we get,

$90x+80y+80x-80y = 1470 + 400\\170x = 1870\\x = 11\\y = 11-5 = 6$

Thus, the meal consist 11 mozzarella sticks and 6 pizza rolls.

I will give brainliest

allochka39001 [22]

Answer:

1) Yes 2)No

Step-by-step explanation:

1) Yes because the two shorter lines combined are longer than the base and so those two lines are able to make a triangle.

2) No because the two lines on top will be equal to base line and so the two shorter lines will not be able to make a third angle because it will be level with the base.
