Step-by-step explanation:

The given relations let you formulate two equations in the two unknown values. These can be solved by any of the usual methods.

__

Let x represent the caloric content of a cheeseburger, and y the caloric content of a small order of fries. The problem statement tells us ...

  2x +y = 1320

  3x +2y = 2170

__

Subtracting the second equation from twice the first gives ...

  2(2x +y) -(3x +2y) = 2(1320) -(2170)

  x = 470

Using the first equation, we can find y:

  y = 1320 -2x = 1320 -2(470) = 380

__

A cheeseburger has 470 calories; a small order of fries, 380 calories.

The number of edges of a polyhedron with 4 faces and 4 vertices will be 6.

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

Using Euler's formula, the number of the edges does a polyhedron with 4 faces and 4 vertices have

We know the formula for the edges of the polyhedron will be

F + V = E + 2

The number of faces, vertices, and edges of a polyhedron are denoted by the letters F, V, and E.

Then we have

4 + 4 = E + 2

     E = 8 - 2

     E = 6

Answer:

    43. (2) $2.00

Step-by-step explanation:

Question 43

Subtract Equation 2 from Equation 1.

Answer:

(2)  $2.00

Step-by-step explanation:

Jack's order

3 slices of cheese pizza and 4 slices of mushroom pizza = $12.50

Grace's order

3 slices of cheese pizza and 2 slices of mushroom pizza = $8.50

The difference between the two orders is 2 slices of mushroom pizza.

The difference between the cost of the two orders is:

$12.50 - $8.50 = $4.00

Therefore, 2 slices of mushroom pizza costs $4.00

So the cost of 1 slice of mushroom pizza is:

$4.00 ÷ 2 = $2.00

Answer:

D. is the correct option

Step-by-step explanation:

There is a total of 5 people, so we can either split the pizza cost into 5, or into 10 and multiply by 2 (since each guest ate 2 slices) We'll do the first option since it's simpler.

$17.49 ÷ 5 = 3.489 or rounded up to $3.50

Next, we'll add $1.19 to $3.59 which equals $4.69

The area of the pentagon, rounded to the nearest tenth will be 32.7 square cm. Then the correct option is C.

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

A regular pentagon has an apothem measuring 3 cm and a perimeter of 21.8 cm.

Then the side length of the pentagon will be

5 x Side length = 21.8 cm

     Side length = 4.36 cm

Then the area of the pentagon, rounded to the nearest tenth will be

Area of pentagon = 5 x area of triangle

Area of pentagon = 5 x 1/2 x 4.36 x 3

Area of pentagon = 32.7 square cm

Thus, the correct option is C.

There were 14 boys at Mina's disco for her birthday.

A ratio is a quantitative value that shows the number of times a certain value is in another value.

It is given that for every 2 boys at the disco, there were 3 girls. This means that the ratio of boys to girls at the disco is 2:3.

Let the proportionality constant be x.

Therefore total boys and girls are 2x and 3x respectively.

There are 35 kids at the disco. This means that the number of boys plus girls is 35. It can be written as shown below:

2x + 3x = 35

⇒ x = 35/5

⇒ x = 7

Total number of boys = 2x

= 2 * 7

= 14 boys

Therefore the total number of boys at the disco is 14.

Answer:

[tex]160[/tex] °

Step-by-step explanation:

An alternative method is to use the exterior angle.

the sum of the exterior angles is ALWAYS 360 °

So you can find the size of the exterior angles of a regular polygon quite easily:

If there are 18 sides ( n = 18 ) , then each exterior angle is:

[tex]\frac{360}{n} =\frac{360}{18} = 20[/tex]°

The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line.

∴ each interior angle is 180° - 20° = 160°

The system of equations that we need to solve is:

And the solution is x = 49 and y = 101.

Let's define the variables:

We know that the total number of CDs is 150, then:

x + y = 150

And we know that:

y = 2x + 3

Then the two equations that represent the information (and conform a system of equations) are:

x + y = 150

y = 2x + 3

b) The graphs of the two equations can be seen below.

c) To find the solution, we just need to see where the graphs intercept.

We can see that the intercept is (49, 101), this means that:

Isabella has 49 rock music CDs and 101 alternative music CDs.
