Answer:

see explanation

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

11

5x - y + 6 = 0 ( subtract 6 from both sides )

5x - y = - 6 ← in standard form

12

y + 1 = 2(x - 3) ← distribute parenthesis

y + 1 = 2x - 6 ( subtract y from both sides )

1 = 2x - y - 6 ( add 6 to both sides )

7 = 2x - y, thus

2x - y = 7 ← in standard form

inysia [295]

Answer:

Number of trucks (y) that can be shipped if the number of cars (x) is known=\frac{21,600-3.6x}{7.5}

Step-by-step explanation:

A cargo ship can carry 21,600 Tons.

Let x denotes number of cars and y denotes number of trucks.

The cars weigh 3.6 tons each and the trucks weigh 7.5 tons each.

Therefore,

3.6x+7.5y=21,600

Now write y in terms of x.

7.5y=21,600-3.6x\\y=\frac{21,600-3.6x}{7.5}

Number of trucks (y) that can be shipped if the number of cars (x) is known=\frac{21,600-3.6x}{7.5}

Some algae contains up to 50% oil by weight. How much oil is in a 7.3-ounce sample of this type of algae?
frutty [35]

Answer: 3.65

Step-by-step explanation:

This question is asking basically what is 50% or 1/2 of 7.3.

Let's expand the number 7.3

Then, we end up getting 7.30.

We have to find 1/2 of 7.30.

\frac{1}{2} of 7.30 = 3.65

Hope this helps you!

Use euler's formula to find the missing number <br><br>vertices: 11<br>edges: 34<br>Faces: ?
larisa [96]

Answer:

F = 25

Step-by-step explanation:

Euler's formula for polyhedra states that

F + V - E = 2

Here V = 11, E = 34, thus

F + 11 - 34 = 2

F - 23 = 2  ( add 23 to both sides )

F = 25
