Consider the following system of equations.

3x + 5y = 18
6x − 5y = 20

Decide which procedures eliminate the x variable and which eliminate the y variable. Drag and drop each procedure that will eliminate one of the variables into the appropriate category.

Subtract the second equation from the first equation.
Add the first and second equations. Multiply the first equation by −2; then add the two equations.
Divide the second equation by −2; then add the two equations. Subtract the first equation from the second equation.
Multiply the first equation by 2 then add the two equations.
Eliminate x Eliminate y

Answers

Answer:

Option B

On adding the first and second equations y can be eliminated

Step-by-step explanation:

The two equations are as follows

3x + 5y = 18 -- Eq (1)

6x − 5y = 20 -- Eq (2)

Adding equation 1 and 2, we get -

3x + 6x + 5y -5y = 18

9x = 18

x = 2

y = (18-3*2)/5

y = 12/5 = 2.4

Fernanda is filling a cylindrical pot with cans of vegetable soup. The pot has a diameter of 15 in. and a height of 11 in. The soup can has a diameter of 3 in. and a height of 6 in. How many cans of soup will it take to fill the pot? Round to the nearest can.

Answers

Answer:

45 cans

Step-by-step explanation:

To find the volume of a cylinder, we need to find the area of the cross section, which in this case is π(radius)², and multiply it with the height of the cylinder

This means the pot has a volume of:

- pot has radius of 7.5in. as diameter is 2 x radius

π x (15/2)² x 11 = 618.75π in.³

The soup can has a volume of:

- soup can has radius of 1.5in. as diameter is 2 x radius

π x (3/2))² x 6 = 13.5π in.³

Divide the volume of the pot by the volume of the can to get how many cans of soup will it take to fill the pot:

618.75π in.³ ÷ 13.5π in.³ = 45.833... cans

The question states you need to round to nearest can which would be 45 cans, but personally, I thought you would always round up as 45 cans won't fill up the whole pot, but it's up to the question.

find sin x/2 given that sin x=1/4 and 0

Answers

Answer:

Step-by-step explanation:

find sin x/2 in radians, given that sinx =1/4 and x terminates in 0 less than x less than pi/2

✓ sinx=1/4=opp side/hypotenuse adj side=√(4^2-1^2)=√(16-1)=√15 cosx=√15/4 sin x/2=√[(1-cosx)/2]=√[(1-√15/4)/2] .. calculator check: sinx=(1/4

The value of sin x/2 for sin x=1/4 and 0 is 0.124 and 0 respectively.

Given that, sin x=1/4 and 0.

We need to find sin x/2.

How to find the value of sin?

The sin formula is given as sin θ = Perpendicular / Hypotenuse.

Now, for sin x=1/4

sin 1/4/2=sin 1/8=0.124

=0.124

For sinx=0

sin 0/2=0

Hence, the value of sin x/2 for sin x=1/4 and 0 is 0.124 and 0 respectively.

Step-by-step explanation:

Write a rule to describe the transition of a point from (-3,3) to (-2,2)

In the answers, we see that the rule must be formatted as:

(x,y) ⇾ (x _ 1, y _ 1)

Soo . .  we take the first x (-3) and the second x (-2) and try the 2 methods:

-3 - 1 = -4

-3 +1 = -2

So we see that the first one has to + 1

Here's the rule so far.

(x,y) ⇾ (x + 1, y _ 1)

Next, take the first y (3) and the second y (2) and repeat the 2 methods:

3 + 1 = 4

3 - 1 = 2

Here we get that we have to - 1

Therefore, the rule to describe the transition of a point from (-3,3) to (-2,2) is:

(x,y) ⇾ (x + 1, y - 1)

Which is option 4 or D.

Step-by-step explanation:

The Mean is found by adding all of the values together

Then dividing it by how many values there are.

In this instance, all the values added up equal 576

576 now will be divided by how many temperatures are recorded.

576/7=82.286

A square photograph has a side length of x + 8. It is
surrounded by a frame that is 2 inches wide all the way
around. Write a simplified expression for the area of
just the picture frame.

Answers

Answer:

(x + 10)^2

Step-by-step explanation:

*It helps to draw a diagram for these types of questions

Side length of photograph: x + 8

Width of frame: 2 in.

Area of a square: s^2

A = ((x + 8) + 2)^2

= (x + 10)^2

Therefore the area of the photograph with the frame is (x + 10)^2

Answer:

8(x + 10) or 8x + 80

Step-by-step explanation:

Area of the picture:

(x + 8)²

Side of the photograph with the frame:

(x + 8) + 2*2 = x + 12

Area of the frame:

(x + 12)² - (x + 8)² = (x + 12 + x + 8)(x + 12 - x - 8) = (2x + 20)(4) = 8(x + 10)

or

8x + 80

find the circumference of the pizza use 3.14 the pizza is 7 inches

Answers

Answer:

45 inches

Step-by-step explanation:

C = (pi)(diameter).

Assuming that the radius of the pizza in this case is 7 inches, the diameter is twice that, or 14 inches.

Thus, the circumference of the pizza is C = (3.14)(14 inches) = 45 inches

approximately.

21.99

Formula: C=2 pi r
First, turn the diameter to a radius by dividing 7 inches, the diameter, by 2. This turns out to be 3.5 inches.
Then, multiply 3.5 by pi(3.14), which would give you 10.99 inches.
Last, do the last step of the formula, which is multiplying 10.99 inches by 2.
