Answer:

There are 2 chickens and 14 cows.

Equations:

2x + 4y = 60

x + y = 16

Step-by-step explanation:

2x + 2y = 32

Substituting now:

32 + 2y = 60

2y = 28

y = 14

x = 16 - 14 = 2

Answer:

y -3 = -4(x+2)

Step-by-step explanation:

The point slope form of a line is

(y-y1) = m(x-x1)

where m is the slope and (x1,y1) is a point on the line

y -3 = -4(x- -2)

y -3 = -4(x+2)

Step-by-step explanation:

Answer:

720

Step-by-step explanation:

Cherries Cherie pie

240 = 3

X = 9

The known number of cherries will be given as x then u cross multiply

3×X=240×9

3X=2,160

Divide both sides by 3

3/3X=2,160/3

X=2,160/3

X=720

This implies that the number of cherries needed to make 9 cherry pie is 720

Explanation:

The left-most point is at (-3,-2). The x coordinate is all we're concerned with here. The x coordinate for this point is x = -3. This is the smallest x value possible as an input. We cannot have x = -4 as that is nowhere on the blue curve.

So the domain is the set of real numbers x such that x is -4 or larger

In set builder notation, that would look like [tex]\{x|x\in\mathbb{R}, \ x \ge -3\}[/tex]

Step-by-step explanation:

8z+74+2z+56=180

10z+130=180

10z=50

z=5

Answer:

Step-by-step explanation:

To Find the value of x in this Alternate Interior Angle Relationship..

add [tex]8x+74[/tex] and [tex]2x+56[/tex]

[tex]8x+74+2x+56[/tex] combine like terms

[tex]10x+130=180[/tex]

subtract 130 on both sides

[tex]10x=50[/tex]

divide 10 on both sides

[tex]x=5[/tex]

Now solve for the angle of measure B

∠B=2(5)+56

∠B=10+56

∠B=66°

Answer :

By using EDL

a=bq+r

where a is > b

so a =867 and b=255

255=102×2+51

here r≠0 so a=102 and b=51

102=51×2+0

here r=0

so, Hcf of (867,255) is =51

We have,

Marcus is building a model of Earth using a sphere with a surface area of [tex]400\pi\ \text{inch}^2[/tex].

It is required to find the radius of the sphere Marcus is using for his model.

The surface area of a circular shaped object is given by :

[tex]A=\dfrac{4}{3}\pi r^3[/tex]

r is radius

[tex]r=(\dfrac{3A}{4\pi})^{1/3}\\\\r=(\dfrac{3\times 400\pi}{4\pi})^{1/3}\\\\r=6.69\ \text{inch}[/tex]

Answer:

Angle 1 = 110 degrees

Angle 2 = 70 degrees

Angle 3 = 100 degrees

Angle 4 = 80 degrees

Step-by-step explanation:

We will first of all search for the pieces of information given in the question that can help us to solve the problem.

From the diagram, we can see that angle 3 and angle 4 are already given as

Angle 3 = 100 degrees

Angle 4 = 80 degrees

The value of angle 1 has already been supplied as 110 degrees. This leaves us with angle 2 to find.

Recall that the angles in a straight line all sum up to 180 degrees. angle 1 and 2 are on the same straight line, hence angle 2 can be found by solving 180 - 110 = 70 degrees

Angle 2 = 70 degrees

Step-by-step explanation:

Reciprocal of -9/2 = -2/9

Reciprocal of 5/18 = 18/5

Multiplying both:

=> [tex]\frac{-2}{9}*\frac{18}{5}[/tex]

=> [tex]\frac{-2*2}{5}[/tex]

=> -4/5

Additive Inverse of -4/5 = 4/5

So, Adding both of them:

=> [tex]-\frac{4}{5} + \frac{4}{5}[/tex]

=> 0

Answer:

45

Step-by-step explanation:

-2/9 x 18/5 + 4/5 = 45

Answer:

Correct option: c) infinitely many solutions

Step-by-step explanation:

We have an equation with two variables, so as we have a system with less equations (just one) than variables (two), we have an infinite number of solutions.

To find some solutions, we can choose values for x and then just calculate the value of y:

x = 0:

-11y = 10 -> y = -10/11

x = 1:

3 - 11y = 10 -> y = -7/11

x = 2:

6 - 11y = 10 -> y = -4/11

And so on.

So the correct option is c): infinitely many solutions

A linear equation is something of the form:

y = a*x + b

Where the solutions are the pairs (x, y) such that the equality is true.

Here we will find that the correct option is c: infinitely many solutions.

In this case, we have the equation:

3x - 11y = 10

We can rewrite this as:

3x = 10 + 11*y

x = 10/3 + (11/3)*y

Ok, now we have one variable on each side, now let's see the number of solutions.

As you can see, we have one equation with two variables.

So if for example we take y = 0, we get:

x = 10/3 + (11/3)*0 = 10/3

So one solution is (10/3, 0)

If we take y = 1, we get:

x = 10/3 + (11/3)*1 = 22/3

Then another solution is (22/3, 1)

And as you can see, y can take any real value. So we have infinite values of y.

This also means that we have infinite values of x (as we have one value of x for each value of y). Then we will have infinite solutions for the linear equation.

The correct option is c.

The selling price of the game is (d) $111.80

The given parameters are:

Discount = 30%

Selling price = $86.00

Since the item is sold less, then the original price would be more.

So, we have:

Price = Selling price * (1 + Discount)

This gives

Price = $86.00 * (1 + 30%)

Evaluate

Price = $111.80

Hence, the selling price is (d) $111.80
