Answer:

To find the probability of picking two boys, we need to first know how many different ways she can pick the 7th and 8th grader.

There are 12 7th-graders and 8 8th-graders. So the total number of ways she can pick is:

12

×

8

=

96

To get two boys picked, there are 5 boys in the 7th-grade class and 4 in the 8th-grade class, so there are:

Answer:Number of small boxes shipped = 8

Number of large boxes shipped = 13

Step-by-step explanation:

Step-by-step explanation:

Let x be the number of small boxes and let y be the number of large boxes

According to the first statement, a total of 21 boxes were shipped

Equation 1 will be:

x+y=21

According to 2nd statement, the total weight was 1110 and we know the weight of one small box is 25 and large box is 70

Equation 2 will be:

25x+70y=1110

Use the substitution method for solving the equation

Putting the value of x in equation 2  

25(21-y) +70y =1110

525-25y+70y = 1110

45y = 585

Y=13

Putting the value of y in equation 1  

x+13 = 21

X = 8

Number of small boxes shipped = 8

Number of large boxes shipped = 13

Answer:

x=22

Step-by-step explanation:

From the theorem of Z angles you can find that the sum of both given angles must equal 180.

So solve: 2x-26 + 7x+8 = 180

Simplify:

9x -18 = 180

9x = 198

x = 198/9 = 22

The value of x when y = 84 is 14

From the question,

The value of y varies directly with x

That is,

y ∝ x

Introducing the constant of proportionality, k

We get,

y = kx

Also, from the question

If x = 3, then y = 18

Putting these values into the equation, we can determine the value of k

[tex]y = kx[/tex]

[tex]18 = k \times 3[/tex]

Now, divide both sides by 3

[tex]\frac{18}{3}=\frac{k \times 3}{3}[/tex]

[tex]6 = k[/tex]

∴ k = 6

Now, to determine the value of x when y = 84

We will put y = 84 and the value of k =6 into the equation

[tex]y = kx[/tex]

[tex]84 = 6 x[/tex]

Divide both sides by 6

[tex]\frac{84}{6} = \frac{6x}{6}[/tex]

[tex]14 = x[/tex]

∴ [tex]x = 14[/tex]

Hence, the value of x when y = 84 is 14

Answer:

X=1

Step-by-step explanation:

If the ordered pair of the solution is (x,5), this means that y=5

With this information, we plug in 5 for y and solve for x

4x+15=19

4x=4

C. The y-intercept is (0, 150). Diego has $150 before buying any

Step-by-step explanation:

Brainlylist

The correct statement is The y-intercept is (0, 150). Diego has $150 before buying any games.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

(0, 150) and ( 1, 112.50)

Now, slope= (112.50-150)/1

slope= -37.5

So, the equation of line is

y- 150= -37.5( x- 0)

y= -37.5x+ 150

Hence, The y-intercept is (0, 150). Diego has $150 before buying any

Answer:

x° = 107°

Step-by-step explanation:

Given that m < 107° and m < x° are alternate interior angles that do not have a common vertex on alternate sides of the transversal, then it means that they have the same measure. It also implies that their supplements will have the same measure, 73°.

Therefore, x° = 107°.

Answer:

107

Step-by-step explanation:

they r on opposite sides so they are the same.

To find the slope of a line, remember:

[tex]slope=\frac{rise}{run}[/tex].

Also, the points that you choose to use to calculate your rise and your run must meet at an exact point, not in the middle of a block. In your graphs the points are the little blue dots, so that's already been done for you and that's what we'll use to calculate the slope!

Also, recall that the rise is how many blocks the line has changed vertically (so is one point lower/higher than another point)

The run is how many blocks the line has changed horizontally (so how many blocks over is the next point)

Therefore, for #1 we can see that the point on the right is over 3 blocks (run), and it goes down 1 block (rise).

So for #1, your answer is:  [tex]slope=\frac{rise}{run}=\frac{-1}{3}[/tex] or [tex]-\frac{1}{3}[/tex]

For #2 we see that one point is higher by 3 blocks (rise) and it also goes over one block (run)

So, your answer to #2 is:  [tex]slope=\frac{rise}{run}=\frac{3}{1}=3[/tex]
