Answer:

6x-10

Step-by-step explanation:

Because if you take 9x+6 minus 3x-4 you get 6x-10 because when you subtract a negetive you add them. :) Hope this helps.

Now,

we know that,

V=Distance÷time

=49÷3.5

=14

so that,

Answer:

b=8

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2+b^2 =c^2  where a and b are the legs and c is the hypotenuse

6^2 + b^2 = 10^2

36+b^2 = 100

Subtract 36 from each side

b^2 = 100-36

b^2 = 64

Take the square root of each side

sqrt(b^2) = sqrt(64)

b = 8

Answer:

y = -1/2x - 2

Step-by-step explanation:

Slope Intercept form: y=mx+b

You need to find the slope and y-intercept.

(0,-2) is the y-intercept which is the point on the y-axis that is intersected by the linear equation which is our slope line.

Now, we need to find our slope.

*This line is a negative slope*

Starting at our y-intercept [ (0,-2) ] we need to go to a point where the line intersects.

The red dot on the coordinate plane clearly represents it.

(2,-3) is the red point in which we need to go down 1 and over 2 to get there.

So our slope should be -1 / 2

Lastly, write in slope-intercept form:
y = -1/2x - 2

Answer:

24

Step-by-step explanation:

If one of the side is 6 in and the shape is a square. All the sides most be 6 aswell. so it's 6x4

Answer:

Take the measurement of every side and add them together. This will give you the total perimeter. For example, if you have a rectangle with the measurements 4 ft on the 2 short sides and 8 ft on the two long sides, you add together 4 + 4 + 8 + 8 which equals 24.

Hope I was able to help :)

Answer:

31/55 * 111

Step-by-step explanation:

For all the other products, the number before the slash is greater than, or equal to the number after the slash. This means that the fraction is greater than or equal to 1 and thus a bigger product. For 31/55 however, the value is less than 1 (0.56) and thus, the actual product will be less than 111.

Answer:

x = 52 due to vertical angle theorem

Step-by-step explanation:

Vertical angles mean that the angles are congruent.

If we know that one angle is 52 the other one shall be 52 as well because vertical angles state that ones that are directly across are congruent known as equal.

Answer:

33

Step-by-step explanation:

From what we know in April and May combined Joe has collected 61 stamps (27+34=61). To then work out how many Joe collected in June you would take the 61 we know he has already got away from the grand total of 94 (94-61=33) this means in June he collects 33 stamps. Hope this helps :)

Correct choice is C.

Answer:

x < 1939

Step-by-step explanation:

If we want years before 1939, then x must be less than 1939. From this we can make the inequality: x < 1939. It shows that x must be anything less than 1939.

1 foot = 12 inches = 1/12

21/1 x 1/12 = 21/12 = 1.75 feet

Answer: 1.75 feet

to get the equation of any straight line, we simply need two points off of it, let's use the points in the picture below.

[tex](\stackrel{x_1}{-2}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-1}-\stackrel{y1}{2}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{(-2)}}}\implies \cfrac{-3}{4+2}\implies \cfrac{-3}{6}\implies -\cfrac{1}{2}[/tex]

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{2}=\stackrel{m}{-\cfrac{1}{2}}(x-\stackrel{x_1}{(-2)}) \\\\\\ y-2 = -\cfrac{1}{2}(x+2)\implies y-2=-\cfrac{1}{2}x-1\implies y=-\cfrac{1}{2}x+1[/tex]

Answer:

I took the Test it is 72

Using the z-distribution, it is found that the smallest sample size required is given by:

B) 7 vehicles.

It is given by:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

In this problem, we have a 90% confidence level, hence[tex]\alpha = 0.9[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.9}{2} = 0.95[/tex], so the critical value is z = 1.645.

The margin of error and the population standard deviation are given by, respectively:

[tex]M = 10, \sigma = 15[/tex].

Then, we solve for n to find the needed sample size.

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]10 = 1.645\frac{15}{\sqrt{n}}[/tex]

[tex]10\sqrt{n} = 1.645 \times 15[/tex]

[tex]\sqrt{n} = 1.645 \times 1.5[/tex]

[tex](\sqrt{n})^2 = (1.645 \times 1.5)^2[/tex]

[tex]n = 6.1[/tex]

Rounding up, 7 vehicles have to be sampled, hence option B is correct.

Answer:

y = -5x + 12

Step-by-step explanation:

First remember the equation y = mx + b

We have values for x, y, and m so all we need to do is solve for b.

2 = -5 (2) + b

2 = -10 + b

12 = b

Then plug that value back in and keep the variables for x and y

y = -5x + 12

Step-by-step explanation:

Answer: 4x-15y+15

Step-by-step explanation:

Just combine then simplify.

PLEASE MARK ME THE BRAINLIEST!!!

Answer:

4x - 15y + 15

Step-by-step explanation:

You can only combine terms that have the same variable. For example, a number with the "x" variable can only be added to/subtracted by other numbers with the "x" variable. To make the simplifying easier, I would start by putting these terms next to each other. Remember that the negative values must stay with the value they are next to (i.e., the (-) in front of the (7y) must stay with it).

Starting: -2x + 3 - 8y + 12 + 6x - 7y

Rearranged: -2x + 6x - 8y - 7y + 3 + 12

Then, combine the values by adding them. Remember, adding a negative value means you end up subtracting it.

(-2x) and (6x) combine to form (4x)

(-8y) and (-7y) combine to form (-15y)

(3) and (12) combine to form (15)

This leaves you with:  4x - 15y + 15

Answer:

x would be equal to 1.1

Step-by-step explanation:

Step 1:  Determine the value of x

I assume that the equation looks like this:  16/x = 45/3

Therefore, using the cross multiply method we can do (16*3) = (x*45)

This will give us 48 = 45x

Then we divide both sides by 45 so we can isolate x by itself

45x/45 = 48/45

x = 1.0667

Then we round to the nearest tenth

x = 1.0667

x = 1.1

Answer: x would be equal to 1.1

Answer:

x = 16/15, or (to the nearest tenth) x = 1.1

Step-by-step explanation:

Note:  there must be an " = " sign between the two fractions:

 16         45

------- = -------

   x           3

Also note that 45/3 reduces to 15:      16/x = 15

Multiplying both sides by x yields 16 = 15x, so that x must be  x = 16/15 = 1.1

Answer:

Mila

Step-by-step explanation:

3+2=5

60/5=12

12*3=36

Mila uses 36 orange beads

7+5=12

60/12=5

7*5=35

Ben uses 35 orange beads

Mila uses more beads

hope this helps you on your homework :D

Answer:

From the results we can see that Mila would be using 15 orange beads.

Step-by-step explanation:

Step 1:  Determine a common denominator

We need to figure out a ratio between the two people in a way so we can compare the amount of orange beads that are being used.  We know that Mila uses 2 red beads while ben uses 5 red beads which means that we can use a ratio of 10.

(2 red beads * 5) : (3 orange beads * 5)

(10 red beads) : (15 orange beads)

(5 red beads * 2) : (7 orange beads * 2)

(10 red beads) : (14 orange beads)

Answer: From the results we can see that Mila would be using 15 orange beads.
