Answer:

the value of 7x-y is -14.

Step-by-step explanation:

When x=2 and y=4,

To find the value of 7x - y when x =2, y = 4, this means when ever you see x, put 2 in replacement, y, put 4 respectively.

7x - y = 7(2 - 4)

14 - 28

= -14.​

Answer:  The probability that an event will occur is the fraction of times you expect to see that event in many trials. Probabilities always range between 0 and 1. The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.

Answer:

This equation has one solution, if x = 0

Step-by-step explanation:

Because, you subtract 15 from both sides so: 9x + 15 - 15 = 3x + 15 - 15 which equals: 9x = 3x. if x = 0 this equation is true.

Answer:

X=0

Step-by-step explanation:

If we subtract 15 from both sides, then we can see 9x=3x. If x was 0, then the equation would be 9x0=3x0. Since 0 times anything equals 0, this equation would be true resulting in 0=0.

Answer:

y = 4 x 6 + 8

Step-by-step explanation:

the 4 is the amount of dogs that arent big

the is 6 is the amount that she gets for walking the normal sized dogs

the 8 dollars is the amount that she gets for walking the big dog

so you would multiply 4x6 which would give you 24
then add the 8 and you will get 32
so that would mean she gets 32$ every saturday

The probability that both marbles are blue is 9 percent.

It is given that 12 marbles in a bag, four of them are blue and the rest are green.

To find the probability that both marbles are blue.

The ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

Let both the marble be blue for event A.

P(A)=2C4/2C12     (combination formula)

=6/66

=1/11

≅0.09

=9percent.

So ,the probability that both marbles are blue is 9 percent.

Answer: 176

Step-by-step explanation:

GIven: In each stand,

It has 2 rows of 20 games.

It has 2 rows of 24 games.

Total number of video games in each stand = 2 x 20 + 2x 24

= 40+48

= 88

Since there are 2 identical stands,

then toral video games in 2 stands = 2 (88)= 176

Hence, the total number of video games Cameron's stands can hold= 176.

Answer:

[tex]\frac{5\sqrt{34}}{34}[/tex]

Step-by-step explanation:

The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = [tex]\sqrt{a^{2} + b^{2} }[/tex].

In the equation you'd write that as r = [tex]\sqrt{10^{2} + 6^{2}[/tex] which can be simplified to [tex]\sqrt{136[/tex].

You end up with [tex]\frac{10}{\sqrt{136} }[/tex] and you simplify this by doing [tex]\frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }[/tex], ending with the result of [tex]\frac{5\sqrt{34}}{\sqrt{34} }[/tex].

Answer:

[tex]\dfrac{4}{3}[/tex]

Step-by-step explanation:

Number of boxes of paper = 4

Number of printer = 3

We have to find the number of pages in each printer.

Let the number of pages in each box be 1.

Total number of pages in 4 boxes = 4

3 printer will have pages = 4

1 Printer will have pages = [tex]\dfrac{4}{3}[/tex]

Hence, pages each printer will have is equal to [tex]\dfrac{4}{3}[/tex].
