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:

[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:

306.94 cm

Step-by-step explanation:

The formula for volume of a cylinder is pi×r^2×h. Im assuming that you mean that the base is 6.5 cm in diameter so in this case you would plug in the values and do pi×3.25^2×9.25 and get 306.94 cm

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
i apologize if my math is wrong but i am certain this is the correct answer

Area of a Rectangle

The image shows a rectangular vegetable garden with different crops.

The rectangle has a length of L=2x+9 yards and a width of W=6x-3 yards.

The area of a rectangle is:

A = WL

[tex]A=(2x+9)(6x-3)[/tex]

Operating:

[tex]A=2x(6x)-2x(3)+9(6x)-9(3)[/tex]

[tex]A=12x^2-6x+54x-27[/tex]

Simplifying:

[tex]\boxed{A=12x^2+48x-27}[/tex]

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.

The measurements that can be used to build a right-angled triangle are

[tex]6 in, 8 in, 10 in[/tex]

The measurements that can be used to build a right-angled triangle must form a Pythagorean triple. A Pythagorean triple is a set of three numbers [tex]\{x,y,z\}[/tex] that satisfy the Pythagorean relationship

[tex]x^2+y^2=z^2[/tex]

The measurements [tex]\{5 in, 7 in, 12 in\}[/tex] do not form a triple since

[tex]5^2+7^2=74\ne12^2[/tex]

The measurements [tex]\{8 in, 12 in, 14 in\}[/tex] do not form a triple since

[tex]8^2+12^2=208\ne14^2[/tex]

The measurements [tex]\{5 in, 9 in, 11 in\}[/tex] do not form a triple since

[tex]5^2+9^2=106\ne11^2[/tex]

The measurements [tex]\{6 in, 8 in, 10 in\}[/tex] form a triple since

[tex]6^2+8^2=100=10^2[/tex]

So, the last set of measurements [tex]6 in, 8 in, 10 in[/tex] can be used to build a right-angled triangle

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].

Correct me if I'm wrong but wouldn't even 15 be right could be a lot of things

Answer:

Any number above 14.3, example:15

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.
