Which expression is equivalent to 73⋅ 7−5?

Answer:

13(3 - z) = 13(3 - z)

13(3 - z) = 39 - 13z

Step-by-step explanation:

To make the equation have infinitely many solutions, when you simplify, the equation will become z = z

To make this happen, the equation has to be the same on either side of the equal sign. Here are the two options :

13(3 - z) = 13(3 - z)

13(3 - z) = 39 - 13z

Answer:

5[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex] , then

[tex]\sqrt{75}[/tex]

= [tex]\sqrt{25(3)}[/tex]

= [tex]\sqrt{25}[/tex] × [tex]\sqrt{3}[/tex] = 5[tex]\sqrt{3}[/tex]

Answer:

the answer is -2

Step-by-step explanation:

LOGIC lol

i’ll try to break it down for u so u can understand a little better.

the horizontal line is X and the vertical line is Y.

if u start in the middle going horizontally to the right u can find X and X will = 2

to find Y u need to start in the middle and count upwards until you find where the lines meet to create a point. Y = 1

X/Y = 2/1 which can simplify to 2

But since the line is going from left to right and going downwards it is negative hope this helped :)

Answer:

I think it's 6

Dhdneoemd

Answer:

6

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] of 12 = [tex]\frac{12}{3}[/tex] = 4

let the number required be n , then

[tex]\frac{2}{3}[/tex] n = 4 ( multiply both sides by 3 to clear the fraction

2n = 12 ( divide both sides by 2 )

n = 6

Thus

[tex]\frac{1}{3}[/tex] of 12 = [tex]\frac{2}{3}[/tex] of 6

Answer:

y = -3x - 7

Step-by-step explanation:

turn into slope-intercept form:

9x + 3y = 8: subtract 9x to isolate y

3y = -9x + 8: divide by three to isolate again

y = -3x + 8/3 (line): Substitute y and x and replace 8/3 with b

-4 = -3(-1) + b: distribute

-4 = 3 +b: isolate b by subtracting 3

-7 = b

Substitute for b in original equation

y = -3x - 7

Answer:

y=-3x-7

Step-by-step explanation:

First you need to change the equation to slope intercept form. so the equation becomes y=-3x+8/3. now you change it point slope, y-y1=m(x-x1), y--4=-3(x--1), which also becomes y+4=-3(x+1), now you multiply. -3 times x and 1 which makes the equation, y+4= -3x+-3, then subtract from each side since its a positive number. so now the equation y= -3x-7

Answer:

2 miles per hours

Step-by-step explanation:

You divide 1/3 mile by 1/6 hour

Use the reciprocal.

1/3 x 6/1 = 2/1

Simplify

2/1 = 2

You can also solve it this way:

If 1/6 hour is 10 minutes, and it takes 10 minutes to walk 1/3 a mile, then it would take 30 minutes to walk a mile.

30 x 2 = 60

Either way, Richard walks 2 miles per hour.

Richard is walking at an average speed of 2 miles per hour which is the correct answer would be option (B).

Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.

To determine how fast is Richard walking, in miles per hour

We have to calculate the average speed which is the ratio of the total distance traveled by a body to the total time

Total distance traveled by Richard = 1/3 mile

The total time taken = 1/6 hour

Average speed = the total distance / the total time

Average speed = (1/3) / (1/6)

Reciprocal the denominator term, and we get

Average speed = (1/3) × 6

Average speed = 2 miles per hour

Therefore, he is at an average speed of 2 miles per hour

Answer:

<2 ≅<4 with reason of vertical angle theorem.

Step-by-step explanation:

The vertical angle theorem states that two opposite (non-adjacent) angles formed by 2 intersecting lines have equal measure. In this problem, we are given that the angles are vertical angles. So the statement is that <2 ≅<4 with reason of vertical angle theorem.

Answer: this is how you do it

Step-by-step explanation:

For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.

Answer:

See below.

[tex] \sqrt{43} - \pi = 6.5574 - 3.1416 = 3.4158 [/tex]

Plot the number between 3.4 and 3.5, but much closer to 3.4 than to 3.5 since it is approximately 3.42.

(7.3 * 10^6) / (3.2 * 10^4) = 7.3/3.2 * 10^6/10^4 = 2.3 * 10^2

Next , solve as you would solve any two -step inequality. Since 2 is added to , you can get by itself on one side of the inequality by subtracting 2 from both sides. Then, to get by itself on one side of the inequality, you need to multiply both sides by 2.D

Answer:

x = 2

z = 93°

Step-by-step explanation:

set the top and bottom equations equal to each other...

5x + 77 = 9x + 69, solve for x...

subtract 69 and 5x from both sides...

8 = 4x

divide both sides by 4...

x = 2

substitute 2 for x in either equation...

5(2) + 77 = 87°

subtract 87 from 180...

180° - 87° = 93°

z = 93°

Answer:

12xy₁₁x₃

Step-by-step explanation:

Answer:

Step-by-step explanation:

P = 4x(x - 3) + 4y(y - 3) + 8xy

  = 4x² - 12x + 4y² - 12y + 8xy

  = (4x² + 8xy + 4y²) - (12x + 12y)

 = 4(x² + 2xy + y²) - 12(x + y)

 = 4(x + y)² - 12(x + y)

x+y =2 ⇒ P = 4.2² - 12.2 = 16 - 24 = -8

Answer: B is the only true statement.

Step-by-step explanation:

Answer:

It will take Rosa 5 and a half (5.5) weeks to have the same amount of money in both accounts.

Step-by-step explanation:

For this problem, we will have to set two expressions equal to each other. The first expression will represent Rosa's saving account, which already has $117 in it. Every week ([tex]x[/tex]), she adds $21 to her savings account:

[tex]21x+117[/tex]

The second expression will represent Rosa's checking account. Rosa's checking account already has $95 in it. Every week ([tex]x[/tex]), she adds $25 to her checking account:

[tex]25x+95[/tex]

Now that we have our two expressions, set them equal to each other. This is our equation that will be used to find the number of weeks ([tex]x[/tex]) it takes until Rosha has the same amount of money in both accounts:

[tex]21x+117=25x+95[/tex]

Subtract [tex]21x[/tex] from both sides of the equation:

[tex]117=4x+95[/tex]

Subtract [tex]95[/tex] from both sides of the equation:

[tex]22=4x[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]4[/tex]:

[tex]5.5=x[/tex]

[tex]x=5.5[/tex]

So it will take five and a half weeks for her accounts to have the same amount of money.

_

Check your work by substituting [tex]5.5[/tex] into the initial equation:

[tex]21(5.5)+117=25(5.5)+95[/tex]

[tex]115.5+117=137.5+95[/tex]

[tex]232.5=232.5[/tex]

Since the accounts have the same amount, the answer is correct!

Step-by-step explanation:

If number of weeks is x, then required equation is

Answer:

So, cost of 1 pair of shorts =$12

Step-by-step explanation:

Let cost of 1 pair of jeans =x

Cost 1pair of shorts =y

cost of 1 pair of shirts=z

We can set up equations as

x+4 y+2 z=84

2 x+1 y+3 z=76

x+2 y+z=52

Solve the equations for y.

Take first and second equations multiply first equation by -2 and add it with second equation.

-2 x-8 y-4 z=-168

2 x+1 y+3 z=76

Add them, it gives -7 y-z =-92

Now, take second and third equations, multiply the third equation by -2 then add them together.

2 x +1 y +3 z =76

-2 x-4 y-2 z=-104

Add them together,

-3 y +z =-28

Now, take the -7 y -z =-92 and -3 y +z =-28

Add the equations

-10 y = -120

Divide both sides by -10

y =12.

So, cost of 1 pair of shorts =$12

z=8
