Find the slope

Answer: infinite solutions

Step-by-step explanation:

(−3) (4) + (−3) (−3x) = 9x + −12

−12 + 9x = 9x + −12

9x − 12 = 9x − 12

9x − 12 − 9x = 9x − 12 − 9x

−12 = −12

−12 + 12 = −12 + 12

0 = 0

Answer: 1,200 dollars

Step-by-step explanation:

We know that the cost before the discount is 6,000.

The discount price is 80% off.

So, subtract 4,800 by 6,000 because 80% of 6,000 is 4,800.

Now, we have to add the two zeros. We get 1200.

It is the answer to the question.

Answer:

idktf

Step-by-step explanation:

Given :

Length of ramp( Hypotenuse ), l = 10 ft .

Length of base, b = 5 ft .

To Find :

How high were the porch steps.

Solution :

Let, height is h.

By Pythagoras theorem :

[tex]b^2+h^2=l^2\\\\h=\sqrt{l^2-b^2}\\\\h=\sqrt{10^2-5^2}\\\\h = \sqrt{75}\\\\h = 5\sqrt{3}\ ft[/tex]

Hence, this is the required solution.

Answer:

Option A: Madison, (1.2,-1.6) is the correct answer.

Step-by-step explanation:

Observing Madison's solution it can be seen that he has used elimination method to solve the system. If elimination method has to be used the first equation has to be multiplied by 4

[tex]4(2x-y) = 4(4)\\8x-4y = 16[/tex]

While Madison has made mistake with sign of one term in equation 1 (he has written -8x instead of 8x)

So Madison's solution is wrong.

Tyler has used the substitution method to solve the system of equations and has done it correctly (Calculated value of y in terms of x from equation 1 and substituted in equation 2)

The value of x=1.2 is correct, we have to find the value of y

So,

Putting the value of x=1.2 we get,

[tex]y=2x-4\\y = 2(1.2)-4\\y = 2.4-4\\y= -1.6[/tex]

The solution of given system of equations is (1.2,-1.6)

Hence,

Option A: Madison, (1.2,-1.6) is the correct answer.

[tex]\text{We do this because we need to perform inverse operations to find}[/tex] [tex]\text{the value of the variable.}[/tex]

Answer:

40

Step-by-step explanation:

The angles are equal to eachother so 4x-26 = 3x+14

Answer:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

4 / 15 = 0.266

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 266

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.

In this case, Rule II applies, so 4/15 (or 0.266) rounded to the nearest hundredth in decimal format is:

0.27

Step-by-step explanation:

Answer:

0.266

Answer:

A. 160 Out of 40 is 400%./// B. The answer is 25/// C.  The answer is 3905%

Step-by-step explanation:

( A )  One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 160 is 40% of =  160 X 100     = 400

                                        40

( B ) The same thing as A but the numbers are switched

       One step solution:

You can easily find the answer in one step, just multiplying the part by 100 then dividing the result by the percentage.

So, 40 is 160% of = 40 × 100      = 25

                                          160

( C ) Working out a percentage increase or decrease between two numbers is pretty simple. The resulting number (the second input) is 1602 and what we need to do first is subtract the old number, 40, from it:

1602 - 40 = 1562

Once we've done that we need to divide the result, 1562, by the original number, 40. We do this because we need to compare the difference between the new number and the original:

1562      = 39.05          

40

We now have our answer in decimal format. How do we get this into percentage format? Multiply 39.05 by 100?

39.05 x 100 = 3905%

160 is percentage of 40,  40 is 160% , number is 40% of 1602​ are 64 , 64 and 640.8 respectively.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Problem A,

40% of 160 = 160 x 40 / 100

                  = 64

Problem B,

160% of 40 = 160 x 40 / 100

                  = 64

Problem C,

40% of 1602 = 1602 x 40 / 100

                     = 640.8

Therefore, 160 is percentage of 40,  40 is 160% , number is 40% of 1602​ are 64 , 64 and 640.8 respectively.

Answer:

1-  A.  3(10÷2) +2·7

2- A.  0.4

3- B.  -2.8

4- C.  n·6 - 12 = 60

Step-by-step explanation:

Heres the work in case teachers ask:

1. The given expression evaluates to ...

30÷2 + 2·7 = 15 + 14 = 29

A: 3(10÷2) + 2·7 = 3·5 + 2·7 = 15 + 14 = 29 . . . . . this will make it true

B: 30÷(6+2)·7 = (30/8)·7 = 210/8 = 26 1/4 . . . . . . ≠ 29

C: 3(10)÷(2+2)·7 = 30/4·7 = 210/4 = 52 1/2 . . . . . ≠ 29

D: (5+2)·7 = 7·7 = 49 . . . . . . . . . . . . . . . . . . . . . . . ≠ 29

2. You can divide the equation by 10 to find the appropriate value of x.

4/10 = 10x/10 = x . . . . . 4/10 matches choice A

3. The expression simplifies to ...

7.5 -10.3 = -2.8 . . . . . . matches choice B

4. "The product of a number and 6" is n×6. Twelve less is n×6 - 12. When that "is 60", the equation can be written ...

n×6 - 12 = 60 . . . . . . . . matches selection C

Your answer is c i remember doing this from yesterday and i got the right answer i did that whole thing yesterday.

Answer:

R=50 degrees

Step-by-step explanation:

All of the angle measures together are 180 degrees. You need to make an equation in order to solve this problem:

180= (3x+5) + (11x-1) + (5x+5)

You then combine like terms:

180= (3x+11x+5x) + (5-1+5)

180= 19x+9

Then, subtract 9 from 180:

171= 19x

Then, divide 171 by 19:

9= x

Finally, you plug the value of x into the equation representing angle R:

5 x 9 + 5

45 + 5

Answer:

[tex]Change = \$10.25[/tex]

Step-by-step explanation:

Given

[tex]Individuals = 4[/tex] (You and 3 friends)

[tex]Total = \$20.00[/tex]

[tex]Movie = \$6.25[/tex] per individual

[tex]Popcorn = \$3.50[/tex]

Required

Determine the change

First, we need to determine the total amount spent on movie ticket.

The question does not state whether I pay for my friend's ticket.

So, we'll work on what is obvious.

i.e

[tex]Amount\ Spent\ on\ Ticket = \$6.25[/tex]

Add this amount to the amount spent on popcorn

[tex]Amount\ Spent =\$6.25 + \$3.50[/tex]

[tex]Amount\ Spent =\$9.75[/tex]

To get the Change, we have to deduct the total amount spent from the amount given by mom

[tex]Change = \$20 - \$9.75[/tex]

[tex]Change = \$10.25[/tex]

Hence:

The change is $10.25
