Chyanee's meal cost $30.25 and Tango's meal cost $25.75. Chyanee treats Yanci by playing for both meals and leaves a 10% tip. Explain in writing (typing) how to find the amount both meals cost,the amount of the tip and the total amount of money Chyanee spent.(Remember to write 5 or more complete sentences.)​

D

let's rewrite this

x + y = 11                  - equation 1

   - x = - y - 9           - equation 2

solve the first equation for x

x + y = 11            (add -y to both sides to get x by itself)

     x = -y + 11           - equation 3

now substitute -y + 11 for x in the second equation

 y - 11 = - y - 9        (2 negative signs next to each other equals positive)

2y - 11 = -9              (add y to both sides)

      2y = 2               (add 11 to both sides)

        y = 1                (divide both sides by 2)

now substitute y = 1 into equation 3

x = -1 + 11

x = 10

therefore, x = 10 and y = 1. in coordinates, x goes before y

therefore, the coordinates are (10, 1)

therefore the answer is D

good luck my friend! hope this helped a lot! also, i found a website if you don't fully understand this, its called MathPapa, i didn't use it to work this out so my working might be different but it definitely helps me sometimes. for an equation like this, type it likes this: x+y=11; -x=-y-9

$25.46

Step-by-step explanation:

6x + 18, that is the answer

Answer:

3

Step-by-step explanation:

Because y/x=k and the point you're given is (5,15), so when you use the formula on that point it would be 15/5, which would simplify into 3/1 or 3.

Answer:

y = -2x + 1

Step-by-step explanation:

The equation is in standard form, first, we need to convert it to slope-intercept form.

5 = -10x - 5y

5 + 10x = -5y

Divide both sides by -5 to isolate y variable.

y = -2x - 1

If the line is parallel, the slope remains the same.

To find the y-intercept, you need to plug the values of x and y into the equation, which is y = 2x + b

5 = -2(-2) + b

5 = 4 + b

1 = b

The equation is -2x + 1

Answer:

101.25 seconds.

Step-by-step explanation:

We know that Ed solved the puzzle 3/4 faster than Brett.

Then if Brett solved the puzzle in a time T, Ed solved the puzzle in a time (3/4)*T.

We know that Brett solved the puzzle in 135 seconds, then:

T = 135s

This means that Ed solved the puzzle in:

time = (3/4)*T = (3/4)*135s = 101.25 seconds.

Answer:

e<12 mean in this context means that the number of eggs in the carton is not up to 12

Step-by-step explanation:

The number of eggs in the carton = 12

The capacity of egg carton is depicted as e

Hence, the inequality e<12 in this context means that :

The number of eggs in the carton is less than the capacity of the egg carton

Thus we can conclude that the number of eggs in the carton is not up to 12, which is the number of eggs the carton can hold.

Step-by-step explanation:

Answer:

Nalani is correct.

Step-by-step explanation:

Given - Nalani says the expression 9+7r cannot be factored using the GCF.

To find - Is she ​correct? Explain why or why not.

Proof -

GCF - Greater Common factor

Given that, the expression is - 9 + 7r

As

HCF(9, 7) = 1

So , we can not factor the expression.

i.e. there does not exist any number who is a multiple of 9 and 7 both.

So,

Nalani is correct.

Example -

Let the expression be 24 + 18x

HCF(24, 18) = 6

So,

24 + 18x = 6(4 + 3x)

Answer:

Step-by-step explanation:

The number of students that  should the teacher predict will participate in the program is option C. 108 students

Since 15% of the students would be interested in a summer creative writing program and there are 720 students

So, the number of students should be

= 15% of 720

= 108

Therefore, The number of students that  should the teacher predict will participate in the program is option C. 108 students
