Last night, 4 friends split the dinner bill evenly. Each friend paid $12.75 and left the same amount for a tip. The bills total was $61. What equation could describe the situation?

Answers

Answer 1

Answer: 4 * (12.75 + x) = 61

Step-by-step explanation:

Each of the 4 friends paid $12.75 so that is:

= 4 * 12.75

Assuming the tip is denoted as x it would be:

= 4x

Putting them together is:

4 * (12.75 + x) = 61

Solving the equation would give:

4 * (12.75 + x) = 61

51 + 4x = 61

4x = 61 - 51

x = 10/4

x = $2.50

Simplify the following surds
a) 18
b) 12
c) 32
Will mark brainliest answer ​

Answers

Answer:

___________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

To simplify a surd , ensure that the number is expressed in such a way that it is the product of factors.Try to express the number as the product of 2 or more perfect squares (if any) because it makes the process of simplifying the surd easier.

___________________________________________________________

According to the question ,

a) [tex]\sqrt{18} =\sqrt{9 \times 2} = \sqrt{9} \times \sqrt{2} = 3\sqrt{2}[/tex]

b) [tex]\sqrt{12} =\sqrt{4 \times 3} = \sqrt{4} \times \sqrt{3} = 2\sqrt{3}[/tex]

c) [tex]\sqrt{32} = \sqrt{16 \times 2} = \sqrt{16} \times \sqrt{2} = 4\sqrt{2}[/tex]

Answers

3-5x=2

or, -5x=-1

or, x= 1/5

The value of x is 1/5 for equation 3 – 5x = 2

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is 3 – 5x = 2

Three minus five times of x equal to two

We need to solve for x

3 – 5x = 2

Subtract 3 from both sides

3-3-5x=2-3

-5x=-1

Divide both sides by -5

x=-1/-5

x equal to one by five

x=1/5

Hence, the value of x is 1/5 for equation 3 – 5x = 2

Saturday: 1.5x

Sunday: 2x

Step-by-step explanation:

    For the the Chart, Saturday, we can automatically see that when 1 is inputted into the equation we get 1.5, as anything times 1 will equal the same number inputted (x). So we can try 1.5x and plug in every other x value and see what we get:

1.5(2) = 3

1.5(3) = 4.5

1.5(4) = 6

This verifies that the equation 1.5x works with this chart.

   For the graph its simple, do rise over run and your slope is 2/1 which is 2 so we have 2x for our equation so far and now to find the + or - at the end of the equation ( the "b" variable of the mx + b form) we just look at where does the function intersect with the Y-axis. Since it is at 0 we don't need to add a "b" variable to the equation so the equation for the graph is 2x for Sunday.
