Answer:

No, she tipped about 18%.

Step-by-step explanation:

How much she tipped:

$25 - $21.18 = $3.82

To find the percentage, you can put this tip over the what she paid for the pizza.

[tex]\frac{3.82}{21.18} =0.18=18%[/tex]%

She only tipped about 18%

Answer:

42

Step-by-step explanation:

times 70 by two to get how many notebooks needed total.

70*2=140

subtract how many notebooks you already had.

140-98=42

The no. of notebooks we need more will be equal to 42 notebooks.

It is given that no. of notebooks available is 98 and there are 70 children in class.

We have to find no. of notebooks needed more if each child gets two notebooks.

What is algebra ?

Algebra is the branch of mathematics that deals with various symbols and the arithmetic operations and the symbols are called variables.

As per the question ;

No. of notebooks we had in class = 98 notebooks

And

Total no. of children = 70 children

The no. of notebook each child gets = 2 per child

So ;

70 children will get no. of notebooks ;

= 70 × 2

= 140 notebooks

The no. of notebooks we need will be ;

= 140 - 98

= 42 notebooks

Thus , the no. of notebooks we need will be equal to 42 notebooks.

Answer:

a. From any point on the graph, he counts down 2 then right 3 to end up on the line again.

Step-by-step explanation:

The slope is -2/3.

-2/3 = 2/-3

slope = rise/run

rise/run = -2/3

Count down 2 and right 3.

rise/run = 2/-3

Count up 2 and left 3

Step-by-step explanation:

given:

−4x² y+5x+5−3x+4x² y−8

=−4x² y+4x² y+5x-3x+5-8

=2x-3

hope it helps!!

Let's simplify step-by-step.

(−4x2)(y)+5x+5−3x+4x2y−8

=−4x2y+5x+5+−3x+4x2y+−8

Combine Like Terms:

=−4x2y+5x+5+−3x+4x2y+−8

=(−4x2y+4x2y)+(5x+−3x)+(5+−8)

=2x+−3

Answer: Im gonna take you down like a sweet muffin.

The number of escapes, takedowns and nearfalls Anahi have is 6, 24 and 70 respectively.

escape is worth 1 point,

a takedown is worth 2 points, and

a nearfall is worth 3 points.

escape = x

takedown = y

nearfall = z

x + y + z = 100. (1)

x + 2y + 3z = 240. (2)

y = 4x. (3)

substitute (3) into both equation

x + 4x + z = 100

x + 8x + 3z = 240

5x + z = 100. (4)

9x + 3z = 240. (5)

Multiply (4) by 3

15x + 3z = 300 (6)

9x + 3z = 240. (5)

Subtract (5) from (6) to eliminate z

6x = 60

x = 60/6

x = 6

Substitute into (3)

y = 4x

y = 4(6)

y = 24

Therefore, from (1)

x + y + z = 100.

6 + 24 + z = 100

30 + z = 100

z = 100 - 30

z = 70
