5 Pizzas
3 toppings on each

5x3 = 15 toppings total

5 Total Medium Pizzas = Each are 8.00$
15 Total Toppings = Each are 0.50$

8.00 x 5 = 40.00$
0.50 x 15 = 7.50 $

40.00 + 7.50 = 47.50$

47 dollars and 50 cents will be your answer.

As an equation it will be (5 x 8.00) + (3 x 0.50) = x

The sum of four consecutive integers is 180. What is the largest number .​
podryga [215]

Answer:

<h3>            No such four numbers</h3>

Step-by-step explanation:

x - the first number

x+1 - the number consecutive to x  (secon consecutive)

x+1+1=x+2  - next consecutive number (the third)

x+2+1 = x+3  - the last consecutive number (fourth)

x + x+1 x+2 + x+3 = 180

 4x + 6 = 180

      -6       -6

   4x  =  174

   ÷4      ÷4

   x = 43.5

It is not an integer. I means there are not four consecutive integers which gives the sum 180.

I need some help. Can someone assist me with this?​
Y_Kistochka [10]

Answer:

x = 12

WN = 28

Step-by-step explanation:

SO = WN and SO = 2WI

3x - 8 = 2(x + 2)

3x - 8 = 2x + 4

3x - 2x = 4 + 8

x = 12 now replace x with 12 in the first equation given

3x - 8 = 3×12 - 8

36 - 8 = 28

Find the expression for the area of the figure. Give your answer as a simplified radical.
Marizza181 [45]

Answer:

D

Step-by-step explanation:

Area of rectangle= length × breadth

Area of figure

= ( \sqrt{15x}) ( \sqrt{10x} ) \\  =  \sqrt{(10x)(15x)}  \\  =  \sqrt{150 {x}^{2} }  \\  =  \sqrt{6(25 {x}^{2}) } \\  =  (\sqrt{6} )( \sqrt{( {5x})^{2} } ) \\  = ( \sqrt{6} )(5x) \\  = 5x \sqrt{6}

SpyIntel [72]

Answer:

2 Gallons

Step-by-step explanation:

20.5ft x 16.4ft = 336.2

336.2 divided by 200= 168 gallons

Since you can not buy 1.68 gallons you will have to buy 2 galllons instead.
