A. One Solution.
If you distribute the 4 and 2 you're left with
8x+12=6x-8
+8 to both sides
8x+20=6x
-8x both sides
20=-2x
Divide by -2
X=-10

What is the correct answer and why show your work
Anna11 [10]

Answer:

A7.45x = y

Step-by-step explanation:


We can use a ratio to solve this problem.  Take the total cost of the lunches and divide by the number of lunches.

y = total cost of lunches and

x = number of lunches

74.50             y

-------------- = ------------

10                     x


Using cross products

74.5 x = 10 y

Divide each side by 10

74.5/10 x= 10y/10

7.45x = y

Pls help w work and explanation fast thanks

Answer:

I would choose two 12 inch pizza if I want more pizza as two 12 inch pizzas have larger circumference than one 18 inch pizza

c=πd

circumference= pie × diameter

c=2πr

circumference= 2×pie×radius

A=πr²

Area= pie×square radius

Pie= 22/7, 3.14( depends on the question, sometimes the value of pie will be given in the question)

radius= half of diameter

To find perimeter of circle use 2πr

To find area of circle use πr² or πd
