Isolate y in the equation 3x+2y=8

Answers

Answer 1

Answer: Subtract 3x
2y=-3x+8
Divide by 2
Y=-3/2x+4

Answer 2

$2y = 8 -3x$

$y = (8-3x)/(2)$

Shirts-2-Go sells t-shirts for a base price of $12 per shirt plus a fixed fee of $3 shipping and handling for the whole order. Shirts PLUS sells t-shirts for a base price of $8 per shirt plus a fixed fee of $23 shipping and handling for the whole order. Let x represent the number of shirts ordered and let y represent the total cost of the order.y = 12x + 3

y = 8x + 23

How many shirts would you have to purchase for the total cost to be the same at both companies?

Answers

Answer:

5 shirts

Step-by-step explanation:

Y=12x+3 equation 1

y=8x+23 equation 2

12x+3=8x+23 substituting y value will cause equations to equal

4x=20

x=5 shirts

check answer

y=12x+3

y=12(5)+3

y=60+3

y=63

y=8x+23

y=8(5)+23

y=40+23

y=63

When you add numbers together and you divide it by the number of numbers you added is your mean. Like if you get a 90 and 91 You add them and divide it by 2 and that will be your mean.

If you have a set of numbers, add all the number up and divide them by how many numbers you have. Hope that helps!:)
