Solve the following equation for y.
labwork [276]

Answer:

17

Step-by-step explanation:

2y+2=36

Let's solve this equation for 2y first.  This means get 2y by itself.

So to get 2y by itself I need to undo that addition of 2 next to it.

The inverse operation of addition is subtraction.

I'm going to subtract 2 on both sides:

2y      =36-2

2y      =34

Now we want to get y by itself so we divide both sides by 2 since division and multiplication are inverse operations:

 y=        34/2

 y=        17

At Dave's diner, 2 sandwiches and 2 drinks cost $12. You can buy 5 drinks for the cost of one sandwich.
hram777 [196]
If you’re asking for the cost of the drink, the drink would be $1. This is because 2 sandwiches would cost $10 and that means 1 sandwich would make it $5. If 2 sandwiches cost $10, the remaining $2 in the $12 dollars would be the drinks. 2 drinks for $2 would make 1 drink for $1. So the cost of 5 drinks is $5 or $1 per drink.

If confused, don’t be shy to ask :)

Easy points
goblinko [34]

Answer: 2

Step-by-step explanation:

try each value in the equation

2(0) + 1 = 3

0 + 1 = 3

1 ≠ 3

so 0 doesn’t work

2(1) + 1 = 3

2 + 1 = 3

3 = 3

this works, so the answer is 1

What is the function for a table with a domain of 5, 10, 15, 20 and a range of 40, 80, 120, and 160
kykrilka [37]
To find the range we need to find the vertex of the parabola which is at (-b/2a , y)

-b/2a would be 2/2 = 1 ... so find the y value at x = 1

12 - 2(1) - 15 = 1-17 = -16

So the vertex is at (1,-16)

Since the parabola opens upward from that point the minimum value of the range is y = -16

The range would include the point -16 so it is actually

R = [-16,infinity)

Maurice has three 20 bills two 10 bills 10 quarters 12 nickels and 2 pennies. If he donates an equal amount of hop is money to 4
saveliy_v [14]
Aloha!
 First, add $20 and $20 and $20 and $20 because of the one $20 bill and the two ten dollar bills. 

Add the 10 quarters which is 2.50 and add 12 nickles 60 cents or .60 then add 2 pennies.
 The answer is $83.12 cents.
 Now divide that by 4 which is 20.78
 So to answer your question: 20.78 is how much each charity would get.
I hope this helps!:)
