Answer:
ok then
Step-by-step explanation:
The price of the bushel is 1.22, 1.41, 1.38, and 1.27.
To calculate the weighted average, all you need to is to just add all the values given above and then divide it by 4, since we only have 4 values of the bushel.
So: 1.22 + 1.41 + 1.38 + 1.27 = 5.28
5.28 / 4 = 1.32
Round it off to only two significant figures, you would get: $1.30.
3(gameMachines) + 5(6) = 72lbs
3(gameMachines) = 42
gameMachine = 14
Answer: (4, -9)
<u>Step-by-step explanation:</u>
Use elimination method. Manipulate one (or both) equations to eliminate one of the variables and solve for the remaining variable. <em>I will be eliminating y</em>
6x + y = 15 → 2(6x + y = 15) → 12x + 2y = 30
-7x - 2y = -10 → 1(-7x + 2y = -10) → <u> -7x - 2y = -10</u>
5x = 20
x = 4
Next, replace "x" with "4" into either equation and solve for y.
6(4) + y = 15
24 + y = 15
y = -9
<u>Check:</u>
Plug in x = 4 and y = -9 into the other equation to verify it makes a true statement.
-7x - 2y = -10
-7(4) - 2(-9) = -10
-28 - -18 = -10
-28 + 18 = -10
-10 = -10 
It's 21.125 hope this works good luck ;)
