1. The answer is 729 (Question 2 idk)
Yep!
Weighing #1: Start off by splitting the pile of 12 coins evenly into two piles, 6 in each pile. Put one pile on each side of the balance. The side that is weighed down has the fake coin it in. Ignore the other 6 coins.
Weighing #2: Now you have 6 coins left. Split the pile evenly again, 3 in each pile. Repeat the same process and put each pile on one side of the balance. The side that is weighed down has your fake coin in it. Ignore the other 3 coins.
Weighing #3: You have 3 coins left. Take two coins, whichever two you like, and weigh them. If they weigh the same, then the one you didn't weigh is the fake one. If one is heavier, then that heavier one is your fake coin.
Answer: y=4/5x-2 or y=4/5x+(-2)
Step-by-step explanation:
The formula for slope-intercept form is y=mx+b.
To find the slope, we can use the formula and plugging in the points given.
We know our slope is 4/5. We can plug this into our slope-intercept form and then plug in a point to find b, y-intercept.
We know the y-intercept is -2.
THe final equation is y=4/5x-2 or y=4/5x+(-2).
Answer: 325$
Explanation:
Assume: A is the cost of washer
And B is the cost of dryer
A+B = 744
And: A = B + 94$
We get:
B + 94$ + B = 744
2B + 94 = 744
2B = 650
B = 325
