Answer:

11 bushels of apples were sold

Step-by-step explanation:

Let

x---->  bushels of peaches

y---->  bushels of apples

we know that

7x+6y=346 -----> equation A

x=y+29 -----> equation B

substitute equation B in equation A and solve for y

7(y+29)+6y=346

7y+203+6y=346

13y=346-203

13y=143

y=143/13=11

Steps to solving y=2x+3 x=y-8
tatuchka [14]
First, plug in x=y-8 to y=2x+3
Next, it would be y=2(y-8)+3
Then, you need to distribute: y= 2y-16+3
After that, move 2y to the other side: -y= -13 (notice I also did -16+3)
Finally, divide negatives into both sides: y=13

Now to find x just plug in 13 to either of the equations: 13=2x+3
Then solve: x=5
So the FINAL answer is: (5,13)
Hope this helps!!!!!!!

For all integers n, if n2 is odd, then n is odd. Use a proof by contraposition, as in Lemma 1.1. Let n be an integer. Suppose th
Reil [10]
Let's assume that the statement "if n^2 is odd, then is odd" is false. That would mean "n^2 is odd" leads to "n is even"

Suppose n is even. That means n = 2k where k is any integer.

Square both sides

n = 2k
n^2 = (2k)^2
n^2 = 4k^2
n^2 = 2*(2k^2)

The expression 2(2k^2) is in the form 2m where m is an integer (m = 2k^2) which shows us that n^2 is also even. 

So this contradicts the initial statement which forces n to be odd.

So far, 18 of the 25 students in your class have turned in field trip permission slips.

we have been asked to find

What percent of your classmates have turned in permission slips?

Required Percentage=\frac{18}{25}*100\\

Simplify we get

Required Percentage=\frac{18}{25}*100=18*4=72\\

Hence 72% percent of your classmates have turned in permission slips.
