Answers

Answer:

1 3 4

Step-by-step explanation:

umm i suck at explaining sorry

Answer: Multiplying both sides of the equation by 3

substituting 36 for p to check the solution

Step-by-step explanation: To undo the division of p by 3, one multiplies by the inverse of 1/3. That is, one multiplies by 3.

Then you have 3(p/3) = 3(12)

p = 36 simplify

To check this work, you can substitute 36 for p:

36/3 = 12 true statement So, the solution process is multiply both sides of the equation by 3 substitute 36 for p to check the work

A farmer had 22.75 bushels of corn. He sold 12 2/5 bushels at the market. His three friends bought the remaining bushels of corn. If each person bought the same amount, how many bushels did each friend purchase?

Answers

Answer:

Each friend bought 3.45 bushels of corn.

Step-by-step explanation:

12 2/5 as a decimal is 12.40. You do 22.75 minus 12.40, which gives you 10.35. Next you do 10.35 divided by 3, which gives you your final answer of 3.45.

if you reflect any shape across the x-axis and then rotate it 90 degrees clockwise about the origin, do you get the same results as if you reflect it across the y-axis and then rotate it 90 degress counterclockwise about the origin? what does this mean?

Answers

Yes, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise direction around the origin to achieve the same results as a shape reflected across the y-axis and rotated in a counterclockwise direction. This implies that these two transformational sequences are similar.

What is reflection in Mathematics?

A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.

Cheerios $3.89 for 17 oz. $ [ Select ] per ounce VS. Option 2: Apple Jacks $2.89 for 13 oz. $ [ Select ] per ounce Which is the better deal?

Answers

I think your best bet is to go with Apple Jacks.
The better deal is Cheerios because
If you take the ounces for each (17 & 13)
And divide them by the price ($3.89 & 2.89)
It would give you the amount 1 ounce would be (aka the constant) and the constant for Cheerios is 4.3701 where as the constant for Apple Jacks is 4.4981. Therefore, Cheerios is the better deal cause you get more.
