Answer:
Step-by-step explanation:
5/1 - 5/7
35/7 - 5/7
= 30/7 = 4 2/7 lb
Multiply the denominators, 7 by 5,and 1 by 7. When you have the same denominator in each fraction you can subtract. (7x4= 28, 30-28= 2)
Answer:
28.
a. false
b. true
c. false
d. false
2. 8.4 X 2.3 X 2.09 = 40.3788
3. $10.04 - $13.47
4. Your friend would be incorrect because their decimal is in the wrong place. Take the decimals out of it and think about it. Can 1 times 2 equal anything near 31? no, so it's not reasonable that your friend could multiply 1.2 X 2.6 and get anything near 31.2
5. It is more reasonable to say between 5 and 6 because even when you round both of the numbers up (3 X 2), you still only get 6.
Step-by-step explanation:
ill put it in the comments so I can get this to you faster.
Align the horizontal edge of the protractor with the base of the triangle. Place the center point of the protractor on the vertex of the angle. Follow the side of the triangle until it reaches the angle measurement mark. Note the measurement.

Answer: y</h3>
This is because y is a factor of 5y and it's also a factor of y^2 = y*y
It's the largest common factor between the two given expressions.
The operation is known as rounding of a number.
This means basically if i measure the temperature of a city and it comes out to be 22.9 degrees. I will round it of to 30 degrees or the amount of significant figures i am designated with.
Similarly if its 22.85 and i have to round of to 3 significant figures it becomes 22.9 degrees.
ROunding off is obviously done watching to which digit we have to.
