Answer:
54000-65000
Step-by-step explanation:
round the numbers first down to 1200 and 45, and multiply, then round up for the larger, like 1300 and 50 to get your answer.
Integers are like whole numbers, but they also include negative numbers so true
From the information given, Dairon already had a string that is 4 7/8 inches long.
We first write or simplify 3/8 and 4 7/8 in their decimal fraction forms.
3/8 is written as 0.375 and 4 7/8 is written as 4.875
We can now find out how many pieces he cut from the string (that was 4 7/8 inches), so:
4.875 ÷ 0.375 = 13
So he got 13 pieces of string. He wants 20 pieces, so;
20 -13 = 7
Therefore he will need 7 more strings .

Answer: 126 degrees</h3>
========================================================
Explanation:
Since L and M are parallel lines, this means x+y = 180 due to the same side interior angles theorem. Some books refer to these angles as consecutive interior angles.
If x+y = 180, then y = 180-x.
Plug this into the equation your teacher gave you
x/y = 3/7
x/(180-x) = 3/7
7x = 3(180-x) ... cross multiply
7x = 540 - 3x
7x+3x = 540
10x = 540
x = 540/10
x = 54
Use this to find y
y = 180-x
y = 180-54
y = 126
Then notice how x/y = 54/126 = 3/7, which helps confirm we have the correct x and y values.
Divide both parts of the first fraction by 18 to fully reduce.
Now because angles y and z are alternate exterior angles, this must mean z = y = 126 degrees
