CXB = 40 degrees
I am not positive but from what I have looked up this is the answer.
Answer:
3/14
Step-by-step explanation:
5/7 minus 1/2 is 5/7 - 1/2
5/7 and 1/2 are both called proper fractions. 5 and 1 in each fraction are called the numerator while 7 and 2 are called denominators
5/7 - 1/2
Step one
Find the lowest common multiple (LCM) of the denominators of each fractions
Multiples of 7
7 x 1 = 7
7 x 2 = 14
7 x 3 = 21
Multiples of 2
2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8
2 x 5 = 10
2 x 6 = 12
2 x 7 = 14
The lowest common multiple of 2 and 7 is 14
Step 2
The LCM of 2 and 7 becomes the common denominator for both fractions.
14/7 = 2
14/2 = 7
5/7 - 1/2 = [2(5) - 7(1)]/14 = (10 - 7)/14
= 3/14
Answer:
60 barrels
Step-by-step explanation:
y = # of barrels; x = minutes
worker: y = 12x
old line: y = 2x + 50
12x = 2x + 50
10x = 50
x = 5
y = 12(5) = 60
y = 2(5) + 50 = 60
60 barrels
Divide each side by 2 1/4 to get x by itself. The answer is -24 < x and the sign didn't change because we didn't divide by a negative.
