Answer:
25 and 21 hours respectively
Step-by-step explanation:
Let the number of hours worked by each welder be x and y respectively.
They worked a total of 46 hours. This means :
x + y = 46 hours.......(I)
Now, given their hourly charges, since we have the total amount of money realized, we can make an equation out of it. This means:
34x + 39y = 1669........(ii)
We then solve both simultaneously. From I, x = 46 -y
We can substitute this into ii
34(46 -y) + 39y = 1669
1564 -34y + 39y = 1669
5y = 1669 - 1564
5y = 105
y = 105/5 = 21
x = 46 - y
x = 46 - 21 = 25 hours
The numbers of hours worked by the welders are 25 and 21 respectively
9 * 3/4 = 6.75
You could change 3/4 into a decimal by dividing 3 by 4, which equals ,75.
Answer:
85 ° is the answer to the question
Answer:
see below
Step-by-step explanation:
1/12 - 5/6 = -9/12
We need to get a common denominator of 12
1/12 - 5/6*2/2 = -9 /12
1/12 - 10/12 = -9/12
Since the denominators are the same, we can subtract the numerators
1-10 = -9
-9/12 = - 9/12
We can simplify -9/12 by dividing the top and bottom by 3
-9/3 = -3
12 /3 = 4
-9/12 = -3/4
