Answer:
50%
Step-by-step explanation:
you divide 81.90 by 163.80 and get .5 so then you move the decimal over 2 times to get a percent which is 50%
So this one is a little tricky because in order to solve you need to combine like terms. The only problem is that two fractions don't have the same denominator.
This is what you do.
2/3 - 1/9
= (2*9) - (1*3) / 3*9
= 18 - 3 / 27
= 15/ 27
Simplify.
5/9 + y = 7/9
Now since you need to isolate the variable you have to subtract 5/9 from both sides. Since the denominator is the same you can just subtract the numerator.
So y = 2/9
I hope this helps love! :)
Answer:
1680 miles
Step-by-step Explanation:
There are 52 weeks in a year. Total number of days she is expected to work would be 52 * 5 = 260 days.
Now we know she has 10 vacation days and 10 holidays. This translates 260 - 20 = 240 days
Now if she drives 35miles 5 days of the week, this means she dives 7 miles per day.
The total number of miles traveled is this 240 * 7 = 1680 miles
Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
To find x subtract the sum of the 2 given angles from 180, that is
x = 180° - (32 + 52)° = 180° - 84° = 96°
-------------------------------------------------------
x and y form a straight angle, hence
y = 180 - x = 180° - 96° = 84°
------------------------------------------------------
To find z subtract the sum of the 2 angles from 180
z = 180° - (55 + y)° = 180° - (55 + 84)° = 180° - 139° = 41°
--------------------------------------------------------
x = 96°, y = 84°, z = 41° → A
