Well think about how many months there’s are!
12 right?
So 12 is the total of months or the denometor
Or bottom number ^^
Now how many months have 31 days?
Figure that out and that your numerator
Answer: 18
Step-by-step explanation:
2 degrees per hour
9 hours
1hour = 2 degrees
2hours= 4 degrees
3hr= 6 degrees
4hr= 8 degrees
5hr=10 degrees
6hr= 12 degrees
7hr= 14 degrees
8hr= 16 degrees
9hr= 18 degrees
So you are basically doing 2x9 to get your answer
<h2><em>Width=w

Answer:
-3x + y = 8.
3y = 9x.
Step-by-step explanation:
To find the slope of the lines we convert to slope-intercept form, which is
y = mx + c (m is the slope.)
The slope of y = 3x + 5 is therefore 3.
Parallel lines have the same slope.
Finding the slope of the given lines:
-3x + y = 8
y = 3x + 8 - slope is 3 so this is parallel to y = 3x + 5.
3y = 9x
Divide through by 3:
y = 3x - so this is also parallel to 3x + 5.
y = -jx The slope is -j so it is not parallel.
16x + 2y = 12
2y = -16x + 12
y = -8x + 6 - Not parallel.
To make a cake :-
Quantity of flour needed = 500 g
Quantity of butter needed = 450 g
Quantity of sugar needed = 470 g
Quantity of mixed fruit needed = 1.8 kg = 1000 g + 800 g
Quantity of eggs needed = 70 × 4 = 280 g
It's weight after adding all the ingredients =
=500 + 450 + 470 + 1000 + 800 + 280
= 3500 g
Mass that got lost while baking the cake :
<h3>= 12 % of 3500 </h3>
Final mass = Initial mass - mass that got lost
∴ The final mass of the cake is 3080 g .
