So for this question (for finding x and y) you will want to use elimination. To do this you will need to bring the x and y to the same side (I put them on the left):
-3/2x+y=6
x+y=0
Now subtract the y on the bottom from the top to isolate x:
3/2x=6
Now the easiest way to bring over the 3/2 to isolate the x fully is to convert it to decimal (1.5) and divide it by 6 (because when multiplication on one side of problem the only way to bring it over is to divide):
x=6/1.5
which simplifies to:
x=4
Hope this helps!
Answer:
Step-by-step explanation:
Given
--- slots
i.e. even numbers between 1 and 34 (inclusive)
Required
The probabiity of winning is the number of even numbers divided by the total slot;
i.e.
So, we have:
What's a hundredth?
it's like this:
0.01
so where is the hundred place in this number?
389.9<em>9</em>3
it's the 9 that i made boldface
so to round to this number we delete everything after it, asking ourselves if the number after it is 4 or less? yes! so we can just delete it without changing anyway
389.99
Answer:
constant.
Step-by-step explanation:
like natural constants like pi or e.
Answer:
$34.58
Step-by-step explanation:
If each bag of flour cost $2.47, then;
1 bag = $2.47
To calculate the cost of 14bags;
14 bags = x
x is the cost of 14 bags
Divide both expressions
1/14 = 2.47/x
cross multiply
1 * x = 14 * 2.47
x = $34.58
Hence Chazmire spent $34.58 on flour
