Answer:
distance = 5 units
Step-by-step explanation:
In order to solve this problem we can start by plotting the two points you were provided with (see attached picture). This will help us visualize the problem better.
Now, we need to find the distance between those two points, so in order to do so we can use the distance formula:
in this case the x's and y's are given by the given points, since they are written as ordere pairs. And ordered pairs are written in the form (x,y). So for Point C:
C=(-1,4)
and for point D
D=(2.0)
so we can now use those values in our distance formula so we get:
d=5 units.
Answer:
It's just a simultaneous equation
Step-by-step explanation:
Let a big bag of sugar = x
Let a small bag of flour = y
x+x+y = 12kg
2x+y = 12kg ... 1
x-y = 2kg ... 2
Add 1 and 2
2x+y = 12
+
<u> </u><u> </u><u>x</u><u> </u><u>-</u><u>y</u><u> </u><u>=</u><u> </u><u> </u><u>2</u>
3x = 14
x = 14/3 = <u>4.66</u>
Substitute value of x into 1
2(4.66)+y = 12
9.333 + y = 12
12 - 9.333= 12
y = <u>2</u><u>.</u><u>6</u><u>6</u>

And I hope my answer was of help to you.
When you subtract a negative number, add the values.
245+57=302
Final answer: 302
