First off, these fractions will work to your advantage if they are in the form of an improper fraction. 7 and 3/4 as an improper fraction is 31/4. 2 and 1/3 as an improper fraction is 7/3. Now, in order to add and subtract fractions, they need to have a common denominator. 3 and 4 share a common multiple of 12. 31/4 = 93/12. (You need to multiply by the same number in the numerator as you did in the denominator. Multiply 4 by 3 to get 12. Multiply 31 by 3 to get the new numerator.) 7/3 = 28/12 (Multiply by 4 to get 12 in the denominator. Multiply 4 by 7 for the numerator.) 93/12 -28/12 = 65/12 This fraction can also be expressed as a mixed number. 5 and 5/12.
Answer:
(-3,8)
Step-by-step explanation:
Lets say two points are (x1,y1) and (x2,y2), the midpoint will be:
((x1+x2)/2,(y1+y2)/2)
Plugging the point A in, we get: the midpoint, (3,5) as (((9+x2)/2),(2+y2)/2)
We can assign x2 and y2 as variables.
(9+x2)/2=3
9+x2=6
x2= -3
(2+y2)/2=5
2+y2=10
y2=8
therefore we get the point (-3,8)
There are better ways and this is the "formulaic (ig) way" to do this
Answer:
If she invests x an y, then we have
x+y = 144800
.10x + .18y = 20000
Now just do that as a matrix equation.
