4 1/2 + 2 4/5
4 + 2 = 6
1/2 + 4/5 = 5/10 + 8/10 = 13/10 = 1 3/10
6 + 1 3/10 =
7 3/10 <===
So for the two equations: Not sure how hard you want them but....
15+1=16 and 13+ 18=21
For the open equation.
2x + x(5+7)=105
Answer:
Step-by-step explanation:
The formula for determining the distance between two points on a straight line is expressed as
Distance = √(x2 - x1)² + (y2 - y1)²
Where
x2 represents final value of x on the horizontal axis
x1 represents initial value of x on the horizontal axis.
y2 represents final value of y on the vertical axis.
y1 represents initial value of y on the vertical axis.
From the given information,
x2 = - 1
x1 = 4
y2 = 6
y1 = 3
Therefore,
Distance = √(- 1 - 4)² + (6 - 3)²
Distance = √(- 5² + 3²) = √(25 + 9) = √34
Distance = 5.83
42.5, just need to multiply
![\frac{14}{28}](https://tex.z-dn.net/?f=%20%5Cfrac%7B14%7D%7B28%7D%20)
is our fraction, which is not in lowest form, and therefore can be reduced. We can divide both numerator and denominator by 2, and we end up with
![\frac{7}{14}](https://tex.z-dn.net/?f=%20%5Cfrac%7B7%7D%7B14%7D%20)
7 goes into 14 twice, so we can reduce it further to become
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
To convert a fraction to a ratio, you just need to turn it on its side and make the | into a : So it would look like this:
1:21 / 2 = 0.5

0.5 is the fraction in decimal formTo find a percentage, you just need to multiply the decimal by 100.
0.5 in percentage form would be 50%
Hope that helped =)
