9/10. make the bottom numbers the same to add fractions. you can do that by multiplying 7/10 by 10/10.
70/100 + 20/100 = 90/100
90/100 = 9/10
you can also reduce 20/100 to 2/10.
7/10 + 2/10 = 9/10
Answer:
2 + m- 1 + m
Step-by-step explanation:
3m +1 -m
Combine like terms
3m-m +1
2m +1
We can split the m's
m+m +1
And we can rewrite 1 as 2-1
m+m+2-1
m+2+m-1
Rearranging the order
2/3 = x/(3x + y)
2*(3x + y) = 3*x
2*3x + 2*y = 3x
6x + 2y = 3x
6x - 3x = - 2y
3x = -2y
x/y = -2/3
x : y = -2/3.
To solve this problem you use the "Triangle Inequality Theorem" it states that: any side of a triangle is always shorter than the sum of the other two sides.
Using this theorem we check each side
5+7=12: this is greater than the other side which is 11, so this works
11+7= 18: this is greater than the other side which is 5, so this works
5 + 11= 16: this is greater that the other side which is 7, so this works
Your answers are:
1: 14
2: 66
3: 4
4: 1/16 or 0.0625
5: 17
6: 1
Hope this helps!
