Looks like you did most of it.

The next step would be setting them equal to 105, like the problem suggests.

5z+3x+7x=105

15x=105

x=7

Then we can plug back in to find the numbers.

5*7=35

3*7=21

7*7=49

35+21+49=105

The three numbers are 35, 21, 49.

Hope this helps.

頑張って!

Q1
Since the sum of 3 number be 105
So
5x+3x+7x=105
15x=105
X=7
1st number=35
2nd number=21
3rd number =49

Q2
Let first number be=x
Second number be=2x
Sum of this two number is 24
so x+2x=24
3x=24
X=8
1st number=8
2nd number=16

Hope this can help.

Mike drank more than half the juice in his glass. what fraction of the juice could Mike have drunk?
maxonik [38]
He drank more than half of his drink... So we need to look for fractions greater than 1/2.

First, lets find equivalents of 1/2

\frac{1}{2}= \frac{2}{4} = \frac{3}{6}= \frac{4}{8}

If all of these fractions are equal to 1/2, then by adding to the numerator of these fractions, we'l have fractions greater than 1/2.

 2 +1 3
__= ___
 4      4

3/4 is greater than 1/2

Mike could have drunken 3/4 of the juice

4/6>1/2 Mike could have drunken 4/6 of the juice

5/8 is greater then 1/2 Mike could have drank 5/8 of the drink.

Answer=3/4, 4/6, 5/8 and many more possible fractions

azamat
To find the x coordinate of the midpoint, add the x coordinates and divide by 2
(-5+3)/2 = -2/2 = -1
To find the y coordinate of the midpoint, add the y coordinates and divide by 2
(3+-1)/2 = 2/2 = 1
