Answer:
The values of the 2 numbers whose sum is 13 and difference is 3, are: {8 ; 5}.
Step-by-step explanation:
So for this you just want to divide 4/5 by 9/10 because it is the opposite of the equation.
9/10 / 4/5
To divide fractions, you just multiply and reverse the second fraction.
For example:
9/10 * 5/4
Now you can just normally multiply.
45/40
Or, simplified,
9/8
(Or 1 1/8)
Answer:
2nd option: 2y=6x+8 and y=3x+4
Step-by-step explanation:
If you divide the first by 2, you get the second equation.
This means that both equations plot an identical line (they lie on top of each other /also known as "coincide"). This means, that there are infinitely many solutions.
In 2D (x-y plane for example), straight lines can have no solutions if they have the same gradient/slope/ they are parallel and different y-intercepts, because they will never cross.
Here, they have same gradient and y-intercept so all points on the line are valid solutions to the equation
This division question is asking how many 1/4 you can fit into 50 1/2.
We can fit 4 of them into 1 whole (4 x 1/4 = 1)
We can fit 8 of them into 2 wholes (8 x 1/4 = 2)
and so on.
But we have 50 1/2 wholes, so we would need 50 1/2 x 4.
The new number sentence is 50 1/2 x 4.
Answer:
5) C pink 6) A -1/2x + 1/4 7) D z ≥ 0
Step-by-step explanation:
5) White 1/6 = 4/24
Green 1/3 = 8/24
Pink 1/8 = 3/24
Yellow 3/8 = 9/24
6) 11/2x - 2(3x - 1/8) Distribute the -2
11/2x - 6x + 1/4 Combine like terms
-1/2x + 1/4
7) z ≥ 0
z is greater than or equal to 0
