3. First, turn the fractions into improper fractions
11/8 + 11/4
Since we can't divide 11 by 2 to make the denominator of the first fraction 2, let's multiply both sides of the second fraction by 2 instead.
11/8 + 11*2/4*2 = 11/8 + 22/8
33/8, or 4 1/8
(I already answered numbers 4 and 6 in a previous question you asked)
5. 1 1/2 + 2 3/4
Obviously, we'll start by converting the fraction into improper fractions.
3/2 + 11/4
Multiply both sides of the first fraction by 2
3*2/2*2 + 11/4 = 6/4 + 11/4 = 17/4
17/4, or 4 1/4

You've been doing that all this time and didn't even realize it !
Every plain old number that you ever see is a rational number.
Every equation that has plain old numbers next to the variables
is an equation with rational coefficients.
If a variable ever has (pi) or a square root or a trig function next to it,
then that's an irrational coefficient. But I'll just bet you haven't ever
seen any of these yet.

1/3x + y = 2
y = -1/3x + 2
From this form, we can see that the y-intercept is 2. So that point on the graph is (0, 2). Now let's find another point. Set x equal to 3. So
y = -1/3 (3) +2
y = -1 + 2 = 1
So our point is (3, 1)
Use these 2 points to graph the equation. To find other points you could use the slope to find them. The slope is represented by x in the equation (-1/3). Or you could set another x point and solve for y again. See the pic for the graph.

so you get the amount of cereal in a [eg 40] then you divide it by 10 you get [4] each cup is worth [4] then you divide b [eg 56] by [4] giving you [14] so you get [4]

Answer:
x=0
Step-by-step explanation:
24+x=9x+4*6
First, simplify 4*6 into 24:
24+x=9x+24
No, subtract 24 on each side:
x=9x
This wouldn't be possible except with one number that could represent x:
0.
If we substitute in 0 for x, we get:
0=9*0
9*0 is 0:
0=0
Hey! That looks like a koamoji!! :P
But it means, 0 equals 0.
Which is correct.

Answer: Less, 44 cents
Step-by-step explanation: The new price is 5/4 of a dollar and in decimal form would be 1.25. The old price is 1.69 dollars meaning the new price is a better deal. To find the difference we subtract 1.25 from 1.69 giving us $0.44
