You know you need to rename a mixed number to subtract when the numbers involved have different denominators. In such a case. The lowest common multiple of the denominators will be calculated subsequent used to adequately rename the mixed numbers before subtraction can be done

Answer this please and the first person to do it will get Branilest !! Don’t forget to explain
Mandarinka [93]

Answer:

3g + 9g =  - 48 \\ 12g =  - 48 \\ g =  -  \frac{48}{12}  \\ g =  - 4 \\  \\   - 4m - 6m - 30 =  - 80 \\  - 4m - 6m =  - 80 + 30 \\  - 10m =  - 110 \\ m =  \frac{ - 110}{ - 10}  \\ m = 11 \\  \\ 12 =  - 8n - 24 - 4n \\ 12 + 24 =  - 8n - 4n \\ 36 =  - 12n \\ n =  \frac{36}{ - 12}  \\ n =  - 3 \\  \\ 5y + 2y +  \frac{1}{2}  =  -  \frac{1}{2 }  \\ 5y + 2y =   - \frac{1}{2}   -  \frac{1}{2}  \\ 7y =  - 1 \\ y =  -  \frac{1}{7}  \\  \\ 22x + 0.25 - 16x = 0.85 \\ 22x - 16x = 0.85 - 0.25 \\ 6x = 0.6 \\  x =  \frac{0.6}{6}  \\ x = 0.1 \\  \\ 17k + 6k + 11 = 80 \\ 17k + 6k = 80 - 11 \\ 23k = 69 \\ k = 3

Does this graph represent a function? Why or why not?
ExtremeBDS [4]

A Function is defined as the relation between the input and the output where one input can have only one output

When graphing functions, the x-axis denotes the inputs and the y-axis denotes the output of the function

Looking at the graph, we see that for one input (point on the x-axis) we have only one output (point on the y-axis)

Hence, we can say that this graph represents a function

Chase has 3 gallons of a solution that is 30% antifeeze that he wants to use to winterize his car. How much pure antifreeze shou
makvit [3.9K]

Let  x gallons be the amount of pure antifreeze that should be added to the 30% solution to produce a solution that is 65% antifreeze. Then the total amount of antifreeze solution will be x+3 gallons.

There are 30% of pure antifreeze in 3 gallons of solution, then

3 gallons - 100%,

a gallons - 30%,

where a gallons is the amount of pure antifreeze in given solution.

Mathematically,

\dfrac{3}{a}=\dfrac{100}{30},\\ \\a=\dfrac{3\cdot 30}{100}=0.9\ gallons.

Now in new solution there will be x+0.9 gallons of pure antefreeze.

x+3 gallons - 100%,

x+0.9 - 65%

or

\dfrac{x+3}{x+0.9}=\dfrac{100}{65},\\ \\65(x+3)=100(x+0.9),\\ \\65x+195=100x+90,\\ \\35x=105,\\ \\x=3\ gallons.

Answer: he should add 3 gallons of pure antifreeze.
