Hi there! :)

Answer:

K=6.8

*The answer must have a decimal point.*

Step-by-step explanation:

First, you switch sides.

$k+8.2=15$

Then, you subtract by 8.2 from both sides of an equation.

$k+8.2-8.2=15-8.2$

Subtract by the numbers from left to right.

$15-8.2=6.8$

Final answer is k=6.8

Hope this helps!

Thanks!

Have a nice day! :)

Answer:

$4.32*10^{5}$

Step-by-step explanation:

Given the expression $4.9*10^{5}-5.8*10^{4}$ , to solve the expression, we need to write both scientific notation to the same power of 10.

$5.8*10^{4} is \ expressed\ as \ 0.58*10^{5}$

The expression above becomes $4.9*10^{5}-0.58*10^{5}$ . On taking the difference;

$4.9*10^{5}-0.58*10^{5}\\= (4.9-0.58)*10^{5} \\= 4.32*10^{5}$

The final expression gives the right answer

PLZ HELP ASAP.....Your dad is researching landscaping companies to come put new mulch out for the year. The first company charge

Blizzard [7]

Answer: After 5 bags of mulch, the cost for both companies will be the same.

Step-by-step explanation:

The cost for Company can be represented by the equation: y= 10m+100

The cost for Company B can be represented by the equation: y= 30m

To find the amount of mulch, their cost needs to be the same, I will solve for m

10m+100=30m

-10m 10m

100=20m

Divide both side by 20

100/20=20m/20

5=m or m=5

So after 5 bags of mulch, the total cost for both companies is the same.
