Answer:

<h2>Hello!!!</h2>

Step-by-step explanation:

The first step for solving this expression is to remove the first set of parenthesis.

-8.3x+4 - (3.2x-5)

Remember that when there is a "_" sign in front of the parenthesis, we must change the sign of the expression to the following

-8.3x + 4 - 3.2x + 5

Collect the like terms with an x variable.

-11.5x + 4 + 5

Lastly, add the number to get your final answer

-11.5x + 9

Hope that helps you dear...

Have a nice day..

Buhbye!

You are going to mix a gallon bucket of window cleaner. The instructions direct you to mix 1 part cleaner to 3 parts water. How

Ira Lisetskai [31]

3 parts water
clean:water=1:3
1:3=xcleaner:1gallon
1/3=xcleaner/1gallon
times 3gallon both sides
1gallon=3xcleaner
divide both sides by 3
1/3 gallon=xcleaner

therfor you need 1/3 gallon of cleaner

Answer:

Average speed = $\frac{(x+y)}{2}$ miles per hour

Step-by-step explanation:

Formula to calculate the average speed of an object is,

Average speed = $\frac{\text{Total distance covered}}{\text{Time taken to cover this distance}}$

If I travel with the speed of x mph for t hours,

Total distance covered = Speed × Time

= $x\times t$

= $xt$ miles

Similarly, if I travel with the speed y mph for t hours,

Total distance covered = $yt$ miles

Total distance covered by me = $(xt+yt)$ miles

Total time taken to cover this distance = $t+t$

= $2t$ hours

Therefore, expression for the average speed will be,

Average speed = $\frac{xt+yt}{2t}$

= $\frac{(x+y)t}{2t}$

= $\frac{x+y}{2}$ miles per hour
