Answer:

-6=7 NO SOLUTION

Step-by-step explanation:

First, distribute the -3 to the (k +2)

Your equation becomes, -3k-6=-3k+7

Add 3k to both sides to have the variables be on the same side

Your equation becomes, -6=7

Since that isn’t true, it’s a no solution

I hope this helps!

A chemistry teacher needs to mix a 20% salt solution with an 80% salt solution to make 20 qt of a 40% salt solution. How many qu
Svetlanka [38]

Answer:

  • 6 2/3 qt 80%
  • 13 1/3 qt 20%

Step-by-step explanation:

It is often convenient to solve a mixture problem by letting a variable represent the quantity of the higher-concentration contributor to the mix.

__

We can let x represent the number of quarts of 80% solution needed. Then (20-x) is the number of quarts of 20% solution needed. The amount of salt in the final mix is ...

  0.80x +0.20(20-x) = 0.40(20)

  0.60x = 0.20(20) . . . . . . . . subtract 0.20(20) and simplify

  x = 20/3 = 6 2/3 . . . . . . . . . divide by 0.60; quarts of 80% solution

  (20 -x) = 13 1/3 . . . . . . . . . . amount of 20% solution needed

The teacher should mix 6 2/3 quarts of 80% solution with 13 1/3 quarts of 20% solution.

A standard dartboard has a diameter of 18 in. What is its area to the nearest square inch?
Reptile [31]
The meaning of the area is the measurement of a surface in this case a circle, which can be find by using the formula A= \pi r^{2}, where r is equal to the radius of the circle.

In this exercise is given that the diameter of a standard cardboard is 18 inches or a radius of 9 inches and it is asked to find its area. Therefore, to find the area of the circle you should substitute the value of the radius into the previous mention formula.

A= \pi r^{2}
A= \pi (9 in)^{2}
A= \pi (81 in^{2})
A=254.47 in^{2}

The area of the standard dartboard is 254.47 square inches or 254 square inches.
