3(2a+1)=-5(a+6)
First expand the brackets.
6a+3=-5a-30
Now add 5a to both sides.
11a+3=-30
Then subtract 3 from both sides.
11a=-33
Finally divide both sides by 11.
a=- 33/11
=-3

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
nydimaria [60]

Answer:

Step-by-step explanation:

As you can see, this is a quadratic equation and if you were to graph this you would see that it is a parabola that opens down because of the negative leading coefficient (-34). The maximum profit would be at the vertex, of the graph. Therefore, we need to find the value of "y" when "x" is the line of symmetry. We find this by  x=-b/(2a) where a = -34 and b = 1542:

x=-1542/(2)(-34)

x=-152/-68

x=152/68  

We put this value of "x" into the original formula to find out the value of "y":

y=-34x^2+1542x-10037

y=(-34)(1542/68)^2+1542(1542/68)-10037

y= -17483.5588235 + 34967.1176471 -10037

y=7446.5588236

Therefore, the maximum profit would be $7446.56.

Hope this helps!

Scott washed cars for 2 1/2 hours as a fundraiser. It took him 1/4 hour to wash one car. How many cars did Scott wash
lana66690 [7]

Answer:

He washed 10 cars.

Step-by-step explanation:

To make this easier covert 1/2hours into 1/4 hours. 2 1/2 = 4/2+1/2 = 5/2. Now take 5/2 and make it 1/4th's, 5/2 = 10/4. It takes 1/4 hours to wash one car so, 10/4 divided by 1/4. Don't divide fractions so, 10/4 x 4/1, we switch the second number around to get 40/4. Now we can simplify, 40/4 = 10.

Bogdan [553]

Answer:

24=4k

k=6

Step-by-step explanation:

For this exercise it is important to remember that "Times as great as" indicates multiplication.

Therefore, "4 times as great as" can be expressed as following:

4k

So, the statement "24 is 4 times as great as" indicates that 24 is equal to 4k.

Knowing this, you can write the following equation:

24=4k

In order to solve for "k", you can divide both sides of the equation by 4. Then, you get the following result:

\frac{24}{4}=\frac{4k}{4}\\\\k=6
