<em><u>Question:</u></em>

A local hamburger shop sold a combined total of 695 hamburgers and cheeseburgers on Sunday. There were 55 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Sunday?

<em><u>Answer:</u></em>

375 hamburgers and 320 cheese burgers were sold

<em><u>Solution:</u></em>

Let "a" be the number of hamburgers sold

Let "b" be the number of cheese burgers sold

<em><u>Local hamburger shop sold a combined total of 695 hamburgers and cheeseburgers on Sunday</u></em>

Therefore,

a + b = 695 ------------ eqn 1

<em><u>There were 55 fewer cheeseburgers sold than hamburgers</u></em>

Number of cheese burgers sold = number of hamburgers - 55

b = a - 55 --------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

<em><u>Substitute eqn 2 in eqn 1</u></em>

a + a - 55 = 695

2a = 695 + 55

2a = 750

a = 375

<em><u>Substitute a = 375 in eqn 2</u></em>

b = 375 - 55

b = 320

Thus 375 hamburgers and 320 cheese burgers were sold

Diane's Tree Trimming Service has trimmed hundreds of trees in the Greater Denver area. The time it takes to trim a tree is norm
kkurt [141]

Answer:P(28.5And we can find this probability with this difference:

P(-0.7

And in order to find these probabilities we use tables for the normal standard distribution, excel or a calculator.

P(-0.7

So then the best answer would be 21.82 %

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the time it takes to trim a tree of a population, and for this case we know the distribution for X is given by:

X \sim N(32,5)  

Where \mu=32 and \sigma=5

We are interested on this probability

P(28.5

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:P(28.5And we can find this probability with this difference:

P(-0.7

And in order to find these probabilities we use tables for the normal standard distribution, excel or a calculator.

P(-0.7

 So then the best answer would be 21.82 %

Solve the system of equations using the linear combination method {5p-3q=-39 -2p-3q=3
VikaD [51]

Answer:

p=-6

q=3

Step-by-step explanation:

5p-3q=-39

-2p-3q=3

Multiply the second equation by -1

2p +3q = -3

Add the first equation and the modified second equation

5p-3q=-39

2p +3q = -3

---------------------

7p = -42

Divide by 7

7p/7 = -42/7

p = -6

Now we can find q

2p +3q = -3

2(-6) +3q = -3

-12 +3q = -3

Add 12 to each side

-12+12 +3q = -3+12

3q = 9

Divide by 3

3q/3 = 9/3

q=3

How can I solve 4x-2&gt;3x+5
cluponka [151]
You would move over the -2 making the equation look like this 4x>3x+7. Then move the 3x to the other side of the equation making it look like this 1x>7. Thus the answer is x>7.
