Answer:

Solution,

X=8

y=4

Now,

 $\frac{x + 10}{y + 5} \\ = \frac{8 + 10}{4 + 5} \\ = \frac{18}{9} \\ = 2$ 

hope this helps...

Good luck on your assignment..

Anna made and sold x ceramic vases one week. Her profit, P, in dollars is calculated using the formula P = R - C . Where R repre

Alex73 [517]

Answer:

-0.5x² + 20x + 100

Step-by-step explanation:

Given:

R = 25x - 0.5x²

C = 100 + 5x

P = R - C

Where,

P = profits

R = Revenue

C = Cost

which expression represents her profit in dollars?

P = R - C

R = 25x - 0.5x²

C = 100 + 5x

= 25x - 0.5x² -(-100 + 5x )

= 25x - 0.5x² + 100 - 5x

= -0.5x² + 20x + 100

The expression which represents her profit in dollars is -0.5x² + 20x + 100

3x = 2x + 7 4 5 x = ?

Alexxandr [17]

<h2>Solve for x | Solution and Explanation</h2>

_______________________________________________

We are given the following expression:

$\frac{3x}{4} =\frac{2x+7}{5}$

1. Apply fraction cross multiply (if $\frac{a}{b}=\frac{c}{d}$ , then $a$ × $d$ = $b$ × $c$ )

$3x$ × $5 = 4(2x+7)$

==================

2. Simplify.

$15x=4(2x+7)$

==================

3. Expand 4(2x + 7).

$15x=8x+28$

===========================

4. Subtract 8x from both sides.

$15x-8x=8x+28-8x$

=======================

5. Simplify.

$7x=28$

=======================

6. Divide both sides by 7.

$\frac{7x}{7}=\frac{28}{7}$

========================

7. Simplify.

$x=4$

=========================

Hope this helps!

What is 3/10, -1 1/3, 0.02, 1, -0.5 in order form least to greatest

baherus [9]

Answer:

-1 1/3, -0.5, 0.02, 3/10, 1

Step-by-step explanation:

To start off with, we now that negative numbers (like -3) are less than 0. We are given two negative numbers to start off with: -1 1/3 and -0.5. The larger/greater the negative number is, the lesser it is worth. Take out a number line. For example, -5 is less than -3 because if you look at a number line, -5 is further to the left of 0 than -3, signifying it is less than -3. So, when looking at -1 1/3 (also can be represented by the decimal number (-1.33...) and -0.5 we see that -1 1/3 is less than -0.5. due to it being further from 0 than -0.5 is. Thus, we have our least number.

-1 1/3

Since we have only one more negative number left, we can place that as the second least number

-1 1/3, -0.5

Next, we take a look at the positive numbers 0.02, 1, and 3/10. It might be more helpful to make 0.02 into a fraction; 2/100. From here we see that one one hundredth is much less than one one tenth. Thus, the 2/100 or 0.02 is the nest least number.

-1 1/3, -0.5, 0.02

Lastly, take a look at 3/10 and 1. 1 = 10/10

When put side by side, 3/10 is seen to be less than 10/10, making it the next least number.

-1 1/3, -0.5, 0.02, 3/10

Lastly, we have our last and greatest number; 1. We can just go ahead and place that after 3/10.

-1 1/3, -0.5, 0.02, 3/10, 1

Karo-lina-s [1.5K]

Answer:

x = 15

Step-by-step explanation:

Step 1: Make an expression

4/6 = 10/x

Step 2: Cross multiply

4/6 = 10/x

4x = 60

Step 3: Divide both sides by 4

4x / 4 = 60 / 4

x = 15

Answer: x = 15
