Answer:

x=10

Step-by-step explanation:

Set up a proportion with corresponding sides. The two sides marked with a small line in them represent that those sides are equal. Therefore, the side marked 30 is broken into two lines of equal length (each 15).

Thus, we can set up the following proportion:

\frac{x}{20}=\frac{15}{30},\\\\30x=300,\\\\x=\boxed{10}

3. Wanda bought a share in Tasty Ice Cream for $25 on March 1. On June 13, Tasty Ice Cream's shares were trading
Gnesinka [82]

Answer:

D) Wanda will receive $23.50 for her share, meaning she lost $1.50 on the investment.

Step-by-step explanation:

Identify what you know:

1) Wanda bought a single share in Tasty Ice Cream for $25.00 on March 1st.

2) Tasty Ice Cream's stock price dropped to $23.50 (-1.50).

When investing in the stock market, you are always attempting to make a profit. So, you buy a stock when it's "low," and buy it when the prices go up. In reality, Wanda shouldn't sell her share yet, because she will lose $1.50. However, there is nothing stopping her, if she wanted to. Since the share is worth $23.50, Wanda will make $23.50 if she sells her share on June 13th.

Celeste wants to have her hair cut and permed and also go to lunch. She knows she will need $68. The perm costs twice as much as
bixtya [17]
Okay!

1. Take the $68 and subtract $5 from it for lunch
         
                            68
                         -    5
                        _____

                            63

2. Take your $63 and divide by 3. 

 (we are dividing by 3 because we know that she wants a haircut and a perm, but a perm costs twice(2) as much wich means we need to find how much one haircut is.)
            
                               
                            3 divided by 3 = 21

3. Now you have a 21. 

$21 = 1 haircut 

21+21= $42 =1 perm   (because the perm is twice the cost of the hair cut)

4. Add all together to make sure you have your numbers right!

$21(haircut)+$42(perm)+$5(lunch)= $68

Hope this helped!

If the measure of angle CBD is 5(7x + 15) degrees, then what is the value of x. (Angle CDB is 180)
svetoff [14.1K]

Answer:

\huge\boxed{\sf x = 3 }

Step-by-step explanation:

<u>If the measure of :</u>

∠CBD = 5 ( 7x + 15 )

<u>Also,</u>

∠CBD = 180°

<u>Then,</u>

5 (7x + 15) = 180

35x + 75 = 180

Subtract 75 to both sides

35x = 180 - 75

35x = 105

Divide both sides by 35

x = 105 / 35

x = 3

\rule[225]{225}{2}

Hope this helped!
