HELPP, solve for x and y
Triss [41]

Answer:

x=23, y=157

Step-by-step explanation:

23 and x are on equalivent sides of the rhombus so they are equal. To solve for y you have to multiple 23 by 2. Getting 46 you subtract that from 360 to get 314. Dividing 314/2 you get 157.

Luda [366]

Answer:

The answer is 15 Shirts

Step-by-step explanation:

We want to know what x is going to equal that makes the equation the same.

First, I make the euations equal to each other by substituting the y -->

7x + 50 = 10x + 5

Then, I combine my similar terms --> 45 = 3x

After that, I divide by 3 to get x on its own --> \frac{45}{3} =\frac{3x}{3} --> 15 = x

This means that after 15 Shirts are sold, the costs for both companies are the same.

Camila sets up a passcode on her tablet, which allows only nine-digit codes. A spy sneaks a look at Camila's tablet and sees her
laila [671]

Answer:

\frac{1}{10^9} probability the spy is able to unlock the tablet on his first try.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

1 correct password, so D = 1

Total outcomes:

Nine-digit codes.

For each digit, there are 10 possible outcomes. So

T = 10^9

What is the probability the spy is able to unlock the tablet on his first try?

p = \frac{D}{T} = \frac{1}{10^9}

\frac{1}{10^9} probability the spy is able to unlock the tablet on his first try.
