Answer:

266 tickets

Step-by-step explanation:

Ratio of adult tickets to child tickets is 4 : 3

So, if we think of these as "parts", there are 4 parts adult tickets and 3 parts child tickets.

In total there is:

4 + 3 = 7 parts

Now, given 152 adult tickets. If there are 4 parts of adult tickets, how much is each part worth?

152/4 = 38

Total amount of tickets is 7 of these "parts", so total number of tickets is:

38 * 7 = 266 tickets

5(3r+11)=85

raketka [301]

Answer:

r = 2

Step-by-step explanation:

Actually, there are 2 ways to solve this equation.

The first one:

5( 3r + 11) = 85

so here, you have to multiply 5 by ( 3r + 11) and maintain the 85

15r + 55 = 85... now put the like terms together. In other words, just transpose 55 to the other side. 

15r = 85 -55..... remember that the sign of 55 will change from positive to negative 

15r = 30.... now divide both sides by 15

15r/15 = 30/15

 r = 2

The second method :

5 ( 3r + 11) = 85...... divide both sides by 5

5 (3r + 11) / 5 = 85/5

3r + 11 = 17

3 r = 17 - 11

3r = 6 

r = 2

I hope this helps. If you don't quite get it, please go through until you get it. Have a nice day :-)

Kendra owns a restaurant. She charges $3.00 for 2 eggs and one piece of toast, and $1.80 for one egg and one piece of toast. How

Gekata [30.6K]

Ok let me explain it to you like this:
Let the price for one egg be x and the price for one toast be y Then: 3 = 2x+1y,
1.8 = 1x+1y.When we substract, we get x = 1.2 and y = 0.6, so the price for an egg is $1.20 and the price for a toast is $0.60.
Hope this is helpful

Write the standard form of the equation of the line that passes through point at (4,2) and is parallel to whose equation is y=2x

solong [7]

Since the equation is parallel to y=2x-4 that means they have the same slope. Now that you have the slope and fortunately a point, you can solve this by using point slope formula
$y - y1 = m(x - x1)$
Which is what I did on the attached picture and just rearrange it after solving to Ax+By=C/2x-y=6
