First you need to get x on one side of the equation and to do that subtract 2a from both sides.
28 + 2a = 5a + 7
-2a -2a
28=3a+7

Then we need to get a alone by subtracting 7 on both sides.
28=3a+7
-7 -7
21=3a

Finally divide each side by 3 and you should get a = 7. Hope this helps!

A bag contains 5 red marbles, 6 blue marbles and 9 yellow marbles.
lilavasa [31]

Answer:

Step-by-step explanation:

The total number of marbles is 20

Question A

P(Red) = 4/20 = 1/5

P(yellow) = 9/20

P(Red then Yellow) = 1/5 * 9/20 = 9 / 100

Question B

P(B) = 6/20

P(B again) = 5/19 because you  have 1 less total plus 1 less blue.

P(B and B) = 6/20 * 5/19

P(B and B) = 30/ 380 = 3/38

People attending a football game either supported the home team or the visiting team. if 1369 of the people attending supported
Masja [62]

Given the number of the people attending the football game, the percentage supporters for the home team is 37%.

<h3>What is Percentage?</h3>

Percentage is simply number or ratio expressed as a fraction of 100.

It is expressed as;

Percentage = ( Part / Whole ) × 100%

Given the data in the question;

  • Number of home team supporters nH = 1369
  • Number of visting team supporters nV = 2331
  • Percentage of supporters for home team PH = ?

For we determine the total number of people attending the football game;

nT = nH + nV

nT = 1369 + 2331

nT = 3700

Now, using the perecentage formula above, we find the Percentage of supporters for home team PH

Percentage = ( Part / Whole ) × 100%

PH = ( nH/ nT) × 100%

PH = ( 1369/ 3700) × 100%

PH = 0.37 × 100%

PH = 37%

Therefore, given the number of the people attending the football game, the percentage supporters for the home team is 37%.
