Help ! Please ! If a/2 - b/3=1 , what is 2a+3v in terms of b?
ArbitrLikvidat [17]
A/2-b/3=1  solve for a, add b/3 to both sides

a/2=1+b/3 which is equal to

a/2=(3+b)/3  multiply both sides by 2

a=(6+2b)/3  now you can substitute this into 2a+3b giving you:

2(6+2b)/3 + 3b which is equal to

(12+4b+9b)/3

(13b+12)/3

15 balls are in bag of red and blue balls if 6 is red how many red balls must be added to bag so that probability is 2÷3​
Brut [27]

Answer: 12 red balls must be added

Step-by-step explanation:

Starting out with 15 balls, 6 red implies 9 blue. If blue remains 9, then we expect red to be 18 for a probability at 2/3. 18-6 = 12

Are this two triangles similar?
Alex73 [517]
<h3>Answer:   </h3><h3>Yes, the triangles are similar</h3><h3>AC = 6</h3>

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

Explanation:

Focus on triangle ABC. Let's find the missing angle

A+B+C = 180

113+B+22 = 180

B+135 = 180

B = 180-135

B = 45

Between the triangles, have two pairs of angles that are congruent

A = D = 113

B = E = 45

Which is enough to prove the triangles are similar through the angle angle (AA) similarity theorem. This must mean that C = F = 22

Since we have A pair with D, and B pair with E, this means that \triangle ABC \sim  \triangle DE F

The order of the letters is important so we know how the angles pair up. The first letters pair up together, the second letters pair up, and so on.

Consequently, this means sides BC and EF pair up and AC and DF pair up

We can then say...

BC/EF = AC/DF

18/12 = x/4

18*4 = 12*x

72 = 12x

12x = 72

x = 72/12

x = 6

AC = 6
