Answer:

b=\frac{a+2c}{3}

Step-by-step explanation:

We have been given an equation a=3b-2c. We are supposed to solve the given equation for b.

First of all, we will switch sides of the given equation as:

3b-2c=a

Let us add 2c on both sides:

3b-2c+2c=a+2c

3b=a+2c

Divide both sides by 3:

\frac{3b}{3}=\frac{a+2c}{3}

b=\frac{a+2c}{3}

Therefore, our required equation wold be b=\frac{a+2c}{3}.

M+4+2-7m+6 I need to find how many’s terms are in it and what are the terms
madreJ [45]

Answer:

5 terms:  m, 4, 2, -7m, 6 are the terms in question.

Step-by-step explanation:

Note that terms here are separated from one another by either + or - signs.

m + 4 consists of two terms, since m and 4 are separated by the + operator.

2 - 7m are separated by the - operator, and so there are two terms here.

Completing the counting procedure, we get:

m (first term) + 4 (second term) + 2 (third term -7m (fourth term) + 6 (fifth term).

So, if we do NOT combine like terms, we have five (5) terms altogether.

If we DO combine like terms, we end up with two (2) terms:

m -7m + 4 + 2 + 6, or -6m + 12, or two (2) terms.

The conversion of 9.204 to a mixed number will be 9 51/250.

<h3>How to illustrate the information?</h3>

It should be noted that converting decimal to mixed numbers simply means changing them to whole numbers and fractions.

Therefore, 9.204 will be:

= 9 204/1000

= 9 51/250

The percentage equivalent of 3 7/8 will be:

= (3 × 100) + (7/8 × 100)

= 300 + 87.5

= 387.5%

Dividing 72 in the ratio 2:3:4 will be:

= 2/9 × 72 = 16

= 3/9 × 72 = 24

= 4/9 × 72 = 32
