Evaluate \dfrac13m-1-\dfrac12n

Mathematics
1 answer:
romanna [79]3 years ago
7 0

Answer:

The expression is equal to zero for the given values

Step-by-step explanation:

<u><em>The correct question is</em></u>

Evaluate start fraction, 1, divided by, 3, end fraction, m, minus, 1, minus, start fraction, 1, divided by, 2, end fraction, n   when m=21 and n=12

we have the expression

 \frac{1}{3}m-1-\frac{1}{2}n

we know that

To evaluate the expression substitute the given values of m and n

For m=21 and n=12

\frac{1}{3}(21)-1-\frac{1}{2}(12)

solve the multiplications

7-1-6

solve the subtraction

7-7\\0

therefore

The expression is equal to zero for the given values

Answer: 6 teams

Step by step:

3 people=1 group

3+3=6

6 people taken out of 18

2 groups already

3+6=9

9 out of 18 people taken

3 groups made

9+3=12

12 out of 18 people taken

4 groups made

12+3=15

15 out of 18 people taken

5 groups made

15+3=18

18 out of 18 people taken

Answer: 6 groups made

Short step by step:

18 divided by 3 equals 6

Or

3 times 6 equals 18

I really hope that made sense

Which equation could represent a linear combination of the system?
Ghella [55]

The equation that could represent a linear combination of the system 2/3x + 5/2y = 15 and 4x + 15y = 12 is 0 = 26

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change, slope or gradient

<h3>How to determine the linear combination to the system?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

2/3x + 5/2y = 15

4x + 15y = 12

Multiply the first equation by 6, to eliminate the fractions.

6 * (2/3x + 5/2y = 15)

This gives

4x + 15y = 90

Subtract the equation 4x + 15y = 90 from 4x + 15y = 12

4x - 4x + 15y - 15y = 12 - 90

Evaluate the difference

0 + 0 = -78

Evaluate the sum

0 = -78

The above equation is the same equation as option (b) 0 = 26

This is so because they both represent that the system of equations have no solution

Hence, the equation that could represent a linear combination of the system is 0 = 26
