Nari says, "The sum of 10 and one-third of a number is 25." She uses the bar model to write an equation to represent her
Mariana [72]

Answer:

25=10+\frac{1}{3}n.

Step-by-step explanation:

It is given that the sum of 10 and one-third of a number  is 25.

Let as consider n be the unknown number.

One-third of a number =\frac{1}{3}n

Sum of 10 and one-third of a number =10+\frac{1}{3}n

The sum of 10 and one-third of a number  is 25. It can be written as

25=10+\frac{1}{3}n

Therefore, the required equation is 25=10+\frac{1}{3}n.

Solve the equation to find the value of m and n.<br> 2m + 3n = -5<br> 5m + 3n = 1
Leokris [45]

Answer:

m = 2, n = - 3

Step-by-step explanation:

Given the 2 equations

2m + 3n = - 5 → (1)

5m + 3n = 1 → (2)

Subtract (2) from (1) term by term to eliminate n

2m - 5m = - 5 - 1

- 3m = - 6 ( divide both sides by - 3 )

m = 2

Substitute m = 2 into either of the 2 equations and solve for n

Substituting into (1)

2(2) + 3n = - 5

4 + 3n = - 5 ( subtract 4 from both sides )

3n = - 9 ( divide both sides by 3 )

n = - 3
