Solve the equation. \qquad r - 14 = 23r−14=23

Nesterboy [21]

Answer: $r=37$

Step-by-step explanation:

For this exercise it is important to remember that:

1. The Addition property of equality states that:

If $a=b$ , then $a+c=b+c$

2. The Subtraction property of equality states the following:

If $a=b$ , then $a-c=b-c$

3. The Division property of equality states that:

If $a=b$ , then $\frac{a}{c}=\frac{b}{c}$

4. The Multiplication property of equality states the following:

If $a=b$ , then $a*c=b*c$

Then, having the following equation given in the exercise:

$r-14=23$

You need to solve for the variable "r" in order to find its value.

In order to solve for "r", you must apply the Addition property of equality adding 14 to both sides of the equation.

Therefore, you get the following solution:

$r-14+(14)=23+(14)\\\\r=37$

Mr. Lynch bought some oranges and pears.

Illusion [34]

Answer:

11: 12

Step-by-step explanation:

Let the number of oranges and pears Mr Lynch have initially be x and p respectively.

x -10= ½p

2(x -10)= p

p= 2x -20 -----(1)

Since Mr Lynch did not give any pears away, the number of pears at the end is the initial number of pears.

p= 24

Substitute p= 24 into (1):

2x -20= 24

2x= 24 +20 (+20 on both sides)

2x= 44

x= 44 ÷2

x= 22

$\frac{x}{p} = \frac{22}{24}$

$\frac{x}{p} = \frac{11}{12}$

Thus the ratio of orange to pears in the beginning is 11: 12.
