Answer:

Question 1. -3 + v5 = 0

Work : -3 + 5v = 0

5v = 3 ( divide )

answer v = 3/5

Question 2. 1 - 7B = -20

work : -7b = -20 - 1

-7b = -21 ( divide )

answer b = 3

question 3 : -k - 5 = 0

work : -k = 5

answer : k = - 5

Question 4 : -1 + 8a = 129

work : 8a = 129 + 1

8a = 130 (divide )

answer a = 65/4

AysviL [449]

The division property of equality should Remus used to solve the given equation and this can be determined by using the given data.

Given :

Equation is $7q = 49$ .

The following steps can be used in order to determine the property that Remus use to solve the given equation:

Step 1 - Write the given equation.

$7q = 49$

Step 2 - The arithmetic operations can be used in order to evaluate the given equation.

Step 3 - Using the division property of equality the value of 'q' can be determined.

$q = \dfrac{49}{7}$

$q = 7$

Therefore, the correct option is A).

The low temperature in degrees Fahrenheit for 5 days was – 5, – 7, – 2, 2, and – 3. What was the average low temperature for tho

sammy [17]

Answer:

-3

Step-by-step explanation:

To find the average of different numbers, first you add them all up. So -5+-7+-2+2+-3+=-15. Then, you divide the sum of all the numbers by the amount of numbers there were. So in this case, there were 5 numbers so we would divide the sum of all of them by 5. So now we do -15/5=-3.

Another example of finding the average of numbers is 15+4+10+9+3+1. So first we add them up and we get 42, then again, we divide by the amount of numbers there are. So we do 40/6 and we get 7, so the average is 7.

I hope this helped.
