Option 1: 6a = 420 requires division property of equality to be solved
Step-by-step explanation:
Solving an equation means to find the value of a variable by isolating the variable on one side of the equation.
We will see all the options one by one.
<u>Option 1:</u>
![6a = 420](https://tex.z-dn.net/?f=6a%20%3D%20420)
In this option, 6 is multiplied with the variable so we have to divide the whole equation by 6 to find the value of a.
So we will use "Division property of Equality"
Dividing both sides by 6
![\frac{6a}{6} = \frac{420}{6}\\a=70](https://tex.z-dn.net/?f=%5Cfrac%7B6a%7D%7B6%7D%20%3D%20%5Cfrac%7B420%7D%7B6%7D%5C%5Ca%3D70)
Hence,
Option 1: 6a = 420 requires division property of equality to be solved

Answer:
ummmm click on the one u r on
Step-by-step explanation:
I think the answer is d. -11
Explanation:
Replace the variable x with 3 in the expression.
f(3)=-2•3-5
Multiply -2 by 3
f(3)=-6 -5
Subtract 5 from -6
f(3)= -11
Then the answer should be -11.
