<h3>The difference between x and 4 is greater than 10.</h3>
This can be written as,
<h3>x - 4 > 10</h3>
<h3>Why?</h3>
✓ We use the operation of subtraction since the terms used is difference. Difference is the result when you subtract numbers.
✓ The symbol for greater than is >. Therefore, you'll have x - 4 > 10 as an answer.
Given the following equation
We want to write an equivalent equation. When you do the same operation on both sides of an equation, the equal sign stays valid. Let's say we multiply both sides by two
This equation is equivalent to the first one. Instead, we could've add three to both sides and then subtract 'y' from both sides.
And all of those equations are equivalent.
Hi,
So we have g(x) = 4√(x). We're looking for g(45). Think of it like this: whatever number is in the place of x in g(x), just place that number AS x.
Therefore, we have :
g(45) = 4√(45) ⇒ (4) × (√(45)) ⇒ (4)(3√(5)) = 12√(5).
-Hope this helps!
Answer:
First blank: 6a
Second blank: 2/3
Third blank: 21.6
Fourth blank: 3.9
Step-by-step explanation:
Basically, all you need to do is distribute the 2/3 to the stuff inside the parentheses. That means in the first blank, write 6a inside since you're multiplying 2/3 and 6a, and then in the second blank you write 2/3 since you're multiplying 2/3 and 9 together.
2/3*6a+2/3*9 = 21.6 is what you should have.
Now, just solve for a.
4a+6 = 21.6
4a=15.6
a=3.9
