Here I'll help you:
In order to solve the problem we must take the "x" to one side, and the numbers to the other side. When we move the three to the other side of the equation, we must change the "negative" to a positive [if it were to be positive, we'd make it negative.]
Now we have: 5 + 3 = 15x
Let's solve the left side.
We'll have: 8 = 15x
Now we have to divide both sides by 15.
Our answer would be:
.5333333 = 1x
In short, your answer is: X = 5.333333
Answer:
252
Step-by-step explanation:
9 x 20 = 180
9 x 28 = 252
The sum of 3.0478 and 4.92 is 
, which have 5 significant digits.
<u>Step-by-step explanation:</u>
We have , 
and 
. The significant digits of a number are digits that includes all digits except:
- All leading zeros. For example, "013" has two significant figures: 1 and 3;
- Trailing zeros when they are merely placeholders to indicate the scale of the number and ,
- Spurious digits introduced, for example, by calculations carried out to greater precision than that of the original data, or measurements reported to a greater precision than the equipment supports.
Here and with significant digit rules 
. Now, Sum of both numbers = 
⇒Sum of both numbers = 
⇒Sum of both numbers =
∴ The sum of 3.0478 and 4.92 is , which have 5 significant digits.
Step-by-step explanation:
The value of x when f(x) = -4 is 3
<h3>How to solve the function?</h3>
The function is given as:
f(x) = -3x + 5
When f(x) = -4, we have:
-4 = -3x + 5
Subtract 5 from both sides
-3x = -9
Divide both sides by -3
x = 3
Hence, the value of x when f(x) = -4 is 3
