We have the expression:
And we need to solve this for x.
Let's solve this expression and then see which of the options is the correct one.
The first step to solve this is that we need for the two sides of the equation to have the same base. (the number 5 on the left side is the base, so we need to also have a 5 as the base on the right side).
We do this by noting that:
We know that 25 is equal to 5 squared (because 5x5 is 25)
So the first step is to substitute 25 for 5 squared:
Since we have the same base on both sides (5), we follow the rule:
• If we have the same base on both sides of an equation, the exponents have to be equal
Thus, the second step to solve is to equal the exponents:
Finally, to solve this equation for x, we just need to add 1 to both sides to get rid of the -1 on the left side:
And the third step is:
As we can see, these three steps are represented in the third option In which we get the same result of x=3.
Answer: x=3
Answer:
5
Step-by-step explanation:
The Apgar score is calculated based on 5 medical criteria:
-Appearance – skin color
-Pulse – heart rate (taken with a stethoscope or by feeling the umbilical cord)
-Grimace – reflex response
-Activity – muscle tone
-Respiration – breathing quality
Each one of the criteria is evaluated on a 0 to 2 scale, once every criteria are measured, the values are added up and the child would have an Apgar score between 0 and 10.
Here:
Apparence = 0
Pulse = 2
Grimace = 1
Activity = 1
Respiration = 1
Total= 2 + 1 + 1 + 1 = 5
100-r=99.52
First, add r to both sides.
100-r+r=99.52+r
And then simplify.
100=99.52+r
Then, subtract 99.52 from both sides.
100-99.52=99.52+r-99.52
And simplify.
0.48=r
So,
r=0.48
The answer is 2 bro how do you not know
