Answer:
Step-by-step explanation:
You have the equation .
Then, to solve for the variable from the equation you need:
Make the subtraction of the right side of the equation:
(As the denominators are 1 and , the least common denominator is )
Multiply to both sides:
Add to both sides:
And finally divide both sides by :
Answer: It will take Damon 6 weeks to save the money he needs to buy the snowboard
Step-by-step explanation:
First, let's see what the problem is giving us:
-The variable X will represent the number of weeks it will take Damon to save the money he needs.
- Damon has $40
- Damon is going to safe $20 weekly
- The snowboard costs $160
Therefor:
Our equation will be: $40 + $20X = $160
Step 1
We need to isolate the variable by subtracting in both sides of the equation 40 in order to maintain the equality.
40 - 40 + 20X = 160 - 40
This will let us with 20X = 120
Step 2
We have to isolate the variable again, but this time (because the variable is being multiplied by 20) we have to divide on both sides of the equation.
20X/20 = 120/20
Therefore: X=6

<u><em>hi there user! Looks like your looking for help, so Mizuki came here to help you!</em></u>
the answer is:
<em>m is 2/3</em>
The whole work I did:
m + 4 ÷ 3 = 2
m + 4/3 = 2
m + 4/3 - 4/3 = 2 - 4/3
m = 6/3 - 4/3
m = 2/3
Anyways hope this helped! qwq
Answer:
x = 10
Explanation:
Note the following rules before we begin:
2 ln(a) = ln (a²)
ln (a) + ln (b) = ln (ab)
Now, for the given:
ln(20) + ln(5) = 2 ln(x)
ln(20*5) = ln(x²)
ln(100) = ln(x²)
This means that:
100 = x²
Therefore:
either x = 10 .........> acceped
or x = -10 .........> rejected as no negatives are allowed within ln functions
Hope this helps :)
