Answer:
17
Step-by-step explanation:
because of the kind of angle it is, the two equations are equal. So, put the equations equal to each other and solve:
x+35=3x+1
combine like terms (by subtracting)
2x=34
isolate x by dividing by 2
x=17

Answer: 45%
Step-by-step explanation: There's 9 people over the age of 14. And 9 divided by the total number, 20, gives you 0.45. 0.45 multiplied by 100 is 45.
All real solutions
Everything cancels out once you multiply the top equation by two.
0 = 0 which means all real answers.
I hoping you meant question 3. Good luck!
Answer:
Look below
Step-by-step explanation:
So I will use an example to try and show you how to do this.
If we have
, we know that we don't have like denominators. We can change this by finding one. All we need to do is multiply our denominators. So in our example, that would be
. Our new denominator would be 6. So now we would have
which isn't the same as our old equation. That is because we haven't multiplied our top numbers yet. To do this, we need to multiply the top number by the opposite denominator like so,
.
So our first fraction was

We then multiplied the whole fraction by the opposite denominator
