Answer:
the answer to your question will be D, 20%
The equation is 51 = x + 120 × 0.30 that can find the monthly base fee charged by Chitchat wireless.
The equation representing the scenario will be formed through following components.
Total bill = monthly base fee + number of minutes × cost per minute
In the above mentioned equation, let us assume the monthly base fee to be x. Now, keep the values in formula to find the value of x.
51 = x + 120 × 0.30
Performing multiplication on Right Hand Side of the equation
51 = x + 36
Rewriting the equation according to x
x = 51 - 36
Performing subtraction on Right Hand Side of the equation
x = 15
Thus, the monthly base fee is $15.

Answer:
15 boys and 20 girls
Step-by-step explanation:
1. Since we cant simplify 3:4 we will leave it just like that.
2. 3x+4x=35
3. We add them both to give us 7x=35
4. We divide by 7 to get x by itself which results in 35/7=5.
x=5
5. Now we found x we can create 2 seperate soulutions:
3(5)=
and 4(5)=
Therefore there are 15 boys and 20 girls in the class. This makes sense because 15/20 reduced is 3 over 4.
