20, you just need to substitute the x value in the equation
(-2)2-7(-2)+10=
=20
Answer:
120 divided by 4 is w
Step-by-step explanation:
Given:
Beginning Balance: 2,447.67
Less: Withdrawal <u> 231.49</u>
Total 2,216.18
Add: Credit to acct <u> 36.61</u>
Ending Balance <u> 2,252.79
</u>The new balance is $2,252.79<u>
</u>
Add 3 on both sides of the equation
3x=0
divide 3 on both sides of the equation
x=0
The Number of boys in the class is: 18
Let's call "g" to the number of girls in the class.
The problem says that there is "w" fewer boys than girls, so we have:
g-w=18
Then, the number of girls in the class is:
g=18+w
Let's call "x" to the total number of studens in the class:
x=g+18
When we substitute g=18+w into x=g+18, we obtain:
x= (18+w)+18
The total number of studens in the class is:
x=w+36
