Answer:
Step-by-step explanation:
We can divide polynomials by other polynomials by dividing each term by the denominator. Remember, when we divide a variable by itself, we must change the exponent in our answer according to exponent rules.
3:4 = G:B
1:5 = Mr. Smith's class: 7th Grade
2:7= 7th: Middle school
12 girls = 3 units
1 unit = 12/3= 4
Boys = 4x4= 16
<em>Whole class = 28 students</em>
Class : Grade = 1:5 <em> 7 = number of units in Mr. Smith's class</em>
28 = 1 unit
5 units= 28x5= 140 <em>There are 140 kids in the grade</em>
140 = 2 units
1 unit = 140/2= 70
70x7=490
<u><em>There are 490 students in the whole grade</em></u>
The answer too 2 plus 2 is 4 because if you have 2 finger and add 2 more up it will be 4
Hi there! To help you with this, all you have to do is add or subtract the number on the left, depending what the number is to get the variable by itself. If the number is positive with a plus sign, you add. If the number is negative with a minus symbol, you add. With that being said, here are the answers to help you out.
1. B: 8
2. A: 8
3. A: 25
4. C: -1
