Answer:
x=30
Step-by-step explanation:
4x+2x=180
6x=180
x=30
The equation that represents the given problem is (n-30) + n = 210. The correct option is the first option (n-30) + n = 210
<h3>Linear equation</h3>
From the question, we are to write an equation for the given problem
From the given information,
n = Tom's weight in pounds
If Jim weighs 30 pounds less than Tom
Then,
Jim weighs (n - 30)
Thus,
The sum of their weight is
(n-30) + n
∴ (n-30) + n = 210
Hence, the equation that represents the given problem is (n-30) + n = 210. The correct option is the first option (n-30) + n = 210

15%=3
5%=1
5(20)=100
1(20)=20
So, there are 20 students in the class.
Unit rate because unit is referring to one so for example for every unit, there are 6 apples. The unit in the case would be a box
