Define the variables for each situation. Then write an equation.
7) Jana's age plus 5 equals her sister's age.
J + 5=x
Would this be correct?
8) Andrew's class has 3 more students than Lauren's class.
L + 3=A
Is this correct?
Your equations for both situations are not correct.
For situation 7, where Jana's age plus 5 equals her sister's age:
Let's assume J is Jana's age and S is her sister's age.
Therefore, the correct equation would be J + 5 = S.
For situation 8, where Andrew's class has 3 more students than Lauren's class:
Let's assume L is the number of students in Lauren's class and A is the number of students in Andrew's class.
Therefore, the correct equation would be A = L + 3.
For situation 7, Jana's age plus 5 equals her sister's age.
To define variables and write an equation for this situation, you can represent Jana's age as J and her sister's age as S. The equation would be:
J + 5 = S
For situation 8, Andrew's class has 3 more students than Lauren's class.
To define variables and write an equation for this situation, you can represent Lauren's class size as L and Andrew's class size as A. The equation would be:
L + 3 = A
So, both equations provided are correct representations of the given situations.
9) The bank is 50 feet shorter than the firehouse.
F-50=B
10) The pencils were divided into 6 groups of 2.
P/6=2
Are the above two answers also correct?
