A) you must plug in 50 for variable F and solve for C
C=
(50-32)
C=
(18)
C= 10
50 degrees fahrenheit is equal to 10 degrees celsius
B) you must solve the equation for F
C=(F-32)
C/=F-32
C/+32=F
F= C/+32
dividing by a fraction is the same as multiplying buy its reciprocal so it can also be written as
F=
C +32
now you just plug in 50 for the variable C in the new equation
F=(50) +32
F= 90 + 32
F= 122
50 degrees celsius is equal to 122 degrees fahrenheit

We have to draw the model for 42 divide 7 . In order to draw the model we use below steps.
- Draw 7 boxes to represent 7 groups.
- Assume 42 as the number which represents the total of these 7 groups.
- Put a question mark at the first box.
Attached is the model to represents 42 divide 7 .
In the question mark we should put 6. Hence, when we add 6 to 7 times that will be equal to 42.
