I think the answer is B.78Degrees
Start off by combining like terms on the LHS (the terms with x in them).
So we get

Replacing this result with what we had before on the LHS, we get

⇒Solve for x (divide both sides

)
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by

⇒

⇒

***This is a proper fraction
Step-by-step explanation:
80:100=x:20
x=80×20/100=16
Answer:
1100
2200
Step-by-step explanation:
Since speed is constant, the distance is proportional to the time. We notice that the number in the second column is 1650/3 = 550 times the number in the first column, so the two missing numbers are ...
2 × 550 = 1100
4 × 550 = 2200
Hey! the answer is…
3/2c^3-1/12c^2 -4-c^4-c
i also added a picture of how the answer should be written just in case you don’t understand what’s above!
