You have to solve for F so you need to get it by itself which means it would look like:
9/5C+32=F
Then you plug in 33 for C and solve. When you round to the nearest whole number, you get D. 91
You are trying to solve for k (get k by itself)
-5k - 19 = 5 - 13k Add 19 on both sides
-5k - 19 + 19 = 5 - 13k + 19
-5k = 24 - 13k Add 13k on both sides
-5k + 13k = 24 - 13k + 13k
8k = 24 Divide 8 on both sides
k = 3
Answer:
4/5
Step-by-step explanation:
1/5 + 3/5 = 4/5
when adding fractions you don't add the denominators

when the slope of the points is undefined, is a flag that is a vertical line.
