Using the properties of parallel lines, then

x + 44 = 83 ( subtract 44 from both sides )

x = 39

If the temperature started at 8 degrees celcius at Noon and it dropped 10 degrees over the next 5 hours

leonid [27]

Answer:

The answer is " $\bold{2^{\circ}\ C}$ "

Step-by-step explanation:

Given:

noon temperature $= 8^{\circ} C$

Total change in next 5 hours $= 10^{\circ} C$

Calculating the final temperature:

$\text{final temperature = noon temperature - changes in 5 hours}$

$= 8^{\circ} -10^{\circ} \\\\=- 2^{\circ} \ C$

Erica had 6 coins in her coin collection. She goes to a coin show and buys some more coins. How many coins does she have now?

goldfiish [28.3K]

Answer:

6+x with x equalling the amount of coins bought if that is what you were looking for

Step-by-step explanation:

if you want to make and equation out of this you don't know the amount of coins she bought so you use a variable (x) to replace that unknown number then since it says she bought more she is adding more to her collection which means it would be an addition problem, leaving you with 6+x for your final answer
