Answer:
Step-by-step explanation:
Since you're only interested in x, you can use the first equation to write an expression for y that can be substituted into the second equation.
.. y = k -x
.. 2x +3(k -x) = k +1
.. -x +3k = k +1 . . . . . collect terms
.. 2k -1 -x = 0 . . . . . . subtract k+1
.. 2k -1 = x . . . . . . . . .add x
The 3rd selection is appropriate.
I'm pretty sure you already solved this by now, but I'll say the answer anyway. This problem has already been solved by another as a verified answer.
This is the concept of financial algebra, we are required to calculate the value of stock ABC which follows the model given by:
y=12.21x+37.42
given that x=62 days,
the value of th estock after 62 days will be given by:
y=12.21(62)+37.42
y=757.02+37.42
y=794.44
ABC will be worth $794.44

Answer:
4
Step-by-step explanation:
The distributive property does not appear to be involved in this question.
Let n represent the number of Noah's pencils. Then Andrew's total is ...
3n +5 = 17
3n = 12 . . . . . subtract 5 from both sides
n = 4 . . . . . . divide both sides by 3
Noah has 4 pencils.
So, the first blank is for what kind of angle it is: acute, obtuse, reflex, straight, or right. The second blank is for what the measure of the angle is. You can find that out by looking at the protractor. It should tell you what the measure of the angle is. You can read the protractor by looking at the numbers. The numbers are the degrees of incline the angle measures, which is what you're looking for.
