Answer:
Chocolate Chips cost $2.25 and Walnuts cost $3.25 per pound each
Step-by-step explanatChocion:
Let x = cost of pounds of chocolate chip cookies and y = cost of pounds of walnuts.
From the question, we get 5x+3y = 21 and 2x+6y = 24. To solve the equation, we use substitution. From the first equation, we get y = (21-5x)/3. We substitute the y into the second equation to get 2x + 6(21-5x)/3 = 24. This turns out to be 2x+(42-10x) = 24. Adding like terms you should get 42-8x = 24. Solving for x, x = $2.25 per pound. Plugging this into the first equation, we get 5(2.25)+3y = 21. Solving for y, we get $3.25 per pound of walnuts. If we plug in the numbers into the 2 equations, we will get the right total.
Jonathon should plan on spending $182.50.
Because 65+45=110 guests.
45 guests wanted crab cakes and they cost $2.25 each so 45 x 2.25= $101.25
65 guests wanted chicken kabobs and they cost $1.25 each so 65 x 1.25= $81.25
$101.25+$81.25= $182.50
with $17.50 left over.
A
rational number is a number which can be expressed as a fraction whose
numerator and denominator are both integers and whose denominator is not equal
to zero. Rational numbers include all integers, fractions, mixed numbers, and
some decimal numbers.
Note : All terminating and repeating decimal
numbers are rational numbers because those numbers can be expressed as a
fraction. On the other hand, a non repeating number and non terminating
decimal, like square root of 2, is an irrational number.
Multiply by 1 to eliminate two decimal places.

Answer:
The graph of the line that contains the point
with a slope of 2/3.
Step-by-step explanation:
As the line contains the point (-3, 1) with a slop 2/3
Given the slop-intercept form of the line equation
y = mx+b
Here,
Substituting the values in the slop-intercept form of the line equation
![y = mx+b](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb)
![1 = \frac{2}{3} (-3) + b](https://tex.z-dn.net/?f=1%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20%28-3%29%20%2B%20b)
![1 =- 2 + b](https://tex.z-dn.net/?f=1%20%3D-%202%20%2B%20b)
switching sides
![-2+b=1](https://tex.z-dn.net/?f=-2%2Bb%3D1)
![b=3](https://tex.z-dn.net/?f=b%3D3)
Now Substituting the value of
in the slop-intercept form of the line equation
![y = mx+b](https://tex.z-dn.net/?f=y%20%3D%20mx%2Bb)
![y=\frac{2}{3} x+3](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7D%20x%2B3)
Hence, the line of the equation will be: ![y=\frac{2}{3} x+3](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7D%20x%2B3)
Therefore, the graph of the line that contains the point
with a slope of 2/3.
