Answer:
Answer: 25 guests is 2.5 times more than 10
Multiply each order by 2.5
Chicken = 16 x 2.5 = 40
Lasagna = 7 x 2.5 = 17.5 , round to 18
Deli meat = 1.8 x 2.5 = 4.5, round to 5
Sliced cheese = 15 x 2.5 = 37.5, round to 38
Buns = 1 x 2.5 = 2.5, round to 3
Potato salad = 2 x 2.5 = 5

Answer:
Shorts: 38
T-Shirts: 152
Step-by-Step
The number of shorts sold can be written as (s) and the number of t-shirts sold can be written as (t)
We know that shirts are $2, and shorts are $4, and the total sales were $456, so the following equation can help us to find the answer, since if we add up the money from shirts and the money from shorts we’ll get the total sales.
4s + 2t = 456
Next, we know that shirts were bought 4 <em>times </em> <em>more </em>than shorts, so we can also write the following equation:
4s = t
Now, since we have a defined “value” for t
(<em>t = 4s), </em>we can substitute this value into the first equation.
4s+ 2(4s) = 456,
4s + 8s = 456,
12s = 456
s = 38
Now we can use this value in the second equation, and solve for t
4s = t
4(38) = t
152 = t
Answer:
The multiplication property of equality states that if two values a and b are equal when you multiply each by the same value c, the products are equal.
Step-by-step explanation:
Multiplication property of equality:
- It states that multiplying both sides of the the equation with the same constant or number then the truth value of the equation does not change.
- That is the equality still holds true.
So, if
![a = b](https://tex.z-dn.net/?f=a%20%3D%20b)
Then, we can write by multiplication property of equality
![a=b\\\Rightarrow a\times c = b \times c\\\Rightarrow ac = bc](https://tex.z-dn.net/?f=a%3Db%5C%5C%5CRightarrow%20a%5Ctimes%20c%20%3D%20b%20%5Ctimes%20c%5C%5C%5CRightarrow%20ac%20%3D%20bc)
Thus, the correct answer is
The multiplication property of equality states that if two values a and b are equal when you multiply each by the same value c, the products are equal.
Answer:
x = 3 x = 7 Okay well I got C. f(x) = x2 - 10x + 21 I got it because u subtract and add at the last part.

Answer:
1/2
Step-by-step explanation:
Find two easy-to work with points
-3,2 and -1,3
slope, m = (y1-y2 ) / ( x1-x2)
(2-3) / ( -3 - -1) = -1/(-2) = 1/2
( it does not matter which point you select as x1 ,y1 or x2, y2 )
