Answer:
11.25 pounds of chicken need to be bought
Step-by-step explanation:
Per person will eat:
3/8 * 2 = 3/4 = 0.75 pound
So if one person will eat 0.75 pound.
15 people will eat 15 * 0.75 = 11.25 pounds

3x – 6y = 3(x - 2y)?
1. associative
2.Commutative
3.distributive
4.closure
Answer:
3. Distributive
Step-by-step explanation:
In the equation 3(x - 2y) if you distribute the 3 to the x and the -2 you would get 3x-6y.
The property illustrated in the equation is 3)Distributive
What is the Distributive property?Distributive law, also called distributive property, in mathematics, the law relating the operations of multiplication and addition, stated symbolically as a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac.
Given here, 3x-6y=3(x-2y)
Thus clearly 3 is distributed over x and 2y
Hence, The property illustrated in the equation is 3)Distributive

How many teaspoons are in 200 milliliters? 1 tsp = 5 ml 200 mL = [?] tsp
Answer: 40
Step-by-step explanation:
using dimensional analysis ( you might not have learned this yet, but it's basically multiplying things to cancel out units)...
200 ml * (1 tsp/ 5 ml) = 40 tsp
200 milliliters is equal to 40 teaspoons.
Here, we have,
given that,
1 tsp = 5 ml
so, we get,
If 1 teaspoon (tsp) is equal to 5 milliliters (ml),
then to find how many teaspoons are in 200 milliliters (mL),
we have to divide 200 by 5:
so, we get,
200 mL / 5 mL/tsp
= 40 teaspoons (tsp)
i.e. 200 ml * (1 tsp/ 5 ml) = 40 tsp
So, 200 milliliters is equal to 40 teaspoons.

Prove that Triangle abc and Triangle edc are similar
The corresponding sides have equal ratios, so the triangles are similar triangles.
From the question, we have:
In triangle ABC, AB = 3, BC = 5 and AC = 4
In triangle EDC, ED = 9, DC = 15 and EC = 12
For the triangles to be similar, then the corresponding sides must have an equivalent ratio.
This is calculated as:
[tex]\mathbf{Ratio = \frac{ED}{AB} = \frac{DC}{BC} = \frac{EC}{AC}}[/tex]
So, we have:
[tex]\mathbf{Ratio = \frac{9}{3} = \frac{15}{5} = \frac{12}{4}}[/tex]
[tex]\mathbf{Ratio =3 = 3 = 3}[/tex]
[tex]\mathbf{Ratio =3}[/tex]
Because the corresponding sides have equal ratios, then the triangles are similar.

d. I don't know.
5x+2y=29
x+4y =13
i don’t know that answer
Answer:
x=71/9, y= -47/9
Step-by-step explanation:
5x+2y=29
x+4y=13 subtract 4y from both sides
x= -4y+13 substitute on the first one
5( -4y+13) + 2y = 29 distribute in parenthesis
-20y - 65 +2y =29 add 65 to both sides
-20y +2y = 29+65 combine like terms
-18y = 94 divide by -18 both sides
y= 94/-18= -47/9
substitute y =-47/9 in x=-4y+13
x=-4(-47/9)+13=(188/9)+13=188+117/9=71/9

x –12 = -8x + 6 a.x = 2 b.x = -2 c.x = 3 d.x = -3
Answer:
(a) x = 2
Step-by-step explanation:
x - 12 = -8x + 6
First, move all the like terms to one side of the equation. We will move all the x's to the left, and the rest to the right in this equation. (Don't forget to pay attention to the signs of the numbers as you move them over the equal sign.)
x - 12 + 8x = 6
x + 8x = 6 + 12
9x = 18
Next, solve for x by isolating it to one side of the equation. Here, we'll have to divide 18 by 9 (do the opposite of what 9 is doing with x; instead of multiplying it with 18 like it currently is with x, divide 18 by it.)
x = [tex]\frac{18}{9}[/tex]
x = 2
Therefore, your answer is (a), since x = 2.
I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!
Consider the graph of the function f(x)=10^x.
Using graph, the value of g(x) = 8 and the y- intercept at the point (0,-1).
What is graph?A graph is a "mathematical representation of a network and it describes relationship between lines and points".
According to the question,
f(x) = [tex]10^x[/tex]
g(x) = -4f(x) +12
g(x) = -4 (10ˣ) +12
The graph intersect at y-axis then x-coordinate should be zero.
Let take any two points on y-axis (0, 1) and substitute g(0) = -4 (10⁰) + 12
= 8
Hence, the value of g(x) = 8 and the y- intercept at the point (0,-1).
