Pam, Wesley, and Diana added up how many miles they walked together.
In one week, they walked 38 miles.
Of those miles, Pam walked 13.
How many miles did Diana walk?
Answer:
12.5
Step-by-step explanation:
If they walked 38 miles and Pam walked 13, subtract 38 from 13, you then get 25. Then, divide that by 2. 25 divided by 2 is 12.5. That is your answer, I believe. Please make this the brainliest answer.

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.

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

Mr. Blanco used 15.75 yards of fabric to make 7 costumes for the school play. How many yards of fabric did he use per costume?
Answer:
2.25 yards per costume
Step-by-step explanation:
if you want to find the unit rate of something put it into a fraction which is also considered dividing. Like if you want to figure out miles per hour or ounces per cup, just divide miles by hour, or divide ounces per cup to get your final answer. In this case divide 15.75 yards of fabric by 7 costumes to get your answer.

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.

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).

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.

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
