Answer:
1:4 ratio
Step-by-step explanation:
The Answer is a 1:4 ratio because 1/5 of 10 is 2 and 4/5 of 10 is 8 so the ratio would look like 2:8. You would then simplify 2:8 to 1:4.
Ratio of red to blue marbles is 1:5
An equation is used to show the relationship between two or more numbers and variables.
10 marbles in a bag 1/5 are red and the others are blue.
number of red marbles = 1/5 * 10 = 2
number of blue marbles = 10 - 2 = 8
Ratio of red to blue marbles is 2:8 = 1:5

Naomi is buying bagels for a family gathering. Each bagel costs $1.25. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
Answer:
total cost = 1.50x
Step-by-step explanation:
Given cost of 1 bagel = $1.25
Let the number of bagels purchased by x
cost of x bagels = cost of 1 bagel *x
cost of x bagels = 1.50*x
Thus,
relationship between bagels and total cost is as shown below
total cost = 1.50x
where x is the number of bagels purchased.
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is N(x) = 1.25x.
So N(4) =5, meaning 4 bagels will cost 5 dollars.

-11 + 9(x + 1) = 4(1 + 3x) - 3
Answer:
x = -1
Step-by-step explanation:
-11 + 9(x+1) = 4(1+3x) - 3
9x + 9 - 11 = 12x + 4 -3
9x - 2 = 12x +1
-2 = 3x + 1
-3 = 3x
x = -1

Ecuación 2:
10x + 20y = 8000
ayudaaa
Answer:
y = 300
x = 200
Step-by-step explanation:
Esta pregunta parece incompleta, parece que acá tenemos un sistema de ecuaciones:
x + y = 500
10*x + 20*y = 8000
Estas ecuaciones tienen que resolverse en conjunto, y de acá sacaremos un par de puntos (x, y) que son solución para ambas ecuaciones.
El primer paso para resolver esto es aislar una variable en una de las ecuaciones, en este caso podemos aislar x en la primera ecuación y así obtener:
x = 500 - y.
Ahora podemos reemplazar eso en la segunda ecuación y obtener:
10*(500 - y) + 20*y = 8000.
Ahora resolvemos esto para y.
5000 - 10*y + 20*y = 8000
10*y = 8000 - 5000 = 3000
y = 3000/10 = 300.
Y sabíamos que:
x = 500 - y = 500 - 300 = 200
Entonces la solución es:
y = 300
x = 200

The center of a circle lies on the line y=6x+2 and is tangent to the X axis at (-2,0) what is the equation of the circle in standard form?
Answer:
(x+2)^2 + (y+10)^2 = 100
Step-by-step explanation:
y = 6x + 2
Z(-2,0)
x = -2
y = 6 x (-2) + 2
y = -12 + 2
y = -10
M(-2, -10)
r = 0 - (-10) = 10
(x + 2)^2 + (y + 10)^2 = 100

Step-by-step explanation:
Given 2 sides, then let x be the third side and
difference of 2 sides < x < sum of 2 sides , that is
8 - 4 < x < 8 + 4
4 < x < 12

Sydney asked her friends to write down the number of hours they practice their instruments each week. The data is shown.
1, 6, 6, 5, 2, 2, 0,5,6,7
What is the median of the data?
Answer:
5.5
Step-by-step explanation:
if you order the number from least to greatest like this 0,1,2,2,5,5,6,6,6,7 the median is the median number so here the median is 5.5 the reason it is 5.5 is bc the middle number is 5 and 6 and the middle number of that is 5.5
