Answer:
this would be 12/6+(-1/6)
Step-by-step explanation:
if you want to solve it would be 11/6, or "1 5/6ths"
we need to first find the common denominator, which is 6, but since we multiplied the bottom by 2, we multiply the top by 2. next we just subtract the values, and i put the 1 because there is only one "6" that goes in to the bottom ,and 5 is left over.

Linda's recipe makes 20 chocolate candies.
She uses:
1 cup cream
3 cups dark chocolate
Using Linda's recipe:
2. How much dark chocolate will you need to make 60 candies? Write proportion and solve.
9514 1404 393
Answer:
9 cups
Step-by-step explanation:
If x represents the number of cups of dark chocolate needed for 60 candies, the proportion can be ...
cups/candies = 3/20 = x/60
Multiplying by 60 gives ...
x = 60(3/20) = 9
You need 9 cups of chocolate for 60 candies.
Find the solutions to (x + 4)2 = 25.
Check all that apply.
Answer:
x= 17/2 is the correct answer

Suppose a certain traffic light shows a red light for 50 seconds, a green light for 50 seconds, and a yellow light for 5 seconds. If you look at this light at some randomly selected instant, what is the probability you will see a yellow or green light?
Answer:
[tex]P(Yellow\ or\ Green) = 0.524[/tex]
Step-by-step explanation:
Given
[tex]Yellow = 5\ seconds[/tex]
[tex]Green = 50\ seconds[/tex]
[tex]Red = 50\ seconds[/tex]
Required
Determine the probability of Green or Yellow
First, we need to determine the total time
[tex]Total = 50 + 50 + 5[/tex]
[tex]Total = 105\ seconds[/tex]
Next, is to determine the required probability
This is calculated as follows:
[tex]P(Yellow\ or\ Green) = P(Yellow) + P(Green)[/tex]
[tex]P(Yellow\ or\ Green) = \frac{n(Yellow)}{Total} + \frac{n(Green)}{Total}[/tex]
[tex]P(Yellow\ or\ Green) = \frac{5}{105} + \frac{50}{105}[/tex]
[tex]P(Yellow\ or\ Green) = \frac{5 + 50}{105}[/tex]
[tex]P(Yellow\ or\ Green) = \frac{55}{105}[/tex]
[tex]P(Yellow\ or\ Green) = 0.52380952381[/tex]
[tex]P(Yellow\ or\ Green) = 0.524[/tex] -- Approximated
geometric mean between 2 and 2/9
Answer:
2/3.
Step-by-step explanation:
Geometric mean = √(2 * 2/9)
= √(4/9)
= 2/3.
The geometric mean between 2 and 2/9 is 2/3.
What is mean?We can define the mean of the given data set as the average of all the
numbers. Mathematically, we can write mean as -
M = ∑x{i}/n
Given is to find the geometric mean between 2 and 2/9.
The general formula used to calculate the geometric mean is -
[tex]$\left(\prod _{i=1}^{n}x_{i}\right)^{\frac {1}{n}}={\sqrt[{n}]{x_{1}x_{2}\cdots x_{n}}}[/tex]
We can write the geometric mean between 2 and 2/9 as -
GM = √(2 x 2/9)
GM = √(4/9)
GM = √4/√9
GM = 2/3
Therefore, the geometric mean between 2 and 2/9 is 2/3.

Jason is having a pizza party for
his birthday. If he is having 20
friends over and they each eat 3/8
Of a pizza, how many pizzas should
he buy for the party?
Answer:
8 pizzas
Step-by-step explanation:
If each of the 20 people eats 3/8 of pizza, to calculate the total number of pizzas needed, multiply 20 by 3/8 and round up to the nearest whole number.
[tex]\sf total \ number \ of \ pizzas=20 \times\dfrac38[/tex]
[tex]=\dfrac{20 \times3}8[/tex]
[tex]=\dfrac{60}8[/tex]
[tex]=\dfrac{15}2[/tex]

Therefore, he should buy 8 pizzas for the party.
Tina is planning to fence in an area for her dog. She wants to create a rectangular area of 1,600 square feet for her pet and can afford to purchase 160 feet of fence. In two or more complete sentences, explain the algebraic model, calculations and reasoning necessary to determine the dimensions of the rectangular area.
The dimensions of the rectangular area of Tina's fence is 40 ft by 40 ft
Area of a rectangle:area = lwwhere
l = length
w = width
She wants to create a rectangular area of 1,600 square feet for her pet . Therefore,
area = 1600 ft²lw = 1600
Therefore,
perimeter = 160 ft
Then,
perimeter of rectangle = 2(l + w)
160 = 2(l + w)
l + w = 80
Let's combine the equations
lw = 1600
l + w = 80
l = 80 - w
Therefore,
w(80 - w) = 1600
80w - w² = 1600
Therefore,
w² - 80w + 1600 = 0
w² - 40w - 40w + 1600 = 0
w(w - 40) - 40(w - 40) = 0
(w - 40)(w - 40) = 0
w = 40 or 40
Therefore, the dimensions can be calculated as follows:
lw = 1600
40l = 1600
l = 1600 / 40
l = 40 ft
Therefore, the dimensions are 40ft by 40 ft

I didn't understand the questionFind the equation of the line that passes through (3,1) and is parallel to y=3−2x. Leave your answer in the form y=mx+c
How do I find the equation of the line y=mx + C, passing through the points M (-2, -3) and T (3, 7)?
How do I find the equation of the line y=mx + C, passing through the points M (-2, -3) and T (3, 7)?
A2A
y = mx + C is often called slope-intercept form.
There are two pieces of information you will need to solve for. #1: The slope, which is m, and #2: the y-intercept, which is C (incidentally I learned this as y = mx + b, instead of y = mx + C, but that is a trivial detail)
Step #1 Find the slope. use the formula slope = (y₂ - y₁)/(x₂ - x₁) => (7 - -3)/3 - -2) = 10/5 = 2. m=2
Step #2 Find the y-intercept. Solve for y = mx + C when x is 2 and x = -2 and y = -3 -3 = 2(-2) + C => -3 = -4 + C add 4 to both sides, 1 = C
Equation: y = 2x + 1.
Check: x = 3 => y = 2(3) + 1 => y = 6 + 1 => y = 7 => (3, 7)
Check: x = -2 => y = 2(-2) + 1 => y = -4 + 1 => y = -3 => (-2, -3)
