DistributiveStep-by-step explanation:
Step 1: Define equation
5(x - 6) + 2 = 7x - 8
Step 2: Solve for x
Distribute 5: 5x - 30 + 2 = 7x - 8Subtract 5x on both sides: -30 + 2 = 2x - 8Add: -28 = 2x - 8Add 8 on both sides: -20 = 2xDivide 2 on both sides: -10 = xRewrite: x = -10Step 3: Check
Plug in x to verify it's a solution.
Substitute: 5(-10 - 6) + 2 = 7(-10) - 8Subtract: 5(-16) + 2 = 7(-10) - 8Multiply: -80 + 2 = -70 - 8Add/Subtract: -78 = -783g-2+7g+8=

how to find the median ?? and explain one problem
Answer:
It's quite simple, let me explain..
Step-by-step explanation:
The median is the middle of a data set, so you would need to find the exact middle of your data set.
If your data set is odd, and has an odd amount of numbers, just get the number exactly in the middle, and that would be your median. But when your data set has an even amount of numbers, it is a bit tricky.
Here's an example:
85, 78, 96, 83, 77
As you can see, this set has an odd amount of numbers, 5 numbers to be exact. The median would be 96 because it is exactly in the middle.
An example of a data set with even numbers would be this:
1, 2, 3, 4
What you would do is add the two numbers in the middle, and divide by two.
In this case, 2 and three are in the middle, so you would add 2 and 3, which is 5. Then you would divide 5 by two which is 2.5
2.5 Would be your median.
Hopefully this made sense, please ask questions if you have any.
1. So far, Marta has correctly predicted the winner of 6 out of 13 football games. She wants to know how many consecutive games she would have to predict correctly to raise the percent of correct predictions to 65%. (a) Write an equation to represent this situation. (3 points) (b) Solve the equation. Show all steps. (5 points) (c) Answer the question. How many consecutive games must she predict correctly to raise her percent to 65%? (1 point)
Answer:
[(6 + x) / 13+x] = 0.65
7
Step-by-step explanation:
Given that:
Total number of games = 13
Number of correct prediction = 6
Number of correct predictions needed to raise prediction % to 65%
(Number of correct predictions) / (total number of games) = 0.65
Let x = number of additional consecutive correct predictions
[(6 + x) / 13+x] = 0.65
Where x = number of consecutive predictions required
6 + x = (13 + x) * 0.65
6 + x = 8.45 + 0.65x
x - 0.65x = 8.45 - 6
0.35x = 2.45
x = 2.45 / 0.35
x = 7
7 consecutive correct predictions

Emma is 10 years old. she asked her father how old he is. her father answered, "when you are my age I will be 70." how old is Emma's father.
Answer:
40
Step-by-step explanation:
Emma age: yE = 10 + x (x is timeline)
Father age: yF = A + x (x is timeline, A is Father age today)
in time x1: Emma will be A years old, and Father will be 70 years old.
yE (x1) = 10 + x1 = A
yF (x1) = A + x1 = 70
System of equations with unknown values: x1 and A.
substract equation 1 - equation 2:
10 - A = A - 70 ⇒ 80 = 2A ⇒ A = 40
So, father is 40 years old now
Emma's father is 40 years old
Let the age of Emma father be y
Age of emma = 10 years
In x years time;
Emma age will be 10 + xFathers age will be y + xIf in x1 years time, Emma will be y years old and his father will be 70 years old
Emma age: yE = 10 + x (x is timeline)
Emma's current age will be 10 + x = yHis father;s current age will be y + x = 70
Solving both equations simultaneously;
10 - y = y - 70
10+70 = y + y
80 = 2y
2y = 80
y = 80/2
y = 40 years
Hence Emma's father is 40 years old

If Gabe's Soccer Ball Company is able, due to competitive pressure, to charge $60 for a new soccer ball, while one soccer ball costs $28 to make, plus $15,000 per month in overhead costs (mostly Gabe's extravagant salary) find: a. The average cost c(x) of producing each soccer ball b. Algebraically find the number of soccer balls Gabe's company must produce per month in order to break even (Profit = 0). Profit = Total Revenue – Total Cost c. Algebraically find the number of soccer balls Gabe's company must make to earn a profit of $10,000 per month. d. If Gabe took a pay cut to reduce the overhead costs to $8,000 per month, how many fewer balls would the company have to sell to break even. (There are multiple ways to get this result).
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Selling price= $60
Unitary variable cost= $28
Fixed costs= $15,000
First, we need to calculate the average total cost:
Average cost= total cost / number of units
For example, for 1 unit and 10,000 units:
1 unit:
Average cost= 15,028/1 = 15,028
10,000 units:
Average cost= (15,000 + 28*10,000) / 10,000
Average cost= $29.5
Now, we can calculate the break-even point in units:
0= (60*x) - (28*x) - 15,000
x= number of units to break-even
0= 32x - 15,000
15,000/32= x
468.75=x
break-even point in units= 469
For the desired profit of $10,000:
10,000 = (60*x) - (28*x) - 15,000
25,000= 32x
781.25= x
Break-even point= 782 units
Finally, fixed costs dropped by $8,000:
0= 32x - 7,000
x= 7,000/32
x= 218.75
Break-even point= 219
Difference= 250 units

A jeweler has 36 inches of sliver chain. She needs 5 times that much to make some necklaces. How much sliver chain does the jeweler need to make her necklaces?
Answer:
180 inches
Step-by-step explanation:
36x5= 180
Answer:
if she already has 36 inches and we are tying to find how much she need we need to take that 5 and multiple it to the 36 because the word TIMES means to multiple so 36x5= 180. so your answer will be she will need 180 in (since that is the measurement we are using)

Answer:
C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a = 3.
Step-by-step explanation:
Given the points (5, 15) and (-5, -15) are plotted using the equation y = a•x, this shows a proportional relationship between y and x.
Thus using any of the points, say (5, 15), x = 5, and y = 15, thus:
a = y/x = 15/5
a = 3
Therefore, the value of a, which is 3, is the number that the x-values, 5 and -5, are multiplied by to get the corresponding y-values, 15 and -15.
As we can see, if we multiply each of the x-values by 3, it will give us their corresponding y-values.
