Answer:
x=90
Step-by-step explanation:
Let's solve your equation step-by-step.
x/9−5=5
Step 1: Simplify both sides of the equation.
x/9−5=5
1/9x+−5=5
1/9x−5=5
Step 2: Add 5 to both sides.
1/9x−5+5=5+5
1/9x=10
Step 3: Multiply both sides by 9.
9*(1/9x)=(9)*(10)
x=90
Answer:
x=90
Answer:
x = 90
Step-by-step explanation:
x /9 − 5 = 5
1 /9 x + −5 = 5
Then add 5 to both sides
1 /9 x − 5 + 5 = 5 + 5
1 /9 x = 10
Then you multiply both sides by 9.
9*( 1 /9 x)=(9)*(10)
Answer:
x=90

I am thinking of 3 positive whole numbers. the mode is 5,the median is 5, and the range is 9. work out the three numbers.
Answer:
The 3 positive whole numbers would be:
5, 5 , 14
Step-by-step explanation:
We need to find 3 positive whole numbers
The mode is 5
The median is 5
The range is 5
If the mode is 5 it means 5 is most repeated number, as mode is most repeated number of series.
So, it means we have two 5
We know that range can be found by: [tex]Range=Maximun\:Value-Minimum\:Value[/tex]
If we consider minimum value to be 5
[tex]9=Maximun\:Value-5\\Maximun\:Value=9+5\\Maximun\:Value=14[/tex]
So, the 3 positive whole numbers would be:
5, 5 , 14
having mode 5, median 5 and range 9

PRECISION Should you use an open circle or a closed circle in the graph of
the inequality b 2 -42? Explain.
Answer:
When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to". To CHECK an inequaltiy, it is not possible to test every value.
Step-by-step explanation:
In a sale, normal prices are reduced by 17%.
The normal price of a washing machine is reduced by £42.50
Work out the sale price of the washing machine.
Answer:
The sale price of the washing machine is £207.50.
Step-by-step explanation:
Percentages
To find a percentage of a given number, the procedure is multiplying the percentage by the number and divide by 100.
Suppose the normal price of the washing machine was x before the discount. The discount is:
17% of x = 17/100 * x = 0.17x
This discount is given as £42.50, thus:
0.17x = £42.50
Solving:
x = £42.50/0.17
x = £250
The sale price is:
£250 - £42.50 = £207.50
The sale price of the washing machine is £207.50.
Please use the following data to build a regression model and write a summary. IV is sugar and DV is calories.
Sugar: 5, 8, 9, 10, 15, 18, 14, 17, 20, 22, 24, 26, 30 ,30, 32
Calories: 20, 30, 60, 70, 100, 95, 70, 83, 103, 112, 130, 80, 95, 130, 112
Answer:
y = 3.0453 + 29.1542x
Step-by-step explanation:
Given the data:
Sugar (X) : 5, 8, 9, 10, 15, 18, 14, 17, 20, 22, 24, 26, 30 ,30, 32
Calories (Y) : 20, 30, 60, 70, 100, 95, 70, 83, 103, 112, 130, 80, 95, 130, 112
To obtain the regression model :
General form of a regression equation :
y = c + mx
y and x are the dependent and independent variables ;
m = slope ;
Thus ;
Regression model for the data above is:
y = 3.0453 + 29.1542x

triangle sum and exterior angle theorem.
find the x
please help i’m really bad at this and don’t understand!!
Did two of them for you as reference for the rest.
Explanation for #1
The sum of all the angles in a triangle is 180. Simply add the given angles. Take 180 and subtract the sum of the given angles
180 - (58 + 47) = 75
Missing angle is 75
Explanation for #4
A straight angle is 180 degrees. Same thing as the first: add the given angles then take 180 and subtract it.
Then take 180 again and subtract the answer you got from the first step.
180 - (21 + 34) = 125
180 - 125 = 55
The missing angle is 55
The value of x in triangle 1 is 75 degrees
The value of x in triangle 2 is 63 degrees
The value of x in triangle 3 is 20 degrees
The value of x in triangle 4 is 55 degrees
The value of x in triangle 5 is 23 degrees
The value of x in triangle 6 is 17 degrees
The value of x in triangle 7 is 85 degrees
The value of x in triangle 8 is 30 degrees
The value of x in triangle 9 is 147 degrees
The value of x in triangle 10 is 29 degrees
The value of x in triangle 11 is 60 degrees
The value of x in triangle 12 is 27 degrees
Description of a triangleA triangle is a polygon with three sides. The sum of angles in a triangle is 180 degrees. The sum of two opposite interior angles is equal to the external angle.
Types of triangles
Equilateral triangle Right-angles triangle Isosceles triangleScalene tringleDetermining the value of xTriangle 1: 180 - (58 + 47) = 75 degree
Triangle 2: 180 - 96 - 21 = 63 degrees
Triangle 3: 180 = (3x - 1 + 31 + 90)
180 = 120 + 3x
180 - 120 = 3x
60 = 3x
x = 20 degrees
Triangle 4: 21 + 34 = 55 degrees
Triangle 5: 100 = 2x + 3 + 51
100 = 2x + 54
100 - 54 = 2x
46 = 2x
x = 23 degrees
Triangle 6: 94 = 60 + 2x
94 - 60 = 2x
34 = 2x
x = 17 degrees
Triangle 7: 180 - 52 - 43 = 85 degrees
Triangle 8: x + 2x + 3x = 180
6x = 180
x = 30 degrees
Triangle 9: 2x - 2 + x + 5 = 90
3x + 3 = 90
3x = 90 - 3
3x = 87
x = 29 degrees
Triangle 10: 180 - 10 - 23 = 147 degrees
Triangle 11: 180 = x + x + x
180 = 3x
x = 60 degrees
Triangle 12: 180 = 3x - 17 + x + 40 + 2x - 5
180 = 6x + 18
180 - 18 = 6x
162 = 6x
x = 27 degrees

A scientist wants a 64 milliliter acid solution with a concentration of 8%. She has concentrations of 2% and 10%. How much
of each solution must she use to get the desired concentration?
Answer:
16 milliliters of 2% solution
48 milliliters of 10% solution
Step-by-step explanation:
x = 2% solution
y = 10% solution
System of Equations:
x + y = 64
.02x + .10y = 64(.08)
use Substitution: y = 64 - x
.02x + .10(64 - x) = 5.12
.02x + 6.4 - .10x = 5.12
-.08x = -1.28
x = 16
y = 64 - 16 which equals 48

the theaters sell tickets for a concert. tickets for the lower level are $35 each and tickets for the upper level are $25 each. the theater sold 350 tickets for $10,250. how many tickets were sold in each section
9514 1404 393
Answer:
150 lower level200 upper levelStep-by-step explanation:
Let x represent the number of lower-level tickets sold. Then the total revenue is ...
35x +25(350-x) = 10250
10x +8750 = 10250 . . . simplify
10x = 1500 . . . . . . . . . subtract 8750
x = 150 . . . . . . . . . . . lower-level tickets sold
350-x = 200 . . . . . upper level tickets sold
There were 150 tickets sold for the lower level, and 200 sold for the upper level.

Acomputer store buys a computer system at a cost of $468.60. The selling price was first at $781,
but then the store advertised a 30% markdown on the system. Answer parts a and b.
If a computer store buys a computer system at a cost of $468.60. The selling price was first at $781, but then the store advertised a 30% markdown on the system. The current sale price is $546.7.
What is the current sales price?Given data :
Cost price = $468.60
Selling price = $781
Markdown = 30% or .30
Hence,
Let x represent the current sales price
781 - (30% × 781) = x
781 - 781 × 0.3 = x
781 × (1 - 0.3) = x
781 × 0.7 = $546.7
Therefore $546.7 is the current sale price for the computer system.
