a) Write this information in the form of an equation.
b) Solve the equation to find the number I was thinking of.

Answers

Answer 1

Answer:

a) (X - 4)x 5 = 15

b) the answer is 7

Step-by-step explanation:

divide 15 by 5 and then add 4, do the equasion backwards :)

Answer 2

The solution of the given equation (X - 4)x 5 = 15 would be equal to 7.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Now we will try solving it first using the method of substitution in which we express one variable in other variable's form and then you can substitute this value in other equation to get linear equation in one variable.

We are given that a number subtract 4, then divide by 5. The result equals 15.

a) The equation form as

(X - 4)x 5 = 15

b) Now solving the equation as;

(X - 4)x 5 = 15

5x - 20 = 15

x = 35/7

x = 7

Hence, the answer is 7

Solve for x.

(x + 5)(x + 4) = 9x + 141

Answers

Answer: x=11 or x=-11

Step-by-step explanation:

Answer:x=11 or x=-11

Step-by-step explanation:  First, Use the FOIL method.

(x+5)(x+4)=9x+141

First: [tex]x^{2}[/tex]

Outer: 4x

Inner:  5x

Last:  5x4=20

Combine Like terms and write in standard form: [tex]x^{2}[/tex]+9x+20

Set up new equation:[tex]x^{2}[/tex]+9x+20=9x+141

Subtract 9x from both sides: [tex]x^{2}[/tex]+20=141

Subtact 20 from both sides: [tex]x^{2}[/tex]=121

Sqr root 121: [tex]\sqrt{121}[/tex] =11

Remeber a sqr root of a positive number can be positive and negative so x= 11 or -11

The range of f(x) = |x| is y ≥ 0. If a < 0 and b ≠ 0 for g(x) = a|x| + b, what is the range of function g?

Answers

The required range of the function g(x) = a|x| + b is y ≥ 0.

Let's analyze the function g(x) = a|x| + b step by step to determine its range.

The function |x| represents the absolute value of x, which means it always yields non-negative values. Therefore, a|x| will also be non-negative for any value of x.

Adding b to a non-negative value will shift the entire range up by b units, but it will still be non-negative.

Since a < 0, a|x| will be negative when x is positive. However, the absolute value function ensures that it will be positive when x is negative, balancing out the effect.

Finally, adding the constant term b to a|x| makes the entire range of g(x) non-negative.

In summary, the range of g(x) = a|x| + b is y ≥ 0.

The following are the ages (years) of 5 people in a room:
17, 21, 15, 15, 25
A person enters the room.
The mean age of the 6 people is now 25.
What is the age of the person who entered the room?

Answers

Answer:

57 years

Step-by-step explanation:

The mean of a set of numbers is given as the ratio of the sum of the numbers to the number of numbers in the given data set.

Hence given that the age of 5 people are 17, 21, 15, 15, 25 and a 6th person joins the set, making the mean age 25, let the age of the new person that joined be x then

25 = (x + 17 + 21 + 15 + 15 + 25)/6

25 = (x + 93)/6

Multiply both sides by 6

150 = x + 93

subtract 93 from both sides

x = 150 - 93

x = 57 years

The age of the person who entered the room is 57 years

(7x+3)
(8x+1)°

Answers

Answer:

        x = 2

Step-by-step explanation:

Angles (7x + 3)° and (8x + 1)° are corresponding angles

Therefore:

m║n      ⇒      (7x + 3)° = (8x + 1)°

(7x)° + 3° = (8x)° + 1°     {subtract (7x)° from both sides}

3° = x° + 1°                   {subtract 1° from both sides}

2° = x°                          

x = 2

You are conducting an experiment to test the density of a new recipe for chocolate cake. You will test the recipe with 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).


How many treatments are there?

Answers

Answer: There are 9 possible treatments .

Step-by-step explanation:

There are 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).

By Fundamental counting principle,

Number of treatments  = (Number of different baking temperatures) x (Number of different baking  times)

= 3 x 3 = 9

Hence, there are 9 possible treatments .

The number of treatments is 9.

Given that,

You will test the recipe with 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).

Based on the above information, the calculation is as follows:

Here we used the fundamental counting principle.  

[tex]= 3 \times 3 \\\\= 9[/tex]

Therefore we can conclude that the number of treatments is 9.

Drag numbers to write an equation for the line in slope-intercept form. Numbers may be used once, more than once, or not at all.

Graph of a diagonal line with x-axis and y-axis. A line is passing through co-ordinates (0,5) and (2,-3).

Answers

Answer:

y = -4x + 5

Step-by-step explanation:

Here, we want to get the equation of the line that passes through the given points

The general form is;

y = mx + b

where m is the slope and b is the y intercept

To find the slope, we use the slope formula

this is ;

m = (y2-y1)/(x2-x1)

(x1,y1) = (0,5)

(x2,y2) = (2,-3)

m = (-3-5)/(2-0) = -8/2 = -4

To get the y-intercept we simply substitute one of the points

But we know that the y-intercept is the y-value when x = 0

From the point we can see (0,5) which means that the y-intercept is 5

so the equation of the line is;

y = -4x + 5

The equation of the graph in slope intercept form is y = -4x + 5

Using slope intercept equation

y = mx + b

where

m = slope

b = y- intercept

Therefore,

Let's take 2 coordinates to get the slope.

(1, 1)(0, 5)

y-intercept  = 5

Therefore,

m = 5 - 1 / 0 - 1 = - 4

y = -4x + 5

c.6 i think, sorry if it’s wrong but my reasoning was that 50 + 58 = 108 and the interior of a triangle is 180 degrees so then you would subtract 180 - 108 = 72, then i did some guess work plugging in the different answers into the equation and 11 x 6 + 6 = 72 which was the missing angle from before

Answer:

it's a parallelogram so the 50° is an alternate angle to the one you are trying to work out.

11x = 50-6

11x = 44

Therefore, a triangle is possible with the given measurements,

Let us assume there is another triangle with same measurement with same measurements 7 cm, 6 cm, and 9 cm.,

By SSS congruency criteria both the triangles will be congruent.

Answers

Answer:

Step-by-step explanation:

the journey will last

100 miles/25 mph=4 hours

Lorry travels 100 miles at a speed of 25 mph for 4 hours.

What is average speed?

Average speed is calculated by dividing the entire distance that something has traveled by the overall amount of your time it took it to travel that distance. Speed is how briskly something goes at a specific moment. Average speed measures the typical rate of speed over the extent of a visit.

How to calculate time?

We know that speed=distance/time

We have been provided that speed=25 miles per hour and distance is 100 miles. so so as to calculate the time we've got to merely put the values of speed and distance within the formula:

Time=distance/speed

=100/25

=4

Hence lorry will take 4 hours to hide 100 miles at a speed of 25 miles per hour.
