| 4x-13 | = 5x+4
Solve
Answer:
x = 1
Step-by-step explanation:
The absolute value always gives a positive value. However, the expression inside can be positive or negative , so
4x - 13 = 5x + 4 ( subtract 4x from both sides )
- 13 = x + 4 ( subtract 4 from both sides )
- 17 = x
OR
- (4x - 13) = 5x + 4 , simplify left side
- 4x + 13 = 5x + 4 ( subtract 5x from both sides )
- 9x + 13 = 4 ( subtract 13 from both sides )
- 9x = - 9 ( divide both sides by - 9 )
x = 1
As a check
Substitute these values into the equation and if both sides are equal then they are solutions.
x = - 17
left side = | 4(- 17) - 13 | = | - 68 - 13 | = | - 81 | = 81
right side = 5(- 17) + 4 = - 85 + 4 = - 81 ≠ 81
Then x = - 17 is an extraneous solution
x = 1
left side = | 4(1) - 13 | = | 4 - 13 | = | - 9 | = 9
right side = 5(1) + 4 = 5 + 4 = 9
Then solution is x = 1

3. How many faces do each of the following have?
cube - 6 facessquare pyramid - 5 facestriangular pyramid - 4 facespentagonal pyramid - 6 facesHope this helps!
A cube has six sides that are numbered 1 to 6. The sides numbered 1, 3, and 5 are yellow, and the sides numbered 2, 4,
and 6 are orange. What is the probability of rolling the cube and getting a yellow and even number?
Explanation:
The yellow sides are 1,3,5 which are odd numbers. So it's impossible to get an even number that's a yellow side. That's why 0 is the answer here. A probability of zero represents cases when the event can never happen.
The ratio of men to women working for a company is 6 to 5 . If there are 65 women working for the company, what is the total number of employees?
Step-by-step explanation:
[tex]\frac{men}{women} =\frac{6}{5}[/tex]
If there are 5 women = 6 men
If there are 5(13) women = 6(13) men
If there are 65 women = 78 men
So there are 65 + 78 = 143 employees.

A linear function has a slope of 8/3 and passes through the point (0,5). What is the equation of the line?
This problem already gave us the slope and y-intercept, so all that's left to do is plug those two values into slope-intercept form.
Slope-Intercept Form: y = mx + b
---m is the slope
---b is the y-intercept
y = 8/3x + 5

If you plotted the points in the table and connected
them in order with a smooth curve, what shape
would it be?
a line
a U shape
a semicircle
Answer:
U shaped.
Step-by-step explanation:
When x = 0 , f(x) = 6
when x =1 yf(x) = 0
when x = 2 f(x) = -2
x = 3 f(x) = 0
x = 4 f(x) = 6.
So the graphs falls from the left and rises to the right in the form of a U.
You can draw a rough graph to confirm this.
Answer:
u Shaped

One grain of this sand approximately weighs 7 x 10^-5 g. How many grains of sand are there in 6300 kg of sand ? Give your answer in standard form
Answer:
90 000 000 000 Grains
Step-by-step explanation:
one grain equal approximately 0.00007 grams.
convert 6300 kg into grams (multiply by 1000) and that equals 6 300 000g.
divide that by the weight of a single grain and you get the number of grains in that weight. So 6300000/0.00007=90 000 000 000 grains.
The number of grains of sand are there in 6300 kg of sand is 90,000,000.
What is scientific notation?Scientific notation is a method for expressing a given quantity as a number having significant digits necessary for a specified degree of accuracy, multiplied by 10 to the appropriate power such as [tex]1.56\times10^7[/tex].
Given that, one grain of this sand approximately weighs [tex]7\times10^{-5}[/tex] g.
6300 kg of sand
Number of grains = [tex]\frac{6300}{7\times10^{-5}}[/tex]
= [tex]900\times10^5[/tex]
= 90,000,000
Therefore, the number of grains of sand are there in 6300 kg of sand is 90,000,000.

The height of a triangle is 4 cm more than twice its base. The area of the triangle is 168 cm^2. What is the length of the base of the triangle?
a) 12 cm
b) 6 cm
c) 7 cm
d) 14 cm
Answer:
12cm
Step-by-step explanation:
h = 2b + 4
Area = 168 cm²
b = ?
Area = b*h / 2
168 = b (2b + 4) / 2
168 = 2b² + 4b/ 2
168 = b² + 2b
b² + 2b - 168 = 0
(b + 14) (b - 12) = 0
b = -14
b = 12
The base of a triangle cannot be -ve. So b = 12cm

Answer: [tex]4\sqrt{5}[/tex]/9.0
Step-by-step explanation:
Simple way: Pythagorean Theorem
[tex]a^{2} +b^{2} =c^{2}[/tex]
C being hypotenuse. A and B are bases that are interchangeable.
In this question, you are missing the hypotenuse.
a= 8, b=4 c=?
[tex]8^{2}+4^{2}=c^{2}[/tex]
[tex]64+16=c^{2}[/tex]
To get rid of [tex]c^{2}[/tex]. Square both sides.
[tex]\sqrt{64+16} =\sqrt{c^{2} }[/tex]
[tex]\sqrt{80}=c[/tex]
Simplify [tex]\sqrt{80}[/tex]
[tex]\sqrt{4*4*5} =4\sqrt{5}[/tex]

A store had 2 BLUE chairs for $22.78 or 6 RED chairs for $67.80.
Type in the rate for each color of chairs below. blue $_______ Red $_______
Which color chair has a lower unit price? ________
Answer:
Blue chairs
Step-by-step explanation:
To get the unit rate of red chairs, you simply divide 22.78/2, which equals $11.39
So the unit rate of RED chairs is $11.39
To get the unit rate of the blue chairs, you simply divide 67.80/6 which equals $11.30
So the unit rate of BLUE chairs is $11.30
Unit rate is simply the cost of one item (in this case chairs) the unit rate stays the same. If we flipped the operation on blue chairs and did 11.30*6, it equals $67.80. The same goes for the red chairs, if we did 11.39*2 it equals $22.78.
