Answer:
-2
Step-by-step explanation:
2/3 (x-4)=2x
or, 2x-8/3 =2x (multiply(x-4) by 2/3)
or, 2x-8 =3×2x
or, 2x-8 =6x
or, 2x-6x = 8
or, -4x = 8
or, x= 8/(-4)
or, x= -2
Expand and simplify: 2(x-4^2)+7
Suppose that the volume of water in the rain barrel
decreased by 4 5/8 gallons in four minutes. What will be
the change in the volume of water after one minute?
Answer:
Step-by-step explanation:
A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
The change in the volume of water in one minute is 1 5/32 gallons.
What is a unit rate?A unit rate is a rate for one of something.
It is written as a ratio with a denominator of one.
We have,
4 5/8 gallons decrease in 4 minutes.
This can be written as:
4 5/8 gallons = 4 minutes
37/8 gallons = 4 minutes
Dividing both sides by 4 we get,
(37/8) / 4 = 4/4 minutes
37/(8x4) = 1 minute
37/32 = 1 minute
1 5/32 gallons = 1 minute
Thus the change in the volume of water in one minute is 1 5/32 gallons.

Given the following number in standard form, how would you represent the number in the hundreds place using expanded exponential notation?
7321
Answer: 3*10^2
====================================
Work Shown:
7321 = 7000 + 300 + 20 + 1
7321 = 7*1000 + 3*100 + 2*10 + 1*1
7321 = 7*10^3 + 3*10^2 + 2*10^1 + 1*10^0
Side note: The exponents count down 3,2,1,0. You can think of a similar thing like 7x^3+3x^2+2x+1 and simply replace x with 10.
If h(x) = 5 + x and (x) = 5. which expression is equivalent to (k-1)(o)? (5+) 1 (5+) 5+ 5+ (5 + x)
(5+x)/x
K*H = 1/x(5+x) or (5+x)1/x which = (5+x)/x because (5+x)1/x = [(5+x)/1] * [1/x] and anything multiplied by one is equal to itself.
If h(x) = 5 + x and k(x) = 5 then the expression which is equivalent to (koh)(x) is 25+5x
What is a function?A relation is a function if it has only One y-value for each x-value.
The given functions are h(x) = 5 + x and k(x) = 5x
We have to find the expression which is equivalent to (koh)(x)
(koh)(x) = k(h(x))
=k(5+x)
Now we have to plug in 5+x in the function k(x)
k(5+x)=5(5+x)
=25+5x
Hence, if h(x) = 5 + x and k(x) = 5 then the expression which is equivalent to (koh)(x) is 25+5x

x = 8 and x = 7
Step-by-step explanation:
(6)
Since the triangles are similar then the ratio of corresponding sides are equal, that is
[tex]\frac{ST}{MN}[/tex] = [tex]\frac{RS}{LM}[/tex] , substitute values
[tex]\frac{x}{4}[/tex] = [tex]\frac{4}{2}[/tex] ( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
(7)
Since the prisms are similar then the ratio of corresponding sides are equal, that is
[tex]\frac{x}{35}[/tex] = [tex]\frac{2}{10}[/tex] ( cross- multiply )
10x = 70 ( divide both sides by 10 )
x = 7

The test scores you end up having in geometry class are 81 and 87. What possible scores can you earn on your next test to have a test average between 84 and 89?
Answer:
88, 89, 90, 91, 92? idrk
Answer:
A score between 84 and 99
Step-by-step explanation:
First, let's solve for what you would need to score on your next test to have an average of 84:
(81 + 87 + x)/3 = 84
(168 + x)/3 = 84
168 + x = 252
x = 84
Next, let's solve for what you would need to score on your next test to have an average of 89:
(81 + 87 + x)/3 = 89
(168 + x)/3 = 89
168 + x = 267
x = 99
That means you would have to earn a score between 84 and 99.

On her way to visit Horace Mann University, Casey stopped by Mount Rushmore in South Dakota. The park ranger gave a talk that described the history of the monument and provided some interesting facts. Casey could not believe that the carving of George Washington’s face is 60feet tall from his chin to the top of his head!
However, when a tourist asked about the length of Washington’s nose, the ranger was stumped! Casey came to her rescue by measuring, calculating and getting an answer.
How did Casey get an answer?
Answer:
using a proportion relating nose length to head height
Step-by-step explanation:
Casey measured the nose length, and found the fraction that was of the head height. Then Casey found the same fraction of 60 feet to find the actual nose length.

Casey could use a photograph, poster, postcard, or a ruler held at arm's length, to make the necessary measurements.
4x -1 = -x+9 i need help its for a testtt
Answer:
x = 2
Step-by-step explanation:
4x - 1 = -x + 9
add x to both sides.
4x + x - 1 = 9
add 1 to both sides
4x + x = 9 + 1
5x = 10
x = 2
Answer:
[tex]\boxed {x = 2}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]4x - 1 = -x + 9[/tex]
-Take [tex]x[/tex] and add it to [tex]4x[/tex]:
[tex]4x - 1 + x = -x + x + 9[/tex]
[tex]5x - 1 = 9[/tex]
-Add [tex]1[/tex] to both sides:
[tex]5x - 1 + 1 = 9 + 1[/tex]
[tex]5x = 10[/tex]
-Divide both sides by [tex]5[/tex]:
[tex]\frac{5x}{5} = \frac{10}{5}[/tex]
[tex]\boxed {x = 2}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]2[/tex].

The slope of the given data in the table will be 25.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
The formula to calculate the slope of the line will be given below:-
m = (y₂ - y₁) / (x₂ - x₁)
Given data is as below:-
Number of months Savings Principal
5 $125
6 $150
7 $175
8 $200
The slope will be calculated as below:-
m = (y₂ - y₁) / (x₂ - x₁)
m = ( 150 - 125 ) / 6 - 5 )
m = 25
Therefore, the slope of the given data in the table will be 25.
