sarah lost her science book her school charges a lost book fee equal to 75% of the cost of the book sarah recieved a notice she owes the school $60 for the book how much did the school pay for the book
Answer: $80
Step-by-step explanation:
You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.
Therefore
$60 = 75%
Now we have to find out what amount of money would be equivalent to 100%:
To do this, find out what amount of money would be equivalent to 25% first.
You can do this by dividing both values by 3.
60 / 3 = 20
75 / 3 = 25
So now $20 = 25%
Now find 100% (which is the original amount) multiply each value by 4 :
$80 = 100%
So the school payed $80 for the book.
hope this helps :)

Does (3, 10) make the inequality y > 2x + 2 true?
Answer:
Yes, it makes it true
Step-by-step explanation:
Plug in 3 and 10 as x and y into the inequality:
y > 2x + 2
10 > 2(3) + 2
10 > 6 + 2
10 > 8
Since 10 is bigger than 8, this inequality is true.
So, (3, 10) makes the inequality true.

Select the correct answer. Which number has a repeating decimal form? A. 15 B. 11/25 C. 3/20 D. 2/6
Answer:
its D 2/6
Step-by-step explanation:
From the given options 2/6 has a repeating decimal form. Therefore, option D is the correct answer.
From the given options we need to find which number has a repeating decimal form.
What is a repeating decimal form?A repeating decimal or recurring decimal is the decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero.
Now, from option A:
1/5=0.2
From option B:
11/25=0.44
From option C:
3/20=0.15
From option D:
2/6=0.3333333

13x = 2(5x+3) solve for x
Answer:
13x=2(5x+3)
13x=10x+6
13x-10x=6
3x=6
x= 6/3
x=2
Answer:
x=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
13x=2(5x+3)
13x=(2)(5x)+(2)(3)(Distribute)
13x=10x+6
Step 2: Subtract 10x from both sides.
13x−10x=10x+6−10x
3x=6
Step 3: Divide both sides by 3.
3x/3=6/3

Cdef maps to jklm with the transformation (x,y) to (4x,4y) to (x-4,y-9). What is the value of ef/lm.
Answer:
EF / LM = 1 / 4
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.
Dilation is the enlargement or reduction in the size of a figure. If a point A(x, y) is dilated by a scale factor of k, the new point is at A'(kx, ky).
Translation is the movement of a point right, left, up or down. If a point A(x, y) is translated a units left and b units down, the new point is at A'(x - a, y - b).
Translation preserves the size and shape of an object. Dilation preserves the shape but not the size.
Cdef maps to jklm with the transformation (x,y) to (4x,4y) to (x-4,y-9).
CDEF was first dilated by a scale factor of 4 to get (4x,4y) before it was translated by (x-4,y-9). Since dilation changes the size of the figure, hence JKLM would be 4 times the size of CDEF. Therefore:
LM / EF = 4
EF / LM = 1 / 4

Tom used 3/8 of a piece of ribbon for a kite tail. From the remaining 5/8 of the ribbon, he cut pieces to tie weights on the kite tail. Each tie was 1/12 of the whole ribbon. How many times did he cut?
Answer:
7.5
Step-by-step explanation:
Fraction used for kite = 3/8
Fraction of entire ribbon = 1/1
Fraction left after making kite :
Fraction left = 1 - 3/8 = (8 - 3) / 8 = 5/8
Fraction used as tie = 1/12
Number of ties obtainable from the fraction left :
Fraction of ribbon left ÷ fraction used as tie
5/ 8 ÷ 1/ 12
5/8 * 12 / 1
= 60 / 8
= 7.5

The difference btwn 2 villages is over 24km Write this as an algebraic statement
To solve :
Let us represent the two villages with an alphabet :
Let:
Village 1 = x
Village 2 = y
The difference between the two villages : |Village 1 - Village |, that is x - y
The difference is more than 24 km, that is > 24
Hence,
Algebraically,

find the first term and the common difference of an arithmetic progression in which t5=3x-y and t11=5y
t5 refers to term 5 and t11 refers to term 11
first term: 5x-5y
common difference: -x/2 + y
The common difference is d = -0.5x + y and the first term is 5x-5y
Geometric progressionThe nth term of the geometric progression is expressed as:
[tex]T_n=a+(n-1)d[/tex]
where;
a is the first termr is the common ration is the number of termsThe fifth term of the sequence is expressed as:
[tex]T_5=a+4d=3x-y[/tex]
[tex]T_{11}=a+10d=3x-y[/tex]
Take the difference of the terms:
[tex]4d-10d=3x-y-5y\\-6d=3x-6y\\d= -0.5x+y[/tex]
Get the first term:
a = 3x - y - 4(-0.5x+y)
a = 3x - y + 2x - 4y
a = 5x - 5y
Hence the common difference is d = -0.5x + y and the first term is 5x-5y

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).
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

Answer:
x = 8, y = 8
Step-by-step explanation:
So we know angle CAB is congruent to angle ACB so both angles are 69.
Now we add 69+69 and we get 138. Subtract from 180.
180 - 138 = 42.
Now, we set up the equation to 5x+2=42,
subtract two from both sides and get 5x = 40,
divide both sides by 5 and you get x=8.
You can simply plug in x to 5 and add two and still get 42.
