During a 40% off sale, Tessa pays $24 for a sled. What was the original price?
Answer:
$33.6
Step-by-step explanation:
24*1.4=33.6
the 1.4 represents the added 40% to find the original price of the sled
Answer:
original price = 40
Step-by-step explanation:
make an equation using the information given in the question, x will represent the original price
x - 0.4x = 24
or
x - 2/5x = 24
solve for x
x - 2/5x = 24
3/5x = 24
x = 40

If you solve the equation for ax+by/c=d for x, what would you get?
Answer:
x=d/a - by/ac
Steps:
ax+by/c=d
(cax+by)/c=d
cax+by=cd
cax=cd-by
x=(cd-by)/ca
x=cd/ca - by/ca
x=d/a - by/ac

what is the solution of the system equation?
y=3x+7
y=x-9
Answer:
y=-17, x=-8
Step-by-step explanation:
x-9=3x+7
Isolate x for x-9=3x+7;
x-9=3x+7
Add 9 to both sides:
x-9+9=3x+7+9
Simplify;
x=3x+16
Subtract 3x from both sides;
x-3x=3x+16-3x
Simplify;
-2x=16
Divide both sides by -2;
-2x/-2=16/-2
simplify: -2x/-2
=x
Simplify 16/-2:
x=-8
For y=x-9 substitute x=-8;
y=-8-9
Simplify;
y=-17
The solutions to the System of equations are;
y=-17, x=-8

Use three different values of n to demonstrate that 2n + 3n is equivalent to 5n.
Answer: n=1,2,3
Step-by-step explanation: if we plug in these numbers 2*1+3*1=5*1 this works. If we do this for 2 then we have 2*2+3*2=10 and 5*2= 10 this also works. The same thing with 3. 2*3+3*3=15 5*3=15

What is the simplified form of √45
Answer:
3√5
Step-by-step explanation:
The largest perfect square of the factors of 45 is 9. We can therefore convert √45 like this:
√9 × 5
Next, we separate the numbers inside the √ as such:
√9 × √5
√9 is a perfect square that equals 3. We can therefore put 3 outside the radical and get the final answer to square root of 45 in simplest radical form as follows:
3√5

Each side of a square piece of sheet metal is 6 meters long. What is the sheet metal's area?
Answer:
36 meters^2
Step-by-step explanation:
Part A: Let y represent the number of rabbits after x years. Which functioncan be used to model y as a function of x, where x is a non negative number ?
А. y = 10 (3) ^ (x - 1)
В. y = 10 (3) ^ x
C. y = 3 (10) ^ (x - 1)
D . y = 3 (10) ^ x
Answer:
y = 10(3)x
Step-by-step explanation:
The exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.
What do you mean by domain and range of a function?For any function y = f(x), Domain is the set of all possible values of [x] for which [y] exists. Range is the set of all values of [y] that exists for the given domain.
Given is rate of increase of a rabbit's population.
The exponential function that can represent the population of rabbits after [x] years can be written as -
y = 10(3)ˣ
Refer to the graph attached.
Hence, the exponential function that can represent the population of rabbits after [x] years is y = 10(3)ˣ.

If the sum of the measures of the interior angles of a polygon is 1920°, how many sides does it have? math
Answer: There is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Step-by-step explanation:
The sum of the measures of interior angles of a polygon with [tex]n[/tex] sides is given by:-
[tex](n-2)\times180^{\circ}[/tex]
Given: The sum of the measures of the interior angles of a polygon is 1920°.
i.e. [tex](n-2)\times180^{\circ}=1920^{\circ}[/tex]
[tex]n-2=\dfrac{1920}{180}\\\\ n= \dfrac{1920}{180}+2\\\\ n=\dfrac{2280}{180}=12.67[/tex]
But number of sides cannot be in decimal.
Hence, there is no polygon with the sum of the measures of the interior angles of a polygon is 1920°.
Sarah, who is 1.72 m tall, wishes to find the height of a tree. She walks 18.77
m from the base of the tree along the shadow of the tree until her head is
in a position where the tip of her shadow exactly overlaps the end of the
tree top's shadow. She is now 5.38 m from the end of the shadows. How
tall is the tree? Round to the nearest hundredth. *
Answer:
7.7 m
Step-by-step explanation:
let's give the tree height T
T = 1.72 × (18.77+5.38)/5.38
T = 1.72 × 24.15/5.38
T = 41.538/5.38
T ≈ 7.7 m

PLZ HELP I WOULD REALLY APPRECIATE IT
Answer:
Step-by-step explanation:
i think it 8.45
Answer:
To solve this question, all we have to do is to convert - 8 5/12 to a decimal.
So we have: -8 5/12 = -8. (5/12)
This is equal to -8.41666... , where the 6 continues forever. You can express this by drawing a line above the 6, which indicates that it continues forever.

Answer:
[tex]\huge\boxed{\sf 18 cm\²}[/tex]
Step-by-step explanation:
The figure consists of 2 rectangles.
Rectangle 1 Area:
Length = 5 cm
Width = 2 cm
Area = Length * Width
A = 5 * 2
A = 10 cm²
Rectangle 2 Area:
Length = 4 cm
Width = 2 cm
Area = 2 * 4
A = 8 cm²
Area of the whole figure:
= Rectangle 1 + Rectangle 2
= 10 + 8
= 18 cm²
