Step-by-step explanation:
8 can be written as 2³
so 8^-1 can be written as 2^-3
Solve for like terms
=> (2^-3)/(2^-4) = 2
=> 2×5³= 2×125 = 250
250 is your answer.
Hope this helps you.
A person who weighs 200 pounds on Earth would weigh about 32 pounds on the moon. Find the weight of a person on Earth who would weigh 15 pounds of the moon
Answer:
93.75 pounds
Step-by-step explanation:
Set up a proportion where x is the weight of a person on Earth:
[tex]\frac{200}{32}[/tex] = [tex]\frac{x}{15}[/tex]
Cross multiply and solve for x
32x = 3000
x = 93.75
So, the person would weigh 93.75 pounds on Earth
On Earth, a person weighing 93.75 pounds would weigh around 15 pounds on the moon.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
If a person who weighs 200 pounds on Earth would weigh about 32 pounds on the moon, we can set up the following proportion to find the weight of a person on Earth who would weigh 15 pounds on the moon:
200 pounds : 32 pounds = x pounds : 15 pounds
200 pounds / 32 pounds = x pounds / 15 pounds
⇒ 200/32 = x/15
Apply the Cross-multiplication operation, we get:
⇒ 200 × 15 = 32 × x
Solving for x, we get:
⇒ x = (200 × 15) / 32
⇒ x = 3000/32
Apply the division operation
⇒ x = 93.75 pounds
Therefore, a person who weighs 93.75 pounds on Earth would weigh about 15 pounds on the moon.

Unitary method question.
Answer:
the better value is £9
Step-by-step explanation:
unitary method..
find out how much 1kg will cost in the supermarket and multiply by 12.5kg
For the supermarket
1.83/2.5= 0.732 for one kg.
for 12.5 kg
0.732× 12.5= £9.15
hence the farm shop price is lower than the supermarket price

15-2.5x=40 which is the correct first step to solve the liner equation
Answer:
subtract 15 from both sides if you're solving for x
The first step should be subtracting 15 from both side.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. Every mathematical equation has the formula L.H.S = R.H.S.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given equation:
15-2.5x=40
Now, to solve for x the first step should be subtracting 15 from both side
15 - 2.5x - 15 = 40- 15
-2.5x = 25
Now, divide by (-2.5) from both side
-2.5x / (-2.5)= 25/(-2.5)
x= -10
Hence, the first step should be subtracting 15 from both side.

Write the equation of a line going through the points (4,2) and (7,-3).
Answer:
Equation of the straight line passing through the point ( 4,2) and (7,-3) is
5 x + 4y - 28=0
Step-by-step explanation:
Step(i):-
Given points are ( 4,2 0 and ( 7,-3)
Slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{-3-2}{7-4} = \frac{-5}{4}[/tex]
Step(ii):-
Equation of the straight line passing through the point ( 4,2) and
having slope m = [tex]\frac{-5}{4}[/tex]
y - y₁ = m( x- x₁ )
[tex]y - 2 = \frac{-5}{4} ( x-4)[/tex]
4( y -2) = -5( x-4)
4 y - 8 = - 5x +20
5x +4y -8 -20=0
5 x + 4y - 28=0
Final answer:-
Equation of the straight line passing through the point ( 4,2) and (7,-3) is
5 x + 4y - 28=0
solve for X
5(x+8)= 8(x+1)
Answer:
x = [tex]\frac{32}{3}[/tex] (see below)
Step-by-step explanation:
First, use distributive property:
5 (x + 8) = 8 (x + 1)
5x + 40 = 8x + 8
Then, simplify the equation by combining like terms. You want to isolate the variable to one side of the equation so you can solve for it. Here what I'm talking about:
5x + 40 = 8x + 8
-5x -5x
-------------------------
40 = 3x + 8
-8 -8
-----------------
32 = 3x
Now, divide both sides by 3 to get the value of x:
3x = 32
x = [tex]\frac{32}{3}[/tex]
or
x ≈ 10.7
Answer:
x= 32/3
Step-by-step explanation:
5(x+8)= 8(x+1)
5x+40=8(x+1)
5x=40=8x+8
5x+40=8x+8
5x+40-40=8x+8-40
5x=8x-32
5x=8x-32
5x-8x=8x-32-8x
-3x=-32
-3x = -32
(Divide both by -3)
x=32/3

what is an equation of the line that passes through the point (5,1) and is parallel to the line x+y=9
3х - 2y = 11
Need the answer
Answer:
Step-by-step explanation:
Im assuming you the equation in terms of y, that's the conventional thing in high school math.
Add 2y to both sides:
3x = 2y + 11
Subtract 11 from both sides:
2y = 3x - 11
Divide both sides by 2:
y = (3x - 11)/2

Answer:
[tex]\dfrac{5}{3}\ \text{pounds}[/tex]
Step-by-step explanation:
George bought a bag of dog food that was 1/3 pounds.
George fed his dog 5 times with this bag of food.
We need to find how many pounds of food did the dog eat at each feeding. Let it be x.

What is the vertex of this quadratic function.
(x-4)2 + 3 = 0
Answer:
(4, 3)
Step-by-step explanation:
Please use " ^ " to indicate exponentiation: (x-4)^2 + 3 = f(x) (which is not 0)
Comparing:
f(x) = (x - 4)^2 + 3 to the general vertex equation
f(x) = (x - h)^2 + k
tells us that the vertex is (h, k): (4, 3)
If the selling price of a radio is Rs 365 and lose is the Rs 79 find the purchased price
Answer:
Purchase price of radio is Rs 444.
Step-by-step explanation:
It is given that:
Selling price of radio = Rs 365
Amount of loss = Rs 79
Let,
x be the purchase price.
Loss = Purchase price - Selling price
79 = x - 365
x = 365 + 79
x = Rs. 444
Thus,
Purchase price of radio is Rs 444.
