Ryan drove 480 miles and used 20 gallons of gas. How many miles did Ryan's car get per gallon? Write an equation that would solve this problem.
Answer:
24 miles per gallon
Step-by-step explanation:
Step one:
given data
total distance covered= 480miles
The total amount of gallons used is = 20
The miles per gallon
= 480/20
=24 miles per gallon
Step two:
hence the equation that we used in solving the problem is stated as
miles per gallon= total distance/total gallon sused
In 1959, Russia sent the Luna 1 spacecraft towards the moon. It made 3.8x10 to the 5th power kilometer trip to the moon in 2.16x10 to the 3rd minutes. Write and expression for the speed of Luna 1 in kilometers/minute. Represent this expression as a quotient of two numbers expressed in scientific notation
The distance between Earth and the moon is 3.8 x 10^3 Kilometers. The time taken to travel this distance was 2.1 x 10^3 Minutes.
The formula to calculate speed is Speed = distance/time.
So, the speed of Luna I was 3.6 x 10^3 / 2.1 x 10^3 Kilometers/Mintues.

Distance Equation Solution:
d=(−3−(−8))2+(4−7)2
√d=(−3−(−8))2+(4−7)2
d=(5)2+(−3)2
√d=(5)2+(−3)2
d=25+9

Mr Dyson bought 5 gallons of paint. He used 3/4 of the 5 gallons to paint his house.
How much paint did Mr. Dyson use?
A 3 3/4 gallons
B 4 1/4 gallons
C 4 3/4 gallons
D 3 1/4 gallons
Answer:
I think 3 3/4 (A)
Step-by-step explanation:
Each gallon is 20 percent, while 3/4 is 75 percent. Divide 20 by 4, which is the denominator. The answer is 5. Every time you get a 5, that's a 1/4. For example:
25: 1 1/4
30: 1 2/4 (1/2)
35: 1 3/4
40: 2
Now, 75 is between 3 and 4 gallons, but it is lower than 4, so B and C are wrong. Let's do the math again.
65: 3 1/4
70: 3 2/4 (1/2)
75: 3 3/4
Remember, 3/4 is about 75%. which means, A is the answer!

Joe is shown 3 cards marked 2 ,5, and 9, he selects these in random order, to give a three digit score. What is the sum of all possible scores
Answer:
3,552
Step-by-step explanation:
The possible scores are
259, 295,529, 592, 952, 925
These are all the possibilities from his selection. Hence the sum of all possible scores may be computed as
= 259 +295 + 529 + 592 + 952 + 925
= 3,552
the sum of all possible scores is 3,552
The following graph shows function f(x).
What is f(x) when x=3
what is the value of the x in this equation 6x = 54
Answer:
x = 9
Step-by-step explanation:
Given
6x = 54 ( divide both sides by 6 )
x = 9
Answer:
x = 9
Step-by-step explanation:
Another way of doing this is by guessing and checking.
What number multiplied by 6 equals to 54?
Well, we know that 6 x 5 = 30.
6 x 6 = 36
6 x 7 = 42
6 x 8 = 48
6 x 9 = 54
Double Checking by replacing the variable from the equation by 9...
6 x 9 = 54
We can also just put the variable on one side of the equal sign and then move the 6 over with the 54, and also changing the operation from multiplication to division.
Showing you so it makes sense...
6x = 54
6 · x = 54
x = 54 ÷ 6
x = 9

Solve the system using substitution: y + 8x = 10 and 2y - 4x = 40
PLS HURRY I NEED THIS DONE IN 10 MINS. HELP ME ASAP PLEASE
Answer:
Hence x = -1 and y = 18
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
Hence x = -1 and y = 18

A box with a height (x+5) has a square base with side x. A second box with height (x+2) has a square base with side (x+5). If the two boxes have the same volume, find the value of x
Answer :
x = -1.43
Explanation :
As given ,
The first box has a height (x+5) has a square base with side x
So, the Length and Breadth of the box are x and x respectively.
Now,
The volume of first box = Length×Breadth×Height
= (x).(x).(x+5)
= x²(x+5)
⇒The volume of first box = x²(x+5)
Now,
Given that , the second box with height (x+2) has a square base with side (x+5).
So, the Length and Breadth of the box are (x+5) and (x+5) respectively.
Now,
The volume of second box = Length×Breadth×Height
= (x+5). (x+5).(x+2)
= (x+5)²(x+2)
⇒The volume of second box = (x+5)²(x+2)
Now,
Given that, the two boxes have the same volume
⇒x²(x+5) = (x+5)²(x+2)
⇒x² = (x+5)(x+2)
⇒x² = x² + 2x + 5x + 10
⇒x² - x² = 7x + 10
⇒0 = 7x + 10
⇒ 7x = -10
⇒ x = -[tex]\frac{10}{7}[/tex] = -1.43
⇒ x = -1.43
As volume of first box = x²(x+5) = (-1.43)²(-1.43+5) = 7.30 ≈ 7
As volume of second box = (x+5)²(x+2) = (-1.43+5)²(-1.43+2) = 7.26 ≈ 7
At x = -1.43, Volume of both the boxes are same.

What is the solution to the equation m/m+4 +4/4-m = m^2/ m^2- 16 ?
m = 4
m = -2
m = 2
m= 4
The solution to the equation m/(m+4) + 4/(4-m) = m²/ (m²- 16) is m= -4.
What is a quadratic equation?For variable x : ax² + bx + c = 0, where a≠0 is a standard quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution since it is a second-order polynomial equation, which is guaranteed by the algebraic basic theorem.
Given:
Quadratic equation,
m/(m+4) + 4/(4-m) = m²/ (m²- 16)
Simplifying,
{m(4-m) + 4(4+m)}/(4²-m²) = m²/ (m²- 16)
4m - m² + 16 + m² = m²/ (m²- 16) x (-(m²- 16))
-m² + 4m+16 = -m²
4m + 16 = 0
4m = -16
m = -4
Therefore, the value of m is -4.
