If 5/x = 15/x+20, what is the value of x/5?
Answer:
c) 2
Step-by-step explanation:
here you can use cross multiplication. that's where you turn the fraction into an equation. ( there's videos about it, I'm not very good at explaining )
so you can turn
[tex]\frac{5}{x} = \frac{15}{x + 20}[/tex]
into
5(x + 20) = 15x
5x + 100 = 15x
subtract 5x from both sides
100 = 10x
x = 10.
the value of x/5 would be 2, since 10/5 is 2.
Since x/5 is the reciprocal of 5/x, we know that we can flip the fraction on the right hand side will be flipped.
Thus, x/5 = (x + 20)/15
Now we cross multiply, 15x = 5(x + 20)
Simplify: 15x = 5x + 100
Subtract 5x from each side: 10x = 100
Divide 10: x = 10
Now plug 10 back into the right hand side: (10 + 20)/15
So, the answer is 2.

Alicia bought two slices of pizza and a bottle of juice for $4.95. The juice was $1.65. How much is one slice of pizza?
Subtract the price of the juice from the total then divide the remaining amount by 2:
4.95 - 1.65 = 3.30
3.30 /2 = 1.65 per slice.
Ralph drove 272 miles in 4 hours. What was his average
speed? (per single hour – unit rate)PLEASE HELP MEE
answer: 68
work:
all you basically do is just divide 272 by 4
If Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed
What is Division?
A division is a process of splitting a specific amount into equal parts.
Given that Ralph drove 272 miles in 4 hours
We need to find his average speed
The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time
Speed=Distance/ Time
Average speed=272/4
=68 miles per hour
Hence, if Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed

15. A music store sells a copy of a deluxe electric guitar for $295. This is $30 more
than 1/3 the cost of the actual deluxe guitar it is modeled after. What is the cost
of the deluxe electric guitar? Find your solution below. Type the code in exactly.
(ALL CAPS, NO SPACES). Example: If my answer was -76.1 l would type in KHGLB
Answer:
It costs $795
Step-by-step explanation:
$30 more than one half so you have to subtract 30 from 295 then that's 265 which is 1/3 of the acual price. So then you have to multiply 265 by 3 then you get $795.

Answer:
-3, 25, 53
Step-by-step explanation:
f(x) = 4x + 9
f(-3) = 4(-3) + 9
f(-3) = -12 + 9
f(-3) = -3
f(4) = 4(4) + 9
f(4) = 16 + 9
f(4) = 25
f(11) = 4(11) + 9
f(11) = 44 + 9
f(11) = 53

Let
f(x) = {3x - 7}/{x + 1] Find the range of f.
Give your answer as an interval.
Answer: Range = (-∞, 3) U (3, ∞)
Step-by-step explanation:
The range is the set of all y-values in a function. The easiest and most straightforward way to find the range is to graph the function and find asymptotes, or locations on the graph where the function lacks y-values.
You can plug in a few points to the equation, as shown in this table below.
After you have your points, you can draw your function following the points, as shown in the next image. Notice the line at y = 3, where the function does not cross. Although it will get infinitely close to the line, the function will never meet or cross this point at any x-value. This is what is known as a "horizontal asymptote", and is not included in the range of the function.
We can represent this asymptote in a range, which is a representation of all possible y-values in the function. The possible y-values for this function start at negative infinity and end at infinity, but do not exist at y = 3, so we represent this through this mathematical expression:
Range = (-∞, 3) U (3, ∞)
The black graph is the graph of y = f(x). Choose the equation for the red graph. A. y + 4 = f(x) B. y - 4 = f(x) C. y = f(x - 4) D. y = f(x + 4)
The right equation of the red line will be f(x)=y-4 if the equation of the black line is f(x)=y
What is the equation?
The equation is like a relationship between variables.
What is a variable?A variable is anything which have a value.
How to form an equation?
If we see the points of red line and the lack line we can see the value of x in black line is 4 greater than red line so the equation will be

What is the equation of
Slope is 0, y - intercept is 5
With the equation 3z+3=2z+6
Answer:
z = -3
Step-by-step explanation:
Simplifying
3z + -3 = 2z + -6
Reorder the terms:
-3 + 3z = 2z + -6
Reorder the terms:
-3 + 3z = -6 + 2z
Solving
-3 + 3z = -6 + 2z
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-2z' to each side of the equation.
-3 + 3z + -2z = -6 + 2z + -2z
Combine like terms: 3z + -2z = 1z
-3 + 1z = -6 + 2z + -2z
Combine like terms: 2z + -2z = 0
-3 + 1z = -6 + 0
-3 + 1z = -6
Add '3' to each side of the equation.
-3 + 3 + 1z = -6 + 3
Combine like terms: -3 + 3 = 0
0 + 1z = -6 + 3
1z = -6 + 3
Combine like terms: -6 + 3 = -3
1z = -3
Divide each side by '1'.
z = -3
Simplifying
z = -3
Answer:
=3z+3=2z+6
=3z-2z=6-3
=z=3

For every 15 students who run track, there are 7 students who play baseball. There are 112 more students who run track than play baseball. How many students run track? How many students play baseball? Select your answers from the drop-down lists.
Answer:
210 students run track and 98 students play baseball
Step-by-step explanation:
For every 15 students who run track there are 7 students who play baseball
There are 112 more students who run track than play baseball
Let y represent the various groups of students
15 × y= 15y
7 × y= 7y
15y - 7y = 112
8y = 112
Divide both side by the coefficient of y which is 8
8y/8 = 112/8
y= 14
Therefore the number of students that run track is
= 15 × 14
= 210
The number of student that play baseball is
= 7 × 14
= 98
Hence 210 students run track and 98 students play baseball

given g(x)=0.5x^2-5x+3.5, find g (4a)
Answer:
g(4a) = 8a^2 -20a +3.5
Step-by-step explanation:
Put 4a where x is and simplify.
g(x) = 0.5x^2 -5x +3.5
g(4a) = 0.5(4a)^2 -5(4a) +3.5
= 0.5(16a^2) -20a +3.5
g(4a) = 8a^2 -20a +3.5
