A video rental store charges a $20 membership fee and $2.50 for each video rented.
Write a linear equation to model this situation.
Tell what each variable represents.
Answers
Answer:
2.5x + 20 = y
Step-by-step explanation:
first, assign a variable to each unknown:
since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y
x = number of videos rented
y = total cost
so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.
So, the equation is 2.5x + 20 = y

Answer:
No, the triangles are not similar.
Step-by-step explanation:
For ΔNOP, since all triangles' angles equal 180°, to find the missing angle you subtract the given angles from 180
180-70=110, 110-58=52 ∠N = 52°
since ΔQRS does not have any angle measures of 58° or 52°, the triangles are not similar becasue similar triangles have congruent angles.

What percent of 120 is 42?
can you show your work, please
Answers
42:120*100 =
(42*100):120 =
4200:120 = 35
Now we have: 42 is what percent of 120 = 35
Question: 42 is what percent of 120?
Percentage solution with steps:
Step 1: We make the assumption that 120 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=120$100%=120.
Step 4: In the same vein, $x\%=42$x%=42.
Step 5: This gives us a pair of simple equations:
$100\%=120(1)$100%=120(1).
$x\%=42(2)$x%=42(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{120}{42}$
100%
x%=
120
42
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{42}{120}$
x%
100%=
42
120
$\Rightarrow x=35\%$⇒x=35%
Therefore, $42$42 is $35\%$35% of $120$120.
42/120 = 0.35
0.35 x 100 = 35%

Perla buys the star necklace that is originally $49.95 but is currently on sale for 62% off. If she gets an additional 20% off, what is the final price of the necklace?
Answers
Answer:
Step-by-step explanation:
Remark
It's not 82.
You have to take the 62% off and then follow it with 20% from the new price.
Solution
62%
If you get a reduction of 62%, it means that you pay 100% - 62% = 38% of the marked price of $49.95.
38% price =49.95 * 62/100
38% price = 3096.9 / 100
38% price = $30.97
20% Reduction
20% more means that you pay 100% - 20% = 80%
20% more reduction = 30.97 * 80/100
20% more reduction = 2478/100
20% more reduction = 24.78
Conclusion.
Your final price before taxes is $24.78

What is the equation of the line that passes through the point (-8,-6) and
has a slope of 1/4
Answers
Answer:
y = 1/4x -4
Step-by-step explanation:
Since you know that that slope int. equation is y = mx+b, and the m is the slope just plug in the slope in the equation. So it will be y = 1/4x + b.
Then what you will do is solve for b in the equation. So what you do is plug in the x and y value from the coordinate given in the equation, so it will be like this: -6 = 1/4(-8) +b
-6 = -2 +b
-4 = b
b = -4
So then you plug back the b value into the equation with slope to wtite the equation. So it would be, y = 1/4x -4

Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it
Answers
Answer:
Step-by-step explanation:
First use distributive property: a(b + c) = a*b + a*c
3n - 6 = -8(6 + 5n)
3n - 6 = 6 * (-8) + 5n *(-8)
3n - 6 = -48 - 40n
Now add 40n to both sides
3n - 6 + 40n = -48 - 40n + 40n
43n - 6 = -48
Now add 6 to both sides
43n - 6 + 6 = -48 + 6
43n = -42
n = -42 /43
Answer:
0.98
Step-by-step explanation:
3n-6=-8(6+5n)
3n-6=-48-40n
3n=-48-40n+6
40n+3n=-42
43n=-42
n=0.98 (I rounded it)

The triangular prism above has been created with two equilateral triangles and three congruent rectangles the height of the triangle is 3.5 inches find the surface area of the triangular prism
Answers
Answer:
108 inches square.
Step-by-step explanation:
Here
base= b= 4 inches
height = h=w= 3.5 inches
and length = l= 9 inches
The surface area is the total area of all the sides of the prism. So the area of the 2 triangles is given by
Area of the 2 Δs= b* h= 4*3.5= 13.5 inches square
Area of the 3 rectangles = l*w(3)= 3( 9*3.5)= 94.5 inches square.
Total area = 13.5 + 94.5 = 108 inches square
This can be found by applying another formula.
Surface area of the triangular prism = bh + ( s1+s2+s3) H
= 4*3.5 + (9+9+9)3.5
= 13.5 + 94.5= 108 inches square.
where H is the width of the recatngles which is equal to the height of the triangles.
