How does x = 0.7x + 24 equal 80?
Answer:
x=0.7x+24
We move all terms to the left:
x-(0.7x+24)=0
We get rid of parentheses
x-0.7x-24=0
We add all the numbers together, and all the variables
0.3x-24=0
We move all terms containing x to the left, all other terms to the right
0.3x=24
x=24/0.3
x=80
And that's how you get 80
Step-by-step explanation:
i hope this helps. :)
Answer: x = 80
Step-by-step explanation:
80 - 24 = 56
56 divided by 0.7 = 80
A 5 foot tall pole casts a 3 1/3 foot shadow. At the same time an oak tree casts a 20 foot shadow. How tall is the tree?
Answer:
30 feet tall
Step-by-step explanation:
Set up a proportion where x is the height of the tree
[tex]\frac{5}{3\frac{1}{3} }[/tex] = [tex]\frac{x}{20}[/tex]
Cross multiply and solve for x:
100 = 3[tex]\frac{1}{3}[/tex]x
30 = x
So, the tree is 30 feet tall
Write an equation of the line that passes through the point (-12, 6) and is parallel to the graph of the equation y=-1/6x + 1. Explain your reasoning.
Answer:
y=-1/6x+4
Step-by-step explanation:
In order to pass that point, you have to move the line up 4 points. So you make the 1 at the end to 4.

Answer:
7/10
Step-by-step explanation:
1/10 = 2/20
1/4 = 5/20
2/5 = 8/20
11/20 = 11/20
We can see that the next term is just 11/20 + 3/20, as 3/20 is added onto each of the next terms.
11/20 + 3/20 = 14/20, which can be simplified to 7/10.
Hope this helps!
What is (f*g)(x) f(x) = - x ^ 2 g(x) = x + 1
Answer:
Purplemath
First you learned (back in grammar school) that you can add, subtract, multiply, and divide numbers. Then you learned that you can add, subtract, multiply, and divide polynomials. Now you will learn that you can also add, subtract, multiply, and divide functions. Performing these operations on functions is no more complicated than the notation itself. For instance, when they give you the formulas for two functions and tell you to find the sum, all they're telling you to do is add the two formulas. There's nothing more to this topic than that, other than perhaps some simplification of the expressions involved.

Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).
To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.
(f + g)(x) = f (x) + g(x)
= [3x + 2] + [4 – 5x]
= 3x + 2 + 4 – 5x
= 3x – 5x + 2 + 4
= –2x + 6
(f – g)(x) = f (x) – g(x)
= [3x + 2] – [4 – 5x]
= 3x + 2 – 4 + 5x
= 3x + 5x + 2 – 4
= 8x – 2
(f × g)(x) = [f (x)][g(x)]
= (3x + 2)(4 – 5x)
= 12x + 8 – 15x2 – 10x
= –15x2 + 2x + 8

Answer:
6x + 2
Step-by-step explanation:
The area of a square is side length times itself.
In this problem, the area of one square is:
x², or x * x. So the side length of each square must be x.
In the rectangular shape, the area would be top * side. The side is equal to x because "side" is equal to the sides of the other squares (because a square's sides are all the same).
Plugging that into the equation, top * x = x, so the top must be 1.
There are 5 "full-length sides" on the two "full" squares on the left. Then, in the last skinny rectangle, there are two "tops", and one "full-length side".
Substitue the values of each side.
5x + 1 + 1 + x = 6x + 2
Hope this helps! If you have any questions, feel free to ask.

Answer:
4/5
Step-by-step explanation:
8/15 = 8/15
3/5 = 9/15
2/3 = 10/15
11/15 = 11/15
We see that the pattern is that the terms increase by 1/15 as they move up.
Thus, the next term in the sequence is 12/15, which can be simplified to 4/5.

The lengths of the diagonals of a rhombus are 4x and 6x. What expression gives the perimeter of the rhombus?
Answer:
Expression gives the perimeter = 4x√17
Step-by-step explanation:
∵ The diagonals of the rhombus ⊥ to each other and
bisects each other
∴ Half the longest diagonal = 8x/2 = 4x
∴ Half the shortest diagonal = 2x/2 = x
Use Pythagoras theorem to find the length of the side of the rhombus
∴ The length of the side = √[(4x)² + (x)²] = √[16x² + x²] = √(17x²)
∴ S = x√17
∵ Perimeter of the rhombus = 4 × S
∴ P = 4 × x√17 = 4x√17
Answer:
the correct answer is 4x✓13.
Casey wants to buy a gym membership. One gym has a $70 joining fee and cost $35 per month. Another Jim has no joining fee and cost $70 per month. when would Casey pay the same amount to be a member of either gym? How much would he pay?
Answer:
same amount at 2 months. he'd pay 140.
Step-by-step explanation:
35(month) +35(month) =70(joining fee). 70+70=140. that's two months at the first gym.
the second gym is also 140 for the two months because each month is $70. and 70+70=140

Find the surface area of a cuboid with lengths 28 cm,
4 cm and 5 cm. If the answer is A cm2 then
write the value of A.
PLEASE HELP ME OMG X
Answer:
Answer: 544
Step-by-step explanation:
The Surface Area of a Cuboid
Given a cuboid (rectangular prism) of dimensions x,y, and z, the surface area is calculated as follows:
[tex]S=2(xy+yz+xz)[/tex]
The dimensions of a given cuboid are x=28 cm, y=4 cm, z=5 cm, thus:
[tex]S=2(28*4 + 4*5+ 28*5)[/tex]
[tex]S= 2*272 = 544[/tex]
The surface area is [tex]544 cm^2[/tex]
