Answer:
239.556
Step-by-step explanation:
Difference of ratio=9-5=4
Sum of ratio=9+5=14
we know that Eric got $56 more
which means
4/14=56
1/14=56/4
1/14=14
1=14*14
=196
now we need to find
9/14=(196*14)/9
= 239.556
What is the value of x in the equation 2(x-4) = 4(2x + 1)?

1
4.
2
Answer:
The value of x is -2.
Step-by-step explanation:
First, you have to eliminate the brackets by expanding :
[tex]2(x - 4) = 4(2x + 1)[/tex]
[tex]2x - 8 = 8x + 4[/tex]
Next, you have to move all the like-terms to one side :
[tex]2x - 8 - 8x = 4[/tex]
[tex] - 6x = 4 + 8[/tex]
[tex] - 6x = 12[/tex]
[tex]x = 12 \div ( - 6)[/tex]
[tex]x = - 2[/tex]
Answer:
[tex]x = - 2[/tex]
Step-by-step explanation:
[tex]2(x - 4) = 4(2x + 1) \\ 2x - 8 = 8x + 4 \\ 2x - 8x = 8 + 4 \\ - 6x = 12 \\ \frac{ - 6x}{ - 6} = \frac{12}{ - 6} \\ x = - 2[/tex]

If c is a constant such that x^2+100x+c is equal to the square of a binomial, then what is c?
Answer:
c = 2500
Step-by-step explanation:
[tex]x^2+100x + c\\x^2+2\times 50\times x + (50)^2\\=x^2+2\times 50\times x + 2500\\=x^2+100 x + 2500\\equating \: it \: with\: \\x^2+100x + c\\we\; find:\\c = 2500[/tex]
Answer:
c = 2500
Step-by-step explanation:
x² + 100x + c where c = ?
100 x : 100x / 2x = 50

could you use the formula for the surface area of a rectangular prism to find the surface area of a cube explain please help me.
Answer:
You can use our formula for the surface area of a rectangular prism for a cube as well. A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

Find the value of x in the triangle
Answer:
x =3.
Step-by-step explanation:
This is an isosceles triangle so the 2 sides opposite the equal angles are congruent.
So 3x + 2 = 11
3x = 9
x = 3.
Answer:
49 and 2/3
Step-by-step explanation:
3x+2+18+11=180
3x+31=180
3x=149
x=49 and 2/3

There is a point $A$ with positive coordinates such that the sum of the coordinates of $A$ is $14$. If the $x$-coordinate of $A$ is $a$, then point $P$ is at $(3a, a^2+13a-11)$. If the slope of a line passing through $A$ and $P$ is $7$, find $a$.
Answer:
The x-coordinate of A is:
a = 6.1
Step-by-step explanation:
For point A:
x-coordinate = a
x-coordinate + y-coordinate = 14
y-coordinate = 14 - x-coordinate
y-coordinate = 14 - a
So point A can be written as (a, 14-a)
Let (a,14) be (x₁,y₁)
Point P can be written as (3a, a²+13a-11)
Let P be (x₂,y₂)
Slope of a line passing through 2 point is given as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m=7
Substitute all values
[tex]7=\frac{(a^2+13a-11)-(14-a)}{3a-a}\\7=\frac{a^2+13a-a-11-14}{3a-a}\\7=\frac{a^2+12a-25}{2a}\\14a=a^2+12a-25\\a^2-2a-25=0\\a=6.1,a=-4.1[/tex]
As A has only positive coordinates
a = 6.1

A circle is centered at the point (-7,-1) and passes through the point (8, 7).
The radius of the circle is
units. The point (-15,
) lies on this circle.
Reset
Next
Answer:
17 units
Step-by-step explanation:
The radius r is the distance from the centre of the circle to a point on it.
To calculate r use the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 7, - 1) and (x₂, y₂ ) = (8, 7)
r = [tex]\sqrt{(8+7)^2+(7+1)^2}[/tex]
= [tex]\sqrt{15^2+8^2}[/tex]
= [tex]\sqrt{225+64}[/tex]
= [tex]\sqrt{289}[/tex]
= 17

Rita pumped 42 gallons of water into her pool. This was done over a period of 6 minutes at a constant Rate. What was the change in the amount of water in the pool each minute
Answer:
7 Gallons every minute
Step-by-step explanation:
We know that a total of 42 gallons of water was pumped for 6 minutes at a constant rate. Constant rate means that it will always pump the exact same amount of water each time. Eince its at a constant rate we just need to find out how much water was poured over the course of a minute, which can be done by dividing 6 (minutes) by 42 (gallons of water) = 7 gallons of water.

What is the length of the hypotenuse of the triangle
18 units
1872 units
36 units
36/7 units
Answer:
[tex]\large \boxed{36\sqrt{2}\text{ units}}[/tex]
Step-by-step explanation:
Assume ∆DEF looks like the one below.
We can use Pythagoras' Theorem to find the hypotenuse f.
[tex]\begin{array}{rcl}d^{2} + e^{2} & = & f^{2}\\36^{2} + 36^{2} & = & f^{2}\\f^{2} & = & 2 \times 36^{2}\\f & = & \sqrt{2 \times 36^{2}}\\& = & 36\sqrt{2}\\\end{array}\\\text{The length of the hypotenuse is $\large \boxed{\mathbf{36\sqrt{2}}\textbf{ units}}$}[/tex]

Answer:
x=-4
Step-by-step explanation:
Ohhh you wrote 4 on the other post, not 4x.
Okay.
6(x+3)-4x=10
6x+18-4x=10
2x=-8
x=-4
Answer:
The value of [tex]x[/tex]:
[tex]x = -4[/tex]
Step-by-step explanation:
Solve for [tex]x[/tex]:
[tex]6(x+3) - 4x = 10[/tex]
Use Distributive Property:
[tex]6(x+3) - 4x = 10[/tex]
[tex]6x + 18 - 4x = 10[/tex]
Combine [tex]6x[/tex] and [tex]-4x[/tex] together:
[tex]6x + 18 - 4x = 10[/tex]
[tex]2x + 18 = 10[/tex]
Subtract both sides by [tex]18[/tex]:
[tex]2x + 18 - 18 = 10 -18[/tex]
[tex]2x = -8[/tex]
Divide both sides by [tex]2[/tex]:
[tex]\frac{2x}{2} = \frac{-8}{2}[/tex]
[tex]x = -4[/tex]
So, therefore, the final answer is [tex]x = -4[/tex] .

write the equation you would use to find x, then solve for x.
Answer:
x + 6x+10 + x+2 = 180
x = 21
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x + 6x+10 + x+2 = 180
Combine like terms
8x + 12 = 180
Subtract 12 from each side
8x+12-12 = 180-12
8x =168
Divide each side by 8
8x/8 = 168/8
x =21
Answer:
Step-by-step explanation:
by angle sum property of a triangle ,
x+x+2+6x+10=180
8x =180-12
8x =168
x =168/8
x=21
