3. If 6x + 4 = 20 − 2x, then x = ?
a. 2
b. 6
c. 8
d. 16
e. 24
Answer:
a
Step-by-step explanation:
[tex]6x+4=20-2x[/tex]
Add 2 to each side
[tex]8x+4=20[/tex]
Subtract 4 from each side
[tex]8x=16[/tex]
Divide 8 by each side
[tex]x=2[/tex]
Answer:
a
Step-by-step explanation:
Your goal is to isolate the variable(x). If you subtract 4 from the left side and right side, then you are left with , 6x=16-2x. Then you add 2x to both sides to get 8x=16. Lastly divide both sides by 8 to get x=2. Hope this helps :)
Find the area of the following shapes:
Answer:
Area = 20 square units
Step-by-step explanation:
=> We know that;
Base 1: 3 units
Base 2: 7 units
Height: 4 units
=> Now let's come up with a congruent base first:
[tex]\frac{(3 + 7)}{2}[/tex] = final base
10/2 = final base
5 = final base
=> Finally, Area of the trapezoid:
A = Final Base * Height
A = 5 * 4
A = 20 square units
Hope this helps!

A business owner wants to have the front window of her store painted and is considering two
artists for the job. Tiana has quoted a flat rate of $292 for the job. Denise's quote is $39 per
hour, plus $19 to cover the cost of materials. Depending on how long it takes Denise to paint
the window, these two could end up charging the same amount. How long would Denise have
to take? How much would it cost?
A computer program in Shannon’s computer carries out a single mathematical operation in 1.5 × 10-6 seconds. How much time would the program take to complete 2.5 × 103 mathematical operations?
1/1.5 * 10^-6 = 2500/x
x = 1.5 * 10^-6 * 2500
x = 0.00375 or 3.75 * 10^-3 second.
Help im struggling and its due tommorow need help fast figure out these 2 questions Show work Please NO LInks Dont answer if your not gonna do it please.
Answer:
28. x = 3 31. x = -3
Step-by-step explanation:
4x=12
divide both sides by 4
4x/4 = 12/ 4
x = 3
x/-3 = 1
multiply both sides by -3
x/-3 (-3) = 1 (-3)
simplify both sides
x = -3

There are 30 people entered into a contest. How many ways can the contestants win first, second, third, and fourth place?
Answer:
I am not entirely sure so don't kill me if it's wrong qwq
Step-by-step explanation:
Well assuming P represents the number of outcomes, n the number of competitors and r the number of places to be awarded.
P = n!
(n−r)!
P=30! /
(30-4)!
P=30!/26!
P=657720
Write the equation of the circle with center (0, 0) and (3, 6) a point on the circle.
Answer:
Step-by-step explanation:
We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:
[tex](3-0)^2+(6-0)^2=r^2[/tex] and
[tex]3^2+6^2=r^2[/tex] and
[tex]9+36=r^2[/tex]
Therefore, r-squared is 45, so the circle's equation in standard form is
[tex](x-0)^2+(y-0)^2=45[/tex] or more simply:
[tex]x^2+y^2=45[/tex]

Sara makes some Blue paint. She mixes yellow, red and brown in the ratio 4: 6: 9. He uses 340 ml of the yellow paint. How much Blue paint does he make?
Answer:
1615
Step-by-step explanation:
the equation that represents the amount of yellow paint used =
(ratio of yellow paint / sum of ratios) x p = 340
p = blue paint
4 / 19 x p = 340
p = 1615

Answer:
Option 'a' is the correct answer.
what is the missing exponent?
17 / 17^4 = 17^8
Answer:
The missing exponent is 12.
Step-by-step explanation:
Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.
The only number subtracted by 4 that would give you 8 is 12.
Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.
For example,
[tex]17^4+17^8=17^1^2[/tex]
Therefore, the missing exponent is 12.
Because: [tex]17^1^2/17^4=17^8[/tex]
describe the transformation of f(x) = sin x to g(x) = sin ( x + pi/3)
The function f(x) = sinx will be shift left side by π/3 units and becomes g(x) = sin(x + π/3) and period of the transformed function becomes 2π
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a primary function:
f(x) = sinx and
The transformed function is:
[tex]\rm g(x) = sin(x+\frac{{\pi} }{3} )[/tex]
If we replace x to [tex]\rm x + \frac{\pi}{3}[/tex] it will shift to the left by π/3 units.
For a period of the transformed function is given by:
[tex]\rm T = \frac{2\pi}{n}[/tex]
Where n is used to find the period of the function.
n = 1
t = 2π
Thus, the function f(x) = sinx will be shift left side by π/3 units and becomes g(x) = sin(x + π/3) and period of the transformed function becomes 2π
