30x - 16 = 14
Answer:
Step-by-step explanation:
Here you go mate
Step 1
30x-16=14 Equation/Question
Step 2
30x-16=14 Simplify
30x-16=14
Step 3
30x-16=14 Add 16 to sides
30x=30
Step 4
30x=30 Divide sides by 30
answer
x=1
Hope this helps
Step-by-step explanation: To solve for X, we'll need to move all terms that don't contain X to the right and solve.
1. Add 16 to both sides
30x - 16 + 16 = 14 + 16
30x = 30
2. Divide both sides by 30
[tex]\frac{30x}{30} =\frac{30}{30}[/tex]
Therefore, your answer is 1.

In the equation f(x) = 3(x – h) 2+ k, what does (h,k) tell?
Answer:
(h,k) shows the coordintes of the turning point.
Answer:
coordinates of the vertex
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = 3(x - h)² + k ← is in vertex form
with vertex = (h, k )
A building block has a square base that has a perimeter of (12x-9) inches. Explain how to use the expression to find the length of the wall.
Answer:
#of blocks in a single layer of the wall * 3(x)-9/4
Step-by-step explanation:
So, let Y be the length of the wall. It will be made from the building blocks described.
If the perimeter of a square block is 12x-9 and the formula for the perimeter of a square is 4s (where s = length of a side). Then one side of the square is the perimeter divided by 4.
s = (12x-9)/4 = 3x-9/4
In order to find the length of the wall, multiply s by the number of blocks used to build one level of the wall.
The length of the wall is n×(3x-9/4)
What is the perimeter of a square?The perimeter of a square is defined as the length that its boundary covers. The formula to calculate the perimeter of a square is given as: P = 4 × side.
Given:
The perimeter of the square base = 12x-9 inches
As we know the Perimeter of the square = 4×side
Equating both we get
4× length of the square base = 12x-9
length of the square base = (12x-9)/4
length of the square base = 3x-9/4 inches
and depending on the number of blocks say n the length of the wall will be = n×(3x-9/4)
Hence the length of the wall = n×(3x-9/4)

Tell whether the equation has one, zero, or infinitely many solutions.
8(x-4) + 19 = 8x - 13
Answer:
This problem has infinite many solutions.
Step-by-step explanation:
8(x−4)+19=8x−13
Step 1: Simplify both sides of the equation.
8(x−4)+19=8x−13
(8)(x)+(8)(−4)+19=8x+−13(Distribute)
8x+−32+19=8x+−13
(8x)+(−32+19)=8x−13(Combine Like Terms)
8x+−13=8x−13
8x−13=8x−13
Step 2: Subtract 8x from both sides.
8x−13−8x=8x−13−8x
−13=−13
Step 3: Add 13 to both sides.
−13+13=−13+13

The profits of a company are found by subtracting the company's costs from its revenue. If a company's cost can be modeled by 10x + 130,000 and its revenue can be modeled by
50x -0.00047x^2
, what is an expression for the profit?
9514 1404 393
Answer:
P = -0.00047x^2 +40x -130,000
Step-by-step explanation:
Profit is found by subtracting the company's costs from its revenue.
P = R - C
P = (50x -0.00047x^2) -(10x + 130,000)
P = -0.00047x^2 +40x -130,000
You and 3 friends decide to split a box
of one dozen donuts. Together, the
amount spent for the donuts is $17.45. If it costs $1.25 to park, how much did each donut cost per person?
WRITE AN EQUATION and solve.
Please hurry
Thx
Answer:
Step-by-step explanation:
Number of individuals = 4
Cost of dozen donuts with transport = $17.45 + $1.25
= $18.7
Since there are 12 pieces in a dozen pack of donuts, then the amount of each donut is:
= $18.7/ 12
= $1.56
So, if four people share a dozen donut, each person will have:
= 12/4
= 3 donuts each
and the price each person will pay for the three donuts will be:
= $1.56 × 3
= $4.68

the measure of angle 2 = (3x+11)º, find the measure of each angle.
X =
angle 1 =
angle 2 =
- linear pairs are supplementary, meaning they add up to 180°
5x + 9 + 3x + 11 = 180
8x + 20 = 180
8x = 160
x = 20
- now plug in.
angle 1: 5(20) + 9 = 100 + 9 = 109°
angle 2: 3(20) + 11 = 60 + 11 = 71°

What is this i need help asap plz plz really quicjkly
Answer:

Step-by-step explanation:
To compute a log that doesn't have a base of 10 you use the following formula
Log(number)/Log(base)
We can use this formula to compute the numbers with no variables
Log₃18= Log(18)/log(3) which gives us around 2.63
We can then compute the first part of the right side 2*log₃6 which can be rewritten as 2*(log(6)/log(3)) which gets us around 3.26
After computing this we can rewrite it all as 2.63=3.26-(.5*log₃x)
This is pretty easy to solve from here and we start by subtracting 3.26 from both sides which gives up
-.63=.5*log₃x
Dividing both sides by negative one half (or .5) gives us
1.26=log₃x
You then can use a special rule to rewrite this equation
3^1.26=x
This gives us 3.99 which is pretty much 4
Cody works at a car dealership where he earns $300 each week plus a commission equal to 1% of his total sales. This week his goal is to earn at least $500. What is the minimum amount of total sales Cody must have to reach his goal?
Answer:
$20,000 = sales
Step-by-step explanation:
Giving the following information:
Fixed salary= $300
Commission rate= 1% of sales
First, we need to establish the net income formula:
Net income= 300 + 0.01*sales
Now, the sales required for $500 net income:
500= 300 + 0.01sales
200/0.01 = sales
20,000 = sales
Prove:
Net income= 300 + 0.01*20,000
Net income= $500

3.3 x 10^5 + 44,000 = ?
Answer:
3.74 x 10^5
Step-by-step explanation:
First expand the term in scientific notation into normal notation.
3.3 x 10^5 - Here the ^5 tells us to move the decimal five places to the right, so we go from
3.30000 to
330000.00
So 3.3 x 10^5 = 330,000
Now add that to 44,000 and you get 374,000.
Return this number to scientific notation. Move the decimal back to its spot before the 3. We go from
374,000.00 to
3.74000
Once again the decimal has moved five places, so that is the number in the exponent of the our scientific notation, and therefore our answer is
3.74 x 10^5

Answer:
16 pieces of ribbon
Step-by-step explanation
if you divide the length of the ribbon by the length of the pieces she needs to cut it into, you get 16.
