Step-by-step explanation:
Write the statement as an equation Anumber decreased by six is five more than twice the number.
let the numbers be x
x-6-5=2x
Answer:
x - 6 = 2x + 5
Step-by-step explanation:
Let's break down the statement.
A number decreased by six means a number/variable subtracted by six. So, we have x - 6.
Five more than twice a number means five plus two times a number/variable. So, we have 2x + 5.
The 'is' in the middle of the statement signifies that they are equal to each other.
The equation would be x - 6 = 2x + 5.
Hope that helps.

Madonna loves records. She has 338 of them. Her grand father gives her some for her birthday. She ends up with 456 after her birthday. At what percent did her grandfather give her. (I know it's a funky question. You have to divide the amount and then round it to the nearest hundred)
Answer:
34.9%Step-by-step explanation:
Ok, we need to express this number as a percent of increase. So, what we'll do is write this as a proportion.
456/338 = x/100
456 x 100 = 338x
45600 = 338x
x = 134.911242604
A 34.9% increase
Answer:
17.53%Step-by-step explanation:
Initial number = 388Final number = 456Increase in number:
456 - 388 = 68Increase in percent:
68/388*100% = 17.53% rounded to the nearest hundredsRewrite the following expression in logarithmic form:
2^9=512
Answer: log(2) 512= 9
Step-by-step explanation:
A P E X ;)
In logarithmic form, the expression [tex]2^9 = 512[/tex] can be rewritten as follows:
[tex]log_{(2)}\ 512 = 9[/tex]
As we know that the logarithmic form allows us to express the exponent as the logarithm of the base to a certain value, which in this case is 9.
To understand this, let's break down the expression.
The base of the logarithm is 2, and the result of raising 2 to the power of 9 is 512.
By taking the logarithm of 512 to the base 2, we get the exponent, which is 9.
So, in logarithmic form can be written as:
[tex]log_{(2)}\ 512 = 9[/tex]
Therefore, in logarithmic form, the expression [tex]2^9 = 512[/tex] can be rewritten as follows:
[tex]log_{(2)}\ 512 = 9[/tex]

These points are linear. Find the slope.
Answer:
Slope = 3/2
Step-by-step explanation:
The slope of an equation is rise/run, or y/x.
Since the graph indicates that y rises by 3 and x rises by 2, the slope would be 3/2
Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points. I will be calculating the slope using the two points (2, 3) and (4, 6).
Slope = [tex]\frac{rise}{run}[/tex]
= [tex]\frac{6-3}{4-2}[/tex]
= [tex]\frac{3}{2}[/tex]

2.3a+3.5b-1.8a-2.7b simplify. Show work.
Answer:
a = -1.6b
Step-by-step explanation:
Simplifying
2.3a + -1.8a + 3.5b + -2.7b = 0
Combine like terms: 2.3a + -1.8a = 0.5a
0.5a + 3.5b + -2.7b = 0
Combine like terms: 3.5b + -2.7b = 0.8b
0.5a + 0.8b = 0
Solving
0.5a + 0.8b = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-0.8b' to each side of the equation.
0.5a + 0.8b + -0.8b = 0 + -0.8b
Combine like terms: 0.8b + -0.8b = 0.0
0.5a + 0.0 = 0 + -0.8b
0.5a = 0 + -0.8b
Remove the zero:
0.5a = -0.8b
Divide each side by '0.5'.
a = -1.6b
the absolute value of 15.3 is the opposite of 15.3?
Answer:
No. The absolute value of 15.3 is 15.3, not the opposite.
Step-by-step explanation:
Absolute value makes any number its positive form. For example -2 in absolute form is 2. So 15.3 in absolute form is still positive 15.3.

What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have line graph from which we can consider two points as (1, 4) and (3, 12).
So, the slope of line
m = (12 - 4)/ (3-1)
m= 8/ 2
m= 4
Now, using slope intercept form
y= mx+b
y= 4x + b
Now, put x= 1 and y=4 in above equation
4 = 4 + b
b= 0
So, the Equation of line is y= 4x.

A random Gaussian process x has a mean of 2.5 and variance of 0.36. Calculate the probability of the random variable having a value less than 3.
Answer: 0.79758
Step-by-step explanation:
Given that :
Mean (m) = 2.5
Variance = 0.36
Thw standard deviation = sqrt(variance) = sqrt(0.36) = 0.6
The probability of the random variable having a value less than 3 is obtained by:
P(x < 3)
Using the relation to obtain the standardized Zscore :
Z = (x - m) / s
Z = (3 - 2.5) / 0.6
Zscore = 0.8333333
p(Z < 0.833) = 0.79758 ( Z probability calculator)

If QRST is a kite, find the measure of QRS
Answer:
!!!!
137°
i took the test and that was the right answer.
Step-by-step explanation:
QRST is a kite therefore, the value of angle QRS in the kite is 137 degrees.
Properties of a kiteOne pair of opposite angles is equal.Diagonals are perpendicular to each other.The sum of angles in the kite is 360 degrees.
Therefore,
79 + 79 + 11x - 6 + 4x + 13 = 360
158 - 6 + 13 + 11x + 4x = 360
158 + 7 + 15x = 360
15x = 360 - 158 - 7
15x = 195
divide both sides by 15
x = 195 / 15
x = 13
Therefore,
∠QRS = 11(13) - 6 = 143 - 6 = 137 degrees.
