Need the answer to this equation
.3a + .8 = .5a - 2
Answer:
14
Step-by-step explanation:
.3a+.8=.5a-2
Subtract. 3a from both sides:
.8=.2a -2
Add 2 to both sides:
2.8=.2a
Multiply both sides by 5:
a=14
Hope this helps!
Answer:
a = 14
Step-by-step explanation:
.3a + .8 = .5a - 2
.3a - .5a = -2 - .8
-.2a = -2.8
a = -2.8/-.2
a = 14

Answer: -8
Step-by-step explanation: First, substitute 8 for y and then solve the remainder of the problem.
-4x - 8 = 24
-4x - 8 + 8 = 24 + 8

what is the correlation coefficient for the data in the table -0.93,-0.27,0.27.0.93
The answer to this question is the letter D.
The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
How to find the correlation coefficient for the data table -0.93,-0.27, 0.27, 0.93?
This is because the correlation coefficient focuses on the linear relationship between two variables.
numbers between -1 and 1 should be one of the values related to the bill. As you can the letter D is the closest and most realistic answer.

Find the value of .
Answer: 25
Step-by-step explanation: In this problem, we're given a diagram and were asked to find the value of x.
Since the two lines in the figure intersect, we know that they form vertical angles and remember that vertical angles are always congruent, or of equal measure.
Therefore, since we know that one angle measures 75° and the other angles measures 3x°, we can setup the equation 75 = 3x.
To get x by itself since 3 is being multiplied by x,
divide both sides of the equation by 3.
On the left, 75 divided by 3 is 25
and on the right, the 3's cancel.
So the value of x in the diagram shown is 25.
Which function has the greater slope and what does it indicate?
Answer:
The math function has the greater slope, which shows that the estimated time per question for math is greater than the estimated time per question for language arts.
OR B on edge
Step-by-step explanation:
The cauliflower function has the greater slope, which shows that the cost per pound of cauliflower is increasing at a faster rate than the cost per pound of broccoli.
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
First, Slope for Broccoli
Slope = (3.6 - 3) / (3 - 2.5)
Slope = 0.6 / 0.5
Slope = 1.2
Second, Slope for Cauliflower
slope = (4.50 - 2.75) / (4.5 - 2.75)
= 1.75 / 1.75
= 1.000
Since the slope of the cauliflower function (1.0000) is greater than the slope of the broccoli function (0.8364), we can conclude that the cauliflower function has the greater slope.

How can you find f(2) if f(x) = -3x2 – 7?
Answer:
-3(2) x 2 -7 = -6x2-7 =-19
Step-by-step explanation:
The value of f(2) for the given function f(x) = -3x² – 7 will be -19.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
As per the given function,
f(x) = -3x² – 7
Put x = 2
f(2) = -3(2)² - 7
f(2) = -2(4) - 7
f(2) = -8 - 7 = -15
Hence "The value of f(2) for the given function f(x) = -3x² – 7 will be -19".

What is the approximate length of the radius, r? Use 3.14 for . Round to the nearest inch.
a
38 inches
b
24 inches
c
12 inches
d
46 inches
Answer:
C 12 inches
Step-by-step explanation:
you get the circumference formula C = 2 *pi *r
then divide 2 from 75 and then pi and then you get your radius
i hope this helped<3
Step-by-step explanation:
a 38 inches
The radius is half of the circumference.
Now lets figure out what we know.
1.Our circumference is 75 inches
We would have to divide 75 by two to get it in half.
75÷2=37.5
Now we round to the nearest inch.
And our answer is 38 inches (A)

The areas of the squares adjacent to two sides of a right triangle are 32 units^2 2 squared and 32 units^2 Find the length, xxx, of the third side of the triangle.
Answer:
8 units
Step-by-step explanation:
If the area of the squares are 32 units^2, we have that:
Area = Side * Side
Side^2 = 32
Side = sqrt(32) = 5.657 units
So as the squares are adjacent to two sides of the triangle, we have that the triangle has two sides of 5.657 units
As it is a right triangle, we can use the Pythagoras' theorem:
c^2 = a^2 + b^2
c^2 = 5.657^2 + 5.657^2
c^2 = 64
c = 8 units

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number = c
We can make an expression as,
c - 13 = -2
Now,
Solve for c.
c - 13 = -2
Add 13 on both sides.
c = -2 + 13
c = 11
Thus,
The value of c is 11.

Step-by-step explanation:
Convert every fraction to an improper fraction just to make it easier.
43/10 - (12/5x + 11/2) = 1/2 (-18/5x + 6/10)
Distribute.
= 43/10 -12/5x - 11/2 = -18/10x + 6/10
Simplify using the common denominator, which is 10.
43/10 - 24/10x - 55/10 = -18/10 + 6/10
Isolate the x.
-24/10x + 18/10 = -43/10 + 55/10 + 6/10
Simplify.
-6/10x = 18/10
Multiply by the reciprocal (basically dividing fractions)
