Answer:
x= -1.22
Step-by-step explanation:
I think in this case you would be solving for x. So, to start you would expand the 2 out to the (x-3). That would give you 2x-6. Then you would expand the 7 out to the (x+2). That would give you 7x+14. You would then be left with 2x-3+7x+14. You would then combine like terms and get 9x+11. To solve for x you would subtract 11 leaving you with 9x= -11. From there you would divide -11 by 9 and get x= -1.22.

What value of x makes this equation true?
0.6x - 5 = 0.1x + 7
Answer:
x=24
Step-by-step explanation:
0.6x - 5 = 0.1x + 7
add 5 to both sides:
0.6x = 0.1x + 12
take away 0.1x from both sides:
0.5x = 12
divide both sides by 0.5
x = 12÷0.5
x=24

Which problem can be represented by the model?
Help
By using the principles of fractions, we can find out that the models represent the problem 3/4 × 3.
Define fractions?A number that represents a percentage of a whole serves as the mathematical representation of a fraction. Fractions can be thought of as any number, any amount, or a portion of an object.
A pizza that has been cut into eight equal pieces. The notation 1/8, which denotes that we are speaking of one portion out of 8 equally sized portions, can be used to refer to a single portion of the pizza.
It indicates one equal part in eight. Furthermore, it can be written as: 1/8
It will be written as 2/8 if we choose to have 2 portions of the pizza. Similar to how we would write 6/8 as a fraction if we were referring to 6 portions of this pizza.
Now here in the question, 3 parts are selected out of 4.
So that suggests it is 3/4.
As there are 3 circular models, so the representation will be as:
3/4 × 3.

The volume, V, of a rectangular prism is determined using the formula V=lwh, where l is the length, w is the width, and h is the height of the prism.
Using this formula, what is the width of a rectangular prism that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches? Round to the nearest tenth.
0.2 inches
4.5 inches
46.1 inches
414.7 inches
Answer:
4.5inches
Step-by-step explanation:
Given the volume of a prism expressed as:
V =lwh where:
l is the length
w is the width,
h is the height of the prism.
Given
V = 138.24in³
h = 9.6in
l = 3.2in
w = ?
Substitute the given values into the formula to get the width
138.24 = 9.6*3.2*w
138.24 = 30.72w
w = 138.24/30.72
w = 4.5in
Hence the width of the rectangular prism is 4.5inches
The width of the rectangular pyramid that has a volume of 138.24 cubic inches, a height of 9.6 inches, and a length of 3.2 inches is 4.5 inches.
Volume of a rectangular pyramid:v = lwhwhere
l = length
w = width
h = height
v = 138.24 inches³
h = 9.6 inches
l = 3.2 inches
w = ?
138.24 = 9.6 × 3.2 × w
138.24 = 30.72w
w = 138.24 / 30.72
w = 4.5 inches

Pattern: 4, 10, 18, 28, 40, 54, 70, 88, 108, 130
Since the second difference is constant in the pattern above, the algebraic
expression will have degree 2. In an expression of degree 2, the largest
exponent is 2. Therefore, we know that the expression for this pattern must
include n^2. What is the algebraic expression for the nth term in this pattern?
Answer:
The algebraic expression for the nth term in this pattern is n^2 + 3n
Step-by-step explanation:
We want an algebraic expression for the nth term in this pattern.
Like we are told, there must be an expression that includes the term n^2
So therefore;
We need to express each of the terms to include the n^2 term
Kindly note that the n notation will represent the term number of the value we are considering. Let’s take it one after the other.
for 4; 1^2 + 3(1)
For 10; 2^2 + 3(2)
For 18; 3^3 + 3(3)
For 28; 4^2 + 3(4)
For 50; 5^2 + 3(5)
So the nth term will be;
n^2 + 3n

3. Jade is checking one of her zeros to a quadratic function. Her steps are shown. What must be true of this value?
Check = 2
0= (2)2 – 2(2) – 3
0= 4 - 4 - 3
0 -3
Answer:
Option C: since a false statement resulted, it means x = 2 is not a zero.
Step-by-step explanation:
We are told that She is checking the zeros of her quadratic function.
Now the zeros of a quadratic function f(x) are values of that make f(x) = 0. In order words they are basically the roots of the function or the x-intercept.
Now, she has tried x = 2 into her quadratic equation and it didn't yield zero.
Since it yielded -3 and not 0, it means 2 is not a zero of the quadratic function.

Find the indicated conditional probability using the following two-way table
P(Take the bus|Junior)=[?]
round to the nearest hundredth.
Answer:
P(Take the bus|Junior)=0.57
Step-by-step explanation:
Conditional Probability
Is a measure of the probability of the occurrence of an event, given that another event has already occurred. If event B has occurred, then the probability that event A occurs is given by:
[tex]{\displaystyle P(A\mid B)={\frac {P(A\cap B)}{P(B)}}}[/tex]
Where [tex]P(A\cap B)[/tex] is the probability that both events occur and P(B) is the probability that B occurs.
The two-way table shows statistics of students and we are interested to find the probability that, given the student is a junior (let's call it event B), they also take the bus (Event A). Thus, the probability we need to calculate is:
[tex]\displaystyle P(A\mid B)={\frac {P(A\cap B)}{P(B)}}[/tex]
Checking on the table, we can see that both events occur when the row and the column of both events coincide, i.e. 20 students out of a total of 100 students in total. Thus:
[tex]\displaystyle P(A\cap B)=\frac {20}{100}=0.2[/tex]
The probability that a student is classified as Junior is
[tex]\displaystyle P(B)=\frac {35}{100}=0.35[/tex]
The conditional probability is:
[tex]\displaystyle P(A\mid B)=\frac {0.2}{0.35}=0.5714[/tex]
P(Take the bus|Junior)=0.57

Answer:
(-7, 5)
Step-by-step explanation:
Since both of them are equal to y, you could just set them equal to each other.
5/7x + 4 = -1/7x - 2
6/7x = -6
x = -7
Now just plug x back to one of the equations:
y = -1/7*(-7) - 2 = 7 - 2 = 5
Therefore, the solution to the system is (-7, 5)
