Answer:
If both numbers have to stay equivalent, then y equals 30 if x = 12. My reasoning is 12/4 = 3. 3 times 10 = 30.
Solve the system of equations by the substitution method.
y = 5x + 6
y=9x+7.
Answer:
(-1/4, 19/4)
Step-by-step explanation:
5x+6=9x+7
-4x=1
x= -1/4
y=5(-1/4) +6
y=19/4
6 = 2(y+2)
What does y equal?
Answer:
y = 1
Step-by-step explanation:
[tex]\frac{6}{2}=\frac{2(y+2)}{2}\\ \Leftrightarrow 3-2=y=2-2\\\Leftrightarrow y=1[/tex]
The solution to the given equation 6 = 2(y+2) is y = 1, which is determined by distribution and arithmetic operations.
The equation is given as follows:
6 = 2(y+2)
To solve the equation 6 = 2(y + 2) for y, we need to isolate y on one side of the equation.
First, distribute the 2 on the left side by multiplying it with y and 2:
6 = 2y + 4.
Next, move the constant term (4) to the other side of the equation by subtracting it from both sides:
6 - 4 = 2y
2 = 2y
y = 2/2
Apply division operation to get:
y = 1
Therefore, the solution to the given equation is y = 1.

Huilans age is two times Thomas’s age. The sum of their age is 25. What is Thomas age? (Please help)
Answer:
Hulain is 10 and Thomas is 5
Step-by-step explanation:
soooo
add variables
thomas age: t
hulians age: h
h = 2t
15 = t + 2t
umm i dont remember if you can add t and 2t they have the same um variable and power ig. if you can then:
15 = 3t
t = 5
sooo now hulians turn!
h = 2t
h = 2(5)
h = 10
Read the passage.
(1) Ask young people today if they know of anyone who has had smallpox, and they might ask, "What’s smallpox?” (2) That is because this disease was eradicated from the planet decades ago, thanks to vaccinations. (3) Despite the obvious effectiveness of vaccination, opponents of this procedure argue that humans are better off fighting diseases on their own without adding anything potentially harmful to their bodies. (4) Still, the American Academy of Pediatrics says that vaccines can be 99 percent effective, and the Centers for Disease Control claims that, over a 10-year period, vaccines allowed 322 million children to avoid illnesses. (5) So the next time someone tells you that vaccines are poisoned apples that will lead to a fate like Snow White’s, counter their argument with the facts. (6) The bottom line is that vaccines are safe to use and save lives.
How can the writer use understatement in this passage?
by changing the phrase “young people” to “most people” in sentence 1
by deleting the words obvious and potentially from sentence 3
by adding the phrase “so a few lives might be saved” to the end of sentence 4
by shortening the passage to only five sentences by removing sentence 5

Ramona deposits $2,500 into a savings account that pays 4.5% interest compounded annually. If Ramona makes no deposits or withdrawals, how much interest will her money earn after 3 years? Record your answer in the boxes. Then fill in the bubbles. Be sure to use the correct place value.
Answer: She will earn $352.92 as interest.
Step-by-step explanation:
Formula for compound interest[tex]= P((1+r)^t-1)[/tex]
, where P= principal value, r = rate of interest(in decimal) , t= time
As per given , we have
P = $2,500
r = 4.5% = 0.045
t= 3 years
then, Compound interest = [tex]2500((1+0.045)^3-1)=2500((1.045)^3-1)[/tex]
[tex]=2500(1.141166125-1)=2500(0.141166125)\\\\\approx\ \$352.92[/tex]
Hence, she will earn $352.92 as interest.

Two groups of students were asked how far they lived from their school. The table below shows the distances in miles:
Group A (distance in miles) 1 1.5 8 9.2 6.8 4.5 4.8 2.5 0.76
Group B (distance in miles) 2 2.5 3.23 1.3 1.8 2.4 3 1.5 1.8
Which statement best compares the mean distances for the two groups?
It is equal for Group A and Group B.
It is greater for Group B than Group A.
The value for group A is double the value for Group B.
The value for group B is three times the value for Group A.
Answer:
C. The value for Group A is double the value for Group B
Step-by-step explanation:
First, you add all the numbers from each group.
A: The distance in total is 39.06
B: The distance in total is 19.53
To find the mean, which is another way of saying the average, you divide the sum with how many numbers there are. (hope this makes sense, I suck at wording)
A: There are 9 numbers in total, hence, 39.06/9 = 4.34
B: There are 9 numbers in total, hence, 19.53/9 = 2.17
Those are the mean distance for the two groups.
2.17 * 2 = 4.34
Hence, C (third statement)
Answer:
C. Its value for Group A is double the value for Group B.

Working alone, Darryl can oil the lanes in a bowling alley in ten hours. Ming can oil the same lanes in eight hours. Find how long it would take them if they worked together. Round to the nearest tenth.
(Part 1 of asking for help)
Answer:
9.1
Step-by-step explanation:
If Darryl and Ming worked together they takes 4.4 hours to complete the work.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, Working alone, Darryl can oil the lanes in a bowling alley in ten hours. Ming can oil the same lanes in eight hours.
Darryl can oil the lanes in a bowling alley in one hour = 1 /10
Ming can oil the same lanes in one hour = 1 / 8
The time it takes to work together,
1 / t = 1 / 10 + 1 / 8
1 / t = 10+8 / (10 × 8)
1/t = 9 / 40
t = 40/9
t = 4.4 hours
Thus, if Darryl and Ming worked together it takes 4.4 hours to complete the work.

Between 1 and 2, the graph goes over 4 and down 1, so the slope is -1/4
Between 0 and 1, the graph goes over 4 and down 2, so the slope is -2/4 = -1/2
We can see a trend here. For each unit interval farther to the left, the slope doubles. So, we have ...
