Answer: 17
Step-by-step explanation:
In this problem, the phrase "a number" can be interpreted as a variable. In this case, let the variable be "x."
Thus, "twice a number" = "2x"
"and 13" = "+ 13"
"is 47" = "= 47"
Thus, the problem is simply 2x + 13 = 47.
Then, simply subtract 13 from both sides to get 2x = 34.
Then, simply divide both sides by 2 to get x = 17.
Because "the number" is "x," the number is 17.

Answer:
x = 35
Step-by-step explanation:
We can tell that these two angles are supplementary—that means that they add up to 180˚.
So, subtracting 75 from 180, we get 105. That's the value of angle 3x. Now, just divide 105 by 3. That's 35.
By that logic, x = 35.

Sylvain spent a total of 18 hours on English and math homework over the last 3 weeks. He spent twice as much time on English than on math. Let x represent the number of hours spent on English and y represent the number of hours spent on math.
x + y = 18. x = 2 y.
What is the solution of the system of equations?
(12, 6)
(6, 12)
(9, 9)
(15, 3)
Answer:
12, 6
Step-by-step explanation:
we have two equations
x + y = 18 .... . (i)
and x = 2y .... .(ii)
substituting the value of x from eq. (ii) in eq. (i)
2y + y = 18
3y = 18
y = 6
putting this value if y in equation (ii) to get x
x = 2 × 6
= 12
therefore,
(12, 6) is the solution to the system of equations

Aight let's answer this step by step
What you need to know is if two values are equal either one will be similar to the other it's only the format that's different if you calculate each of the fractions you'll see each pair is equal except for the last option
Where if calculated
8/3=2.67 but
5/4.8=1.04
Therefore values aren't equal to each other
Help pls, can you solve for x?
Answer:
X=1.5, but I may be incorrect, hope this helps!
Step-by-step explanation:
FACTS I KNOW:
X has to be less than 2 but greater than 1
Angle B and D are 90 degrees
The complete bottom side is equal to 10
All triangle angles add up to 180 degrees
All angles in rectangles and squares are 90 degrees
All rectangles have 2 sets of 2 of the same sides.
If you take a piece of the top right you could make a rectangle
It would take about .5 of the 2
Therefore X=1.5 approximately, but I may be wrong.

Answer:
A) ≈ 6.93
B) ≈ 0.02
Step-by-step explanation:
A)
Formula : a² + b² = c²
2.4² + 6.5² = c²
5.76 + 42.25 = c²
c = √48.01
c ≈ 6.93
B)
Formula = c² - a² = b²
1/3² - 1/4² = b²
1/9 - 1/16 = b²
b = √7/144

Answer:
A)
Data:
P = 6.5 cm
B = 2.4 cm
H = ?
▪ [tex]H^{2} = P^{2} + B^{2}[/tex]
=> [tex]H^{2} = 6.5^{2} cm+ 2.4^{2}[/tex] cm
=> [tex]H^{2}[/tex] = 48.01 cm
=> H = [tex]\sqrt{48.01}[/tex] cm

Answer:
B) 28 inches.
Step-by-step explanation:
After 1/8 of a ribbon is thrown away, the remaining part is cut into two pieces whose lengths are in the ratio 4 : 5.
And we want to find the length of the shorter ribbon from the two remaining pieces.
We are given that 9 inches of the original ribbon was thrown away. Since this is 1/8 of the total length, we can write that:
[tex]\displaystyle \frac{1}{8}L=9[/tex]
Where L represents the total length of the ribbon.
Solve for the total length:
[tex]\displaystyle L=72\text{ inches}[/tex]
So, the original length of the ribbon was 72 inches.
Since we threw away 9 inches of it, we now only have 63 inches.
This is then cut into two pieces in a ratio of 4 : 5. Let x represent the constant. Thus:
[tex](4x)+(5x)=63[/tex]
Solve for x:
[tex]9x=63\Rightarrow x=7[/tex]
Hence, the two remaining ribbons measure 28 inches and 35 inches.
Therefore, our answer is B.

If 3x - 6y = 8, then x - 2y =
Answer:
8/3 or 2.6666
Step-by-step explanation:
You have divided the first equation by 3 -- all except the 8. So you must divide the 8 by 3 giving you 8/3 which is 2 2/3 or 2.66666
Answer (x - 2y) = 8/3
x-2y=8/3 is the required expression.
3x - 6y = 8
x - 2y =?
What is equation?
equation is the interlink between variable and represented as y=mx+c
3x - 6y = 8
taking 3 common from above equation.
3(x-2y) = 8
x-2y = 8/3
Thus the required expression is x-2y = 8/3

Eva conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 3 hours. What does this range say about the data?
A. The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
B. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
C. All the students surveyed spend exactly 3 hours surfing the Internet.
D. All the students surveyed spend an average of 3 hours surfing the Internet.
Answer
The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.
Explanation
The meaning of range is the difference between the largest and smallest numbers in a set.
In this case, it's possible that one of the students spends no time surfing the internet, and another student spends 3 hours. The range of the data would be 3. It's also possible that some students spend 20 hours surfing the internet, and other students spends 23 hours surfing the internet (although, that's obviously unreasonable).
Answer:
B. The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 3 hours.

You are writing a science research paper for your Chemistry class. You can type four pages per hour and you have already typed two pages. Write a function where t represents the number of hours and W(t) is the total pages written.
Answer: W(t) = 4t + 2
Step-by-step explanation:
y = ax + b
Because you have already typed two pages, the y-intercept(b) will be 2
The slope(a) is the number of pages typed per hour, which is 4.
So if you put it together:
W(t) = 4t + 2
From an 18-pound cut of meat, Mr. Rand cuts off steaks weighting 1 pound 15 ounces, 3 1/8 pounds, and 4 1/2 pounds. He divides up the rest into 9-ounces patties and sells them at 3 for $3.12. How much money does he receive for the patties?
Answer is in the picture
The amount of money received by him will be $15.60.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division
The amount will be calculated as follows:-
The cut off amount = 18 - ( 1(15/16) -3(1/8)-4(1/2) = 8(7/16)
Now 16 ounces make a pound so divide by 16 we get:-
(135/16) ÷ ( 9 / 16 ) = ( 135/16 ) x ( 16 / 9 ) = 15
Dividing 15 by 3 we get 5 packs of 3 patties for $3.12
So amount = 3.12 x 5 = $15.60
Therefore the amount of money received by him will be $15.60.
