If a + 4b = 33 and 6a + 3b = 51, what is the value of a + b?
(I got 5 but it was wrong)
Answer:
12
Step-by-step explanation:
Since the problem asks for $a+b$, we look for a way to isolate $a+b$ from the given equations.
Notice that $a + 6a = 7a$ and $4b + 3b = 7b$. This gives us the key to isolating $a + b$. We simply add the two equations together:\begin{align*}
7a + 7b &= 84 \\
7(a + b) &= 84 \\
a + b &= \frac{84}{7} \\
a + b &= \boxed{12}
\end{align*}

Conclusion: This expression is a polynomial.
2. [tex]20x^2[/tex]
This expression can be rewritten as [tex]\( 20x^2 \)[/tex].
It consists of variable [tex]\( x \)[/tex], coefficient ([tex]20[/tex]), and exponent ([tex]2[/tex]).
It involves multiplication and addition (implied by the term).
Conclusion: This expression is a polynomial.
3. [tex]20x^2+ y[/tex]
This expression consists of two terms: [tex]\( 20x^2 \)[/tex] and [tex]\( y \)[/tex]
[tex]\( 20x^2 \)[/tex] is a polynomial (as identified above).
[tex]\( y \)[/tex] is also a polynomial (since it can be seen as [tex]\( 1y^1 \)[/tex], where the coefficient is [tex]1[/tex] and the exponent is [tex]1[/tex]).
The expression involves addition and multiplication.

graph the line whose x-intercept is -8 and whose y-intercept is 9
The graph of the line whose y intercept is 8 and whose x intercept is 9 is given below.
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
Given:
An intercept form of the standard line is,
x/a + y/b = 1, where a and b are x-intercept and y-intercept form of the line.
So, the equation is,
x/-8 + y/9 = 1
And the graph is given in the attached image.
Therefore, the graph is given.

The hardcover version of a book weighs 7 ounces while its paperback version weighs 5 ounces. Forty-five copies of the book weigh a total of 249 ounces. Which value could replace x in the table?
Solving the system of linear equations, we found that there are 12 hardcover books and 33 paperback books, making the value that could replace 'x' is 12.
The question involves solving a system of linear equations to find the number of hardcover and paperback versions of a book that together weigh 249 ounces. Since the hardcover version weighs 7 ounces and the paperback weighs 5 ounces, we can create two equations based on the given information. If we let x represent the number of hardcover books and y represent the number of paperback books, the equations would be:
x + y = 45 (since there are 45 copies in total)
7x + 5y = 249 (since the total weight is 249 ounces)
Solving this system, we can multiply the first equation by 5, which gives us 5x + 5y = 225, and subtract this from the second equation to find the value of x. This yields 2x = 24, so x = 12. Therefore, there are 12 hardcover books and the rest are paperbacks. To find the number of paperbacks, we substitute x back into the first equation and get 12 + y = 45, which means y = 33. Hence, the number that could replace x in the table is 12.

i.e. the points are closely related to the line.
Also, the other properties of a trend line are--The magnitude of the negative and positive residual values must be same.
( i.e. Not all point could lie above the line and not all points could lie below the line )
( In graph A most of the points lie below the line.
Hence, Graph A is not the correct answer.
In graph most of the points lie above the line.
Hence, Graph C could not be the best model.
In graph D most of the points lie above the line and hence it could not be the best model)
whereas in Graph B there are equal number of points above and below the line.

Rick shared his bag of grapes with his friends. He gave 2/10 of the bag to Melissa and 4/10 of the bag to Ryan. What fraction of the bag of grapes does Rick have left?
After giving away 2/10 of his grapes to Melissa and 4/10 to Ryan, Rick has 4/10 of his bag of grapes left.
Explanation:Rick gave away part of his bag of grapes to his friends: 2/10 to Melissa and 4/10 to Ryan. To find out what fraction of the bag he has left, we need to add together the fractions that he gave away and then subtract this from the whole bag, which is represented by the fraction 1 (or 10/10).
Rick gave away:
Melissa: 2/10
Ryan: 4/10
Total given away: 2/10 + 4/10 = 6/10
Fraction of the bag Rick has left:
1 (or 10/10) - 6/10 = 4/10
Therefore, Rick has 4/10 of the bag of grapes left after sharing with his friends.
To find out how much of the bag of grapes Rick has left, we need to subtract the fractions that he gave to Melissa and Ryan from 1. Rick has 2/5 of the bag of grapes left.
Explanation:To find out how much of the bag of grapes Rick has left, we need to subtract the fractions that he gave to Melissa and Ryan from 1.
Given that Rick gave 2/10 of the bag to Melissa and 4/10 of the bag to Ryan, we can calculate the fraction of the bag he has left by subtracting these two fractions from 1:
1 - 2/10 - 4/10 = 1 - 6/10 = 4/10 = 2/5
Therefore, Rick has 2/5 of the bag of grapes left.

jerry was playing a video game. it took him 10 lives to beat the 2nd world, 5 times as many as it took him to beat the 1st world. how many lives did he use to the 1st world?
Final answer:
Jerry used 2 lives to beat the 1st world, determined by dividing the 10 lives used for the 2nd world by 5.
Explanation:
Jerry used 10 lives to beat the 2nd world and it took him 5 times as many lives as it did to beat the 1st world. To find out how many lives it took him to beat the 1st world, we need to divide the number of lives used for the 2nd world by 5.
Let x represent the number of lives Jerry used to beat the 1st world. The equation based on the given information is:
5 * x = 10
Now, we solve for x:
x = 10 / 5
x = 2 lives
Therefore, Jerry used 2 lives to beat the 1st world.
