To solve this, we simply need to break down the problem. Doing this will yield us the correct equation.
"8.46 less than"
This shows we are going to have something subtracted by 8.46.
-8.46
"the product of"
This shows we will have a multiplication problem.
*-8.46
"42 and x"
This shows the values that we will be multiplying
42*x-8.46
Now we can simplify
42x-8.46
Using the logic above, we can see that the expression to represent the phrase is 42x-8.46.
We found the factors and prime factorization of 70 and 77. The biggest common factor number is the GCF number. So the greatest common factor 70 and 77 is 7.
Answer:
31.1
Step-by-step explanation:
The number of blue roses will be 72. Then the number of red roses that she have at first is 84.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Mrs Fernandez has a total of 156 red and blue roses.
After selling the same number of red and blue roses.
She had 1/3 of the number of red roses and 2/9 of the number of blue roses left.
Let x be the number of red rose and y be the number of blue roses.
Then the equation will be
x + y = 156 ...1
2x/3 = 7y/9
6x = 7y ...2
By solving the equations 1 and 2, we have
x = 84 and y = 72
Then the number of red roses that she have at first is 84.

The answer is F. y=2.5x. This is because if you multiply each pound (x) from the table by 2.5, you will get the cost (y). Hope this helps!
