3n + (4n - 2) = 15
is how this equation would be displayed.
Now let's solve for x.
We can distribute a 1 to each term in the parentheses (which doesn't do much) to allow us to combine like terms.
3n + 4n - 2 = 15
Combine like terms.
7n - 2 = 15
Add 2 to both sides.
7n = 17
Divide both sides by 7.
n = 17/7
Answer:
Step-by-step explanation:
Part A : when comparing graphs : A system of equations will have no solutions (on a graph) when your lines never cross each other. They never cross each other because your lines are parallel.
Part B : by comparing each algebraic equation : A system of equations will have no solution if your lines are parallel. Parallel lines will have the same slope but different y intercepts. Example :
2x - y = 2
4x - 2y = 8
put both equations in slope intercept form
y = 2x - 2
y = 2x - 4
they both have the same slope of 2.....and the y intercepts are different....meaning they are parallel lines and have no solutions
Answer:
the ounces of dough did you buy is 78
Step-by-step explanation:
The number of dough ounces that should be buy is given below:
Given that
There is a requirement of 6 dough ounces and 4 sauce ounces
So for each person it would be
= 4 + 6
= 10
Now the total ounces bought is 130
So, the number of people used
= 130 ÷ 10 ounces
= 13 people
Now let us assume the number of dough ounces be x
Now if there is 6 dough ounces and there are 13 people
So, the total dough ounces purchased is
x = 6 × 13
= 78
Hence, the ounces of dough did you buy is 78
Y= 3.94x Y is representing the total amount of money owed and x represents how many pounds of blueberries.
