Answer:
-3x^2y^2(2x^2y^3 + 5x - 3y)
and 5x+3y=12in substitution form
Answer:
x = 4.5 and y = -3.5
Step-by-step explanation:
To find the solution to this system of equations using the substitution method, you must solve for either the x or y variable and then substitute into the other equation.
x = (y + 8)
5x + 3y = 12
We will use the first equation to solve for x. The x has to be isolated on one side. Since the first equation already has x on the one side, we can plug it into the other equation.
5(y+8) + 3y = 12
Distribute and solve:
5y + 40 + 3y = 12
8y + 40 = 12
8y = 12-40
8y = -28
y = -3.5
Now we have the y variable, we can plug that back into the first equation to find x.
x = (-3.5) + 8
x= 4.5
Your answer will be x = 4.5 and y = -3.5
To solve this problem, you add all the numbers together and divide by the total amount of things. In this case, there are six scores, 210, 195, 213, 201, 226, and 155. You would add all of these things together, and then divide by six. All of these things added together equals 1,200. This divided by 6 is 200. David's average score would be a. 200. Hope this helps!
Answer:
'There are 7 rocks in 4 boxes, How many rocks are there in total.'
Step-by-step explanation:
We are given to form a word problem having solution which has 4 as a factor.
Now, if we take the following statement,
'There are 7 rocks in 4 boxes, How many rocks are there in total.'
Its solution is given by,
As there are 4 boxes in total and each box has 7 rocks.
Thus, total number of rocks will be 4 × 7 = 28.
We can see that 4 is a factor of 28.
Hence, the word problem could be 'There are 7 rocks in 4 boxes, How many rocks are there in total.'
Tanner = 40% * Reggie;
Reggie = Tanner : 40%;
Reggie = 360 : 40/100 = 360 * 100/40 = 900 bottles
