Answer: 10x - 5y = 40
Reason:
Why 5x - 10y = -12 is wrong (working):
5x - 10y = -12
-10y = -5x - 12
y = 0.5x + 1.2
(positive slope but not the correct y-intercept)
Why 10x - 5y = 40 is correct (working):
10x - 5y = 40
-5y = 40 - 10x
y = 2x - 8
(positive slope and correct y-intercept)
Why 5x + y = 50 is wrong (working):
5x + y = 50
y = -5x + 50
(negative slope and not the correct y-intercept)
Why x - 2y = 10 is wrong (working):
x - 2y = 10
-2y = -x + 10
y = 0.5x - 5
(positive slope but not the correct y-intercept)
Therefore, 10x - 5y = 40 is the answer
Answer:
Step-by-step explanation:
Given that:
Total Number of fourth downs = 10
Number of fourth downs converted to first downs = 6
Formula for probability of an event E can be observed as:
Here, Let E be the event of getting a fourth down converted to first down.
So, Number of favorable cases = 6
Total Number of cases = 10
Therefore, the required probability is:
Answer:
x = 4
Step-by-step explanation:
Hello!
We can solve for x by expanding the parentheses and isolating x.
<h3>Solve for x</h3>
- 3x - 2(2x - 5) = 2(x + 3)-8
- 3x - 4x + 10 = 2x + 6 - 8
- -x + 10 = 2x - 2
- 10 = 3x - 2
- 12 = 3x
- x = 4
The value of x is 4.
Answer:
just list the number of albums times the amount they cost plus songs and how much they cost and you got your equation
Step-by-step explanation:
Answer:
x = -10
Step-by-step explanation:
first, expand the left side of the equation (distributive property):
2x + 6 = x - 4
then, subtract x and 6 on both sides to put like terms together:
2x - x = -4 - 6
combine like terms:
x = -10
done! hope this helps!
