Given the set of equations:
2x + y = 10
y = 3x
Let's solve for x and y.
Here, let's use substitution method.
Substitute 3x for y in equation 1:
2x + y = 10
2x + 3x = 10
5x = 10
Divide both sides by 5:

In equation 2, substitute 2 for x to find y.
y = 3x
y = 3(2)
y = 6
Therefore, we have:
x = 2 and y = 6
ANSWER:
x = 2, y = 6
Answer:
I'm pretty sure "x" is 3 because
Step-by-step explanation:
3 x 2 is 6 + 1 is 7
Answer:
Nolan took <u>100</u> seconds.
Step-by-step explanation:
Given:
Kong took 15%, percent fewer seconds than Nolan took to complete his multiplication timed test.
Kong took 85 seconds.
Now, to find the number of seconds Nolan take to complete the test.
Let the number of seconds Nolan take be 
Kong took = 85 seconds.
As, given Kong took 15%, percent fewer seconds than Nolan took.
Now, to get the number of seconds Nolan took:




<em>Dividing both sides by 0.85 we get:</em>

Therefore, Nolan took 100 seconds.
Y = cos x
After flipping a cross the x-axis
∴ y = - cos x
<span>After shifting vertically up by 2 units
∴ y = - cos x +2
the correct answer is option C</span>
<span>C.y = -cos x + 2
