Answer:
x=15 and y= -18
Step-by-step explanation:
Equation 1
Equation 2
From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.
Solving equation 1
Finding 'y' in terms of 'x' 
Equation 3
Putting above equation in equation 3 in 2
Putting value of 'x' in equation 3 to find the value of 'y'
For twice a number we can use the variable x
For four times a number we can use the variable c
4c - 2x + 15
I believe this is correct although I'm not 100% sure
Answer:
3.73 miles per hour
Step-by-step explanation:
12 Kilometers is 7.46 miles.
7.46/2 = 3.73 Miles per hour
<span>Are you in K12?? </span>Well Pltw has something to do with k12.....Project Lead The Way provides transformative learning experiences for K-12 students and teachers across the U.S. We create an engaging, hands-on classroom environment........ soooo yea...?
Sorry I don't know anything about that!
Hope this helps somehow, Ayitzdaisy!
We would need to look over the z table to find the area under the standard normal distribution curve to the left of z = 1.04. Then we'll subtract it from 1 to get the proportion of a normal distribution corresponding to z scores greater than 1.04.
By looking at the z table, we can see that the area to the left of z = 1.04 is 0.8508. So the proportion of a normal distribution to the right of z = 1.04 is 1 – 0.8508 = 0.1492.
The answer is 0.1492.
