16y=6x+42
16/16y=6x/16+42/16
y= 3x/8 + 21/8
Answer:
Slope is 5/17.
Step-by-step explanation:
Subtract the y's and put on top of a fraction. Subtract the x's and put on the bottom of the fraction. Simplify. Be sure to start with the x and y that go together in front of the minus sign and end with the other x and y behind the minus sign.
7 - 2 put 5 on top.
11 - -6 is 17 (because 11 - -6 is the same as 11+6)
So you get 5/17 and it cannot be simplified so it is your answer.
A i think it could be wrong im only in middle school
Answer:
x = 3/2
Step-by-step explanation:
Given:
9 - 4x = 2x
Step 1: Addition property of equality
9 - 4x + 4x = 2x + 4x
9 = 6x
Step 2: Division property of equality:
9 = 6x
9/6 = 6x/6
9/6 = x
x = 9/6
= 3/2
x = 3/2
Check:
9 - 4x = 2x
9 - 4(3/2) = 2(3/2)
9 - 12/2 = 6/2
9 - 6 = 3
3 = 3
Answer:
38.46%
Step-by-step explanation:
There are 91 students and 35 of them received a score of 90 or above.
So, there are 35/91 students with an A grade.
The probability to pick a random student that would be the same proportion that those who got the right score, so 35 / 91 = 0.3846 or 38.46%
38.46% of chances to pick someone who got an A (90 score or above), and, the opposite, 61.54% of chances to pick someone who didn't get an A. That's a strong class!
