Answer:
If solving for y: y = 8 - 2x
If solving for x: x =
Step-by-step explanation:
<u>To solve for y:</u>
Factor out the common term, which in this case is 3.
3(2x + y) = 24
Divide both sides by 3.
2x + y =
Simplify to 8.
2x + y = 8
Subtract 2x from both sides.
y = 8 - 2x
<u>To solve for x: </u>
Factor out the common term, which in this case is 3.
3(2x + y) = 24
Divide both sides by 3.
2x + y =
Simplify to 8.
2x + y = 8
Subtract y from both sides.
2x = 8 − y
Divide both sides by 2.
x =

First move the -8 on the left to the right. this makes the inequality become 8x≤-64. Then you want to isolate the x by dividing 8x by 8, and make sure to do the same to -64. This makes it become x<span>≤-8, which is your final answer! Hope this helped :)</span>
Answer: 94.5
Step-by-step explanation:
If average of 9 students is 94, their total will be 94x 9 = 846
If the 10th student scores 99, the new total is 846 + 99 = 945
So, the new average will be
945/10 = 94.5
Answer:
9.) I 5/14 * 4/13 10.) H 45
Step-by-step explanation:
For 9.) the probability the first time to get a red marble is 5/14 because there are 5 red marbles and 14 total marbles. The probability the second time she picks, if a green one was chosen, one is 4/13 because one green marble needs to be missing and because one marble is missing 14-1=13 so there are 13 total marbles. You would multiply the two probability (5/14 and 4/13) to find the probability of drawing two green marbles in a row
For 10.) I found that 2/5= .4 and 5/8= .625 so I multiplied both fractions by 200
.4 * 200= 80
.625 * 200= 125
These are the numbers of games both people won
Subtract the two and you get 125-80= 45 which is how many more games Tyrell would win.
