Answer: 6.9
Step-by-step explanation: Find the number in the tenth place 8
and look one place to the right for the rounding digit 7. Round up if this number is greater than or equal to 5 and round down if it is less than 5.
6.9
Answer:
6 green marbles should be added.
Step-by-step explanation:
If the probability of drawing a blue marble from 18 marbles is 2/3 then there are 12 blue marbles because 18 times 2/3 is 12. This means that to reduce this probability to 1/2 you need to add 6 more marbles to the total amount to get it to 24. Now the probability of getting a blue marble is 12/24 which is 1/2.
Answer:
The number of small boxes is 9 and the number of large boxes is 3
Step-by-step explanation:
Let x be the number of large boxes.
The camp bought 3 times as many small boxes as large boxes, then the number of small boxes is 3x.
Each small box has 6 granola bars, then there are 
granola bars in 3x small boxes.
Each large box has 12 granola bars, then there are 
granola bars in x large boxes.
All boxes had 90 granola bars, so
Answer:
24
Step-by-step explanation:
Let Noah = x. I will write the equation in order of appearance with Noah first.
x + 3x + (3x + 5) + (3x + 12) + (x - 4) + 2(x-4) = 317
Distribute where needed and remove parentheses
x + 3x + 3x + 5 + 3x + 12 + x - 4 + 2x - 8 = 317
Collect like terms
13x + 5 = 317
Move the constant to the right of the equal sign and do the math
13x = 312
Divide both sides by 13
Noah sold 24 cookies
Y=mx+b
slope= <u>rise
</u> run
<u />If its already graphed then you find where the line meets the y- line ( thats the b in the equation) from there you go up or down on the y- line to the point where the line next meets directly over another vertical line on the grid, the number of times you moved up or down is the "rise" in the equation for slope. After finding rise your move left or right from that point on the y-line until you meet the point where the line is and that will be the run. That fraction or number once you simplify the equation is you slope. Hope that helps.
