Answer:
honesty you cant realy use a calculator because you need to meadian mode and range them first
Step-by-step explanation:
The final score is 38. I got that answer by taking the total amount and subtracting the total score from the other game.
The solution for the problem is as follows:
((12x + 15y)/228) = 13
x + y =228
x = kentucky bluegrass
<span>y = chewings fescue
</span>
By systems of linear equations, the answers would be:
x = 152
y = 76
Therefore, there should be 152 pounds of Kentucky bluegrass to be used and 76 pounds of chewings fescue.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
6j + 1/3n = 134...multiply by 3....18j + n = 402
1/3j + n = 31....multiply by 3....j + 3n = 93
the multiplying by 3 is optional...I just did it because it is easier to work with equations when there are no fractions.
18j + n = 402....multiply by -3
j + 3n = 93
----------------
-54j - 3n = - 1206 (result of multiplying by -3)
j + 3n = 93
----------------add
-53j = - 1113
j = -1113/-53
j = 21
j + 3n = 93
21 + 3n = 93
3n = 93 - 21
3n = 72
n = 72/3
n = 24
so Jasons collection (j) consists of 21 books and Nathans collection (n) consists of 24 books
Answer is 9
Step by step explanation
As CB is radius CB=3, CA=3+7=10
X^2=(7+3)^2-3^2=100-9=81
X=9
