Answer: she needs a 9 from the fifth judge
Step-by-step explanation: so you have 5 judges and to get a perfect score you need 8. when you multiply the amount of judges by the score of 8 you get 40 witch is 100%, and when you add 6+8+9+8 you get 31 so there is 9 missing to get 40 so the answer is 9.
To work out the average, you add all the terms and divide that by the number of terms there are.
64 + 63 = 127
127 ÷ 2 = 63.5
The answer is 63.5.
However, because these are only two consecutive integers, you just add 0.5 to find the average. e.g: average of 2 and 3 = 2.5, average of 3 + 4 = 3.5, average of 6 + 7 = 6.5 etc... Remember, this only works if there are only two integers and they are consecutive.
Math homework, im excillent at math but dm me
[email protected] and ill sent you the A
X is t shirt is $8
Y is sweatshirt $11
2x+2y=38
3x+1y=35
We will be using the elimination process so you want even them out same value
2x+2y=38
-6x-2y=-70 ( want get rid of the y-value by increasing to other by when both add or subtract it will equal 0)
-4x=-32
Divide both -4
X=8 So 8 dollars a t-shirt so now will fill x with 8
2(8)+2y=38
16+2y=38
-16
2y=22
Divid by 2
Y = 11 so a sweatshirt is 11 dollars
You can check by fill each by the variable
what are you asking im confused
