27j-6=14j+7
Subtract 14j from both sides
27j-6-14j=14j+7-14j
13j-6=7
Add 6 to both sides
13j-6+6=7+6
13j=13
Divide both sides by 13
13j/13=13/13
j=1
I hope that's help !
Answer:
C
Step-by-step explanation:
3/4^2 is just 3/4 x 3/4 which is 9/16
The mean of a set of numbers is the sum divided by the number of terms.So, 20+24+12+44+68 / 5
mean = 33.6
Cosα=adjacent side divided by the hypotenuse
cosA=24/26=12/13
cosB=10/26=5/13
