You would take half of the x term...and square it
so half of 8 is 4....4^2 = 16
u would add 16 to each side
let the unknown answer be equal to f
.-2.1 - f = -3/2
-f = -3/2 + 2.1
-f = 0.6
f = -0.6
8.46...hundredth. 8.5....tenths
Answer:
First diagonal: 7.874
Second diagonal: 8.3666
Step-by-step explanation:
We use the Pythagorean Theorem to find these.
First diagonal = 5²+6²=c²
25+36=c²
61=c²
√61=c
c=7.874
Then we use that to find the second diagonal.
7.874²+3²=c²
61+9=c²
70=c²
√70=c
c=8.3666
Answer:
4) 23.3
5.1) 22.2
5.2) 0.045
Step-by-step explanation:
4) minutes per worksheet = minutes/ worksheets
2 hours and 20 minutes = 120 minutes and 20 minutes = 140 minutes.
6 worksheets in total so:
140/6= 23.333.. (23.3 bar)
5) same thing
total km per total liter = total km divided by total liter= km/l
200/9= 22.22.. ( 22.2 bar)
5.2) same thing but opposite
total liter of total km= l/km = 9/200 = 0.045
