Answer:
20) the answer is -43
21) the answer is 25
22)the answer is -5
Step-by-step explanation:
20)
n=-7
p=-6
we have:
21) mp-(p-(m-n))
m= -1 n=-6 p=-10
-1*-10-(-10-(-1-(-6)))
10-(-10-(5))
10-(-15)
10+15=25
22)
m=1 n=5
1-
1- 2/2 -5
1-1-5 =-5
Answer:
50 square meter/hour
Step-by-step explanation:
using unitary method-
if 36mins(3/5 of 60mins)= 30 square meter
1min=30/36
60mins=(30/36)*60
in 60mins=50square meter or 50 square meter/hour
6:45pm. because from 4 to 12 would be 4 hours then subtract 5 more hours leaves you at 7:25 pm. now subtract 45 from that which leaves you at 6:45 pm.
Answer:
a/3b^2
Step-by-step explanation:
16a^2b^3c^6/48ab^5c^6
the c^6 cancel out, then simplify a^2 and a: 16a^2b^3/48ab^5 = 16ab^3/48b^5
Then divide 48 and 16 you get 3 16ab^3/48b^5 = ab^3/3b^5
And lastly, simplify b^3 and b^5 ab^3/3b^5 =
a/3b^2
