I believe it is 56 because 7•8 is 56 and 1•56 is 56
Answer:
X = 18
Y = 18
Step-by-step explanation:
first make two equation like
x + y = 36
1180x + 125y = 23490
from equation one we have
y = 36- x
put in second equation
1180x + 125 (36-x) = 23490
1180x + 4500-125x = 23490
1055x = 23490-4500
x = 18990/1055
x = 18
put this x value in equation 1 to find y value
18+ y = 36
y = 36-18
y = 18
Answer:
C
Step-by-step explanation:
y = (x-1) (x+4)
when y=0
x=1 and x= -4
so select C
Answer:
B: The hypothesis is revised and another experiment is conducted.
Step-by-step explanation:
If several different experiments all reveal that the hypothesis has not been confirmed, a revision of the hypothesis is in order. Perhaps it was the hypothesis all along that needed amendment.
