Answer: The roses costed $9
Step-by-step explanation:
3 multiplied by 3 equals 9
1 multiplied by 6 equals 6
9+6=15
12 ^3 and 11^3 haven't got the same base so the rules of exponents do not apply.
Bases have to be the same:- for example 12^3 * 12*3 = 12 ^(3+3) = 12^6
Take 22 divided by 100. To get a decimal and then put that over 100 so the answer would be 22/100 I think I could be wrong
Answer:
Transitive property of equality is not a justification for the proof.
Step-by-step explanation:
We draw a right angle ΔACB. CD is perpendicular to AB.
Let AC = a , BC = b , AB = c and CD = h
Now in ΔABC and ΔACD
∠C = ∠D and ∠A = ∠A
from AA similarity postulate
ΔABC similar to ΔACD.
Hence,
=
= c × x ·····················(1)
Now in ΔABC and ΔCBD
∠C = ∠D and ∠B = ∠B
from AA similarity postulates
ΔABC similar to ΔCBD
Hence,
= c × y······················(2)
Add equation (1) and (2)
+ = cx + cy
+ = c(x+y)
+ = [because x+y=c]
Transitive property is not useful for this proof.
The negative x and postive x equals zero so x =-7
