2/54 is the answer I think
Answer:
(59,35)
Step-by-step explanation:
We want to solve the system
-x+2y=11
3x-5y=2
We multiply the top equation by 3 to get:
-3x+6y=33
3x-5y=2
Add both equations to eliminate x
y=35
Put y=35 into top original equation
-x+2(35)=11
This means that
-x+70=11
-x=11-70
-x=-59
x=59
Answer:
EC = 28'
Step-by-step explanation:
Since ∆KAR ~ ∆ENC, therefore, their corresponding side lengths will be proportional to each other.
By implication, we have:
EN/KA = EC/KR
EN = 96'
KA = 24'
EC = ?
KR = 7'
Thus:
96/24 = EC/7
Cross multiply
EC*24 = 7*96
EC*24 = 672
Divide both sides by 24
EC = 672/24
EC = 28'
