5 and 3 are two primary numbers for this question
100/66655*61364=<span>92.0621108694%</span>
Would assume cd means c*d
c*d is commutative because:
c*d = d*c
The result in multiplication is the same, irrespective of which comes first.
Ignore my answer for b, but all the rest are correct. a: about 2.94 c:12.24 cm
Answer:
x = -7/11, y = -14/11
Step-by-step explanation:
2x = y ------- (1)
7y = -7+3x -------- (2)
from (1)
2x = y
y = 2x ------- (3)
substitute (3) into (2)
7y = -7+3x
7(2x) = -7+3x
14x = -7+3x
14x-3x = -7
11x = -7
x = -7/11
substitute x = -7/11 into (3)
y = 2x
y = 2(-7/11)
y = -14/11
x = -7/11, y = -14/11
