I'm not sure if this is what ur lookin for but this is supposed to be the answer
<span>According to the figure, the two lenghts AE and EC are congruents, and so are AE and ED.Besides the two lines AB and DC are parallels, consequently angle A and C are congruent (interior Alternate angles). All this statements tell that triangle ABE and Triangle DEC congruent by the Side Angle Side Postulate, so the true answer is B.) Triangle AEB and Triangle CED</span>
Answer:
18%
Step-by-step explanation:
Since the original price is $78 then this is the original 100% of the price. The new price will be marked up x percent and be $92. To find the new price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(78) = 92(100)
78x = 9200
x= 117.9 = 118%
This is 18% more or over the original price.
Step-by-step explanation:
-9x-4y=1....eq1
3x+3y=3.....eq2
multiply eq2 by 3
to get
9x+9y=9....eq3
add eq1 and 3
0+5y=10
5y=10
divide both sides by 5
y=2
substitute y=2 in to eq1
-9x-4(2)=1
-9x-8=1
grouping of like terms
-9x=1+8
-9x=9
divide both sides by -9
x= -1
now the answer is
x= -1, y=2
