One egg and 2 glass of juice cost $2.30.two egg and 1 juice cost $3.40. what does one egg plus one juice cost?

Simplify the question so it uses x's and y's or any two letters instead of egg/juice (not necessary)

egg = x

juice = y

x + 2y = 2.30

2x + y = 3.40

Make x the subject

x = 2.30 - 2y  

Add pervious step to 2x + y = 3.40 then solve for y

2(2.30 - 2y) + y = 3.40

4.60 - 4y + y = 3.40

4.60 - 3y = 3.40

-3y = -1.20

3y = 1.20

y = 0.40

Now solve for x

x + 2y = 2.30

x + 2(0.40) = 2.30

x + 0.80 = 2.30

x = 1.50

One egg costs $1.50

One juice costs $0.40

Therefore, one egg plus one juice costs $1.90

Add previous step to 2x + y = 3.40 then solve for y

Now solve for x

x + 2y = 2.30

x + 2(0.40) = 2.30

x + 0.80 = 2.30

x = 1.50

One egg costs $1.50

One juice costs $0.40

Therefore, one egg plus one juice costs $1.90

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
