If you have to change each to a decimal or fraction then
32% = 0.32 or 32/100, 6% = 0.06 or 6/100, 93% = 0.93 or 93/100, 150%= 1.50 or 150/100,
Lets name adult price as X and child price as Y
then
1X+3Y=27 (1)
2X+5Y=48 (2)
From (1) we see that X=27-3Y
Lets replace X in (2) with this formula
2(27-3Y)+5Y=48 or 54-6Y+5Y=48 and 54-Y=48 and Y=54-48 so Y=6
From (1) X=27-3*6; X=27-18; X=9
Adult = 9<span>€
Child = 6</span><span>€</span>
Answer:
the solution is (2, -2)
Step-by-step explanation:
We'll solve this system by substitution. Set y = x - 4 = to y = 4x - 10. The result, which no longer features y, is x - 4 = 4x - 10.
First, subtract x from both sides. We get -4 = 3x - 10, or 6 = 3x. Then x = 2.
Substituting 2 for x in y = x - 4, we get y = 2 - 4, or y = -2.
Then the solution is (2, -2).
Answer:
-i
Step-by-step explanation:
20i/10 - 12i/4 =
2i - 3i =
-i
