X + (7 + 14x) = 15x + 7
hope this helps
X= number of adult tickets
y=number of child tickets.
we can suggest this system of equations:
x+y=118 ⇒x=118-y
7.5x+3y=696
we can solve this system of equations by substitution method:
7.5(118-y)+3y=696
885-7.5y+3y=696
-4.5y=-189
y=-189/-4.5
y=42
x=118-y
x=118-42
x=76
Answer: the number of adult tickets sold was 76.
Answer:
Step-by-step explanation:
y > 2/3x - 1/5
y ≥ 3/2x + 1/5
y ≤ 2/3x + 1/5
y < 3/2x - 1/5
(Assume that the question want you to draw a graph)
Remember:
> or < is a dotted line
≥ or ≤ is a solid line
Answer:
sqrt(20)
Step-by-step explanation:
The two perpendicular side lengths are equal, so using Pythagoras theorem:
x = sqrt( sqrt(10)^2 + sqrt(10)^2 )
x = sqrt(10 + 10)
x = sqrt(20)
Answer:
R = 2 % per annum.
Step-by-step explanation:
SI = (P*T*R) /100
$1000 = ($10000 * 5 yrs *Rate) /100
