Answer:
Step-by-step explanation:
an isosceles triangle is a triangle that has two sides of equal length
FU = 7 units
UN = 5 units
FN = 7 units
FU = FN
FU ≠ UN
FN ≠ UN
FUN is an isosceles triangle.
Answer:
3 I'm pretty sure it's 3333
With this information we can set up 2 equations:
x + y = 312 (# of tickets sold for adults + # of tickets sold to adults = 312)
12x + 5y = 2204 ( # of tickets sold for adults times $12 + # of tickets sold to adults times $5 = $2204)
Where x is how many tickets were sold to adults and y how many tickets were sold to children
Now we can solve this system of equations by substitution:
isolate y in the first equation to find its value and plug it in the second equation
x + y = 312
isolate y by subtracting x from both sides:
x - x + y = 312
y = 312 - x
Apply y = 312 - x to the second equation
12x + 5y = 2204
12x + 5( 312 - x) = 2204
12x + 1560 - 5x = 2204
7x + 1560 = 2204
Subtract 1560 from both sides to isolate x
7x + 1560 - 1560 = 2204 - 1560
7x = 644
Divide both sides by 7
7/7x = 644/7
x = 92
Now plugin 92 for x in the first equation to find the value of y
x + y = 312
92 + y = 312
subtract 92 from both sides
92 - 92 + y = 312 - 92
y = 220
x = 92, y = 220
92 tickets were sold to adults and 220 tickets were sold to children
Hope it helps :)

Answer: 500
Step-by-step explanation:
let we suppose x people went to the fair on Sunday.
now number of people attend the fair on monday=x-15%of x.
x-15x/100=100x-15x/100
85x/100
A/q
85x/100=425
85x=42500
x=42500/85
500
so, 500 people. attended the fair on sunday
