234 = a + s s = students a = adults
2a = s
after you get the equations you solve. plug 2a into the above equation.
so u get
234 = a + 2a
234=3a then divide 3 from each side
78 = a
so 78 adult tickets were sold
Answer:
nominal rate of interest is 31.7 %
Step-by-step explanation:
given data
payment = $1000
time = 2 year
rate = 4%
CPI = 100
CPI final yer = 127.7
to find out
nominal rate of interest
solution
we know nominal rate of interest formula that is
nominal rate of interest = real interest rate + inflation rate .........1
so here inflation rate is express as
inflation rate = ( CPI final year - CPI ) / CPI × 100 ...........2
put here value
inflation rate = ( 127.7 - 100 ) / 100 × 100
inflation rate is 27.7 %
so from equation 1
nominal rate of interest = real interest rate + inflation rate
nominal rate of interest = 4% + 27.7%
nominal rate of interest is 31.7 %
f = 2
Simplify both sides of the equation <span><span>1.25f</span>+2</span>=<span><span>−<span>2.75f</span></span>+<span>10
Add 2.75 to each side </span></span><span><span>4f</span>+2</span>=<span>10
Subtract 2 from both sides </span><span>4f</span>=<span>8
Divide each side by 4 </span>f=<span>2</span>

Answer:
16
Step-by-step explanation:
let the number be x , then
x = 15 ( multiply both sides by 4 to clear the fraction )
3x = 60 ( divide both sides by 3 )
x = 20 , then
× 20 = 4 × 4 = 16
