Answer:
£50
Step-by-step explanation:
£1 = $1.54
£x = $77
Cross multiply.
1.54x = 77
x = 77/1.54
x = 50
You would get £50 for $77.
Answer:
d) the numbers are 9 and 12
Step-by-step explanation:
set each factor equal to 108:
m-12=108
m = 120
*************
m-9=108
m=117
*************
120 and 117 are 3 units apart
****************
9 x 12 = 108
the set of solutions of the equation |f(x)|=a
is always equivalent to sum of sets of solutions of equations:
f(x)=a
and
f(x)=-a
therefore correct answer is the first and the second equation
