<span> x=8+4t
y=-1+8t
t = 0 x = 8 y = -1
</span>
t = 1 x = 12 y = 7
t = 2 x = 16 y = 15
7/8times16/1 gives 112/8, which is 14.
you multiply both numerators over both denominators.
Answer:
12
Step-by-step explanation:
3 times 4 is 12
Caitlin has 27 $5 bills and 54 $10 bills.
Step-by-step explanation:
Given,
Worth of $5 and $10 bills = $675
Let,
Number of $5 bills = x
Number of $10 bills = y
According to given statement;
5x+10y=675 Eqn 1
She has twice as many $10 bills as $5 bills.
y=2x Eqn 2
Putting value of y from Eqn 2 in Eqn 1

Dividing both sides by 25

Putting x=27 in Eqn 2

Caitlin has 27 $5 bills and 54 $10 bills.
