Let
x---------> amount of money saved by Mark
x---------> amount of money saved by Neil
we know that
x=y+258-------> equation 1
x/y=(7/4)-------> equation 2
substitute equation 1 in equation 2
(y+258) /y=7/4--------> 4*(y+258)=7*y------> 4y+1032=7y
7y-4y=1032--------> 3y=1032------> y=$344
x=344+258------>x=$602
the answer is
$602
Answer:
The odd in favor of drawing a red marble is 5:8
Step-by-step explanation:
Let’s calculate the probability of selecting a red marble
That would be;
number of red marbles/Total number of marbles
Total number of marbles = 2 + 5 + 6 = 13
So the probability of drawing a red marble is 5/13
The probability of not drawing a red marble = 1-5/13 = 8/13
So the odd in favor of drawing a red marble is 5:8
Answer: £450
Step-by-step explanation:
If they bought 2 tickets, they could get an extra ticket for free. As there are three of them, they would buy 2 tickets, get one for free and then buy another ticket to make it four.
In that case they would have only paid for 3 tickets.
The total cost of 3 tickets is:
= 600 * 3
= £1,800
The 4 of them would therefore have to pay:
= 1,800 / 4
= £450
X= 1.4
First, you combine like terms
-13x + 4x = -9x
Then you subtract 18x from each side so you can get -39 by itself
-9x -18x = -27x
Next you divide -27x by -27 and -39 by -27
-27/-27 = 1x
-39/-27 = 1.4
So X= 1.4
