Answer:
0.90
Step-by-step explanation:
I entered it onto my calculator, but if you'd like an explanation as to how just ask.
7x - 4y = -28
3x +4y = -12
Using the elimination method because y is already eliminated
10x = -40
So x = -4
Then plug the -4 into the first equation....
7(-4) - 4y = -28
-28 - 4y = -28
-4y = 0
y = 0
I got: -4,0
Answer: $113.55
Step-by-step explanation:
add up the cost of the lesson, boots, board, and ticket
the lesson costs $33.80 and the ticket costs $25, these cover the whole day so no need to be multiplied. the boots cost $2 and the board costs $8.95 each hour, jim will need to pay the cost of both 5 times for 5 hours.
here is the equation to solve
33.80 + 5(8.95 + 2.00) + 25 =
33.80 + 5(10.95) + 25 =
33.80 + 54.75 + 25 =
33.80 + 79.75 = 113.55
the total cost is $113.55
Answer:
Step-by-step explanation:
6. 0 ,234,560 is divisible by 2.
7. 389,570 is divisible by 5.
8. 630,620 is divisible by 10.
9. 6+1+1+8+1=17 +(1)
611,811 is divisible by 3.
10. 5+2+5+4+3=19
multiple of 9 are 9,18,27,...
to make the sum 27 we have to add 8 to 19.
525,438 is divisible by 8.
