7000000 times 12000000
84000000000000
Answer:

Step-by-step explanation:
According to the following pattern sequence (
), it is <u>Arithmetic Sequence</u>, because every negative number is subtracted by
. So, to find the <u>24th term</u>, you need to use the <u>Arithmetic Sequence Formula</u> and solve to find the 24th term:

: nth term in the sequence
: 1st term
: term position
: Common difference
-Apply to the formula:





-Solve:




Therefore, the 24th term is
.
Answer:
Step-by-step explanation:
Find x
- 8/10 = 5/(5 + x) Cross multiply
- 8*(5 + x) = 10*5 Combine on the right
- 8(5 + x) = 50 Remove the brackets on the left.
- 40 + 8x = 50 Subtract 40 from both sides.
- 40-40 +8x = 50-40 Combine
- 8x = 10 Divide by 8
- 8x/8 = 10/8 Divide
- x = 1.25
Find y
- 7/(7 + y) = 8/10 Cross multiply
- 8*(7 + y) = 10 * 7 Combine the right
- 8(7 + y) = 70 Remove the brackets.
- 56 + 8y = 70 Subtract 56 from both sides
- 56 - 56 + 8y = 70 - 56 Combine
- 8y = 14 Divide by 8
- y = 1.75
