Find four consecutive integers such that 8 times the sum of the first and the third is 40 greater than 10 times the fourth

tatuchka [14]

All four consecutive integers will be 9, 10, 11, and 12 and can be found out by high common sense.

<h3>What is the pattern?</h3>

A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.

For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.

Given that,

8 times the sum of the first and the third = 8( 1st + 3rd)

40 greater than 10 times the fourth = 40 + 10(4th)

So,

8( 1st + 3rd) = 40 + 10(4th)

Now if we look right and side then it will come out as any number with the unit placed as 0.

So it means on the left side also the unit place must be 0.

By thinking of 1st + 3rd = 10 /20 because at 45 it will be 40 which is not equal to the right-hand side.

Now by hit and trial method, we need to guess it 20 = 9 + 11

Then

8(9 + 11) = 40 + 10(12)

One equation can never give us three unknowns hence it will be the correct way.

Hence so the four consecutive integers will be 9, 10, 11, and 12.

Answer this question please and thank you

Molodets [167]

Answer:

$\frac{1}{729}$

Step-by-step explanation:

1) Use the division distribution property: (x/y)^a = x^a/y^a.

$\frac{1}{9^{3} }$

2) Simplify 9³ to 729.

$\frac{1}{729}$

Therefor the answer is 1/729 and in decimal form it would be 0.001372.

Which of the following is the contrapositive of the statement "If I travel, I will go to France"?

shtirl [24]

Contrapositive is basically the converse of the statement. For example, the contrapositive of the statement "If the color is blue, then the fence is blue" is "If the color is not blue, the fence is not blue". Our answer choice that is correct is choice A.
