what is the value of x in this equation
3(2x + 8) =0?
a.-8
b.-4
c.4
d.8
what is the value of A in this equation 4a + 3(a + 1) = 24
a.2
b.3
c.7
d.21

Answers

The the first one the answer should be -4

For the second one the answer should be 3

Answer: Simplifying

4a + 3(a + 1) = 24

Reorder the terms:

4a + 3(1 + a) = 24

4a + (1 * 3 + a * 3) = 24

4a + (3 + 3a) = 24

Reorder the terms:

3 + 4a + 3a = 24

Combine like terms: 4a + 3a = 7a

3 + 7a = 24

Solving

3 + 7a = 24

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 7a = 24 + -3

Combine like terms: 3 + -3 = 0

0 + 7a = 24 + -3

7a = 24 + -3

Combine like terms: 24 + -3 = 21

7a = 21

Divide each side by '7'.

a = 3

Simplifying

a = 3

The sum of two consecutive integers is 81. Determine the lesser of the two numbers.

Answers

Given that,

the two numbers are consecutive

The two numbers are

x and x + 1

Sum of the numbers = 81

x + (x + 1) = 81

x + x + 1 = 81

2x = 81 - 1

2x = 80

x = 80/2

x = 40

Therefore, the two numbers are x = 40 and x + 1 = 41

how many natural numbers N have the property among 1,2,..........,N exactly 30% are divisible by 3?
A. 0
B. 2
C. 6
D. infinite

Answers

Answer:

The answer is B. 2.

Step-by-step explanation:

We know that for N = 1 and N = 2, none of them are divisible by 3.

For N = 3, 33.33% are divisible by 3.  For N = 4, 25% (which is already less than 30%), so N = 5 would also be less.

At N = 6, we're back up to 33.33%.  N = 7 is already less than 30%.

At N = 9, you guessed it, 33.33%.  N = 10 is 30% (3, 6, and 9).  So we have one case.

Moving along, at N = 18, 33.33%.  N = 20 is again 30% (3, 6, 9, 12, 15, and 18).  Two cases now.

Finally, at N = 21, again 33.33%.  N = 22 and N = 23 are both greater than 30%.  As we continue this, for any N after 20, we will always be greater than 30%.
