Answer:

The three consecutive integers are 2,3,4

Step-by-step explanation:

Let the three consecutive integers be represented as x,x+1,x+2

As per the given condition, the sum of the first and twice the second integer is equal to the third integer plus 4.

Representing it in the form of an equation:

x + 2*(x+1) = (x+2) + 4

=> x + 2x + 2 = x+6

=> 3x + 2 = x + 6

=> (3x -x) = 6 - 2

=> 2x = 4

=> x = 4/2 = 2

So the three integers are 2,3,4

Verification: 2 + 2*3 = 8

4 + 4 = 8

So the requirement is satisfied by these integers.

If Valerie deposited 12,000 into an account threat earns 15% simple annual interest how much money will she have after 3 years

Ad libitum [116K]

Answer:

The amount which she will have into account after 3 years is 17,400 unit

Step-by-step explanation:

Given as :

The principal which is deposited into an account = 12,000 unit

The rate of interest simple annual = 15%

The Time period = 3 years

Let The amount which she have after 3 years = A unit

<u>From simple Interest method</u>

Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

Or , Simple Interest = $\frac{12,000\times 15\times 3}{100}$

Or, Simple Interest = $\frac{540,000}{100}$

∴ Simple Interest = 5,400 unit

Now,

Amount = Principal + Simple Interest

Or, A = 12,000 unit + 5,400 unit

∴ A = 17,400 unit

Hence The amount which she will have into account after 3 years is 17,400 unit . Answer

What is the X values such that y equals 15 - 3 X and Y equals 0 question

Oksana_A [137]

X=5. this is true because if y=0 and y=15-3x, then 15-3x=0. if x is 5, it would be 15-3(5)=0.
