3x+ 4 = 20

First you SUBTRACT 4 from both sides . Since these are inequalities we do reverse PEMDAS (Parentheses , Exponents , Multiply , Divide , Add ,Subtract). Then you will have an equivalent equation of

3x=16

Now we have to isolate X . So we divide 3 by both sides . Which will get 5.3333...

Therefore , The answer will be

Answer:

Subtract 4 ,

Subtraction property of equality

Step-by-step explanation:

When we solve a one variable equation then we isolate the variable in the left side,

Here, the given equation,

3x + 4 = 20,

For isolating x on left side first we need to remove constant term in the left side,

For this we need to subtract 4 from each side,

That is, 3x = 20 - 4

∵ Subtraction property of equality states that an equation does not change when we subtract same number from each side of the equation.

i.e. a = b ⇒ a - c = b - c, Where, a, b and c are real numbers.

The first term of an arithmetic sequence is -3 and the 15th term is 53. What is the common difference of the sequence?
Fittoniya [83]

Answer:

c = 4

Step-by-step explanation:

Let the common difference be c.  Then a(n) = -3 + c(n-1).  Since a(15) = 53, a(15) = -3 + (15-1)c = 53.  Therefore, -3 + 14c = 53, or 14c = 56; c = 4.

$6,000 dollars is invested in two different accounts earning 3% and 5% interest. at the end of one year, the two accounts earned
Anettt [7]

<u>Answer-</u>

<em>$2000</em><em> were invested at 5%</em>

<u>Solution-</u>

Let x amount of money was invested at 5% and (6000-x) amount was invested as 3%

We know that,

i=\dfrac{P\cdot r\cdot t}{100}

Putting the values,

i_1=\dfrac{P_1\cdot r_1\cdot t}{100}

i_1=\dfrac{x\cdot 5\cdot 1}{100}=\dfrac{5x}{100}

And

i_2=\dfrac{P_2\cdot r_2\cdot t}{100}

i_2=\dfrac{(6000-x)\cdot 3\cdot 1}{100}=\dfrac{3(6000-x)}{100}

According to the question,

\Rightarrow \dfrac{5x}{100}+\dfrac{3(6000-x)}{100}=220

\Rightarrow \dfrac{5x+3(6000-x)}{100}=220

\Rightarrow 5x+3(6000-x)=22000

\Rightarrow 5x+18000-3x=22000

\Rightarrow 5x-3x=22000-18000

\Rightarrow 2x=4000

\Rightarrow x=2000

Therefore, $2000 were invested at 5%

Answer:  -2x + 5y = 8

Step-by-step explanation:

Since the lines must be parallel, the slopes must be the same, so keep the coefficients of x and y

Substitute the values of x and y from the given coordinate  (6,4) to find the new constant, b, the y-intercept.

-2x + 5y = b

-2(6) + 5(4) = b

-12 + 20 = b

8 = b

Rewrite the original equation substituting the new b for the original -15

-2x + 5y = 8
