How do u solve 4p - 40 = 7(-2p + 2) ?
mr Goodwill [35]

Answer:

Simplifying

4p + -40 = 7(2p + 2)

Reorder the terms:

-40 + 4p = 7(2p + 2)

Reorder the terms:

-40 + 4p = 7(2 + 2p)

-40 + 4p = (2 * 7 + 2p * 7)

-40 + 4p = (14 + 14p)

Solving

-40 + 4p = 14 + 14p

Solving for variable 'p'.

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

Add '-14p' to each side of the equation.

-40 + 4p + -14p = 14 + 14p + -14p

Combine like terms: 4p + -14p = -10p

-40 + -10p = 14 + 14p + -14p

Combine like terms: 14p + -14p = 0

-40 + -10p = 14 + 0

-40 + -10p = 14

Add '40' to each side of the equation.

-40 + 40 + -10p = 14 + 40

Combine like terms: -40 + 40 = 0

0 + -10p = 14 + 40

-10p = 14 + 40

Combine like terms: 14 + 40 = 54

-10p = 54

Divide each side by '-10'.

p = -5.4

Simplifying

p = -5.4

5 more than the quotient of a number and 8 is 42
Zepler [3.9K]

Answer:

<u>The number is 296.</u>

Step-by-step explanation:

Let's call "x" to the number we are looking for.

Now, the problem states that "5 more than the quotient of a number and 8 is 42". This means that this number is being divided by 8, it's also being additioned 5 and the final result is 42. Therefore, the expression of this operations on this number is the following:

\frac{x}{8}+5=42. Let's solve the equation to find x.

1. Write the expression.

\frac{x}{8}+5=42

2. Substract 5 from both sides and simplify.

\frac{x}{8}+5-5=42-5\\\\\frac{x}{8}=37\\\\

3. Multiply 8 on both sides and simplify.

8*\frac{x}{8}=37*8\\\\x=296

<u>We have found our number, it's 296!</u>

Please help ASAP
GaryK [48]

Answer:

  • Any value of k

Step-by-step explanation:

The quadratic expression can be factored into two binomials if it has two real roots.

<u>Two real roots possible with non-negative discriminant:</u>

  • D ≥ 0

As D = b² - 4ac, we get the following inequality

  • k² - 4(3)(-8) ≥ 0
  • k² + 96 ≥ 0
  • k² ≥ - 96

This is true for any value of k

  • k ∈ (- ∞, + ∞)

What rate of interest compounded annually is required to double an investment<br> in 18 ​years?
andreev551 [17]

Answer:

r=3.93\%

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=18\ years\\ P=x\\A=2x\\ r=?\\n=1  

substitute in the formula above

2x=x(1+\frac{r}{1})^{1*18}  

2=(1+r})^{18}  

Elevated both sides to 1/18

2^{\frac{1}{18}} =1+r

r=2^{\frac{1}{18}} -1

r=0.0393

convert to percentage

Multiply by 100

r=3.93\%
