Answer:

  • -1

Step-by-step explanation:

<u>Let the number be x, and we have equation:</u>

  • 16x + 2 = -7x - 21
  • 16x + 7x = - 21 - 2
  • 23x = - 23
  • x = -1

The number is -1

Answer:

-1

Step-by-step explanation:

"a number" = x

-- <u>"Two more</u> than <u>16 times</u> <u>a number</u>." | 16 times a number means "16x" | Two more than just means add 2.

(16x + 2)

-- "Is the same as" means equals.

(16x + 2) =

-- <u>21 less than</u> <u>the product of -7</u> and <u>the number</u> | The product of -7 and the number means "-7x" | 21 less than means subtract 21.

(16x + 2) = (-7x - 21)

-- solve for x.

(16x + 7x) = (-21 - 2)

-- combine like terms.

23x = -23

-- Divide.

x = -1

Solve 6.1−0.3≥c+1. <br> please help me
horsena [70]

Answer:

c≤  24/25

​

Step-by-step explanation:

"0.3" was replaced by "(3/10)". 2 more similar replacement(s). Simplify 3/10

    61     3      

 (—— -  ——) -  (c + 1)  ≥ 0    then simplify 61/10

  10    10    

3.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

    61 - (3)                   29

————————  =  ——

     10                          5

29    

 —— -  (c + 1)  ≥ 0  

 5    

4.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

            c + 1     (c + 1) • 5

   c + 1 =  —————  =  ———————————

              1            5      

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Rewrite the whole as a fraction using  5  as the denominator :

                         c + 1     (c + 1) • 5

   c + 1 =  —————  =  ———————————

                             1            5    

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

                              29 - ((c+1) • 5)     24 - 5c

————————————————  =  ———————

                                          5                5

    24 - 5c

 ———————  ≥ 0  

      5    

 

Multiply both sides by  5  

5.2    Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     5c-24  ≤ 0

5.3    Divide both sides by  5  

     c-(24/5)  ≤ 0

5.4      Add  24/5  to both sides

            c ≤ 24/5

In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the l
Ymorist [56]

The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

We have to determine

In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the loan is repaid, as it appears in the following formula?

<h3>What formula is used to calculate the monthly payment?</h3>

The value of the monthly payment is given by;

\rm P=PV\times \dfrac{i}{1-(1+i)^{-n}}

Where,

  • PV is the present value or the amount of the loan.
  • i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.
  • n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.

Therefore,

The value should be used for n, the number of periods over which the loan is repaid;

n = 6 years × 12 months/year = 60 months = 60 periods.

Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

A coin is tossed 4 times. what is the probability of getting 4 tails?
Brrunno [24]

Answer:

2

Step-by-step explanation:

We know that P(Tail) = 1/2 and you want that to happen 4 times:

P(4Tails) = (1/2)(1/2)(1/2)(1/2)

P(4Tails) = 2

<em>You multiply because it is an </em><em>and</em><em> situation.</em>
