Answer:

-0.85, 0.09, 3/20, 0.3, 2/5, 3/4

Step-by-step explanation:

Turn all the fractions into decimals

2/5 -> .4

3/4 -> .75

3/20 -> .15

Then order them

-.85, 0.09, 0.15, 0.3, 0.4, 0.75

5. Find the first, fourth, and tenth terms of the arithmetic

Lubov Fominskaja [6]

The first, fourth and tenth terms of the arithmetic sequence is $-6, -\frac{27}{5}$ and $-\frac{21}{5}$

Explanation:

The given rule for the arithmetic sequence is $A(n)=-6+(n-1)(\frac{1}{5} )$

We need to determine the first, fourth and tenth terms of the sequence.

To find the first, fourth and tenth terms, let us substitute $n=1,4,10$ in the general rule for the arithmetic sequence.

To find the first term, substitute $n=1$ in $A(n)=-6+(n-1)(\frac{1}{5} )$ , we get,

$A(1)=-6+(1-1)(\frac{1}{5} )$

$A(1)=-6+(0)(\frac{1}{5} )$

$A(1)=-6$

Thus, the first term of the arithmetic sequence is -6.

To find the fourth term, substitute $n=4$ in $A(n)=-6+(n-1)(\frac{1}{5} )$ , we get,

$A(2)=-6+(4-1)(\frac{1}{5} )$

$A(2)=-6+(3)(\frac{1}{5} )$

$A(2)=\frac{-30+3}{5}$

$A(2)=\frac{-27}{5}$

Thus, the fourth term of the arithmetic sequence is $-\frac{27}{5}$

To find the tenth term, substitute $n=10$ in $A(n)=-6+(n-1)(\frac{1}{5} )$ , we get,

$A(10)=-6+(10-1)(\frac{1}{5} )$

$A(10)=-6+(9)(\frac{1}{5} )$

$A(10)=-6+\frac{9}{5}$

$A(10)=-\frac{21}{5}$

Thus, the tenth term of the arithmetic sequence is $-\frac{21}{5}$

Hence, the first, fourth and tenth terms of the arithmetic sequence is $-6, -\frac{27}{5}$ and $-\frac{21}{5}$

The temperature dropped from 75° to 50° what is the percent decrease in the temperature

Soloha48 [4]

Percent change is

(New - old) / old

50 - 75 / 75

25 / 75 = .33333333....

To convert to a percent, multiply by 100

Percent decrease = 33.33%

(5p+11)-(3p+7)=-4

fiasKO [112]

Step 1 :Pulling out like terms :

1.1 Pull out like factors :

2p + 8 = 2 • (p + 4)

Equation at the end of step 1 : Step 2 :Equations which are never true :

2.1 Solve : 2 = 0

This equation has no solution.
 A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : p+4 = 0

Subtract 4 from both sides of the equation :
 p = -4

One solution was found : p = -4
