Answer: x=1/2,-2

not sure if that is what you need

Step-by-step explanation:

Answer:

A. $80

B. $60

C. 4 Weeks

D. Sam might have to work more at his work or possibly lower the amount of money he needs to save.

Step-by-step explanation:

Hope this Helps!!

The number of weeks taken by Sam to save enough money is 17 weeks.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

a) Money Sam earns in one week = Money paid per hour * Number of hours per week

= 8×10

= $80

b) Money saved every week is

75% of 80

= 75/100 ×80

= 0.75×80

= $60

c) He can reach his goal of having $1,000 as an emergency fund.

Let the number of weeks taken by Sam to save enough money be x.

Now, 60x=1000

x=1000/60

x=17 weeks

d) School is starting in a few weeks and he wants to buy some new supplies including a backpack, pens and notebooks, and more.  

He estimates the total will be about $75.

So, Sam has to work one week extra to purchase his needs for school.

Therefore, the number of weeks taken by Sam to save enough money is 17 weeks.

Answer:

[tex]\left(a+4\right)\left(a-5\right)[/tex]

Step-by-step explanation:

Break the expression into groups.

=(a^2+4a)+(−5a−20)

Factor out a from a2+4a:     a(a+4)

Factor out −5 from −5a−20:     −5(a+4)

=a(a+4)−5(a+4)

Answer: 1/3

Step-by-step explanation:

Number of red marbles = 5

Number of blue marbles = 9

Number of yellow marbles = 8

Number of and black marbles = 6

Total number of marbles = 28

If Taylor pulled out a yellow one and didn't replce it, there'll be 27 marbles left since one has been removed, then the probability of picking blue marbles will be:

= Number of blue marbles / Total marbles

= 9 / 27

= 1/3

The probability of picking a blue marble is 1/3.

Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 2

  Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      4 • 2

  ——————————————————  =   —————

        L.C.M              18  

  R. Mult. • R. Num.       x

  ——————————————————  =   ——

        L.C.M             18

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

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

4 • 2 - (x)     8 - x

———————————  =  —————

    18           18  

Equation at the end of step

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 8-x

 ——— • 18 = 0 • 18

 18

Now, on the left hand side, the  18  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  8-x  = 0

Solving a Single Variable Equation:

4.2      Solve  :    -x+8 = 0

Subtract  8  from both sides of the equation :

                     -x = -8

Multiply both sides of the equation by (-1) :  x = 8

One solution was found :

x = 8

Answer: w=8/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

20 /3 =2(w+ ( 2 /3 )

20 /3 =(2)(w)+(2)( 2 /3 )(Distribute)

20 /3 =2w+ 4 /3

Step 2: Flip the equation.

2w+ 4 /3 = 20 /3

Subtract 4/3 from each side: 2w+ 4 /3 − 4 /3 = 20 /3 − 4 /3

Divide both sides by 2: 2w/ 2 =16  3 /2

Answer w=8/3

Answer:

1040 approx

Step-by-step explanation:

Given data

Rate = 2%

Population= 1000

Time = 2 years

We can apply the expression below to find the population after 2 years

A= P(1+r)^t

Substitute

A= 1000(1+0.02)^2

A=1000(1.02)^2

A=1000*1.0404

A=1040.4

Hence the population is 1040 approx

5 =  (x/2) +x

10 = x+2x

10 = 3x

10/3 = x  

let's check :  

5- 10/3 =  15/3 -10/3 = 5/3

(10/3) /2  =10/3 * 1/2 = 10/6 = 5*2/3*2 = 5/3

[tex]mean = \frac{(73 + 81 + 51 + 76 + 89 + 95 + 88)}{7} \\ = 79[/tex]

Answer:

79

Step-by-step explanation:

What is mean?  The mean is the same as an average. To find the mean, add all the letters together. Then, divide this sum by the total amount of numbers.

Step One: 73+ 81+51 +76+ 89+ 95+88= 553

Step Two: Divide by numbers, in this case, there are 7: 553/7= 79.

Finding the confidence interval, it is found that the percentages of residents that may favor replacing the equipment is be given by:

B. 54%.

The interval is given by the estimate plus/minus the margin of error. The range is twice the margin of error.

In this problem, we have that:

Hence the interval is given by:

(61% - 9%, 61% + 9%) = (52%, 70%).

Each of the values in the interval can be the percentage, hence option B is correct.

Answer:

P.y = [tex]4^{x}[/tex]

Step-by-step explanation:

From the given question, since Jesse sends the email to 4 people and the 4 people rebroadcast it to another 4 persons each. And this process continues for a required or given round x, then this is an example of an exponential function.

Thus, the number of emails sent for a given round can be expressed as;

                    y = [tex]4^{x}[/tex]

Therefore, the appropriate answer is y = [tex]4^{x}[/tex].

So that for four rounds (x = 4), the number of emails sent can be determined as;

y = [tex]4^{x}[/tex]

  = [tex]4^{4}[/tex]
