x/2-4/5+x/5+3x/10=1/5​

Answers

Answer 1

Answer:

x = 1

Step-by-step explanation:

Given

[tex]\frac{x}{2}[/tex] - [tex]\frac{4}{5}[/tex] + [tex]\frac{x}{5}[/tex] + [tex]\frac{3x}{10}[/tex] = [tex]\frac{1}{5}[/tex]

Multiply through by 10 ( the LCM of 2, 5 and 10 ) to clear the fractions

5x - 8 + 2x + 3x = 2 , that is

10x - 8 = 2 ( add 8 to both sides )

10x = 10 ( divide both sides by 10 )

x = 1

Two friends, Aria and Kaylee, took summer jobs. The equation y = 20.2 x y=20.2x represents Kaylee's earnings in dollars and cents, y y, for working x x hours. Aria earned $737.20 in 38 hours.

Answers

Answer:

y=19.4x------represents Aria's earnings in dollars and cents,

Step-by-step explanation:

The question is not complete, however, the idea from this response can provide the needed solution and understanding

 Step one:

The linear function for the earnings is given as

y = 20.2x-----this represents Kaylee Earnings.

y represents the total earnings

x represents the earning rate, in this situation it $20.2 per hour, this is also the gradient of the function m

Step two:

we want to find th equation for Aria earning

y= $737.20

time taken x=38 hours

737.2=m(38)

divide both sides by 38

m=737.2/38

m=19.4

this means that Aria earn $19.4 per hour

the function for Aria is

y=19.4x

1. What is the probability of an odd outcome?

2. What is the probability of an outcome less than 6?

Answers

Answer:

1. 50%

2.[tex]\frac{5}{6}[/tex]

Step-by-step explanation:

1. The way to approach the probability of rolling an odd number is to start with the total numbers. Therefore, each dice has three even sides and three odd sides. Mathematically - 50% chance of landing on the odd number.

2. You have 'P' which represents probability. "N" which is the given ratio of the number of outcome. (NP) total number of the possible outcome.

P = N / NP

Dice has 6 faces. I.E. 1,2,3,4,5,6

= 6

NP, therefore, is the total number of possible outcome.

Faces less than 6. (1,2,4, and 5)

N = 5

P = N / NP = [tex]\frac{5}{6}[/tex] ; it can't be reduced.

?

Answers

Answer:

n5 + 17

Step-by-step explanation:

They're asking for a pattern.

17 + 5 = 22

22 + 5 = 27

27 + 5 = 32

So it starts at 17 and increases by five each time.

The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.

n5 + 17

Help me find a 3rd degree binomial

Answers

Step-by-step explanation:

A binomial expression has two terms. For example, 4x + 5,

The degree of any polynomial refers to the term with the highest exponent on its variable. For example, In expression 4x + 5, the exponent of x is 1 so it is 1st degree polynomial and in the same way, for  since the variable y has the highest exponent i.e., 2 therefore it is 2nd degree polynomial.

Now, third degree binomial with constant term 8 =

As it has two terms where first term is  and second term is 8. Therefore, it is called binomial and since the highest exponent with variable x is 3, therefore it is third degree binomial with constant term of 8.

At cultutral arts day each session lasts 4/5 hours. The principal has set aside 3 hours for the sessions. Determine the number of sessions that can be sheduled for each student

Answers

Answer: 3.75

Step-by-step explanation:

The following can be gotten from the question:

Time taken for each session = 4/5 hours

Total time set aside by principal = 3 hours

The number of sessions that can be sheduled for each student will be:

= Total time set aside by principal / time taken for each session

= 3 hours / 4/5 hours

= 3 × 5/4
