Solve a) 2(x+3)=x-4 b) 4(5x-2)=2(9x+3)
Answer:
a) -10 b) 7
Step-by-step explanation:
a) 2(x+ 3) = x - 4
2x + 6 = x - 4
2x - x = -6 - 4
x = -10
b) 4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 14/2
x = 7
Answer:
a=
[tex]x = - 10 \\ x = 7[/tex]
[tex]2x + 6 = x - 4 \\ 2x + 6 - x = - 4 \\ x + 6 = - 4 \\ x = - 4 - 6 \\ x = - 10 \\ \\ \\ 20x - 8 = 2(9x + 3) \\ 20x - 8 = 18x + 6 \\ 20x - 8 - 18x = 6 \\ 2x - 8 = 6 \\ 2x = 6 + 8 \\ 2x = 14 \\ x = \frac{14}{2} x = 7[/tex]

You need at least 15 pencils or markers. You want to spend at most $14 on pencils and markers. Pencils p are $0.85 each and markers m are $1.45 each. Which system of inequalities models the situation?
Answer:
.85p + 1.45m <= 14
Step-by-step explanation:
You don't want to spend more than 14, but you can spend 14. So the inequality must be less than or equal to. To find the combination of pencils and markers you must multiply their price times the number of pencils. Sorry if this explanation isn't amazing, I know how to do work but not explain my reasoning. :)

B. y≥-2x+3
y≥x+3
C. y≤-3x+2

Answer: A
Step-by-step explanation:
The answer is A.
y≤-2x+3 .... (1)

How many solutions does the following system of equations have? y=5/2x+2 and 2y=5x+8
Answer:
No solutions.
Step-by-step explanation:
y = 5/2x + 2
2y = 5x + 8
Plug the first equation into the second.
2(5/2x + 2) = 5x +8
5x + 4 = 5x + 8
5x + 4 cannot equal 5x + 8, so this system of equations has no solutions.

Petra rolls a 6-sided die with faces numbered 1 through 6.
The probability she rolls an odd number.
Answer:
1/2 or 0.5
Step-by-step explanation:
The odd numbers through 1 to 6 are:
1, 3, and 5.
So there are 3 odd numbers out of 6 total faces or numbers.
3/6
Simplify the fraction to the lowest terms.
1/2 = 0.5
Answer:
P=1/2=0.5
Step-by-step explanation:
To find the probability, you must first find E(Event) and S(Sample space). so
E=3={1,3,5} which are the odd numbers from 1-6.
[tex]S=6^{n}[/tex] where n is the number of dices.
S=6 because there is one dice. So...

During a fancy fair organized at school, the total amount of money collected was $54 000. The following table represents the amount of money collected from the different items:
Food and drinks: 27 000
Entertainment: 6000
Games: 12 000
Donations: 9000
What percentage of the money collected does each item represent?
Answer: Collected amount÷total amount x 100
Step-by-step explanation:
Food and drinks = [tex]\frac{27000}{54000}[/tex] x 100 = 50%
Entertainment = [tex]\frac{6000}{54000}[/tex] x 100 = 11% (11.1 - .1 recurring)
Games = [tex]\frac{12000}{54000}[/tex] x 100 = 22% (22.2- .2 recurring)
Donations = [tex]\frac{9000}{54000}[/tex] x 100 = 17% (16.6- .6 recurring)
Double checking - 50 + 11 + 22 + 17 = 100%
Hope this helps! :)
Answer:
Food & drinks = 50%
Entertainment = 11.1%
Games = 22.2%
Donations = 16.7%
Step-by-step explanation:
Basically, divide all of the amounts to $54000.

Answer:
x=35
Step-by-step explanation:
Since a quadrilateral's interior angles add up to 360°, we get this:
360-85-20=360-4x+x
340-85=360-3x
255=360-3x
-105= -3x
Multiply both sides by -1
105=3x
3x=105
Divide both sides by 3

Alex drives at an average speed that is 3/4 of the average speed that Roy's train travels. Alex takes 40 minutes to travel 65 km in her car. Roy travels for 1 hour and 15 minutes on his train. How far does Roy travel to 2 dp?
Answer:
Distance = 162.5 to 2dp.
Step-by-step explanation:
Alex car drives 65km = 40mins we round up to 1hr
= 1/2 x 65 + 65 = 32.5 +65 = 97.5 km p/h
Roy is 1/4 faster (As Alex speed is 3/4 of Roy)
To find 3/4 we divide by 3 then, add the 97.5 km etc..
97.5/3 = + 32.5km = 130 km/ph
To check we only have to divide by 4
130 / 4 = 32.5
We know 32.5 is 1/4 we can add this on as 15minutes.
130 km = 1hr +
32.5 km = 15 mins
Distance = 162.5 km
Answer:
162.50 km
Step-by-step explanation:
Alex: 40 minutes for 65 km
speed = distance/time = (65 km)/(40 min) * (60 min)/(1 hr) = 97.5 km/h
Alex's speed = 3/4 of Roy's speed
Roy's speed = (Alex's speed)/(3/4) = (97.5 km/h)/(0.75) = 130 km/h
speed = distance/time
distance = speed * time
time = 1 hour + 15 minutes = 1 hour + 15/60 hour = 1.25 hour
distance = 130 km/h * 1.25 hour = 162.50 km

What are collinear points?An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two factors determine a line, two points are transparently collinear. If the points are in a line, then the points are collinear points.
Let A, B, C, and D be the collinear points. Then the condition of the collinear will be
AB + BC = AC
The cities A, B, and C, in respective order, lie approximately in a straight line. The distance from city A to city B is 100 miles. The distance from city A to city C is 110 miles.
The distance from city B to city C will be given as,
AB + BC = AC
100 + BC = 110
BC = 110 - 100
BC = 10 miles
The distance from city B to city C will be 10 miles.

5y^2 - 2 = 3y
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y^2 - 2 = 3y
5y^2 - 3y - 2 = 0
(5y + 2)(y - 1)
5y + 2 = 0 or y - 1 = 0
5y = -2 or y = 1
y = -2/5 or y = 1
Answer:
y = -2/5 or y = 1
Step-by-step explanation:
5y²-2 = 3y
Add -3y on both sides
5y²- 3y -2 = 0
Factorize.
(5y + 2)(y-1) = 0
(5y+2) = 0
Subtract 2 on both sides.
5y = -2
Divide 5 into both sides.
y = -2/5
(y - 1) = 0
Add 1 on both sides.
y = 1

According to a survey, 30% of US adults attend
church every Sunday. Suppose two adults from the
US are chosen at random. Let x represent the
number in this sample who attend church every
Sunday. Write the probability distribution of x.
Answer:
The probability distribution of x is given by
P(x) = ⁿCₓ pˣ (1 - p)ⁿ⁻ˣ
Where n is the number of trials, x is the variable of interest and p is the probability of success.
P(x = 0) = 0.49
P(x = 1) = 0.42
P(x = 2) = 0.09
Step-by-step explanation:
The binomial distribution has the following features:
• There are n repeated trials and are independent of each other.
• There are only two possibilities: US adults attend church every Sunday or US adults do not attend church every Sunday
• The probability of success does not change with trial to trial.
Let x represent the number in this sample who attend church every
Sunday, the probability distribution of x is given by
P(x) = ⁿCₓ pˣ (1 - p)ⁿ⁻ˣ
Where n is the number of trials, x is the variable of interest and p is the probability of success.
For the given case
Probability of success = p = 0.30
Number of trials = n = 2
Variable of interest = x = 0, 1, 2
For P(x = 0):
Here we have x = 0, n = 2 and p = 0.30
P(x = 0) = ²C₀(0.30⁰)(1 - 0.30)²⁻⁰
P(x = 0) = 0.49
For P(x = 1):
Here we have x = 1, n = 2 and p = 0.30
P(x = 1) = ²C₁(0.30¹)(1 - 0.30)²⁻¹
P(x = 1) = 0.42
For P(x = 2):
Here we have x = 2, n = 2 and p = 0.30
P(x = 2) = ²C₂(0.30²)(1 - 0.30)²⁻²
P(x = 2) = 0.09

What are term and whole life insurances?They both are life insurances in which the beneficiary is paid a lump sum upon death of the insured person.
The term life insurance lasts only for a certain duratrion of time.
The whole life insurance covers the whole lifetime of the insured person.
Both insurances provide a lump sum to the beneficiaries upon the death of the insured person and don't cover the medical and outpatient surgery cost of the insured person. They are covered under health insurance. So, option A is false.
The whole life insurance covers the whole lifetime of the insured person. There is no such 25-year maximum duration. So, option B is false.
The term life insurance features no such cash value component as the whole life insurance. So, option C is incorrect.
The term life insurance provides financial compensation to the beneficiaries if the insured person dies during a specified time. Whole life insurance covers the entire lifetime of the insured person. Option D is, thus, correct.
