Answer:
The number of small and large boxes purchased are:
2 small boxes.
6 large boxes.
Step-by-step explanation:
To solve the unknowns, two equations must be established with the information provided:
150X + 400Y = 2700 (the price of the boxes and the final number of nails, where X is the small boxes and Y the large boxes)
Y = 3X (Large boxes are triple the small ones)
Then equation 2 is replaced in equation one and variable X is cleared:
150X + 400 (3X) = 2700
150X + 1200X = 2700
1350X = 2700
X = 2700/1350
X = 2
Finally, the value of X is replaced in equation 2 to find the number of large boxes:
Y = 3X
Y = 3 (2)
Y = 6

How many solutions does the equation have?
Answer:
Infinitely many
Step-by-step explanation:
They both equal the same equation
Answer:
All real numbers are solutions.
Step-by-step explanation:
4(z−5)+2=4z−18
Step 1: Simplify both sides of the equation.
4(z−5)+2=4z−18
(4)(z)+(4)(−5)+2=4z+−18(Distribute)
4z+−20+2=4z+−18
(4z)+(−20+2)=4z−18(Combine Like Terms)
4z+−18=4z−18
4z−18=4z−18
Step 2: Subtract 4z from both sides.
4z−18−4z=4z−18−4z
−18=−18
Step 3: Add 18 to both sides.
−18+18=−18+18

45 is what percent of 60 as an equation
Answer:
75% of 60 = 45
Step-by-step explanation:
In order to find the answer to this question you need to divide the percentage of the number by one-hundred and then divide that number by the number the number you are trying to find the percentage of.
60/x=100/75
(60/x)*x=(100/75)*x
60=1.33333333333*x
(1.33333333333) to get x
60/1.33333333333=x
45=x
x=45
75% of 60 = 45

Please give me the crown.
~Happy Helper~
Based on the temperature change and the amount of time it did so, the average change in temperature per hour is -3.5°F.
The average change in temperature per hour can be found by:
= Temperature change / Number of hours
Solving would give:
= -23.8 / 6.8
= -3.5°F
We can therefore conclude that in every hour of this cold day, the temperature changed by an average of -3.5°F.

Answer
Step-by-step explanation:
i really need help with it
The distance between M and C is √61 and distance between M and H is 13√2.
What is distance formula?The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula.
Assume that 'd' is the distance between A and B.
d =√(x2 - x1)² + (y2 - y1)²
Given coordinates:
M(6, -7) and a line that contains C(-6, -2) and H(-1, 10).
Now, distance between M and C
=√(-6 -6)² + (-2 + 7)²
=√36 + 25
= √61
and, MH
=√(-1-6)² + (10 +7)²
=√49+ 289
= √ 338
= 13√2

Let C be the event that a randomly chosen person went to college. Let J be the event that a randomly chosen person has a job. Identify the answer which expresses the following with correct notation: Given that the person went to college, the probability that a randomly chosen person has a job.
The probability of event J, followed by event C is occurred is P( J | C)
What is probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
Experiment: A trial or procedure carried out to generate a result is referred to as an experiment.Sample Space: A sample space is the collection of all potential results of an experiment. Tossing a coin, for instance, has two possible outcomes: head or tail.Favorable Consequence: An occurrence is deemed to have generated the desired outcome or an anticipated event if it did so.Trial: To conduct a trial is to conduct a random experiment.The given case is case of Conditional Probability.

In 60 seconds , Darrell walks 90
90
meters. Describe the unit rate at he wall
Answer:
1.5 sec by meters
Step-by-step explanation:
90 meters/60 sec=1.5
Darrel walks at a unit rate of 1.5 m/sec.
What is speed?Speed is defined as the rate of change of position in unit time.
Mathematically,
Speed = Distance/Time
Now it is given that,
Distance in walk by Darrell = 90 meters
Time taken by Darell to walk 90 meters = 60 seconds
Therefore Speed i.e unit rate of walk is given as,
Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters
⇒ Unit rate of walk = 90/60 m/sec
⇒ Unit rate of walk = 3/2 m/sec
⇒ Unit rate of walk = 1.5 m/sec
Thus, Darrel walk at a unit rate of 1.5 m/sec.

Answer:
y = -2
Step-by-step explanation:
The graph passes through (0,0) and (-1,2).
The equation of a line passing through the origin is of the form,
y = mx

FG is an altitude of Triangle EFH19) If manish saves 40% percent of his monthly income and he spends Rs. 15,000 every month, find his monthly income.
Answer:
Rs 25000
Step-by-step explanation:
Saves 40%
Spends 60%
Spending 60% = 15000
If 60% = 15000
Then divide it by 6 to get 10%
10% = 15000 ÷ 6
10% = 2500

What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.
Parallel lines are those lines in which slopes are the same and the distance between them remains constant.
Given the two lines a and b as parallel.
If we want to show any two lines as parallel then we use |the | sign in between them.
Now in the given figure, A B C D are points on lines a and b so they will not be used to show parallel lines.
