Answer:
3y means 3 * y
Step-by-step explanation:
I think it is written as 3y instead of 3*y or 3 x y because, 3*y is a bit too cluttered, and 3xy or 3 x y means (Three times X times Y) because X is its own variable.
In other words, 3y means 3 times y
In any of the mathematical problem, the value of 3y will be 3 × y.
What is a mathematical problem?
A mathematical problem is any issue that may be modeled, examined, and potentially resolved using mathematical techniques. This can be a practical issue, like calculating the orbits of the solar system's planets, or a more theoretical issue, like Hilbert's conundrums.
In other cases, such as Russell's Paradox, it can also represent an issue with the very nature of mathematics. Building a mathematical model of the issue is typically the first step in applying mathematics to a real-world situation.
In order to translate the original problem into a mathematical one, it is necessary to abstract from the specifics of the problem, and the modeler must be careful not to lose key features in the process.
Therefore, in any of the mathematical problem, the value of 3y will be 3 × y.

x+5y, equals, minus, start fraction, 1, divided by, 3, end fraction, x, plus, 5.
Given the equation of the graph, the slope is -1/3 and The two points in the graph are ( 0, 5 ) and ( 3, 4 ).
What is the graph of the equation?Given the equation y = -1/3x + 5
Using the slope intercept form; y = mx + b
Hence,
Slope m is -1/3
y-intercept = ( 0, 5 )
From the equation, y = -1/3x + 5
All lines can be graphed using two points, we select two x values and plug it into the equation; 0 and 3
For x = 0
y = -1/3x + 5 = -1/3(0) + 5 = 5
For x = 3
y = -1/3x + 5 = -1/3(3) + 5 = -(3/3) + 5 = -1+5 = 4
Hence, the slope is -1/3 and The two points in the graph are ( 0, 5 ) and ( 3, 4 ).

Step-by-step explanation:
- 5x + 2 = 17 -- x = 3
- 3x + 5 = 36 -- x = 10.333
- x/3 - 14 = 9 -- x = 7.667 (Might be wrong)

5/6 years into months
Answer: If this would be division the answer would be 1.2
Step-by-step explanation: I hope this helped.
Answer:
10 months
Step-by-step explanation:
To answer this question, we must first remember than there are 12 months in a year. So, if we can make the denominator (bottom number) of the fraction 12, we can solve this problem easier. We can see the current denominator is 6, and if we multiply that by 2 we get 12, but remember that whatever you do to the bottom, you must also do to the top. So, multiply both numbers by 2 to get:
10/12
Meaning, that 10/12 of a year is 10 months

Here is my question! first gets brainliest!!!! the question is in the picture,
Answer:
8 dimes, 15 quarters
Explanation:
The number of dimes=x
The number of quarters=x+7
So the value of each dime and quarter is 0.10 and 0.25
0.1x+0.25(x+7)=4.55
0.1x+0.25x+1.75=4.55
0.35x+1.75=4.55
0.35x+1.75–1.75=4.55–1.75
0.35x=2.8
0.35x/0.35=2.8/0.35
x=8
So the number of dimes there are is 8.
The number of quarters:
x+7
=8+7
=15
So, the number of dimes and quarters in this order are: 8 and 15.

The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation
F=9/5 C+32
1.In the Sahara desert, temperatures often reach 50 degrees Celsius. How many degrees Fahrenheit is this?
2.In parts of Alaska, the temperatures can reach -60 degrees Fahrenheit. How many degrees Celsius is this?
3.There is one temperature where the degrees Fahrenheit and degrees Celsius are the same, so that C=F. Use the expression from the equation, where F is expressed in terms of C, to solve for this temperature.
The temperatures are in 50° Celsius, -60° Celsius and -40° Celsius when the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit respectively.
What is the temperature?Temperature is a measurement of an object or material's warmth or coldness and an expression of thermal energy.
Given, the conversion expression of degrees Fahrenheit to degree Celsius.
The expression is,
F = (9/5)C + 32
For the option 1,
C = 50° Celsius
Then F = 9 x 50/5 + 32
= 90 +32
= 122° Fahrenheit
For the option 2,
C = -60° Celsius
Then F = 9 x -60/5 + 32
= -108 + 32
= -76° Fahrenheit
For the option 3,
C = F
Then F = 9F / 5 +32
F - 9F/5 = 32
-4F / 5 = 32
F = -160/4
F = -40° Celsius.
Therefore, the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit when the temperatures are in 50° Celsius, -60° Celsius and -40° Celsius respectively.
