Full question:
The longest side of an obtuse triangle measures 20 cm. The two shorter sides measure x cm and 3x cm. Rounded to the nearest tenth, what is the greatest possible value of x?
Answer:
5
Step-by-step explanation:
Note: an obtuse triangle is a triangles in which one of the interior angles is more than 90 degrees. Sum of angles in triangle =180 degrees
The longest side of a triangle here is the hypotenuse. To find the unknown side of a triangle, we use the Pythagorean theorem. We already know the hypotenuse hence:
20= √(x²+3x²)
20=4x
x=20/4=5
x= 5
Which situation CANNOT be represented by this equation? 6x−7=29

BJoel mows his aunt's lawn for $6 per hour. If he spends $7 on gas, how many hours, x, will he need to spend mowing the lawn to have $29 left?
C)Joel takes 6 hours to mow his aunt’s lawn. If he spends $7 on gas, how much does he get paid per hour, x, to mow the lawn and still have $29 left?
9514 1404 393
Answer:
A
Step-by-step explanation:
The unit rate in scenario A is 7, not 6, so it is inappropriate to use the equation 6x -7 = 29 for that scenario.
Situation A cannot be properly represented by the given equation.

Consider the equations y = 2x - 3 and y = 3x - 6. Solve the system of equations by completing the table to find an ordered pair that satisfies both equations.
A) (0, 3)
B) (1, -1)
C) (2, 2)
D) (2, 2)
Answer:
2,2
Step-by-step explanation:
Equations are all good
The ordered pair (2, 1) satisfies the given equations. Therefore, the answer is option (C).
To solve the system of equations y = 2x - 3 and y = 3x - 6, we need to find an ordered pair (x, y) that satisfies both equations.
We can do this by completing the table of values for each equation and finding the values of x and y that make both equations true.
For the equation y = 2x - 3, we can complete the table as follows:
x: -1, 0, 1, 2, 3
y: -5, -3, -1, 1, 3
For the equation y = 3x - 6, we can complete the table as follows:
x: -1, 0, 1, 2, 3
y: -9, -6, -3, 0, 3
From these tables, we can see that the ordered pair (2, 1) satisfies both equations.
Therefore, the answer is (2, 1).

Answer: The independent variable is the days, and the dependent is the amount of sales.
Step-by-step explanation:
The days are independent because there is no way to change it, and it will always be. (like a schedule depends on time)
The sales are dependent because they rely on the days, especially because you can't sell things without there being time.

Add 5 for the first one
The 2nd one is 25 and k or 25 thousand.
Step-by-step explanation:
add 5 for the first one because 5 + 5 = 10
9 + 5 = 14 . and 13 + 5 = 18.
------------------------------------------------------------------
For the 2nd one: 25k means 25 thousand or the Product of 25 and k.

how do I make fractions into mixed numbers??? like 3 8/4
Answer:
look down
Step-by-step explanation:
OK so u take something like 9/3 and then ask how many times the 3 goes into the 9 and that is your whole number. whatever is left is your top of the fraction and the bottom stays the same hope this helped
Answer:
To make an improper fraction into a mixed fraction:
1. Divide the numerator by the denominator
2. Write down the whole number answer
3. Then write down any remainder above the denominator
Example:
Turn 8/3 into a mixed fraction.
8 ÷ 3 = 2 R2
So... 2[tex]\frac{2}{3}[/tex]
To make a mixed fraction into an improper fraction:
1. Multiply the whole number part by the fraction's denominator.
2. Add that to the numerator.
3. Then write the result on top of the denominator.
Example:
Turn 4[tex]\frac{6}{7}[/tex] into an improper fraction.
4 x 7 = 28
28 + 6 = 34
So... [tex]\frac{34}{7}[/tex]

convert the body temperature of 36.4°C to °F?
Answer:
97.52
Step-by-step explanation:
First, we need to know the formula to convert Celsius into Fahrenheit.
Given, [tex]F= \frac{9}{5} C +32[/tex], let us plug in what we know, 36.4 C, into the equation!
[tex]F=\frac{9}{5} * 36.4 +32\\F= 65.52 +32\\F= 97.52[/tex]
Therefore, a body temperature of 36.4 C would be 97.52 Fahrenheit!
I hope this helps! Please let me know if you have any further questions :)
The value of temperature will be 97.52° F.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The value of temperature = 36.4° C
Now,
We know that;
The relation between the degree and Fahrenheit is,
⇒ F = 9/5 C + 32
⇒ F = 9/5 × 36.4 + 32
⇒ F = 65.52 + 32
⇒ F = 97.52
Thus, The value of temperature = 36.4° F
