if the temperature is 50 degrees Fahrenheit what is the temperature in celsius

Answer:

x = 6 or x = -5

Step-by-step explanation:

x^2 - 30 = x

x^2 - x - 30 = 0

(x - 6)(x + 5) = 0

x - 6 = 0 or x + 5 = 0

x = 6 or x = -5

Answer: 2x-9y=1

Step-by-step explanation:

(this is how i found it don't know if this is how you learned it though)

Subtract 20 from both sides of -3x-8y=20, so that it becomes -3x-8y-20

Subtract 19 from both sides of -5x+y=19, so you get -5x+y-19

Subtract like terms from both equations (-3x-8y-20)-(-5x+y-19), which gives you 2x-9y-1

-3--5=2, -8-1=-9, -20--19=-1

Add 1 to both sides and you get 2x-9y=1

Answer: 1430

Step-by-step explanation: x + y + z = 2680  

x = 2z - 100  

y = 3z + 80  

x + y = 5z - 20  

6z - 20 = 2680  

z = 450  

y = 1430  

Solution:  

x = 800, y = 1430, z = 450

Step-by-step explanation:

Talia bought 4 watermelons for her annual watermelon summer party. She also spent an additional 9 dollars on the party supplies. The total amount she spent was less than 30 dollars. Write an equation to represent this word problem in which the amount of money each watermelon was is represented by x.

Answer:

m = -2

Step-by-step explanation:

m - 5 - 6m = 5

First, you need to combine like terms

-6m + m = -5m

-5m - 5 = 5

Next, add 5 to both sides of the equation

-5m - 5 = 5

    + 5   + 5

-5m = 10

Divide -5 by both sides of the equation

-5m = 10

÷-5    ÷-5

m = -2

Answer:

8 + f = 385

Step-by-step explanation:

8 added to f is the same as 8 + f.

The equal sign is basically "same as"

So 8 + f is "same as" 385.

Answer:

377

Step-by-step explanation:

8 + f = 385

subtract 8 from 385

385 - 8 = f

f = 377

Answer:

x= 3

Step-by-step explanation:

1. -5(3) + 2 = -13      

2. -15 + 2 = -13         A positive times a negative will always equal a negative

3. -13 = -13         Whenever you add anything to a negative number, the                    

                           number becomes smaller  

                     Ex:  -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, ...........

                           Although the number itself becomes smaller, its value    

                            becomes bigger      

Hope this helps.

Answer:

f(-3) = 7

Step-by-step explanation:

For these types of questions, you need to replace the x's in the equation with whatever is inside f(x)

So if its f(5) you would sub 5 into where all the x's are

Answer:

0.0637

Step-by-step explanation:

hope this helps :)

6.37 x 10⁻² in the standard form is 0.0637.

Decimals are numbers that have two components, a whole number component and a fractional component, which are separated by a decimal point.

We have an expression,

6.37 x 10⁻².

Simplifying to standard form.

6.37 x 10⁻²,

= 6.37 x 1/100

= 6.37/100

= 0.0637

Therefore, 0.0637 is the standard form.

Answer:

x = 20

Step-by-step explanation:

these angles are supplementary, which means they add up to 180°

using this, you can make the following equation:

6x + 60 = 180

subtract 60 from both sides of the equation

6x + 60 - 60 = 180 - 60

6x = 120

divide both sides of the equation by 6

6x/6 = 120/6

x = 20

Answer:

2/5

Step-by-step explanation:

You divide 12 by 6 and 30 by 6.

PLEASE MARK BRAINLIEST!!!!

The fraction 12 / 30 in the simplest form is 2 / 5.

Fractions are numbers that are written in 2 parts: a numerator and a denominator.

The upper part is the numerator while the lower part is the denominator.

Therefore, let's solve the fractions to it simplest form.

Simplified fractions are the fractions in their lowest, reduced and simplest form.  In other words, a fraction is said to be in its simplest form if 1 is the only common factor of its numerator and denominator.

Therefore,

12 / 30 ÷ 6 / 6 = 2 / 5

Answer:

The pounds of roasted pistachios nuts Christopher purchases is 10 pounds

Step-by-step explanation:

The given parameters are;

The price of raw almonds at Nuts.com = $8 per pound

The price of roasted pistachios at Nuts.com = $9 per pound

The amount Christopher spends on Nuts = $162

The quantity of nuts Christopher purchase = 19 pounds

Let the pounds of raw almonds nuts Christopher purchases = X and the pounds of roasted pistachios nuts Christopher purchases = Y

∴ $8·X + $9·Y = $162...(1)

X + Y = 19...(2)

Making X the subject of the formula in equation (2), we have;

X = 19 - Y

Substituting the value X in equation (1) gives;

$8·(19 - Y) + $9·Y = $162

$152 - $8·Y + $9·Y = $162

$1·Y = $162 - $152 = $10

Y = $10/($1) = 10

Y = 10 pounds

The pounds of roasted pistachios nuts Christopher purchased = Y = 10

The pounds of roasted pistachios nuts Christopher purchases = 10 pounds

X = 19 - Y = 19 - 10 = 9

X = 9 pounds

The pounds of raw almonds nuts Christopher purchases = X = 9

The pounds of raw almonds nuts Christopher purchases = 9 pounds
