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: 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

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

im not for sure but I think the answer is 9! my reasoning is below,,

Step-by-step explanation:

[tex] \frac{49}{7} = \frac{63}{x} [/tex]

do the crossing method and it would result in this

(49×x) = (63×7)

after simplifying both sides

49x = 441

divide both sides by 49 and the result will be

x = 9 !!

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: Is it not 6km an hour?

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

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
