hope this helps :)
6.37 x 10⁻² in the standard form is 0.0637.
What is decimal?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.

what are the steps to solve m -5 - 6m 5
Answers
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

Answers
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

Nuts.com sells raw almonds for $8 per pound and roasted pistachios for $9 per pound. Christopher spends $162, before taxes and shipping, to purchase 19 total pounds of nuts. How many pounds of pistachios did Christopher purchase?
Answers
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

with the weight attached x. Write and solve a direct variation equation to
find the length of the spring when a 63 pound weight is attached.
Answers
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 !!
