Natasha has a job putting letters in envelopes to be mailed. in 1 hour she put 42 letters in envelopes. which equation best represents y, the total number of letters natasha puts in envelops in x hours if she continues
Answer:
36 pages .394kb
Step-by-step explanation:
that's it well done
You can use multiplication along with converting statements to symbols.
The equation for the given condition is given by [tex]y = 42x[/tex]
where y represents the total number of letters Natasha puts in envelops in x hours.
How to form symbolic expressions from the description?You need to know how to convert the statement to symbolic expression.
Suppose if it is said that a thing is increased by 4,then we write it as
that thing + 4
Suppose if it is written that 'x' objects are sold on p price per object. Since 1 object is sold at p price, then x objects will be sold at:
[tex]p + p + ... + p \: \: \: (x \: \: times) = p \times x[/tex]
Such conversion can help us to form symbolic expressions from the given description.
Since for the given case, in 1 hour, Natasha put 42 letters in envelopes, then in x hour she will put:
[tex]42 + 42 + ... + 42 \: \: (x \: times) = 42 \times x[/tex]
Since in x hours, she puts y envelopes but envelopes put in x hours came out as 42 times x, thus, both the values are equal, or
[tex]y = 42 \times x = 42x \text{\:\:(written in short)}[/tex]
The equation for the given condition is given by [tex]y = 42x[/tex]
where y represents the total number of letters Natasha puts in envelops in x hours.

Anna pays $5.50 each day to park in a parking deck. How much will she pay for 5 days of parking?
Answer:
27.5 :))
Step-by-step explanation:
so this is the way i did it i breaked it down right so the equation is 5.50 x 5
take away the decimal and now its 550 and i did repeative addition of 5 until i got 2's of 1,100 i added them up then added the 2,200 + 550 without the decimal and i got 2750 instead of adding ',' i took the number 5.50 and saw there were two spaces under the numbers before it got to the decimal and it was two spaces so you do two hops like you do on a line in math so it basically turns to 27.50 :)) but you always take away the 0 if theres no number behind it so it turns to 27.5 :) but if the questions dont have the answer 27.5 then just add the 27.50! its the same number anyways :D ( i hope you understand it!)
Answer:
$27.5
Step-by-step explanation:
All you have to do is 5.50 multiplied by the number of days she is staying their, which is 5. Once you put that in, you get your answer which is 27.5!

x+4=3x+9 how to solve this?
Answer:
x = - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
x + 4 = 3x + 9 ( subtract x from both sides )
4 = 2x + 9 ( subtract 9 from both sides )
- 5 = 2x ( divide both sides by 2 )
- [tex]\frac{5}{2}[/tex] = x

John has 15 1/4 gallons of gas in his truck. John can drive his truck 7 1/2 miles on each gallon of gas. About how many miles can John drive his truck
Answer:
114 3/8 gallons
Step-by-step explanation:
To solve the question, we multiply by the number of gallons and the amount travelled per gallon:
Let's convert all fractions to improper fractions:
15 1/4 = (15*4 + 1)/4 = 61/4
7 1/2 = (7*2 + 1)/2 = 15/2
Multiply the numerators and the denominators:
61/4 * 15/2 = 61*15/4* 2 = 915/8 = 114 3/8

which statement best desonbes a graph of paired points that form a proportional relationship?
A straight line cannot be drawn through all the points and the line passes through the origin.
A straight line can be drawn through all of the the points but the line does not pass through the origin.
A straight line can be drawn through all the points and the lines passes through the point where x = 0 and y=0
A straight line can be drawn through all the points and the line passes through the point (3, 0).
Answer:
A straight line can be drawn through all the points and the line passes through the point where x=0 and y=0. This best describes a graph of paired points that form a proportional relationship.
Write the equation of the line in fully simplified slope intercept form
Answer:
y = -0.5x - 7 or y = -1/2x - 7 (both are same)
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
-9 - (-8) / 4 - 2 = -1/2 = -0.5
m = -0.5
b = y-intercept
b = -7
y = mx + b
y = -0.5x + (-7)
y = -0.5x - 7
(negative slope)
