Compare the models for 1/3 and 2/6 how dose the number of parts relate to the sizes of the parts

1 answer:

6 0

There is no model attached, but, we can imagine a model.
Take a whole pizza.
There’s six slices and you have three friends.
You want it to be even and so each friend gets two slices.
But, originally, the pizza could’ve been sliced into three bigger pieces anyways.
1/3 = 2/6

Find a linear equation that is perpendicular to y= 2x + 4 and passes through (-5, -3)

Trava [24]

Answer:

y=-1/2x+7/2

Step-by-step explanation:

two lines are perpendicular if the product of the slopes is equal to -1

the slope for y=2x+4 is 2

2*x=-1

x=-1/2

the formula for the slope is

(y2-y1)/(x2-x1)=m

we know y1 and x1

(y+5)/(x+3)=-1/2

y+5=x+3/2

2y+10=x+3

2y=x-7

y=-1/2x+7/2

A bike shop rents each of its mountain bikes for a one time $4.00 insurance charge plus $2.50 per hour create an equation that r

egoroff_w [7]

Answer:

$y=2.50x+4.00$

Step-by-step explanation:

Let

x -----> the number of hours

y ----> the total cost to rent a bike in dollars

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope or the unit rate of the linear equation

b is the y-intercept or the initial value

In this problem we have

The unit rate or slope is equal to

$m=\$2.50\ per\ hour$

The y-intercept (value of y when the value of x is equal to zero) is equal to

$b=\$4.00$ ----> (fee charge)

substitute the values

$y=2.50x+4.00$

$2 \: ( \: x + 1 \: ) - 3$

Plugging in the value " $x\:=\:6$ " in the above expression, we have

$= 2 \: ( \: 6 + 1 \: ) - 3$

$= 2 \: ( \: 7 \: ) - 3$

$= 14 - 3$

At noon joyce drove to the lake at 30 mph, but she made the long walk back home at 4 mph. how many hours did she walk if she was

lina2011 [118]

By definition we have the following equation:
t = d / v
Where,
t: time
d: distance
v: speed
For this case we have:
d / 30 + d / 4 = 17
Rewriting we have:
2d + 15d = 17 (60)
17d = 17 (60)
d = 60 mi
Then, the walking time is
t = d / v
t = 60/4
t = 15 hours
Answer:
She walked
t = 15 hours
