Chevy has some yarn that he wants to use to make hats and scarves. Each hat uses
0.2
0.20, point, 2 kilograms of yarn and each scarf uses
0.1
0.10, point, 1 kilograms of yarn. Chevy wants to use
2
22 kilograms of yarn to make a total of
15
1515 items.
Let
h
hh be the number of hats Chevy makes and
s
ss be the number of scarves he makes.
Which system of equations represents this situation?

answer

you start with $5 and save $10 a week until you have at least $45wer

step-by-step explanation:

20days louise can read300 pg

step-by-step explanation:

1 day 15 pg 300: 15= 20

x day 300 pg

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
