A linear model of this situation contains the values (15, 300.2) and (26, 177.88) where x represents the number of square inches knitted on the scarf and y represents the number of yards remaining on the ball of yarn. How many yards of yarn did Paula start with?

Paula starts with 301.5 yarns.

Step-by-step explanation:

Equation of a line passing through two points (a,b) and (c,d) is given by:-

Given: x=  number of square inches knitted on the scarf

y= number of yarns remaining on the ball of yarn

The equation of a line passing through (15, 300.2) and (26, 177.88):

To find initial point, put x=0

Hence, Paula starts with 301.5 yarns.

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
