Mary is making pillows for her Life Skills class. She bought 2 1/2 yards of fabric. Her total cost was $15. What was the cost pe

dexar [7]

Cost of 2 1/2 yards= $15
cost of 1 yard=?
cost of one yard= 15/(2 1/2)
=15/5/2
=15/5*2
=3*2
=$ 6
so the cost of fabric for one yard will be $6

What is the present age of Alex if he is one- fourth the age of a his father and if the age of the father is doubled, it is 20 y

AURORKA [14]

take father's age as x

if it is doubled i.e 2x .we get the answer as 20 less than 100 which means 100-20=80

accordingly the equation will be 2x=80

x=40

given that ,

son is 1/4 th of his father

hence ,

son = 1/4×(x)

I.e, 1/4×40 =10

Hope it helps

Complete the description of the slope of the line that joins the points

Grace [21]

Answer:

The slope of the line that joins the points is negative.

i.e m = -6/5

Step-by-step explanation:

Taking two points from the graph to determine the slope

(-3, 4)

(2, -2)

Finding the slope between (-3, 4),(2, -2)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$ '

$\left(x_1,\:y_1\right)=\left(-3,\:4\right),\:\left(x_2,\:y_2\right)=\left(2,\:-2\right)$

$m=\frac{-2-4}{2-\left(-3\right)}$

$m=-\frac{6}{5}$

Therefore, the slope of the line that joins the points is negative.

i.e m = -6/5
