Answer:
what
Step-by-step explanation:
<span><span /><span>In this problem, we are looking for the total
inches of ribbon that Risa needed in order to complete sewing all sides of the
Blanket.
She needs 72 inches per sides of the blanket.
A blanket is consisting of 4 sides, therefore multiply 72 by 4.
=> 72 x 4
=> 288 inches
or simply add 4 72s
=> 72 + 72 + 72 + 72
=> 288 inches</span></span>
(-9,-2) (1,3)
slope = (3 - (-2) / (1 - (-9) = 5/10 = 1/2
y - y1 = m(x - x1)
slope(m) = 1/2
(1,3)...x1 = 1 and y1 = 3
sub
y - 3 = 1/2(x - 1)
y - 3 = 1/2x - 1/2
y = 1/2x - 1/2 + 3
y = 1/2x - 1/2 + 6/2
y = 1/2x + 5/2 <=== slope intercept form
Answer:
and


Step-by-step explanation:
Let the variables be: x and y
The equations can be modelled as:
and

To solve for x and y, we have:
Make x the subject in

Answer:
78 emails
Step-by-step explanation:
Given
Represent sent emails with x and received with y.
So, we have:
-- First statement
-- Second statement
