<em>Question:</em>
<em>Triangles PQR and RST are similar right triangles. Which proportion can be used to show that the slope of PR is equal to the slope of RT?</em>
Answer:
Step-by-step explanation:
See attachment for complete question
From the attachment, we have that:
First, we need to calculate the slope (m) of PQR
Here, we consider P and R
Where
becomes
--------- (1)
Next, we calculate the slope (m) of RST
Here, we consider R and T
Where
becomes
---------- (2)
Next, we equate (1) and (2)
<em>From the list of given options (see attachment), option A answers the question</em>
Answer:
Step-by-step explanation:
Given
Billy's Marble = x
Required
Determine a,b and c
a. Charlie's Marble
"5 more" means 5 + or + 5
Since Billy's Marble is represented with x, then Charlie's Marbles will be
b. Danny's Marbles
Having "8 fewer" means we have to subtract 8 from Billy's marble;
Since Billy's Marble is represented with x, then Danny's Marbles will be
c. Eric Marbles
Having "three times as " means we have to multiply Bill's marble by 3;
Since Billy's Marble is represented with x, then Danny's Marbles will be
