Answer:
B
Step-by-step explanation:
Factors are the two numbers which you multiply to get your product which is the equivalent of a sum in multiplication terms. You are multiplying two and nine in this scenario so they'd be the factors.
Let w = the walking time
the total time is given as 1 hr, therefore (1-w) = running time
Walking dist and running dist is the same
Write a distance equation: dist = speed * time
3w = 9 (1-w)
3w = 9 - 9w
3w + 9w = 9
12w = 9
w = 9/12 = 3/4 hrs walking back
Answer:
y – 3 = 2(x – 10)
Step-by-step explanation:
In point-slope form, the equation is written ...
y -k = m(x -h) . . . . . . . for line with slope m through point (h, k)
If only the slope changes, only the value just outside parentheses changes. When the point is (10, 3) and the new slope is 2, the new equation is ...
y -3 = 2(x -10)
The value of x in the figure is 74
<h3>How to determine the value of x?</h3>
The attached image represents the missing part of the question.
From the attached image, the tangent lines are LM and NM.
Opposite angles of a quadrilateral add up to 180.
So, we have:
x + 106 = 180
Subtract 106 from both sides
x = 74
Hence, the value of x is 74

If 6.5x meters of rope is needed, Bill needs x meters of rope, Amy needs 0.5x meters of rope and Carmen needs 5x meters of rope.
Step-by-step explanation:
Step 1:
Assume Bill needs x meters of rope, Amy needs y meters of rope, and Carmen needs z meters of rope.
Amy needs a piece half as long as Bill's and Carmen needs 5 times as much rope as Bill.
So we have
and 
Step 2:
So the total rope needed 
So if x = 1, x = 1 meter, y = 0.5 meters, z = 5 meters, a total of 6.5 meters of rope.
So if x = 2, x = 2 meter, y = 1 meters, z = 10 meters, a total of 13 meters of rope.
