The question is asking how much time Susan spent moving toward her office. On the graph, the y-axis represents the distance Susan is from her office, so the amount of time she is moving toward her office is the amount of time the graph is going down.
As you can see, the graph is going down from the 10 to 16 minute marks and the 22 to 26 minute marks. In total, this is 20 minutes in which the graph is going down.
Therefore, Susan spends 20 minutes moving toward her office.

Answer:
Step-by-step explanation:
1/x - 7/104 = 3/52
1/x = 6/104 + 7/104 = 13/104
104/13 = x
Answer:
Tomas added 6 to both sides of the equation instead of subtracting 6.
Step-by-step explanation:
Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of granola that costs $2.00 per pound. The walnuts cost $6 per pound. He uses the equation 2x + 6y = 12 to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. He solves the equation for y, the number of pounds of walnuts he can buy.
Given:
2x + 6y = 12
where
x = number of pounds of granola y = number of pounds of walnuts
The correct solution to the problem
x = 3 pounds
2x + 6y = 12
2(3) + 6y = 12
6 + 6y = 12
Subtract 6 from both sides
6 + 6y - 6 = 12 - 6
6y = 6
Divide both sides by 6
y = 6/6
= 1
y = 1 pound
Tomas added 6 to both sides of the equation instead of subtracting 6.
Answer:
pi
Step-by-step explanation:
The radius of the circle is 10 units
The circumference of a circle is given by the formula:
C = 2 * pi * r
The diameter of a circle is twice the radius
d= 2r
We want the ratio of the circumference to the diameter
C/d = (2*pi*r)/ 2r
Canceling out the 2 and the r, we are left with pi
C/d = pi
