Time spent babysitting by Lucy = Tl = 4 hours
Time spent babysitting by Maria = Tm = x * 4 hours
Now we need to determine for what values of x is Tm > Tl
⇒ x * 4 > 4
⇒ x > 1
So for x > 1, Mary spends more time babysitting than Lucy does
B.(7.5, –3.5) and (7.5, 3.5)
C.(7.5, 1.2) and (7.5, 2.3)
D.(7.5, –3.5) and (7.5, 7)
The points between whom the distance is 3.5 units apart are (7.5, 1.2) and (7.5, -2.3).
Given is to find the points between whom the distance is 3.5 units apart.
Using the distance formula for the points (7.5, 1.2) and (7.5, -2.3), we get-
d² = (- 2.3 - 1.2)² + (7.5 - 7.5)²
d² = (3.5)²
d = 3.5 units
Therefore, the points between whom the distance is 3.5 units apart are (7.5, 1.2) and (7.5, -2.3).

Answer:
675.7 dollars
Step-by-step explanation:
1) 475.35 + 75.35 + 125 = 675.7
3 times 5 times 2.5 = $37.5
3 x 5 =15
15 x 2.5 =37.5
37.5 x 2 = 75 for both of them
I don't know if this is right or not, but that's how I would solve it!
