X=25 is the answer
EXPLANATION:
Since we have here similar triangles, then 2x+2/x+3 must be equivalent of 26/14
2x+2/x+3=26/14
2x+2/x+3=13/7
7(2x+2)=13(x+3)
14x+14=13x+39
x=25
Answer: Sheldon babysat for 6 hours on Saturday.
Step-by-step explanation:
Let x represent the number of hours that Sheldon babysat on Saturday.
He babysat for Saturday and Sunday. If Sheldon babysat for 8 hours on Sunday, it means that the total number of hours that he babysat during the weekend was
(8 + x) hours.
Seldon gets paid $4 per hour to baby sit his cousins. It means that the total amount that he earned during the weekend was 4(8 + x)
He made a total of $56. Therefore,
4(8 + x) = 56
8 + x = 56/4 = 14
x = 14 - 8
x = 6 hours
Same Denominator We Add The Numerators:
Answer:
This is an upwards-opening parabola with a vertex of (2, 0). That +2 moves the vertex up 2 along the y axis. If this is a positive parabola, which it is, then the vertex is a minimum.
(10-4)/(7-5)=6/2=3.
The slope of the line that passes through those two points is 3.
