Answer:
Step-by-step explanation:
0.00048*.81=0.0003888
0.0003888*10=0.003888
0.003888*(10)=0.3888
0.3888-7=-6.6112
-6.6112*0.027=-224.8592593
-224.8592593*0.04= -9.794370372
-9.794370372*(10)=-97.94370372
-97.94370372*6= -587.6622223
Answer:Jason is 5 years old.
John is 4 years old.
Jackson is 12 years old.
Step-by-step explanation:
Let x represent the age of Jason.
Let y represent the age of John.
Let z represent the age of Jackson.
The ages of three siblings Jason John and Jackson totals 21 years. It means that
x + y + z = 21 - - - - - - - - - - -1
Jason is one year older than John. It means that
x = y + 1
Jackson is three times as old as John. It means that
z = 3y
Substituting x = y + 1 and z = 3y into equation 1, it becomes
y + 1 + y + 3y = 21
5y = 21 - 1 = 20
y = 20/5 = 4
x = y + 1 = 4 + 1
x = 5
z = 3y = 3 × 4
z = 12

Answer:
(x-4)*2 + (y-2)*2 = 25
Step-by-step explanation:
(x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.
h = 4
k = 2
r = 5
sub in all this info:
(x-4)*2 + (y-2)*2 = 25
