Answer:
Teo is 11 years old and Richard is 26 years old.
Step-by-step explanation:
Let R be the age of Richard and T be the age of Teo.
<u><em>First set up the equations:</em></u>
The combined age of Teo and Richard is 37:
R+T=37
Richard is four years old than twice Teo's age:
R=2T+4
<u><em>Then, solve the equations:</em></u>
Substitute (2) to (1) and solve for T:
(2T+4)+T=37
3T=11
T=11
Solve for R using (2):
R=2(11)+4
R=22+4
R=26
Answer:
The equation would be y = 3/2x - 1
Step-by-step explanation:
To find the answer in slope-intercept form, simply solve for y.
4x-4y/2=x+2 ----> Subtract 4x from both sides
-4y/2=-3x+2 ----> Multiply both sides by 2
-4y = -6x + 4 -----> Divide by -4
y = 3/2x - 1
You would recieve $37.95 a year then multiply that by 7 years to get $265.65
Answer:
Perimeter = 42 units Area = 57.73 square units
Step-by-step explanation:
Perimeter of an Astroid = 6l ---> 6 x 7 = 42 units
Area of an Astroid = (3 x pi x a^2)/8 = 57.73 square units
The answer is 1, good luck
