Answer:
A= 15 root 5 - 10 ÷ 41
Multiply (3 root 5 - 2) top and bottom. Simplify
B= - 2
Multiply (root 3 + root 5) top and bottom. Simplify
C= 6x - 3 root xy ÷ 4x - y
or
3x - 3 root xy ÷ 2x - y
(because 6 & 4 is Divisible by 2)
Multiply (2 root x - root y) top and bottom. Simplify
Root means a square root - so, replace the word root with a square root!
Hope this helps!
Answer:
Son's age is 14 and father's age is 38
Step-by-step explanation:
The question in English is
Ten years ago my son's age was 1\7 of the father's. Now his ages add up to 52. What is the son's age?
Let
x -----> son's age
y ----> father's age
we know that
------> equation A
-----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (14,38)
see the attached figure
therefore
son's age is 14 and father's age is 38
The answer to this problem is 5 units^2
Let the two numbers be x and y.
The difference between the numbers is 4. Therefore
x - y = 4 (1)
The sum of one-half of each number is 18, therefore
x/2 + y/ 2 = 18
x + y = 36 (2)
Add equations (1) and (2).
(x - y) + (x + y) = 4 + 36
2x = 40
x = 20
From (2), obtain
y = 36 - x = 36 - 20 = 16.
Answer: The two numbers are 16 and 20.
Answer:
1.5 MPH
Step-by-step explanation:
