Answer:
a = 12 years
Step-by-step explanation:
Mark is 6 years older than his brother Sam. Now, we are asked to represent Sam’s age by a. This means that if Sam is a years old, Mark is (a + 6) years old.
The sum of their ages is 30, this means that when we add their ages together, we get the sum of thirty.
Mathematically this means a + a + 6 = 30
2a + 6 = 30
This is the equation needed to get a. To get a , we proceed to solve the equation to completion.
2a = 30 - 6
2a = 24
a = 24/2
a = 12
The two values are positive 9 and negative 9
Answer:
1. (0,0)
2. 2
Step-by-step explanation:
The origin is the middle or the center which is (0,0)
another way to write 0.5 is 1/2 but be careful because it said reciprocal which means you need to flip it over which is 2
Hope this helps!
X * Y * 9 = 432
Divide 9 from both sides
X * Y = 48
That gives you a variety of answers
1 * 48
2 * 24
4 * 12
6 * 8
