Jake will be represented by variable a.
John will be represented by variable o.
a=o+10
a+5= 2(o+5)
For the second equations, write a literal equation to solve for a.
a+5=2o+10
a=2o+5
Since we have two expressions that equal a, we can tell that the two expressions are equal.
o+10= 2o+5
10=o+5
5=o
We now have the age of John. Plug his age in to find Jake's age.
a=5+10
a=15
Final answer: Jake is 15
Answer:
area = 16 cm²
Step-by-step explanation:
area of rectangle = 3x4 = 12
area of triangle = 2x4x0.5 = 4
12 + 4 = 16 cm²
another way is :
1/2(b1+b2)(h) = area
1/2(3+5)(4) = 16 cm²

To find the domain and range is very simple. The domain will always be the input values or x values. For example ( 3,0) the domain is 3 being the x value. The range is the output value or y value and in the example (3,0) the range is 0. Hope this helps :)
