Step-by-step explanation:
Solving (a): The Variables
The variables are the ages of Jaime, Crystal and Marissa;
Let
x represents Jaime's age;
y represents Crystal's age;
z represents Marissa's age
Solving (b): Equation
Solving (c): Result of the equations
-- (1)
-- (2)
-- (3)
Make y the subject in (1)
Substitute and in (3)

Solve for x
Substitute in and
This implies that;
Jaime is 12; Crystal is 9 and Marissa is 24 years old
Solving (d): Essence of the question
The question asks that we solve for the ages of Jaime, Crystal and Marissa
Answer:
25 and 18
Step-by-step explanation:
To evaluate an expression, substitute the values x=6 and y=4 into each expression. Replace the x and y with these values then simplify.
9x - 29 ------> 9(6)-29 = 54 - 29 = 25
7y - 10 ------> 7(4) - 10 = 28 - 10 = 18
Look like that first one is supposed to have a denominator of 2.
This is a geometric series with a common ratio 4, so it diverges (absolute value 1 or more), meaning it has no sum. Choice C.
The sum of all 3 angles in a triangle is 180
180-44=136
And you know that angle A is over 90 degrees so I believe it is 100 leaving angle b to be 36
9514 1404 393
