Answer:
The age of each person is:
- Jess is <u>21</u> years old.
- Mac is <u>66</u> years old.
Step-by-step explanation:
To solve this problem you must make two equations. First, we name Jess and Mac as variables:
j = Jess age.
m = Mac age.
Now we make the equations, the first equation has the information "Jess is 12 years less than half as old as Mac":
1.
The second equation has the information "The sum of their age is 87":
2.
Now, we replace the first equation in the second one:
And we operate:
We clear the variable m:
How we know Mac's age is 66 years old, we can identify Jess' age with the second equation:
We replace the value of m:
And clear the variable j:
In the end, Jess's age is 21 years old.

Step-by-step explanation:
Connor score is 25% more than Max's score so for the equation you need to find what 25 percent of that answer is and then add it to Maxs score to find the total.
Answer:
Some possible values are -5, -3, -2.
Step-by-step explanation:
Basically if d(discriminant)
d > 0 = 2 x intercepts,
d = 0 means one x intercept
d < 0 = 0 x intercepts
:) Hoped this helped :)
They are congruent angles
