How to Evaluate Algebra Expressions?
We are given that;
x = -2
y = -3
z = 5
A) The algebraic equation 2x + 3y + z gives;
2(-2) + 3(-3) + 5 = -5
B) x - y gives;
-2 - (-3) = 1
C) 2(x + y)/z gives;
2(-2 - 3)/5 = -2
D) 3x² - 2x + 1
f(-2) = 3(-2)² - 2x + 1
f(-2) = 17
E) 3y(x + x² - y)
3(-3)(-2 + (-2)² - (-3))
-9 * 5 = -45
F) -z²(1 - 2x)/(y - x)
Thus;
-5²(1 - 2(-2))/(-3 - (-2))
= 625

Answer:
<h3>81.</h3>
Step-by-step explanation:
**Whenever you see a variable and a coefficient together, multiply them.**
Rose = <span>$2,600 x 0.041 x 9 = $959.40
Total = $2,600 + 959.40 = $3,559.40
</span>Dennis = <span>$2,200 x 0.057 x 9 = $1,128.60
Total = $2,200 + $1,128.60 = $3,328.60
</span>$3,559.40 - $3,328.60 = $230.80
<span>Answer
Rose has greater total amount of money than Dennis.
It's $230.80 greater than Dennis.
