Every whole number is a rational number because whole numbers can be written as fractions.
4x + 25 + x - 15
5x + 10
/ 5 / 5
x = 2

Answer:
<em>Interest = $3,888</em>
Step-by-step explanation:
Formula:
I = prt or I = p · r · t
what it stands for:
I = amount of interest
P = principal amount ($1,200)
R = interest rate (in years)(3% into decimal which would be .03)
T = amount of time (in years)($108)
so:
I = prt
I = (1,200)(.03)(108)
I = $3,888
Interest = $3,888
Answer:
y = -1/3x - 5
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes, so the line is:
y = -1/3x + b
Finding the value of b, using the given point (-9, -2)
-2 = -1/3*(-9) + b
-2 = 3 + b
b = -2 - 3
b = -5
The line is
y = -1/3x - 5

Answer:
c
Step-by-step explanation:
C. BD= 20
Use similar triangles to write a proportion and then cross multiply to solve.
AE: AC = AD:AB
(ONCE YOU KNOW AB YOU CAN SUBTRACT AD FROM AB TO GET BD =20)
So, 15:40 = 12: AB=32. now 32-12 = 20 so BD = 20
