Answer:
C. 2x - 3(-3x - 4) = -21.
Step-by-step explanation:
y + 3x = -4
2x - 3y = -21
From the first equation y = -3x - 4.
Substituting this for y in the second equation, we have:
2x - 3(-3x - 4) = -21.

Answer:
I = $ 120.00
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 2000 × 0.03 × 2 = 120
I = $ 120.00
The simple interest accumulated
on a principal of $ 2,000.00
at a rate of 3% per year
for 2 years is $ 120.00.
Answer:
x = 2.4
Step-by-step explanation:
Simplify.
24 - 4x + 4 = 6x + 2 - 6
Combine like terms (24 + 4 = 28, sorry for the confusion!)
28 - 4x = 6x - 4
Add x and add 4 to both sides.
10x = 32
x = 3.2
Answer:
40 its the correct answer
