Random question so I can keep studying.. Find the value of x when 2x = 64
2 answers:
Answer:
x=32
Step-by-step explanation:
Our goal when solving algebraic equations is always to isolate the variable. We can do this by performing reverse operations (for example, the reverse operation of addition is subtraction and the reverse operation of multiplication is division) on both sides of the equation.
Because x is being multiplied by 2, <em>divide</em> both sides by 2 to isolate x.
2 cancels out on the left side of the equation
I hope this helps!

Answer:
The difference in the amount of interest she would have to pay for the two loans is $1,400
Step-by-step explanation:
The amount of loan Holly is taking out, P = $10,000
The choices available for the loan are;
1) Loan duration, T₁ = 4-year
Interest rate, R₁ = 4%
2) Loan duration, T₂ = 6-year
Interest rate, R₂ = 5%
For the first choice, we have;
The simple interest, I, given by the formula;
For the second choice, we have;
The simple interest, I, given by the formula;
The difference, D, in the amount of interest she would have to pay for the two loans is therefore;
D = I₂ - I₁ = $3,000 - $1,600 = $1,400
The difference in the amount of interest she would have to pay for the two loans = D = $1,400.
