For future reference, here is how to solve negative exponents.

For example
3^-4
take the reciprocal of 3 (write 3 as a fraction, 3/1, and write it the other way, 1/3). Then, raise 1/3 to the power of whatever the original exponent was, minus the negative, 4.
So
3^-4 = (1/3)^4 = 1/81 or 0.012345678901234567890123...

Is 7 + square root of 5 equal to square root of 5 plus a number, what do you know about the number? Why?
storchak [24]
The statement is true. The number is seven. I can find this through the commutative property of addition or plugging in the number and reversing the equation.

Key: a is 7, b is square root of five, c is solution, ? is what we're finding

Commutative: a + b = b + a

Plugging and Reversing: a + ? = c, c - a = b

At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawals,
denis-greek [22]

At the bank, Derek made 7 withdrawals, each in the same amount. His brother, John, made 5 withdrawls, each in the same amount.

Let x be  the amount of one of Derek's withdrawals

Each of John's withdrawals was $5 more than each withdrawal that Derek made.

x + 5 is t the amount of one of John's withdrawals

Derek made 7 withdrawals

So amount withdraw 7 times = 7x

John made 5 withdrawals

So amount withdraw 5 times = 5(x+5)

Both Derek and John withdrew the same amount of money in the end

(A)7x = 5(x+5)

(B) Solve for x

7x = 5x + 25

Subtract 5x from both sides

2x = 25

Divide by 2

x = 12.5

(C) check your solution

we plug in 12.5 for x in 7x= 5x + 25

7(12.5) = 5(12.5) + 25

87.5 = 62.5+ 25

87.5 = 87.5

(D) Each brother withdrawal 87.5 dollars
