What is (3xy^2)(-6xy^4)

krok68 [10]

Answer:

$-18x^2y^6$

Step-by-step explanation:

we have

$(3xy^2)(-6xy^4)$

Applying property of exponents

$x^{m} x^{n}=x^{m+n}$

$(3xy^2)(-6xy^4)=(3)(-6)(x^{1+1})(y^{2+4})=(-18)(x^{2})(y^{6})=-18x^2y^6$

Liam is saving up for a new cell phone. He uses the equation P= I + HB, where P is the cost

Stels [109]

Answer:

$H=\dfrac{P-I}{B}$

Step-by-step explanation:

Given the expression: P= I + HB

Where:

P = cost of the phone Liam is saving for.
I = amount of money he started with.
H = number of hours he babysits
B = hourly rate for babysitting.

We want to find an expression for H, the number of hours Liam will need to babysit to save enough money for a cell phone.

Our goal is to isolate the variable H in the expression P= I + HB.

P= I + HB

Subtract I from both sides

P-I=I-I+HB

HB=P-I

Divide both sides by B

$\dfrac{HB}{B} =\dfrac{P-I}{B}\\\\$Therefore\\\\H=\dfrac{P-I}{B}$

Well if she has 2 whole watermelons and 1/3 of one that would be 2 1/3 and that would be the mixed number and for the inproper fraction it would be 1 4/3 because you want to take out 1 from the 2 1/3 and add it on to the 1 of the 1/3 making it 1 and 4/3 I hope this helps!
