b + b^3 = b^4

Find the value of x that makes this statement true

Brrunno [24]

$\frac{(-2)^{5x-3}}{(-2)^{2x}} =(-2)^{21}$

$(-2)^{5x-3-2x}=(-2)^{21}$ (The numerator and the denominator has same bases, therefore the powers will get subtracted. It is an exponential property)

$(-2)^{3x-3}=(-2)^{21}$

$3x-3=21$ (As the left hand side is equal to right hand side and the bases are on both the sides are equal too, we will equate their exponential power. Another property)

$x-1=7$

$x=8$ (After simplifying more, you'll get this)

Daniel has a coupon for $1.44 off

Art [367]

Answer:

Daniel will save $1.18

Step-by-step explanation:

First, find the cost of the name-brand flour with the coupon:

Subtract 1.44 from the original price of 9.12:

9.12 - 1.44

= 7.68

So, the price of the name-brand flour with the coupon is $7.68

Now, find how much he will save by finding the difference between this price and the price of the store brand flour:

8.86 - 7.68

= 1.18

So, Daniel will save $1.18

Answer:

3 hours or 180 minutes

Step-by-step explanation:
