Step-by-step explanation:

Monthly bill - Flat rate = $38.44 - $3.99 = $34.45.

Minutes used = $34.45 / $0.05 = 689.

Explain how multiplying playing with 6 is like multiplying with 3

mote1985 [20]

6 is only the double of 3
3×2=6

Any number that's multiplied by 6 will be the double of any number multiplied by 3, or vice versa, any number multiplied by 3 will be half of any number multiplied by 6. This is because 6 is a multiple of 3.

Take for example:
850×6=5100 ⇔ 850×(3×2)=5100

Let f(x)=2x^2+7x-5 and g(x)=-8x^2-3x+5 what is g(x)+f(x)

ser-zykov [4K]

F(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5
g(x) + f(x) = -8x² - 3x + 5 + 2x² + 7x - 5 = - 6x² + 4x

Answer: -6x² + 4x

Geri believed the answer to one of her homework problems was 2 cubed. After checking her work, she realized the correct answer w

TiliK225 [7]

Answer:

The correct answer is 64 times Geri’s original answer

Step-by-step explanation:

Given

Gari's Answer: 2³

Correct Answer: 2⁹

Required:

Relationship between both answers

Let Gari's answer be represented by G and the Correct answer be represented by C; Such that

G = 2³

C = 2⁹

Divide C by G

$\frac{C}{G} = \frac{2^9}{2^3}$

From law of indices, $\frac{a^m}{a^n} = a^{m-n}$

Applying this law, we have

$\frac{C}{G} = 2^{9-3}$

$\frac{C}{G} = 2^{6}$

$\frac{C}{G} = 2*2*2*2*2*2$

$\frac{C}{G} = 64$

Multiply both sides by G

$G * \frac{C}{G} = 64 * G$

$C = 64G$

Hence, we can conclude that the correct answer is 64 times Geri’s original answer
