Answer:

7 7/10

Step-by-step explanation:

rewrite it as a fraction of one

7.7/1

then you'll multiply both top and bottom by 10 (only for every number after the decimal pt.)

7.7/1 = 7.7(10)/1(10) that'll get you to77/10

then you just simplify 77/10 to 7 7/10

Part A: If (72)x = 1, what is the value of x? Explain your answer. (5 points)

vichka [17]

Answer:

see below

Step-by-step explanation:

Part A: (72)^x = 1

Take the log base 72 of each side

log72(72^x) = log 72(1)

We know log a^b = b log a

x log72(72) = log72(1)

x = log72(1)

x = 0

Part A: (70)^x = 1

Take the log base 70 of each side

log70(70^x) = log70(1)

We know log a^b = b log a

x log70(70) = log70(1)

x = log70(1)

x = 0

What is the value of x in the equation. 8 x - 2 y= 48 when y =4

goldfiish [28.3K]

$\qquad$ ❄️ $\boxed{\bf x = 7}\\\\$

We are given –

$\qquad$ $\twoheadrightarrow\bf 8x -2 y =48$

And also value of y's given. So, just put the value of y in the given equation.

___________________________________

$\qquad$ $\purple{\twoheadrightarrow\bf 8x -2 y =48}$

$\qquad$ $\twoheadrightarrow\sf 8x - \underbrace{2 \times 4} =48$

$\qquad$ $\twoheadrightarrow\sf 8x - 8 =48$

$\qquad$ $\twoheadrightarrow\sf 8x = 48 +8$

$\qquad$ $\twoheadrightarrow\sf 8x = 56$

$\qquad$ $\twoheadrightarrow\sf x =\cancel{\dfrac{56}{8}}$

$\qquad$ $\purple{\twoheadrightarrow\bf x= 7}$

Henceforth, value of x is 7.
