Which of the following is equivalent to log7 50 rounded to three decimal places? 2.010 1.772 0.854 0.497

Option A -              

Step-by-step explanation:

Given : The expression

To find : Which of the following is equivalent and rounded to three decimal places.

Solution :

We solve the given expression   using calculator

We get,

Rounded to three decimal places

Therefore, Option A is correct.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

b) well because you get well
