1. One more than three times a number is 7,

in number equations

The answer is 2

Step-by-step explanation:

2x3=6 +1 =7

answer is : 2

Step-by-step explanation:

2x3=6+1=7

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
