Enter the value of n so that the expression (−y+5.3)+(7.2y−9) is equivalent to (6.2y+n) .

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

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.
