Finish this please : 3x + 15 = 2x + 10 + x + 5 (the equation)

3x + 15 = ?x + ?

3x - ? + 15 = 3x - ? + 15

? = ?

The question marks are the ones you have to fill out.

Step-by-step explanation:

3x+15=2x+10+x+5

Step 1: first thing ur gonna want to do is combine like terms. X can also be written as 1x.

3x+15=3x+15

Step 2: use subtraction property of equality to even out the equation

3x-15+15=3x-15+15

3x=3x

Step 3: Divide by 3 on each side

X=X

The answer is infinitive

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
