Help umAshley solved the equation for m using the following steps. -4.5 + m = 17

-4.5 -4.5

m = 12.5

What was Ashley’s error?
Ashley should have subtracted 17 to both sides.
Ashley should have added 4.5 to both sides.
Ashley should have added 17 to both sides.
Ashley’s work does not have an error.

Ashley should have added 4.5 to both sides.

Step-by-step explanation:

since 4.5 is negative she should have added 4.5 to cancel them out

hope this helps

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

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!
