We have been given the steps to solve the equation as
Step 1: 2x = 18
Step 2: x = 18 − 2
Step 3: x = 16
There is an error in step 2.
We have
x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.
So we must divide both sides by 2.
Therefore, A is the correct option.
A) She did not divide 18 by 2.
249=249=203 first you part it up 249+249=498+203=701.
They both take 17.1 min to make the pizzas.
<u>Step-by-step explanation:</u>
Ron can do a job in 30 mins =
Jeff can do a job in 40 mins =
They both work together =
We have to take LCM of 30 and 40 as 120, so that the denominator becomes equal, also we can add them.
=
Further we get,
They both work for 17 .1 mins to make the same number of pizzas.
