2(6y − 3) = 20 + 6y
Use the distributive property, which states a(b - c) = ab - ac
We should get:
2*6y - 2*3 = 20 + 6y
Which can be simplified to:
12y - 6 = 20 + 6y
That means the mistake was in step 2. The student didn't multiply the numbers and instead added the numbers.
Your answer is: <span>Step 2: 12y-6=20+6y</span>
I find the easiest way to do this type of ratio is doing TOTAL PARTS.
Answer:
Step-by-step explanation:
The missing details are:
--- Midpoint of ST
Required
Determine the coordinates of S
To do this, we apply the mid-point formula:
Where
The equation becomes:
Multiply through by 2
By comparison:
Hence, the coordinates of S is:
C. Revising because it should be your last stage in the writing process before you publish
He gets 1.13 times as many villagers for each town. Multiply the number of towns by 1.13:
17 towns x 1.13 = 19.21 villagers Round to 20
For an equation to solve for the number of villagers for any amount of towns, let the number of towns equal X, then multiply 1.13 by x:
Total villagers = 1.13x
