The Kendrick made a mistake in step 4 he did not multiply the term (7 - 2x) with -1, and he wrote 3x-7-2x=23 instead of 3x -7 +2x = 23
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Kendrick was given the equations:
Step 1: 4x+2y=14 ...(1)
3x-y=23 ...(2)
From the equation first:
Step 2: 2y = 14 - 4x
Step 3: y = 7 - 2x put this value in the second equation
Step 4: 3x - (7 - 2x) = 23
Step 5: 3x -7 +2x = 23
Kendrick did a mistake in step 4 he did not multiply the term (7 - 2x) with -1
Thus, the Kendrick made a mistake in step 4 he did not multiply the term (7 - 2x) with -1, and he wrote 3x-7-2x=23 instead of 3x -7 +2x = 23

Answer:
1.63 Kilograms
Step-by-step explanation:
I started by finding out what the roast beef weighed. Then I added 740, 520, and 370 (what the roast beef weighs). I can work that way because they are all in grams. The total off all that equals 1630 grams. Then I converted that to kilograms. Which will end up giving you 1.63 kilograms.
Well, the formula for circumference is:
We already know that
, and that
(Approximately), so we have everything we need.
Substitute:
The circumference of the bicycle wheel is approximately 75.36 inches.
Hope this helped!

Answer:
Step-by-step explanation:
The inverse of can be calculated by swapping x and y and solving for y:
which corresponds to the third choice.
Answer:
B) 480
Step-by-step explanation:
The given is a regular hexagon so all interior angles are equal to each other their to find the sum:
4*180 = 720 to find the sum of <p+<q+<r+<s we divide this result by 6 because the hexagon has 6 interior angles, then multiply the result by 4
720/6 = 120
<p+<q+<r+<s = 120*4
<p+<q+<r+<s = 480
