<h3>Equation : x + y = 170 and y = 2x - 40</h3><h3>The weight of Bill is 70 pounds and weight of mark is 100 pounds</h3>
<em><u>Solution:</u></em>
Let the weight of Bill be "x"
Let the weight of mark be "y"
Given that,
Mark and Bill have a combined weight of 170 pounds
Therefore,
x + y = 170 ------- eqn 1
Mark weighs 40 pounds less than twice Bill's weight
y = 2x - 40 ------- eqn 2
<em><u>Substitute eqn 2 in eqn 1</u></em>
x + 2x - 40 = 170
3x = 170 + 40
3x = 210
x = 70
<em><u>Substitute x = 70 in eqn 2</u></em>
y = 2(70) - 40
y = 140 - 40
y = 100
Thus weight of Bill is 70 pounds and weight of mark is 100 pounds

Answer:
Step-by-step explanation:
Given:
Brett orders 2 meatball,1 turkey,1 veggie party-size sandwiches.
Each sandwich costs the same amount.
The total amount cost of the sandwiches, including tax, is $54.36.
Question asked:
What is the cost of each sandwich including tax?
Solution:
Let cost of each sandwich including tax = 
<u>Total number of sandwich = 2 + 1+ 1 = 4</u>
<u><em>As each sandwich costs the same amount and total amount of cost of 4 sandwiches, including tax, is $54.36, the equation will be:-</em></u>
By dividing both sides by 4,
Thus, the cost of each sandwich including tax is $13.59
