<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:
7707 tickets
Step-by-step explanation:
From the question we know that:
the number of tickets sold at the counter on
First day = 1094 tickets
Second day = 1812 tickets
Third day = 2050 tickets
Fourth day = 2751 tickets
The total number of tickets sold on all the four days is calculated as:
(1094 + 1812 + 2050 + 2751)tickets
= 7707 tickets
