<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:
you will add the numerator and the denominator and or you look for lowest common factor
Answer:
1250
Step-by-step explanation:
x^3*y^1
Let x = 5 and y = 10
5^3* 10^1
PEMDAS says powers first
125 * 10
Then multiply
1250
Answer:
Ed has traveled for 3 hours and 17 minutes, and has 2 hours and 28 minutes left to travel.
Step-by-step explanation:
Given that Ed is on a road trip and he has already traveled 201 miles and is driving at a rate of 61 mph, the equation could be used to find how many hours he has traveled and how many and has left in his road trip traveling 697 total miles is the next:
201/61 = 3.29
100 = 60
29 = X
29 x 60/100 = X
29 x 0.6 = X
17.4 = X
So, Ed has traveled for 3 hours and 17 minutes.
697 - 201 = 496
496/201 = 2.46
100 = 60
46 = 0
46 x 0.6 = X
27.6 = X
Thus, he has 2 hours and 28 minutes to travel.
