Answer:
1.78 lb
Step-by-step explanation:
Total meat needed = 10 lb
David picks out 3 packages at the supermarket.
Each package weighs
2.73 lb
3.2 lb
2.29 lb
Total weight of the 3 packages = 2.73 lb + 3.2 lb + 2.29 lb
= 8.22 lb
How much more meat does David need?
Amount of meat David needs more = Total meat needed - Total weight of meat picked at the supermarket
= 10 lb - 8.22 lb
= 1.78 lb
David needs 1.78 lb more of meat to complete the total 10 lb meat needed
So,
4x + 1 = 5 + 2(2x - 4)
4x + 1 = 5 + 4x - 8
4x + 1 = 4x - 3
1 = -3 FALSE
There are ZERO solutions to this equation.
S = { }

Answer:
Area 108cm2
Step-by-step explanation:
triangle =<em>1</em><em>/</em><em>2</em><em> </em><em>×</em><em>base</em><em>×</em><em> </em><em>height</em><em> </em>
rectangle =<em>length</em><em> </em><em>×</em><em> </em><em>width</em>
<em>then</em><em> </em><em>add</em><em> </em><em>the</em><em> </em><em>area</em><em> </em><em>of</em><em> </em><em>each</em><em> </em><em>shape</em>
Equation can be used to find x is 60/55 + 60+x = 2.75
The time of going to rink is 2.75
We know,
speed = distance/time
⇒ Time = distance / speed
<h3>How to solve?</h3>
(1) Way to rink
Given :
Distance = 60 miles
Speed = 55 miles per hours,
⇒ Time taken by him = Distance / speed = 60/55 hours
(2) Way to home
Given : Distance = 60 miles
Let Speed be x,
⇒ Time taken by him = distance/speed = 60/x hours
Total time taken = 60/55 + 60+x
According to Question, Total time = 2.75 hours,
Thus, 60/55 + 60+x = 2.75 is the required equation.
