Choice C !! Hope this helps
The equation is 76*120/3.
76*120/3
9,120/3
3,040
The car will travel 3,040 yards in 120 seconds at that speed.
Answer:
option 1 and 4
Step-by-step explanation:
The elimination method should be used when there are two variables with the same number in front of them but different signs.
In the first system, the first equation has -8y while the second one has 8y.
Both equations have an 8y with different signs therefore using the elimination method would be most logical.
In the fourth system, the first equation has a -4x while the second one has 4x.
Both equations have 4x with different signs therefore using the elimination method would be most logical
Reasons it can't be the other options :
In the second system, no variable has the same number before it so no variable can be eliminated unless you multiply the equations by a common multiple. The best method for this system would be graphing
In the third system y is defined by an expression therefore using the substitution method is the most logical approach.
The sum of the interior angles of the polygon shown is 540 degrees
<em><u>Solution:</u></em>
<em><u>The sum of the measures of the interior angles of a polygon with n sides is:</u></em>
From given figure in question,
Number of sides in polygon = 5 ( which is a pentagon )
Therefore,
n = 5
<em><u>Thus the sum of measures of interior angles is:</u></em>
Thus the sum of the interior angles of the polygon shown is 540 degrees
Answer:
x=6 square root 3 y=9
Step-by-step explanation:
x= 3 square root 3 * 2
y=3 square root 3 times square root 3
