If you compare table values to answer choices, you can see right away that several don't work. The number of centimeters is greater than the number of inches, so adding to or multiplying the number of centimeters by some number more than 1 will not give you the smalller number that is inches.
While it may work for the first number (5 inches) to add 7.7 to get the first number of centimeters (12.7), you have to know that you can only add like to like. You can only add inches to inches (getting a result of inches), or centimeters to centimeters (getting a result of centimeters). From the point of view of the units involved, it is <em>nonsensical</em> to add a pure number to a number of inches and expect to get a number of centimeters.
So, we're down to the second choice:
- The number of inches is multiplied by 2.54 to find the number of centimeters.
_____
To find the pattern in the table, you can ...
- observe that the inch values differ by 1
- observe that the centimeter values differ by 2.54
- realize that the constant differences mean the relation between inches and centimeters is linear, and that a change in an inch value of 1 inch is multiplied by 2.54 to find the corresponding change in centimeter value.

Answer:
Step-by-step explanation:
The plan 1 cost for x rides will be ...
y = 6 + 3.50x
The plan 2 cost for x rides will be ...
y = 12 + 1.50x
These costs will be equal when ...
y = y
6 + 3.50x = 12 + 1.50x . . . . . substitute for y
2.00x = 6 . . . . . . . . . . . . . subtract 6+1.50x
x = 3 . . . . . . . . . . . . . . . divide by 2
For 3 rides, the cost will be the same.
__
For 3 rides the cost is ...
y = 6 + 3.50(3) = 6 + 10.50 = 16.50
The cost for 3 rides will be $16.50 for either plan.
<u>Answer-</u>
An angle is labeled with either one capital letter or three capital letters
<u>Solution-</u>
<em>Point-</em>
As a point is 0 dimensional, so you just need 1 point to define a point.
<em>Line- </em>
As a line is 1 dimensional,so you need 2 points to define a line.
<em>Plane-</em>
A plane is 2 0r 3 dimensional, so you need 3 points to define a plane.
<em>Angle-</em>
An angle measures the amount of turn. An angles is labeled with a single letter at the vertex, as long as it is perfectly clear that there is only one angle at this vertex. Otherwise, it is named according to the intersecting lines with 3 letters.
This equals to 2/(1/5)+(1/5)/2.
=2 x 5+1/5 x 1/2
=10+1/10
=10 1/10 <---- This is mixed fraction, since you didn't want decimals.
Answer:
Step-by-step explanation:
6x + 3y = -18
Taking 3 common from left side
so, 3(2x+y) = -18
2x+y = -18/3
2x+y = -6 (equation 1)
and, 7x + 7y = 0
Taking 7 as commom from left side
7(x + y) = 0
x + y = 0/7
x + y = 0 (equation 2)
now , by using elimination method
subtracting equation2 from equation1
2x + y - (x + y)= -6 - 0
2x + y - x - y = -6
x = -6
so, x = -6
substituting value of x in equation 1
2(-6) + y = -6
-12 + y = -6
y = -6 +12
y = 6
hence, the value of x = -6
and value of y = 6
