Length in units:
Use phytogoras theorem or measure it by a ruler if your using a graph paper
AB = 5.65 units
AC = 5.83 units
CB = 1.41 units
Perimeter =5.65 + 5.83 + 1.41 = 12.89 units
Area = 1/2 * 1.41 * 5.65 = 3.98units
Answer:
x > 2
Step-by-step explanation:
Given
- 8x + 2x - 16 < - 5x + 7x ← simplify both sides
- 6x - 16 < 2x ( subtract 2x from both sides )
- 8x - 16 < 0 ( add 16 to both sides )
- 8x < - 16 ( divide both sides by - 8 )
Remembering to reverse the symbol as a consequence of dividing by a negative value.
x > 2
You would put x over a hundred because you don't know what percent it is then you would put 180 over 240 because the other part of the prapotion is is over of. then you would cross multiply and get 7.5
<u>Answer-</u>
Set of constraints to model the problem are,

<u>Solution-</u>
Let us assume,
x = the number of lawns weeded by Gwen,
y = the number of dogs walked by Fabio.
Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog,

They need at least $510 to purchase the new gaming station, means they need $510 or more than $510.
An equation for this situation will be,

The number of dog walked by Fabio has scheduled is no more than twice the number of yards Gwen has scheduled to weed, means y must be less than or equal to 2x.
An equation for this situation will be,

Fabio will walk at least 25 dogs, means y must be greater than of equal to 25.
An equation for this situation will be,

7% of $45:
= 0.07 * 45
= 3.15
Increase = $3.15
