Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
The original amount of money on the gift card was $45. After buying 8 cups of coffee, the remaining balance was $25.
<u>First, we need to calculate the unitary value of each cup of coffee:</u>
Unitary cost= 20/8= $2.5
<u>Now, we can structure the remaining balance formula (A):</u>
A= 45 - 2.5x
x= cup of coffee
<u>After 2 cups:</u>
A= 45 - 2.5*2
A= 40
Each triangle has a side length of 1, which is why the perimeter of the single triangle is 3. We just add up the three sides (1+1+1 = 3).
Similarly, the perimeter of the second figure is 4 because we have 4 sides that are same length which add up to 4 total (1+1+1+1 = 4).
Pattern #3 has a perimeter of 5 because the bottom length is 2 units long, the top length is 1 unit long, and each diagonal is 1 unit long. So we have 5 total.
The perimeters so far are: 3, 4, 5
Each time we are adding 1 to the old perimeter to get the new perimeter. So pattern #4 will have a perimeter of 6. Sure enough, if you count the sides out, then you should get 6 total.
Note: only count out the exterior sides. Do not count the interior sides.
--------------------------------------------------------------------
x = number of triangles, y = perimeter
If x = 1, then y = 3
If x = 2, then y = 4
if x = 3, then y = 5
If x = 4, then y = 6
Whatever x is, we add on 2 to get the value of y.
So the equation is therefore y = x+2. If you want, you can use the slope formula to find the value of m. Then use it to find the value of b, so you determine that y = mx+b turns into y = 1x+2 which is the same as y = x+2
Answer: y = x+2
ok so you are given 61degrees and you want to find b you can ignore that weird line on the top left because its not needed but
you can see that 61degrees is next to b and they are on a strait line so that means that they have to equal to 180
so 61 + b = 180
b = 119
so b should equal 119
Answer:
42 < x < 57
Step-by-step explanation:
If you want to show an inequality showing a limit then you would have to use < to model it the inequality would be 42 < x < 57
