Answer:
V = 3
Step-by-step explanation:
<u><em>Given:</em></u>
<em>Perimeter of the pentagon is 52 units.</em>
<em>Solve for value of v.</em>
<u>Solve:</u>
<em>Let first put it into a equation base on the given;</em>
<em>6v + 8 + 8 + 3v + 1 + v + 5 = 52</em>
<em>Add the numbers</em>
<em>6v + 22 + 3v + v = 52</em>
<em>Combine like terms</em>
<em>10v + 22 = 52</em>
<em>Subtract 22 from both sides</em>
<em>10v + 22 - 22 = 52 - 22</em>
<em>Simplify</em>
<em>10v = 30</em>
<em>Divide both sides by 10</em>
<em>10v/10 = 30/10</em>
<em>Simplify</em>
<em>v = 3 </em>
<em>Check Answer:</em>
<em>6(3) + 8 + 8 + 3(3) + 1 + (3) + 5 </em>
<em>18 + 8 + 8 + 3(3) + 1 + (3) + 5 </em>
<em>18 + 16 + 9 + 1 + 8</em>
<em>18 + 16 + 9 + 9</em>
<em>18 + 16 + 18</em>
<em>36 + 16</em>
<em>52</em>
<em>Hence, v = 3</em>

Answer:
$1.25
Step-by-step explanation:
This can best be determined using a set of linear equations that are solved simultaneously.
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations.
Let the cost of a cookie be c, cost of a doughnut be d and that of a box of doughnut hole be h then if cost of 4 cookies, 6 doughnuts, and 3 boxes of doughnut holes is $8.15, we have
4a + 6d + 3h = 8.15
and the cost of 2 cookies, 3 doughnuts, and 4 boxes of doughnuts holes is $7.20 then
2a + 3d + 4h = 7.20
Dividing the first by 2
2a + 3d + 1.5h = 4.075
subtracting from the second equation
2.5h = 3.125
h = 1.25
The cost of a box of doughnut holes is $1.25
Answer:
(- 2, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = - 1 → (1)
x + 4y = - 6 → (2)
Rearrange (2) expressing x in terms of y by subtracting 4y from both sides
x = - 6 - 4y → (3)
Substitute x = - 6 - 4y into (1)
2(- 6 - 4y) - 3y = - 1 ← distribute and simplify left side
- 12 - 8y - 3y = - 1
- 12 - 11y = - 1 ( add 12 to both sides )
- 11y = 11 ( divide both sides by - 11 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = - 6 - 4(- 1) = - 6 + 4 = - 2
Solution is (- 2, - 1 )
