Answer:
Cost of one glove pair is $ 8.50 and the cost of one hat is $6.50
Step-by-step explanation:
Let g represents the cost of one gloves pair
h represents the cost of one hat
Then
Cody brought two pairs of gloves and four hats for $43.00
This can be written as
2g + 4h = 43-------------------(1)
Tori bought two pairs of gloves and two hats for 30.00
This can be written as
2g + 2h = 30------------------(2)
Subtracting (2) from (1)
2g + 4h = 43
2g + 2h = 30
(-)
--------------------------
0g + 2h = 13
------------------------------------
2h =13
h = 13 / 2
h = 6.5---------------------(3)
Substituting (3) in (2)
2g + 2(6.5) = 30
2g + 13 = 30
2g = 17
g = 17 / 2
g = 8.5
So one hat is $6.50 and one pair of gloves is $8.50.
Answer: y = 9
Step-by-step explanation:
Since two points are given , we will use the formula for finding the equation in two points form , which is
= ![\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
= 1
= -3
= -9
= -9
Substituting into the formula , we have
= ![\frac{-9-(-9)}{-3-1}](https://tex.z-dn.net/?f=%5Cfrac%7B-9-%28-9%29%7D%7B-3-1%7D)
= ![\frac{-9+9}{-3-1}](https://tex.z-dn.net/?f=%5Cfrac%7B-9%2B9%7D%7B-3-1%7D)
= ![\frac{0}{-4}](https://tex.z-dn.net/?f=%5Cfrac%7B0%7D%7B-4%7D)
= 0
y + 9 = 0
y = 9
Answer:
6
Step-by-step explanation:
Let x = number of hours.
Let y = cost.
The fixed cost is $11.
The cost per hour is $2.
For x hours, the cost per hour is 2x.
y = 2x + 11
23 = 2x + 11
12 = 2x
x = 6

Answer: 29 d + 39
Step-by-step explanation:
Given : The deli sold, 13d+25 of the Turkey Waldorf Wraps and 16d+14 of the Triple-Decker Chicken Wraps.
Then, the total amount of wraps sold will be
13d+25 + 16d+14
Simplify
13d+16d+25+14 [add like terms]
= 29 d + 39
Hence, the polynomial expression that represents the total amount of wraps sold is 29 d + 39.
