Katie went shopping with her friends Erin. Katie bought 3 shirts and 2 pairs of pants for $80. Erin bought 3 shirts and 4 pairs
Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

shirt = x, pants: y

Katie equation: 3x + 2y = 80, Erin equation: 3x + 4y = 116  

3x + 2y = 80

3x = 80 - 2y

x = 80/3 - 2y/3

3(80/3 - 2y/3) + 4y = 116

80 - 2y + 4y = 116

80 + 2y + 116

2y = 36

y = 18, pants cost $18

3x + 4(18) = 116

3x + 72 = 116

3x = 44

x = 14.66... (66 is repeating), shirts cost $14.66

check work:

Katie: 3(14.66) + 2(18) = 79.98 which is roughly 80.

GIVING BRAINLIEST TO THE PERSON THAT CAN EXPLAIN THIS THE BEST (:
Vinvika [58]

Answer:

30

Step-by-step explanation:

Perimeter of parallelogram = 70 ft

-> 2x + 2y = 70 .....(1)

x = 6y (Given) .....(2)

From equations (1) & (2)

2(6y) + 2y = 70

12y + 2y = 70

14y = 70

y = 70/14

y = 5

-> x = 6*5

-> x =30

In ΔWXY, the measure of ∠Y=90°, YX = 40, XW = 41, and WY = 9. What ratio represents the cosine of ∠W?
Tju [1.3M]

Answer:

\cos{W} = \frac{9}{41}

Step-by-step explanation:

Cosine of an angle:

The cosine of an angle, in a right triangle, is the length of the side adjacent to this angle divided by the hypotenuse.

Length of the largest side:

The length of the largest side is 41, that is, the hypotenuse is 41. The hypotenuse is XW.

WY = 9.

This means that the length of the adjacent side to angle W is 9.

What ratio represents the cosine of ∠W?

Adjacent side has length 9, hypotenuse has length 41. So

\cos{W} = \frac{9}{41}
