The cost of a bag of chips in a vending machine is $0.85. The cost of a Gatorade in the same machine is $1.50. Kennedy spent $23

.70 on chips and Gatorade for her track team, and bought a combination of 21 bag of chips and Gatorade. Which step shows the FIRST mistake in applying the Elimination Method to solve this problem? A) Step1: - 0.85(x + y = 21) 0.85x + 1.50y = 23.70 B) Step 2: - 0.85x + y = 21 0.85x + 1.50y = 23.70 C) Step 3: 2.50y = 44.70 D) Step 4: y = 17.88

A bag of chip  = 0.85, let a bag of chip be x
a bag of gatorade is 1.50, let gatorade be y
23.70 is the amount Kennedy spent in all

0.85x + 1.50y = 23.70
step 1: shows the wrong step already, because you shouldn't take out a -0.85, and y is not 0.85 either, but 1.50, so y should still have 1.76 left

so your answer should be step 1.

hope this helps

Step 1 : -0.85(x + y = 21) <== I have no idea why they r  multiplying -0.85 by that equation

it should be :
x + y = 21
0.85x + 1.50y = 23.70

How many triangles can be formed with segments measuring 4. 72 yd, 6. 31 yd, and 1. 67 yd? none one more than one.
scoray [572]

The triangle inequality theorem is not followed,  no triangle can be formed.

<h3>Triangles</h3>

In Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.

The triangle inequality theorem describes the relationship between the three sides of a triangle.

According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.

Here, the sides are 4.72 yds, 6.31 yds, and 1.67 yds.

4.72 + 6.31 = 11.02  >  1.67  (theorem followed)

4.72 + 1.67 = 6.39  > 6.31    (theorem followed)

6.31 + 1.67 = 7.98 > 4.72 (theorem not followed)

Since the triangle inequality theorem is not followed,

Hence, no triangle can be formed.
