Shana and Marie will update parts of their computer system. They will update the motherboard for $259.99, 2 USB
Furkat [3]

Answer:

<em>12.5w = 419.38</em>

<em>and</em>

<em>15.5w = 419.38</em>

Step-by-step explanation:

find the total cost of all the computer parts.

= 259.99 + 2* 39.95 + 79.49 = $419.38

Shana will save $12.50 per week and Marie will save $15.50

per week

therefore we can create two inequalities

<h2><u> Shana:</u></h2>

12.50 * w = 419.38

<em>12.5w = 419.38</em>

w = 419.38/12.5

w = 33.5504

<h2><u>Marie</u></h2>

15.50*w = 419.38

<em>15.5w = 419.38</em>

w = 419.38/15.5

w =27.0568

Evaluate the following expression [(15+1)/2-4]*6
Travka [436]

Based on the information given, the value of the equation will be -48.

From the information given, the expression is given as:

= (15+1)/2-4]*6

We'll solve the bracket first.

= (15+1)/2-4]*6

= (16 / 2 - 4) × 6

= (16/-2) × 6

= -8 × 6

= -48

In conclusion, the value of the equation will be -48.
