Answer:

w=3

Step-by-step explanation:

7 + 3x - 1 = w(x + 2)

Solve for w

Distribute

7 + 3x - 1 = wx + 2w

Combine like terms

3x+6 = wx+2w

For this to have infinite terms

3x = wx   and 6 = 2w

3x = wx

Divide by x

3 =w  

and 6 = 2w

Divide by 2

6/2 = 2w/2

3 =w

When w = 3, there will be infinitely many solutions

x = 5

I hope this helped :D

Average = ( 3 + 6 + 9) / 3 = 18 / 3 = 6

substitute for stuffed animals in eqn 2

45 + 15 = 60

Answer:

The girls worked together on their art project for 1 hour and 50 minutes.

Step-by-step explanation:

In order to find the answer you have to find the difference between the time they began working and the tine they finished working. You have to subtract 3:25 from 5:15.

Since 25 minutes on the time they began working is higher than 15 minutes, you have to subtract 1 from the time they finished working that is 5 hours:

5-1=4

Then, you have to increase the minutes on the time they finished working by 60:

15+60=75

Now, you have to subtract the minutes which would be 25 from 75:

75-25=50

Finally, you have to subtract the hours which would be 4 minus 3:

4-3=1

The result would be 1 hour and 50 minutes.

According to this, the answer is that the girls worked together on their art project for 1 hour and 50 minutes.

Step by step explanation:

The cost per ounce will be equal to $0.9.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a grocery store sells three sizes of bags of one brand of potato chips. The big bag is 14 ounces and costs $6.30. The medium bag is 9.75 ounces and costs $2.50. The small bag is 8 ounces and costs $2.48.

The cost per ounce for medium size bag is calculated as,

2.75 ounces = $2.5

1 ounce = 2.5 / 2.75

1 ounce = $0.9

50d^2 - 98e^2

Factor out 2.

2(25d^2 - 49e^2)

We now factor the difference of two perfect squares within the parentheses.

2(5d - 7e)(5d + 7e)

This is as far as we can factor.

Done!

The factor of the expression into an equivalent form 50d²- 98e² would be;  2(5d - 7e)(5d + 7e)

Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
