The first thing we must do for this case is to define variables:
 x: text messages
 Y: pictures
 We write the system of equations:
 0.05x + 0.10y = 4
 x = y + 5
 Solving the system we have:
 x = 30
 y = 25
 Answer:
 
you send:
 
30 text messages
 
25 pictures

The length of a new rectangular playing field is 6 yards longer than double the width. If the perimeter of the rectangular playi
Andru [333]

Answer:

width = 47

Length = 100

Step-by-step explanation:

The perimeter of the rectangle has the formula

P = 2(L + W)

P = 2L + 2W

Length = 6 yards longer than double it's width.

Mathematically,

length = 6 + 2W

We put this into the formula for perimeter

P = 2(6+2W)+2W

294 = 12+4W+2W

294 = 12+6W

Collect like terms

294-12 = 6W

282 = 6w

Divide through by 6

W = 282/6

W = 47

This is the width

Remember length = 6 + 2(W)

So

Length = 6+2(47)

= 6+94

= 100

Width = 47

L = 100

These are the dimensions

The Probabilty of rolling a 1 on a 6 sided biased dice is 0.85
arlik [135]

Answer:

false

Step-by-step explanation:

This statement is false. There are a total of 6 sides on a six-sided die therefore, every roll is a one in six chance of getting a single number since only one number can be obtained per roll. So that would mean that the probability is

\frac{1}{6}   or 0.16666 or 16.66%

That would be the actual probability of rolling a 1 on a single roll of a six-sided die, not 0.85
