7x + 2y=24<br> 8x + 2y=30
Bumek [7]

Answer:

x=6 y=-9

Step-by-step explanation:

  • Layer the equations on each other as you would in a subtraction problem:

               8x + 2y=30

               7x + 2y=24  

  • Subtract the equation just like you would normally. This should leave 1x=6 or x=6.
  • Now that you have your x value, plug it in as x for one of the equations. For the 2nd equation, this leaves:

               42+2y=24 then

               2y=-18 then

               y=-9

  • Double check your y value by plugging x=6 into the first equation. This should also leave y=-9.

Write the following sentence into an expression using x as your variable: Myrna and Tom collect stamps. Tom has four more than h
balandron [24]

Answer: f(x) = x/2 + 4.

where f(x) is the number of stamps that Tom has, and x is the number of stamps that Myrna has.

Step-by-step explanation:

The statement is:

"Tom has four more than half the stamps that Myrna has"

For how is written, we can model the number of stamps that Tom has as a function f(x).

f(x) represents the number of stamps that Tom has, and x is the number of stamps that Myrna has.

Then:

"four more than a number" is written as:

N + 4 (where N is the number)

"Half the stamps that Myrna has" is written as:

x/2.

Then the whole statement can be modeled as:

f(x) = x/2 + 4.

notice that we have x/2, and f(x) must be a whole number, so Myrna must have an even number of stamps (in that case x/2 will be integer)

PLEASE HELP!!
Elena-2011 [213]
For this case we have the following equation:
 S = 0.159 + 0.118logD
 Substituting S = 0.2 we have:
 0.2 = 0.159 + 0.118logD
 From here, we clear the value of D.
 We have then:
 0.2 - 0.159 = 0.118logD
 logD = (0.2 - 0.159) / (0.118)
 logD = 0.347457627
 10 ^ (logD) = 10 ^ 0.347457627
 D = 10 ^ (0.347457627)
 D = 2.23 mm
 Answer:
 
The average diameter, D, of the sand particles for a beach is:
 
D = 2.23 mm
