Answer: n = 3.6

Step-by-step explanation: When solving an equation that contains decimals, we want to get rid of the decimals as soon as possible.

Notice that 1.2 is taken to the tenths place

but 0.68 is taken to the hundredths place.

To get rid of all decimals in the equation, multiply both

sides by the greatest power of 10 that is required.

So here we multiply both sides by 100 which

moves all decimals 2 places to the right.

So we have (100)(1.2n + 0.68) = (5)(100).

This gives us 120n + 68 = 500.

Now subtract 68 from both sides to get 120n = 432.

Dividing both sides by 120, we find that n = 3.6.

Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together so their kite can fly higher. Wr
torisob [31]

Question:

Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.

Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.

Answer:

y=x +45

y = 45 + x

Step-by-step explanation:

From the complete question, we have:

<u>Jordyn & Teri</u>

<u></u>Rolls = 1<u></u>

<u></u>Extra = 45\ yd<u></u>

<u></u>

<u>Morgan</u>

<u></u>Rolls = 3<u></u>

Extra= 10\ yd

Required

Expression for Jordyn and Morgan

Let the total kite by Jordyn and Teri be represented with y

This is calculated as:

y = Rolls + Extra\ Yard

This gives:

y = 1\ roll + 45yd

1 roll is represented with x.

So:

y=1x +45

y=x +45

This can be rewritten as:

y = 45 + x

How do you solve the systems by substitution y=3x+1 and y=5x-3
rewona [7]
**plug in the first equation into the y of the next.

3x + 1 = 5x - 3
-1 from both sides
3x = 5x -4
-5x from both sides
-2x = -4
divide both sides by negative 2

x= 2

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 85
insens350 [35]
First, "boxes of two sizes" means we can assign variables:   Let x = number of large boxes        y = number of small boxes   "There are 115 boxes in all"    means    x + y = 115      [eq1] Now, the pounds for each kind of box is:     (pounds per box)*(number of boxes) So,   pounds for large boxes     +    pounds for small boxes      =    4125 pounds                  "the truck is carrying a total of 4125 pounds in boxes"          (50)*(x)                   +              (25)*(y)                  = 4125    [eq2] It is important to find two equations so we can solve for two variables. Solve for one of the variables in eq1 then replace (substitute) the expression for that variable in eq2.  Let's solve for x:    x = 115 - y          [from eq1]      50(115-y) + 25y = 4125             [from eq2]      5750 - 50y  + 25y = 4125           [distribute]      5750 - 25y = 4125       -25y = -1625          y = 65             [divide both sides by (-25)]   There are 65 small boxes. Put that value into either equation (now, which is easier?) to solve for x:   x = 115 - y   x = 115 - 65   x = 50    There are 50 large boxes.
