A section of a boardwalk is made using 15 boards. Each board is 914914 inches wide. The total width of the section is 144 inches
xeze [42]


<span><span>15 times 9.25 = 138.75 inches.
That leaves

144-138.75 = 5.25 inches for spaces. 
Between the 15 boards are just 14 spaces, however.
So divide 5.25 by 14 and get
3/8" for each space.</span>

<span>Hi there,
14 boards each 9 1/4 inches wide.
14 x 9 1/4 = 138 3/4 inches
144 inches - 138 3/4 inches

= 5 1/4 inches
Spaces between 14 boards
= 13 spaces.
5 1/4 / 13 = 2/5 of an inch.
Hope this helps. :-)</span></span>

Sandy is upgrading her internet service. Fast internet charges $60 for installation $50.45 per month. Quick internet has free in
Dvinal [7]
Fast internet : 60 + 50.45m
Quick internet : 57.95m

to find the number of months they would be equal....set them equal to each other and solve for m, the number of months

60 + 50.45m = 57.95m
60 = 57.95m - 50.45m
60 = 7.50m
60/7.50 = m
8 = m.....so they will be the same at 8 months

6|2x+3|=36 need a mini step by step
ELEN [110]

Answer:

x=1.5

Step-by-step explanation:

We are trying to get x  by itself to see what it equals.

6(2x+3)=36

So first you want to distribute you proprieties.  You do that by multiplying 6 and 2x.  Then multiplying 6 and 3.

12x+18=36

Now in equations where you need to find the variable, whatever you  do on one side of the equal sign, you have to do on the other side.  So now we want to subtract 18 from both sides.

12x+18=36

     -18  -18

Then we divide 12 from both sides.

12x=18

÷12   ÷12

Now you have your answer!

x=1.5
