Solutions

Divide both sides by 10

x+3=9 / 10

Subtract 3 from both sides

x=9 / 10 −3

 Simplify 9 / 10 −3 to −21 / 10

x=−21 / 10


Decimal = -2.1

PLEASE help a girl out! :)What is the actual area of the room?

andrey2020 [161]

Answer:

$=75$ $ft^{2}$

Step-by-step explanation:

Area is found by mulitplying width and height.

$A=7.5(5)\\$

$A=37.5\\$ in

The ratio is 0.5in : 1ft, so if you multiply that ratio to the answer, you should get the answer in feet.

$37.5$ in x $\frac{1ft}{0.5in}$ $=75$ $ft^{2}$

Sam and Lou need a total of 1 foot of wire for a science project. Sam's wire measured 7/8- foot long. Do they have enough wire f

Reil [10]

Answer:

Yes, Sam and Lou have enough wire for science project.

Step-by-step explanation:

There is some data missing in the question, so complete question is below:

$Sam\ and\ Lou\ need\ a\ total\ of\ 1\ foot\ of\ wire\ for\ science\ project.$ $Sam's\ wire\ measured\ 8/12\ foot\ long.\ Lou's\ measured\ 7/8-\ foot \ \ long.$ $Do\ they\ have\ enough\ wire\ for\ the\ science\ project?$ $Explain \ your\ reasoning.$

Now, to get that whether they have enough wire for the science project or not.

Measurement of Sam's wire = $\frac{8}{12} \ foot.$

Measurement of Lou's wire = $\frac{7}{8}\ foot.$

Now, adding both the wires of Sam and Lou:

$\frac{8}{12} +\frac{7}{8} \\\\=\frac{16+21}{24} \\\\=\frac{37}{24}$

$=1\frac{13}{24} \ feet.$

As, Sam and Lou need a total of 1 foot of wire for the science project.

And, we see that the Sam's wire and Lou's wire combining gets $1\frac{13}{24}\ feet$ which is more than 1 foot.

Thus, wire they have is enough for science project.

Therefore, yes, Sam and Lou have enough wire for science project.
