Lets solve for X
(-a)(x)+4b>9
---------------------------------------------------------
Step one: Add -4b to both sides
---------------------------------------------------------
-ax+4b+-4b>9+-4b
-ax>-4b+9
--------------------------------------------------------
Step 2: divide both d=sides by -a
--------------------------------------------------------
-ax/-a > -4b+9/-a
-------------------------------------------------------
ANSWER: x < 4b-9/a
------------------------------------------------------

So what you do is subtract 4b on both sides so it will be -ax=9+4b then divide x on both sides and you have your answer

How much do you save per class by taking the longer-term class: Weight Training, $200 for 18 weeks (54 classes) or $350 for 36 w

Vsevolod [243]

<u>Shorter term class:</u>

You pay $200 for 54 classes in total. So,

$\frac{200}{54} =3.704$ dollars per class (rounded to 3 decimal places)

<u>Longer term class:</u>

You pay $350 for 108 classes in total, So,

$\frac{350}{108} =3.241$ dollars per class (rounded to 3 decimal places)

Hence, by taking longer term classes, you save around $3.704-3.241=0.463$ dollars.

Rounding to 2 decimal places, you save $0.46 per class.

ANSWER: You save $0.46 per class.

Ricardo has a square hot tub. He wants to build a square pool next to it that is a dilation of the hot tub using a scale factor

ozzi

Answer:

$\boxed{Side \ Length \ of \ hot \ tub = 4.8\ ft.}$

Step-by-step explanation:

Scale Factor = 5

Also,

B'C' = 24 feet

Since both are squares so both have all sides equal.

Sqaure A'B'C'D' is dilated by a scale factor of 5

So,

AB = BC = CD = DA = 24/5 = 4.8 ft.
