Remember  you can do anything to an equaiton as long as you do it to both sides

3x-2x=7-5
combine like terms

Solve the following equation: |-3x+3|-9=12
photoshop1234 [79]

Answer:

\large\boxed{\left \{ {{x\: = \: 8} \atop {x\: =\: -6}} \right. }\\

Step-by-step explanation:

\left| -3x+3  \right|  -9=12

At first, let's add - 9 to both the sides. So,

\left| -3x+3  \right|  -9=12\\|-3x+3|=21

Now, using the definition of absolute value, we can change the equation to..

-3x+3=21 \\-3x+3=-21

By, subtracting 3 from both the sides,

-3x=18 \\-3x=-24

Now, divide both the sides by 6,

x=-6 \\x=8

We now have 2 values of x. They are...

\large\boxed{\left \{ {{x\: = \: 8} \atop {x\: =\: -6}} \right. }\\

Hope it helps!

The family size bottle of sunscreen holds 12121212 fluid ounces (fl oz)(\text{fl oz})(fl oz)(, start text, f, l, space, o, z, en
Musya8 [376]

Answer:

The regular bottle holds 9 fl oz less

Step-by-step explanation:

Given

Family Size =  12 fl oz

Required

Determine the size held less by the regular bottle

From the question, we have that the regular bottle holds 75% less;

Regular\ Size = 75\% * Family\ Size

Substitute 12 fl oz for Family Size

Regular\ Size =75\% * 12\ fl\ oz

Convert percentage to fraction

Regular\ Size = \frac{75}{100} * 12\ fl \oz

Regular\ Size = \frac{75 * 12\ fl\ oz}{100}

Regular\ Size = \frac{900\ fl\ oz}{100}

Regular\ Size = 9\ fl\ oz

<em>Hence, the regular bottle holds 9 fl oz less</em>
