We know that
volume of a bar of soap=2*4*0.5----> 4 in³
<span>A bar of soap is sold for $3 individually
</span>so
$3/4-----> 0.75 $/in³
<span>A three-pack of the same soap costs $8
so
$8*(3*4)----> 0.67 $/in</span>³
<span>if you buy the three-pack you save-----> [0.75-0.67]=0.08 $/in</span>³
the answer is
$0.08
The answer is 7
3x-3=18 (take 3 to the other side to solve for x)
3x=18+3 (3 will be positive)
3x=21 (divide both sides by 3)
x=7
Answer:
x = 10.5 in
Step-by-step explanation:
The rectangles are similar, thus the ratios of corresponding sides are equal.
that is
=
( cross- multiply )
2x = 21 ( divide both sides by 2 )
x = 10.5
Answer:
Nope. Moltiplication (and thus divisions) has to be done before any addition or subtractions, unless parenthesis indicate otherwise.
