If a dozen exercise books cost 144, what will 14 of the same books cost
Aleksandr-060686 [28]
168


So you take the 144 divide 12(the dozen) so we could find how much 1 cost, it was 12. You added 2 more books so we add(12x2)+(144). That equals to 168

Hope this helps!

Answer:

I disagree with Luis's claim. While 8*3=24, 8^3 is 512mm. Which is 488mm more than 24mm.

201 inches.

Step-by-step explanation:

They use the expression s^3 to find the volume of plastic to make each cube. Luis says that if s=8, then the volume is 24 cubic mm. I disagree with Luis's claim. While 8*3=24, 8^3 is 512mm. Which is 488mm more than 24mm.

#3

Part A

Blue: 3ft - 36in

Red: 60in - 5ft

Yellow: 2.5ft - 30in

Green: 12ft - 144in

Purple: 240in - 20ft

Part B

1 foot = 12 inches

16.75ft = 201in

I'm not sure how to do the expression

but if 1 foot = 12 inches, and you substitute 16.75 for a foot, then you have 201 inches.

vesna_86 [32]

Answer:

see explanation

Step-by-step explanation:

(a)

Consider the denominator

To obtain 5xy from x , multiply by 5y

Thus numerator is multiplied by 5y, that is

\frac{1}{x} = \frac{5y}{5xy}

(b)

Consider the numerator

To obtain 5ab² from ab, multiply by 5b

Thus denominator is multiplied by 5b, that is

\frac{ab}{2c} = \frac{5ab^2}{10bc}
