Jackson estimated 637 ÷ 78 as 640 ÷ 80. He reasoned that 64 tens divided by 8 tens should be 8 tens. Is Jackson’s reasoning corr

Sholpan [36]

Answer:

the correct solution has been explained

Step-by-step explanation:

Jackson,s reasoning is incorrect because it should be 8 ones and not 8 tens that would give 64

$\frac{640}{80} = \frac{64}{8} = 8$

Moreover, $\frac{637}{78} is\ not\ equal\ to \frac{640}{8}$

as $\frac{637}{78}= 8.16$

whereas $\frac{640}{80}$ = 8

clearly, both quantities are different

Find f(6) if f(x)=x^2 divided by 3x+x

Alinara [238K]

So, if I'm understanding you correctly, f(x)=x^2 divided by 3x+x, or
f(x) = (x^2)/(3x+x)
f(6) --> plug the 6 in to all values of x --> f(6) = (6^2)/(3×6 + 6) = 36/(18+6)
= 36/24 --> both are divisible by 12, so 36/12=3 and 24/12=2, now we have the reduced (simplified) answer:
f(6) = 3/2, or 1 1/2, or 1.5
