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

five less than a number is at least 40. write and solve an inequality to find the minimum value of the number

mina [271]

Answer:

Step-by-step explanation:

5 less than your number is at least 40. Let the number be x. So rephrasing the statement, 5 less than x is greater than or equals 40.

x-5 ≥ 40

x-5+ 5 ≥ 40+5 (adding 5 to both sides to single out the x in LHS)

∴x ≥ 45

In other words, x is at least 45.

Therefore, the minimum value of x is 45.
