Please help): Estimate the product of 408 - 52 by first rounding each number to the nearest ten.
A: 20,000
B: 460
C: 450
D: 20, 500​

20500

Step-by-step explanation:

Rounding 408 to the nearest ten will give 410. Since it is above 4, we'll add 1 to the 0 in the tens value and this will be 410.

Rounding 52 to nearest ten is 50.

Therefore, we'll multiply 410 by 50. This will be:

= 410 × 50

= 20500

Therefore, the correct option is D.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
