Estimate. Round each number to the nearest whole number before you multiply. 9.92 x 17.72 * A. about 153 B. about 180 C. about 170 D. about 162

i think it B because 9.92*17.72 is 175.7824 and when u substract 175.7824 by 180 u find smallest number than when u substract 175.7824 by 170

Step-by-step explanation:

hope it help and hope it make sense

answer: 48

just remember to use pemdas:

parentheses

expressions

multiplication

division

addition

subtraction

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
