Show how to solve the problem 378 times 6 using place value with regrouping. explain how you knew when to regroup

2268

Step-by-step explanation:

We have to solve the problem 378 dimes 6 using place value.

Place of 8 in 378 = once

Place of 7 in 378 = Tens

Place of 3 in 378 = Hundred

Now we can write this number as ( 300 + 70 + 8 )

( 300 + 70 + 8 ) × 6 = (300) × 6 + 70 × 6 + 8 × 6

                                = 1800 + 420 + 48

                                = 2268

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
