Answer:

The number is: 120

Step-by-step explanation:

We have one-half of "a" decreased by 20 is 40

(1/2)a-20=40

(1/2)a=60

a=120

34699 to nearest ten thousand
xz_007 [3.2K]

Ones place: 9

Tens place: 9

Hundreds place: 6

Thousands place: 4

Ten thousands place: 3

Which is 34,699

Now that we know 3 is in the ten thousand's place.

So then go from 3, and jump too 4. If the number is higher then 5, the 3 would become a 4. If the number is lower then 5, 4 would become a 0 and so will the rest of the number's too the right.

34,699 ---> 30,000

That being said, the answer is 30,000!

I hope this help's! :)

Answer: $27.50

Step-by-step explanation:

45% = 0.45

$50 × 0.45 = $22.50

$50 - $22.50 = $27.50

Don't worry because I be the dumb too. Me could have been using 0.55 as multiplier but am too dumb so made meself get extra step

Lol

You could have also done:

$50 × 0.55 = $27.50
