Solutions
1) <span>Lets use n as alex's number
</span>⇒ n x 1000
⇒ n ÷ 10
⇒ = 475
To solve the problem do the opposite steps
475 ÷ 1000 = n
n = <span>0.475
</span>
0.475 x 10 = n
n = 4.75
CHECK YOUR WORK
4.75 x 1000 = 4750
4750 ÷ 10 = 475
The answer is correct
⇒ The answer Alex is thinking of is 4.75

40
Step-by-step explanation:
10 + 30 = 40 difference
Answer: 5
Explication: Do PEMDAS first solve the parenthesis which is 6x19= 114 then add the 25 which equals 139. Now slice the exponent 6^2=36 then multiply by 4 which equals 144. Subtract 144-139 and you get 5
Answer:
20
Step-by-step explanation:
40 x 50% = 20
So 50% of 40 equals to 20. Now, since it says decreased by 50%, we have to subtract 20 from 40 because we already know that 20 is the 50%. So 40 - 20 gives you 20.
I think that is the second one but I’m not really sure , sorry if isn’t correct
