Hello from MrBillDoesMath!
Answer:
58
Discussion:
Suppose the 2-digit number is "ab". That is, 10a + b.
Sum of digits = 13 => a + b = 13 (*)
Digits reversed if 27 added to number => (10a + b) + 27 = 10b + a (**)
(**) =
(10a + b) + 27 = 10b + a => subtract 10b, then a, from both sides
9a -9b = -27 => divide both sides by 9
a - b = -3
From (*), a+ b = 13 so
(a-b) + ( a+b) = -3 + 13 =>
2a = 10 =>
a = 5
As a +b = 13, 5 + b = 13 => b = 8
Hence the number "ab" is 58
Thank you,
MrB
Answer:
1) x = 4 2) x = 4 3) x = -4 4) x = 3 5) x = 5 6) x = 9 7) x = -8
8) x = 11 9) x = -5 10) x = -4
Step-by-step explanation:
Alternate Exterior and Alternate Interior angles are equal to each other. Just set the numbers or equations the give you equal to each other.
Question 1: Question 2: Question 3: Question 4:
33x+3=135 120=31x-4 120=x+124 40x+5=42x-1
33x=132 124=31x -4=x 6=2x
x=4 x=4 x= -4 x=3
Question 5: Question 6: Question 7: Question 8:
20x+4=19x+9 11x= -9+12x 80=x+88 10x+20=12x-2
-5= -x -x = -9 -8 = x 22=2x
x=5 x= 9 x= -8 x=11
Question 9: Question 10:
70=x+75 130=x+134
-5 = x -4 = x
x = -5 x= -4
16 is the solution to this if you're multiplying the 2
Answer:
So, there are 3 cards in total, which means your pobability of picking one card out of the 3 cards is %33.33. So the probability of picking a 7 is 1/3. Because the other two numbers are greater than 7, and you already picked 7 so you cannot pick it again, the probabitily of pick a number greater than 7 is %100, or 3/3.
I hope that answers your question! :)
