So use undistributive properyt]
ab+ac=a(b+c)
so factor 24a dadn 28 to find 'a' the common factor
24=2 times 2 times 2 times 3 tiems a
28=2 times 2 times 7
common one is 2 itmes 2=4
a=4
4(2 times3 times a)+4(7)=4(6a)+4(7)=4(6a+7)
Since the question only asks for bagels, put the cream-cheese idea aside.
The total spent has to be less than $7 so an equation can be this: $0.75x<$7 where x is the number of bagels
One less limb than yesterday! so let’s assume like a regular human the mutant has 4 limbs. he grows another 5 and now he’s got 9 limbs. he loses 12 so 9-12 equals -3, plus 2 is -1.
4r+2=-26
4r=-28 (subtract 2 from both sides)
r=-7 (divide both sides by 4)
Answer: (D) 11
Step-by-step explanation:
Let the first digit x composed of ab and the second digit y composed of reversed of ab =ba
The sum of x and y will be
x+y = ab+ ba
x+y= (10.a + b) + (10.b +a)
x+y= 10a+b+10b+a
x+y= 11a+11b
By factorization
x+y= 11(a+b)
Therefore 11 is compulsory factor of x and y
