Answer:
84
Step-by-step explanation:
let a be the 1's digit and b the 10's digit, then
a = 2b ← twice the 10's digit, thus
sum = 2b + b = 12, that is
3b = 12 ( divide both sides by 3 )
b = 4
and a = 2b = 2 × 4 = 8
The 2 digit number is 84
I think the answer is x2 +64 but I hope you get it right good luck ! I hope it is 64 thanks
Answer is (1 9/20) because 1 and 45/ 100 can be simplified by divided 45/100 by 5. 45 divided by 5 is 9 and 100 divided by 5 is 20. A mixed number is a combination of a whole number and a fraction. The whole number is 1 and the fraction is reduced to 9/20.
The sum of their ages equals 80.
Gabrielle is 3 times older than Mikhail
Two numbers that have a sum of 80, with one number being 3 times the other are:
Gabrielle’s age: 60
Mikhail’s age: 20
60 + 20 = 80
20 x 3 = 60
Mikhail is 20 years old.
