0.27 because if you put it like a whole fraction it would be 3/11 and as a decimal it is 0.27
Answer:
<em>Bert is 11 years old and Max is 17 years old.</em>
Step-by-step explanation:
<u>System of Equations</u>
To solve the system of equations, we use two variables x and y. Let's make:
x = current age of Max
y = current age of Bert
x - 5 = age of Max five years ago
y - 5 = age of Bert five years ago
x + 1 = age of Max one year from now
y + 1 = age of Bert one year from now
According to the conditions of the problem, five years ago, Max was twice as old as Bert, thus:
x - 5 = 2(y - 5) [1]
It's also known a year from now, the sum of their ages would be 30:
x + 1 + y + 1 = 30 [2]
Operating and simplifying [1]:
x - 5 = 2y - 10
x = 2y - 5 [3]
Operating and simplifying [2]:
x + y + 2 = 30
x + y = 28 [4]
Substituting [3] in [4]:
(2y - 5) + y = 28
Simplifying:
3y - 5 = 28
3y = 33
y = 33/3 = 11
y = 11
From [3]:
x = 2*11 - 5
x = 22 - 5 = 17
x = 17
Max is 17 years old and Bert is 11 years old
Answer:
8 eggs are in a carton
Step-by-step explanation:
72 / 9 = 8
<em><u>plz mark as brainliest if correct! Have a nice day!!!</u></em>
Answer:
0.48%
when we subtract 48 from120 we get 72 so 72 is the number of boys are there so we divise them and we get 2 ratio 3
Answer:
There are no solutions
Step-by-step explanation:
3 ( x + 2 ) = 3x - 6
Lets destibute on the left:
3 ( x + 2 )
( 3 * x ) + ( 3 * 2 )
3x + 6
3x + 6 = 3x - 6
add 6 to each side:
3x + 12 = 3x
Subtract 3x from each side:
12 = 0
12 ≠ 0
