Answer:
110 km
Step-by-step explanation:
He walks 22 km every day, for 5 days
d = (km in one day) * (days)
d = 22 * 5
d = 110
Answer:
34
Step-by-step explanation:
1. if to guess the Caleb's age is 'x' years and Linda's age is 'y' years now, then
2. according to the 'sum of the ages of Caleb and Linda is 55 years' it may be written: x+y=55 - the first equation of the system;
3. according to the condition '8 years ago, Caleb's age was 2 times Linda's age' it may be written: (x-8)(y-8)=2 - the second equation of the system;
4. if to make up the system of two equation and calculate the values of 'x' and 'y':
5. if x=34, then Caleb is 34 old now.
First, let’s break down the equation by combining like terms. You get 1a-4b, therefore making it answer choice b.
The answer you're looking for is A: 3
5x-1=14
+1 +1
(the -1 cancels out)
5x=15
(divide by 5 on both sides)
x=3
:P I hoped this helped!
