eg. n is the smallest integer, the other numbers would be (n+1) and (n+2)
Write an equation based on the problem
the sum of integers = 177
n + (n + 1) + (n + 2) = 177
n + n + n + 1 + 2 = 177
3n + 3 = 177
Solve the equation
3n + 3 = 177
3n = 177 - 3
3n = 174
n = 174/3
n = 58
The smallest number of the integers is 58
Answer:
The sides are 24cm, 7cm, and 25cm
Step-by-step explanation:
3x+x-1+3x+1=56 <---- First we combine like terms (the 1's cancel out)
7x/7=56/7 <--- Divide by 7 to isolate the variable
x=8 <--- Now that we've solved for x we need to plug it back into each side
3(8)=24
(8)-1=7
3(8)+1=25
24+25+7=56 <---- Make sure it all adds up to 56
Hope this helps :)

Answer:
There would be 14 cats and 9 dogs
Step-by-step explanation:
In order to find the amount of cats and dogs, we need to set up the system of equations. To do so, start by setting cats as x and dogs as y. Now we can write the first equation to show the total number of animals.
cats + dogs = 23
x + y = 23
Now we can write a second one that shows the difference in the number of cats and dogs.
cats - dogs = 5
x - y = 5
Now we can add the two equations together to solve for x.
x + y = 23
x - y = 5
2x = 28
x = 14
Now that we have the number of cats, we can find the number of dogs by using either equation.
x + y = 23
14 + y = 23
y = 9
