Answer:
1157 / 500
Step-by-step explanation:
They would be 69 and 70.
Your equation would be x + (x + 1) = 139
X would be the first integer and x + 1 would be the second
You would then solve the equation to get x as 69
X + 1 would then be 70
Answer:
20n
Step-by-step explanation:
One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.
1 pretzel = 20 calories
n pretzel = x
Cross Multiply
x × 1 pretzel = n pretzel × 20 calories
x = n pretzel × 20 calories/1 pretzel
x = 20 n
Therefore, an algebraic expression for the total number of calories in n pretzels = 20n
