This model represents an equation
1 answer:
Answer:
Step-by-step explanation:
The model above shows a weigh balance which can be represented by an equation have two sides, of which must be equal to each other.
On the right of the equation, we have 5 "x" and 1 "-", which can be represented as: .
On the other side, we have 6 "-1", which can be represented as: -6.
The equation that can be used to solve x is:
Solve for x. Add 1 to both side
Divide both sides by 5

From the table, we observe that the domain of the function is {Mon, Tues, Wed, Thurs, Fri} and the range is {1, 2, 3, 4, 0}
So, S(Mon) = 1
S(Tues) = 2
S(Wed) = 3
S(Thurs) = 4
S(Fri) = 0
Hence,
Answer:
The three consecutive integers are 12, 13, 14.
Step-by-step explanation:
Encode the question in an equation. We are given two facts: (1) the three integers are consecutive, and (2) they relate to each other through a sum.
Pick any of the integers (first, second, or third) and call it n. Then write the two others correspondingly in terms of n. I pick the middle one as n, so the three consecutive integers are (n-1), n, (n+1). That's (1). As for (2), here is the fact:
Lo and behold, one equation with one unknown! Easy to solve for n to give us the middle integer, n:
The three consecutive integers are 12, 13, 14.
