Answer:
2
Step-by-step explanation:
Hi there,
In order to solve this expression, you need to substitute x for 1.
You will end up with this expression:
3(
) - 2(1) + 1
Now, simplify the expression.
⇒ 3 - 2 + 1
⇒ 1 + 1
⇒ 2
Therefore, the answer when we evaluate the polynomial for x = 1 is 2.
D. About 3.2 units is the correct answer
No, because since each pennant cost 18$ then 7 pennants should cost 126$. So for Ms. Lee to pay 146$ is not reasonable.
Answer:
6a + (6 x 3) = 60
or
6a + 18 = 60
Step-by-step explanation:
You have 6 students who are assigned an unknown amount of problems. We can write it as 6x. Then each is given 3 more problems, so now we have 6x + (6 x 3). We also know that in all they have 60 problems.
Therefore, the equation is:
6x + 18 = 60
Then just solve
6x + 18 = 60
- 18 -18
6x = 42
x = 7
