Hello there!
The correct answer is B. Why? Well, we cannot choose A, because we don't have a multiplication sign. We cannot choose C because we also don't have a multiplication sign. However, since we have a PLUS sign and a Subtraction sign, we can say that the correct answer is option B.
3x + 1 < -2x + 8
We wanna start by subtracting 1 on both sides
3x + 1 - 1 < -2x + 8 - 1
3x < -2x + 7
Add 2x on both sides
3x + 2x < -2x + 7 + 2x
5x < 7
x < 7/5
I hope this answer helps! As always, it is my pleasure to help students like you. If you have any additional questions, feel free to comment them down below. I'll see you around!
Answer:
11/12
Step-by-step explanation:
Answer:
The purpose of this task is to help students see the connection between a÷b and ab in a particular concrete example. The relationship between the division problem 3÷8 and the fraction 38 is actually very subtle.
3÷8 is the number you multiply 8 by to get 3.
38 is the number you get by taking 3 copies of the unit fraction 18.
So 3÷8 is defined in terms of multiplication, and 38 is defined in terms of unit fractions. It is not obvious that these two numbers are the same, so students need opportunities to see that they will necessarily always be the same. Note that if b people share a pies equally, then each person will get ab of a pie by the same kind of reasoning shown in the solution below.
This task is probably best suited for instruction or formative assessment.

I think this is correct:
110 + 75 = 195
195 / 2 = 97.5
I am not fully sure about this, consult your teacher
