Question

1. Solve. y-5 is less than or equal to 6 (1 point)

A) y is less than or equal to 1
B) y is less than or equal to 11***
C) y is less than or equal to -11
D) y is less than or equal to 30

2. Solve. 8 > d-2 (1 point)
A) d < 10
B) d > 10
C) d < 6
D) d > 4

3. Solve. 3.8 is greater than or equal to b + 4 (1 point)
A) b is less than or equal to -0.2
B) b is less than or equal to 0.2
C) b is less than or equal to 7.8
D) b is less than or equal to 1.8

Also, if anyone knows what the alt code is to make a less than or equal to, and a greater than or equal to symbols, that would be awesome. These are the only alt codes I know, °, •, ÷, ², ®, and √.

Answer 1

Greetings!

1)

If y - 5
`\leq` 6, then you can simply move the negative five overt to the other side, making sure to change the sign, making it a positive:

`y \leq 6 + 5` simplified to
`y \leq 11`

2)

Again, simply move the negative two over to the other side, changing the sign from a negative two to a positive two:

`8 + 2` > d , or simplified 10 > d

3)

Again, simply move the positive 4 over to the other side making it a negative four:

3.8 - 4 ≥ b or simplified to -0.2 ≥ b

I attatched a screenshot of the alt numbers for the different signs.

Hope this helps!
