Answer 1

we know that

If the temperature is no more than 60 degrees

that means

that the temperature is less than or equal to 60

Let

T ------> the temperature

$T\leq60$

In a number line the solution is the shaded area at left of T=60 (closed circle)

therefore

the answer is the option B

Part 2

In this problem

we have an identity in equation 3

because the left side is equal to the right side

Part 3

we have the equation

7x-3y=-21
