Answer: Aeva sold 69 red pins.

Step-by-step explanation:

Let x represent the number of pins with green beads that Aeva sold.

Let y represent the number of pins with red beads that Aeva sold.

Each pin with green beads sells for $3. Each pin with red beads sells for $2. She raised $312. It means that

3x + 2y = 312- - - - - - - - - - -1

The number of pins with green beads is 11 fewer than the number of pins with red beads. It means that

x = y - 11

Substituting x = y - 11 into equation 1, it becomes

3(y - 11) + 2y = 312

3y - 33 + 2y = 312

3y + 2y = 312 + 33

5y = 345

y = 345/5

y = 69

x = y - 11 = 69 - 11

x = 58

1. The sum of x and -45 is at most 35
Lorico [155]

Answer:

The given set of equation are:   x+ (-45) ≤  35  ,  x - (-45) ≥  35

For the given equality to be true, x  ≤ 35

Step-by-step explanation:

Here, given the first number = x

Second number  = -45

Now, Sum of x  and - 45 is at most 35.

⇒ x+ (-45) ≤  35

Also,  The difference of x and -45 is at least 35.

⇒ x - (-45) ≥  35

Now, simplifying the given set of equations:

x  - 45  ≤  35  ⇒    -x - (-45) >   - 35   ( as 3  <  4  ⇒ -3  > -4)

or, -x  + 45  >  - 35

and second equation is x  + 45 ≥  35

Now, solving both the equations by not taking sign of inequality in to the consideration, we get

x - 45  = 35

x + 45 = 35  

Adding both equations,we get:   ⇒ 2x = 70

                                                          or x = 35

Hence for the given equality to be true, x  ≤ 35
