5x-1≥-4(x+7)

solve... please

x ≥ - 3

5x - 1 ≥ -4(x + 7)

⇔ 5x - 1 ≥ - 4x -28

⇔ 5x + 4x ≥ - 28 + 1

⇔ 9x ≥ - 27

⇔ x ≥ - 3

Step-by-step explanation:

the number of pounds of strawberries sold is 14 pounds and the number of pounds of peaches sold is 42 pounds

Step-by-step explanation:

Let x represent the number of pounds of strawberries sold.

Let y represent the number of pounds of peaches sold.

Amelia sold 3 times as many pounds of peaches as pounds of strawberries. This means that

y = 3x

Each pound of strawberries sells for $1 and each pound of peaches sells for $4. She made $182 altogether. This means that

x + 4y = 182 - - - - - - - - - - 1

Substituting y = 3x into equation 1, it becomes

x + 4×3x = 182

x + 12x = 182

13x = 182

x = 182/13 = 14

y = 3x = 3×14 = 42
