Four more than a number is more than 13

Answer:

4+x>13

x>9

Step-by-step explanation:

This statement represents an inequality. To solve for the missing number first write out the inequality algebrically.

"Four more" implies that 4 is being added to the number. Another way to "a number" is to use the variable, x. So, the left side of the inequality is 4+x. Then, it says that this is "more than" 13. Thus, the greater than sign, >, should be used. This means that the final inequality is 4+x>13.

Next, you can solve the inequality by subtracting 4 from both sides. This gives x>9.

Which represents the solution(s) of the system of equations, y = x2 – 2x – 15 and y = 8x – 40? Determine the solution set algebr

almond37 [142]

Answer:

(5, 0 )

Step-by-step explanation:

Given the 2 equations

y = x² - 2x - 15 → (1)

y = 8x - 40 → (2)

Substitute y = x² - 2x - 15 into (2)

x² - 2x - 15 = 8x - 40 ( subtract 8x - 40 from both sides )

x² - 10x + 25 = 0 ← in standard form

(x - 5)² = 0 ← in factored form, thus

x - 5 = 0 ⇒ x = 5

Substitute x = 5 into (2) for corresponding value of y

y = 8(5) - 40 = 40 - 40 = 0

Solution is (5, 0 )

Maksim231197 [3]

Answer: $50

Step-by-step explanation:

30 × 10 = 40 ft² [garden area]

40 ÷ 25 = 1.6

1.6 ≈ 2

For the area of the entire garden, you need to buy two bottles of fertilizer.

25 × 2 = 50 [fertilization cost for the whole garden]
