xplain all steps and identify the properties used. n/-3 + 5 > 4
Heres what i did i just want to check my answer
n/-3 + 5 > 4.
subtract 5 from both side:
n/-3 > -1.
Multiply both sides by -3 and reverse Inequality sign
n < 3.

Answer:

Your answer is correct

Step-by-step explanation:

Indeed subtracting 5 from both sides would be n/-3> -1

Multiplying both sides by -3 would give you n < 3 (obviously after reversing the inequality sign)

Answer:

n

Step-by-step explanation:

We have been given an inequality \frac{n}{-3}+5>4. We are asked to solve the given inequality by explaining all the steps.

First of all, we will subtract 5 from both sides of inequality using subtraction property of inequality as:

\frac{n}{-3}+5-5>4-5

\frac{n}{-3}>-1

To solve for n, we will multiply both sides of inequality by -3. We need to remember that when we multiply or divide an inequality by a negative number, the sign of inequality reverses.

\frac{n}{-3}\cdot (-3)

n

Therefore, the solution of our given inequality would be n.

A 40% sugar solution is added to an 85% sugar solution to create 1800 mL of a 60% solution. How much of each solution is used? (
denis-greek [22]

Answer:

Number of ml of 40% sugar = x = 1000mL

Number of ml of 85% sugar used = y = 800mL

Step-by-step explanation:

Let the

Number of ml of 40% sugar = x

Number of ml of 85% sugar used = y

From the above question, our system of equations is given as:

x + y = 1800mL ....... Equation 1

x = 1800 - y

40% × x + 85% × y = 60% × 1800mL

0.4x + 0.85y = 1080.... Equation 2

We substitute 1800 - y for x in Equation 2

0.4(1800 - y) + 0.85y = 1080

720 - 0.4y + 0.85y = 1080

- 0.4y + 0.85y = 1080 - 720

0.45y = 360

y = 360/0.45

y = 800mL

Solving for x

x = 1800 - y

x = 1800 - 800

x = 1000mL

Therefore,

Number of ml of 40% sugar = x = 1000mL

Number of ml of 85% sugar used = y = 800mL
