5. Lerato has determined that the average plastic packet can hold about 4,5kg before it breaks. She buys the following items at Pick 'n Pay:
A 2kg bag of potatoes A 1.4kg fillet steak
A pack containing 12 bananas with an average mass of 120g per banana
Three bottles of juice with a mass of 2kg each A 2 bottle of milk also weighing 2kg
a) What is the total mass of her groceries rounded off to the nearest kilogram?

step-by-step explanation:

.6 is 1/2 of 12

the answer is actually d. i just took the test

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
