Answer:

-36/35

Step-by-step explanation:

First, we need to find the LCM of 5 and 7 (the denominators) which is 35.

-8*7/35 + 4*5/35 = -56/35 + 20/35 =  -36/35

Your answer is -36/35, or if it asks for a mixed number it's -1 1/35.

Tju [1.3M]

Answer:

She need <u>7 kg 400 g</u> of sugar more to complete this order of cookies.

Step-by-step explanation:

Given:

Stevie Baker received 15 kg 700 g of sugar. The production manager noticed that they needed 23 kg 100 g of sugar to make the order of cookies she just received.

Now, to find the quantity of sugar she need to complete this order of cookies.

Quantity of sugar Stevie Baker received = 15 kg 700 g.

Quantity of sugar needed to make the order = 23 kg 100 g.

Now, to get the quantity of sugar she need to complete this order of cookies we subtract quantity of sugar Stevie Baker received  from quantity of sugar needed to make the order:

23\ kg\ 100\ g-15\ kg\ 700\ g

=7\ kg\ 400\ g.

Therefore, she need 7 kg 400 g of sugar more to complete this order of cookies.
