15−x+y=14−(−x−y) help plz

Mathematics
1 answer:
Inga [223]3 years ago
4 0

Answer:

x=0.5

y=anything

Step-by-step explanation:

15−x+y=14−(−x−y)

15-x+y=14+x+y

<em>Subtract 14 from both sides</em>

1-x+y=x+y

<em>Subtract y from both sides</em>

1-x=x

<em>Add x to both sides</em>

1=2x

2x=1

<em>Divide both sides by 2</em>

x=0.5

Sarah can eat 45 blueberries in 2 minutes. If she eats blueberries for 45 minutes straight, how many did she eat?
BARSIC [14]

Answer:

1012

Step-by-step explanation:

She eats 1012 because:

If she eats 45 in 2 minutes then she eats 22.5 in 1 minute.

This is because 45 ÷ 2 = 22.5

Sarah eats blueberries for 45 minutes so we multiply 22.5 by 45

22.5 × 45 = 1012.5

She ate 1012 full berries.

It takes two apples to make an apple pie. If a chef bought nine apples, the last pie
defon

Hey!

-------------------------------------------------

If a chef bought 9 apples and each pie takes 2 apples then all we have to do is divide.

9 / 2 = 4.5

4 full pies can be made with 9 apples.

4 x 2 = 8 (apples were used to make 4 pies.)

9 - 8 = 1 (apple remaining)

If one pie needs 2 apples, subtract.

2 - 1 = 1 (pies the chef needs to make the last one)

-------------------------------------------------

Answer: The last pie would need 1 more apple.
