Marina86 [1]

Answer:

The number is 9.

Step-by-step explanation:

Lets write this as an equation first. We'll substitute the number for the variable x.

80 - 3x = 5x + 8

First, let's add 3x to both sides.

80 - 3x + 3x = 5x + 3x + 8

80 = 8x + 8

Next, let's subtract 8 from both sides.

80 - 8 = 8x + 8 - 8

72 = 8x

Finally, let's divide both sides by 8.

72/8 = 8x/8

9 = x

"x" is 9.

So the secret number is 9.

P.S.

Tpy6a [65]

Answer:

$3\frac{13}{20}=3.65$ kg.

Step-by-step explanation:

Let S be amount of strawberries picked in the afternoon.

We have been given that Sheldon harvest the strawberries and tomatoes in his garden. He picks 1 2/5 kg less strawberries in the morning than in the afternoon and the strawberries picked in morning are $2\frac{1}{4}$ kg.

To find the amount of strawberries picked by Sheldon in the afternoon we will add $2\frac{1}{4}$ and $1\frac{2}{5}$ :

$S= 2\frac{1}{4}+1\frac{2}{5}$

Upon converting our given mixed fractions into improper fraction we will get,

$S= \frac{9}{4}+\frac{7}{5}$

Now let us have a common denominator.

$S=\frac{9*5}{4*5}+\frac{7*4}{5*4}$

$S=\frac{45}{20}+\frac{28}{20}$

$S=\frac{45+28}{20}$

$S=\frac{73}{20}$

$S=3\frac{13}{20}$

$S=3.65$

Therefore, Sheldon picked $3\frac{13}{20}=3.65$ kg of strawberries in the afternoon.
