3 0

Answer:

Annie thought of the number ; '7'

Step-by-step explanation:

<em>Let the no. be; 'x'</em>

The no. multiplied with 2 = 2x

Then subtracted from 4 = 2x - 4

Final answer= 10

Thus, 2x - 4 = 10

<u>Now lets solve the equation;</u>

2x = 10 + 4 = 14

x = 14 divided by 2 = 7

John's patio is 5 feet long<br> and has an area of 1.30<br> square feet<br> How wide is the patio?
Sophie [7]

Step-by-step explanation:

so, I assume the patio is a true rectangle.

the area of a rectangle is

length × width

in our case that means

1.3 = 5 × width

width = 1.3 / 5 = 0.26 ft

so, this is just a very narrow strip of 0.26ft × 5 ft.

I would not call that a patio ...

or was it a typo, and the area is actually 30 ft² ?

then we would have

30 = 5 × width

width = 30 / 5 = 6 ft

What is the percent of change from 14 inches 26 inches
PolarNik [594]
To find the percent of anything, you divide what you have from the total (or the smaller number over the bigger number). In this case, you will do 14/26.
14/26=0.53846
I'm going to round to the hundredths: 0.54
Move the decimal place two times to the right: 54
The percent change from 14 inches to 26 inches is 54%

Mr. Parker has 982 pounds of grain. He feeds 240 pounds ro his pigs and 460 to his cows. How much grain does he have left
denpristay [2]

Starting amount: 982 pounds of grain

Since Mr. Parker fed 240 pounds of grain to his pigs, subtract 240 pounds from 982 pounds of grain.

982 - 240 = 742

After feeding pigs: 742 pounds of grain

Mr. Parker fed another 460 pounds of grain to his cows from his 742 pounds, so subtract 460 pounds from 742 pounds.

742 - 460 = 282

After feeding pigs and cows: 282 pounds of grain

Mr. Parker has 282 pounds of grain left.
