Though I don't know #24, I know #25.
Take 15% of 31.77 and you should get 4.7655.
Now add 31.77 with 4.7655 and you should get 36.5355.
Round 36.5355 to the nearest hundredth.
Your final answer is $36.54
Answer: 97 stickers
Step-by-step explanation:
Marie has 87 stickers in her collection.
Each week she collects 5 and gives away 3.
The total number of stickers she gains per week is therefore:
= 5 - 3
= 2 stickers per week
In 5 weeks therefore, she would have collected:
= 2 * 5
= 10 stickers
Add that to the original number:
= 87 + 10
= 97 stickers
.5 equals one half.
8 is 8 over one (8/1)
8 + 1/2 = 8 1/2
To make it an improper fraction multiply the denominator (bottom number) by the whole number and add the numerator (top). 8*2=16+1=17
Then, put this number over the existing denominator. 17/2
It looks to me that the answer would be 4x-3
Answer:
900
Step-by-step explanation:
The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3.
Let the number of people who own a flip phone=x
If 600 more people own a smartphone than a flip phone, then the number of people who own a smartphone=x+600
To find x, we express the ratio and population as an equality.
5:3=x+600:x
Expressing the ratios as fractions would give:

Next, we cross multiply
5x=3(x+600)
Open the brackets by expansion.
5x=3x+(3 X 600)
5x=3x+1800
Subtract 3x from both sides.
5x-3x=3x-3x+1800
2x=1800
Divide both sides by 2
x=900.
Since x=900, the number of people who own a flip phone is 900.
