Answer:
4%
Step-by-step explanation:
We can write the following equation:
20 * (x / 100) + 60 * 0.12 = 80 * 0.10 (Note that since we're writing the percentages as decimals, x% becomes x / 100 as a decimal.)
x / 5 + 7.2 = 8
x / 5 = 0.8
x = 4%
Answer:
Hi,can you please answer mine too it's question 9-12 I really need the answer because I have to pass it tomorrow morning:(
Step-by-step explanation:
about your question I'll put it in the comment section:)
The total is 219 miles.
He rides at 38 mph and walks at 4 mph for 8 hours. If he rides for h hours, he walks for 8-h hours.
Set them equal to each other:
219=38h+4(8-h)
Solve and you should get 5.5 hours on the bicycle and 2.5 hours walking.
Answer:
First Space: 49
Second Space: 33
Third Space:-99
Fourth Space: -99
Fifth Space: 10
Sixth Space: -89
Step-by-step explanation:
First Space: for the first space you would do -7 times -7 because it is squared so you would get 49 because a negative and a negative and a negative make a positive.
Second Space: For the second space you have to do 49-16 because you already found the first space and the answer would be 33.
Third Space: For the third space you would do the answer you got from the second space which is 33 and multiply by -3 because -3 is outside the brackets. The answer would be -99.
Fourth Space: You would just put the same thing as the third space and put -99.
Fifth space: To find the fifth space you have to do 4 ÷ 2/5. To find this part you have to do 4 times the reciprocal (when you flip the fraction) and you would get 4 times 5/2. Then you can cross the denominator (bottom of the fraction) and make the 4 a 2 because 4 ÷ 2=2. Next you do 2 times 5 and get 10 as a answer.
Sixth Space: For the final answer you would use the fourth and fifth space. You would do -99+10 which is -89.
Hopefully this helps :)
