Answer: The answer is x = 65 - 60y.
Step-by-step explanation: Given that Miguel is the grandfather of Raul and Paula is Raul's sister.
Now, let 'x' years be the age of Raul and 'y' years be the age of Raul's sister (Paula).
Also, given is the following information -
Raul's age = Grandfather's age - 60 × sister's age.
Since the age of Miguel, Raul's grandfather is 65 years, so we can write the following equation to find Paula's age
Thus, we can find Paula's age (y) using the equation
where 'x' is the age of Raul.
If there is $1,000 for the pipes, then you can buy 5 steel pipes for $500 and to plastic for 500 too.
Answer:
(x-4) (x-4)
Step-by-step explanation:
foil [first, outside, inside, last]
x^2 -8x = 16
(x-4) (x-4) = x^2 -4x -4x +16 = x^2 -8x +16
The way you should go about solving this really depends on how your teacher taught you...However, here's what I would recommend...
You know that 1/2 an hour is equal to 30 minutes, and 3/4 of an hour is equal to 45 minutes.
Using this you can then solve for how many pages she read per minute by dividing the number of pages read by the number of minutes read:11 pages/ 30 minutes to give you Monday's reading speed,and18 pages/ 45 minutes to give you Tuesday's reading speed.
Next, to calculate a percentage increase you need to do the following:
1. Determine the difference between the speeds (this means you will subtract Monday's reading speed from Tuesday's reading speed.)
2. Next you take that number and divide it by Monday's reading speed.
3. Multiply that answer by 100 to get the percentage.
I'm not going to tell you the speeds, as you should try to attempt to solve it by yourself, and I'm sure you need to show your work. I will however tell you that you should find there was a 3.3% increase from Monday to Tuesday.
If you need more help, let me know!
