Step-by-step explanation: To write 60/80 that has a denominator less than 80, we can write reduce this fraction.
Notice that 60/80 can be reduced because 60 and 80 have a greatest common factor of 20. So we divide both 60 and 80 by 20 to get 3/4. Now, this is an equivalent fraction that has a denominator that's less than 80. Image is provided below.
Answer:
see below
Step-by-step explanation:
x^2+8x+26
Take the coefficient of the x term
8
Divide by 2
8/2 = 4
square it
4^2 =16
we need to add 16 to 26 = 16+10
x^2 + 8x+16 +10
(x+4)^2 +10
Answer:
25 Minutes
Step-by-step explanation:
Well, 1/4 of an hour is obviously 15 minutes. So if she read 3/5 of the book in 15 minutes, you have to find how long it took her to read 1/5 of the book. If 15 minutes is 3/5, then 15/3 is 5, which is the time it took to read 1/5 of the book. You add 10 to 15 and you get 25. I hope this helps!
Answer:
First Question: x = -8
Step-by-step explanation:
-12x + 4 = 100
firstly we subtract 4 from 4 which will remove it from the equation and then we also subtract 4 from 100.
Now the equation will be -12x=96
Then we divide -12x by -12 to figure out the value of x and we also dive 96 by -12.
-12x/-12= 96/-12
Answer is x = -8
Hopefully that helped :)
