3x-5=10
To find the number:
3x=10+5
3x=15
x=15/3
x=5
Answer:
Uhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Step-by-step explanation:
The second one, K
-15
because, for us to get a positive number in a fraction, when the denominator in negative, the numerator must also be negative.
so, -15, or anything less than -15 (when put into the numerator) will be equal to or greater than 3
Hope this helps!:)
Answer: 9mph and 18mph
Step-by-step explanation:
T=D/R
If you take the distance, 81, and divide it by the rate of the cyclists combined, x+x-9 or 2x-9, you will get the time they meet at, 3 hours. To make this an equation. you would have
3=81/(2x-9)
If you solve this equation, x=18. This means one of the cyclists's rate is 18 mph, and the other, x-9, is 9 mph
I think as that is a variable so when you like add there is already a constant so it is 1
1+1+1+1= 4
x=1
