Recall your d = rt, distance = rate * time.
now, let's say she lives "d" miles away, and so if Billy goes say at "r" mph fast to her house, he gets there in 1hr.
now, if he goes 20 mph slower, namely " r - 20 " mph, he gets there in 2 hours, same "d" miles.
For this case we have the following inequality:
We multiply both sides of the equation by -1.
By doing this, change the symbol of the inequality.
We have then:
From here, we clear the value of x.
We have then:
Answer:
The solution set is:
{x | x R, x < -12}
Answer:
Jesse should buy a new bag in 16 days.
Step-by-step explanation:
He uses 18.75 grams a day.
We can multiply the amount of grams by the amount of days.
18.75 x 16 = 300
He stops using the bag when he uses 300 grams.
So he uses 1 bag for 16 days
1 bag can last for 16 days.
Answer:
X = 45
Step-by-step explanation:
90+45+X=180
135 + X = 180
X = 180 - 135
X = 45
hope it helps!
1 and 2 are less then 3
4=3+1 but you cant get 1 from 7 or 3 so 4 is impossible. So is 5, 6, 8, and 20.
Bolded numbers are answers.
