Hello!
We have to find how fast the car goes a minute
To find this we can do 57/60 since the car goes 57 miles an hour and there are 60 minutes in an hour
This gives us 0.95 miles a minutes
Step 1. Isolate the variable x:
Step 2. Use the simplified inequality to graph:
- Select an OPEN point on x = -5
- Select a ray extending from -5 to positive infinity (GREATER than -5)
I hope this helps!
Answer:
yes
Step-by-step explanation:
So perm cost 2 times as hair cut
perm=2 times haircut
she also needs 5 dollars for lunch
so therefor if 95 is enough to cover it we do
cost=lunch+perm+haircut
cost=5+perm+haircut
subsitute
95=5+2 times haircut+1 time haircut
add like terms
95=5 +3 times haircut
subtract 5 from both sides
90=3 times haircut
diide by 3
30=haircut
subsitute
perm=2 times haircut=2 times 30=60
perm=$60
Answer:
The probability of picking a red marble first then replacing it and getting a black marble is 2/9. (The last option.)
Step-by-step explanation:
Hey there!
The probability of first getting a red marble is 1/3 since we have 1 red marble out of 2 + 1 = 3 total.
We put the marble back. The probability of then choosing a black marble is 2/3, since we have 2 black marbles out of 3 total.
So we get 1/3 * 2/3 = 2/9
The probability of picking a red marble first then replacing it and getting a black marble is 2/9. (The last option.)
Hope this helps, please mark brainliest if possible. Have a nice day. :)
