So basically
D=RT
distance=rate times time
D=233
carlos speed=55
maria speed=50
total time=4.4 hours
so therefor we have to represent
carlos time
maria time
carlos distance
maria dstance
let's say that
remember that whatever carlost drove is 233 minus maria (time and distance)
and since we are solving for maria time and distnace, solve in terms of them
maria time=t
maria distance=d
carlos time=4.4-t
carlos distance=233-d
remember total D=RT
find their seperate equations
carlos
233-d=55(4.4-t)
maria
d=50(t)
use them to solve
233-d=55(4.4-t)
subsitute 50(t) for d
233-50t=55(4.4-t)
add 50t to both sides
233=55(4.4-t)+50t
distribute using distributiver protperty (a(b+c)=ab+ac)
55(4.4-t)=242-55t
233=242-55t+50t
add like terms
233=242-5t
add 5t to both sides
233+5t=242
subtract 233 from both sides
5t=9
divdie both sides by 5
t=1.8
maria drove 1.8 hours
the answer is A
Considering the opposite of the rational number -1/2, the location of the snail is represented by the number 1/2.
<h3>What is the missing information?</h3>
This problem is incomplete, but researching it on a search engine, we have that:
- The fish is located at -1/2 feet.
- The snail is located at the opposite location of the fish.
<h3>What is the opposite of a rational number?</h3>
The opposite of a rational number a is given by -a, that is, it is the number with the opposite signal.
Hence, the <u>opposite of -1/2 is 1/2</u>, and the location of the snail is represented by the number 1/2.

Step-by-step explanation:
Answer: 8
Step-by-step explanation:
6x-3=45
6x=48
x=8
You are given that all three sides are equal. You also know that all three angles are also equal. Therefore since all three angles are equal and every triangle has 180 degrees, each angle is 180/3 = 60
So
7x - 3 = 60 Add three to both sides
7x - 3 + 3 = 60 + 3 Combine
7x = 63 Divide by 7
7x/7 = 63/7
x = 9 And that's your answer.
