Answer:
100 miles
Step-by-step explanation:
Given :
To work :
speed = 50mph
Let time taken = x
From work :
speed = 40mph
30 minutes = 30/60 = 0.5
Time taken = x + 0.5
Distance from home to work :
Distance = speed * time
To work distance = from work distance
This can be algebraically expressed as :
50 * x = 40(x + 0.5)
50x = 40x + 20
50x - 40x = 20
10x = 20
x = 20/10
x = 2
Hence,
Distance = 50 * 2 = 100
The the distance from home to work = 100 miles
(x^1/2 y^-2/3)^-6
= x^(1/2*-6) y^[(-2/3) *(-6)]
= x^-3 y ^4
= y^4 / x^3
answer is D. y^4 / x^3
Answer:
97, 485, 197
Step-by-step explanation:
<u>Given</u>:
- First number = a
- Second number = b
- Third number = c
<u>Then we have:</u>
- b = 5a
- c = 100+a
- a + b + c = 779
<u>Substituting b and c in the third equation:</u>
- a + 5a + 100+a = 779
- 100 + 7a = 779
- 7a = 779- 100
- 7a=679
- a= 679/7
- a = 97
- b= 5*97 = 485
- c = 100+ 97 = 197
Two decimal places to the left or right? If it’s to the right (postitive) then it’s 7037.1 if it’s to the left (negative) then it’s .70371, hope this helped!
