Answer:</h3>
- running speed: 8 mph
- walking speed: 2 mph
<h3>
Step-by-step explanation:</h3>
Let w represent Lizette's walking speed. Then her running speed is w+6. The relationship between speed, time, and distance is ...
distance = speed × time
Lizette ran for 1.5 hours, then walked for 3 hours. Her total distance is ...
(w+6)·1.5 + w·3 = 18
4.5w + 9 = 18 . . . . . simplify
4.5w = 9 . . . . . . . . . subtract 9
w = 2 . . . . . . . . . . . .divide by 4.5
Lizette's walking speed is 2 mph; her running speed is 8 mph.
Answer:2
Step-by-step explanation:
DIVIDE 425 ON BOTH SIDES
AND U WILL GET 2
B is the answer how you do good
Area of a triangle is base × height ÷2
base=8x+4 x=-4/8 x=-1/2
height=3x-4 x=4/3
A=b×h÷2
A=(-1/2×4/3)÷2
A=(-4/6)÷2
A=(-4/6)÷2/1 to divide by fractions flip the second and multiply
A=-4/6×1/2
A=-4/12
A=-1/3
Answer:
im not too sure but my best guess would be
D= 900×T
D= the constant of proportionality multiplied by time to get how many miles traveled.
if the hours given were 1 hour 2 hours & 3 hours
if you multiplied them by 900 you would get the distanced traveled
900 x 1 = 900 miles traveled in one hour
900 ×2 = 1800 miles traveled in 2 hours
sounds good ?
