length of a rectangle is 6 less than 3 times its width"
L = 3W-6
"perimeter of the rectangle is 148 meters"
2L + 2W = 148
L + W = 74
(3W-6) + W = 74
4W = 80
W = 20 m
L = 3W-6 = 54 m
Answer:
x=y-48, y=x+48
Step-by-step explanation:
Answer:
3. 9x+5+x-7=25
4. 10x-2=25
5. 10x=27
Step-by-step explanation:
3. 9x+5+x-7=25
4. 10x-2=25
10x=25+2
5. 10x=27
x=27÷10
x=2.7
Answer is option 4. working out attached

By using simple rule of three, a period of 9.5 years on Venus is equivalent to 2134.65 terrestrial days.
<h3>How many terrestrial days are equivalent time in Venus?</h3>
One year on Earth is equivalent to 365.3 days and one year on Venus is equivalent to 224.7 days, the equivalent terrestrial time of 9.5 years on Venus is found by simple rule of three:
x = 9.5 yr × (224.7 days / 1 yr)
x = 2134.65 days
A period of 9.5 years on Venus is equivalent to 2134.65 terrestrial days.
