Answer: The length of the rectangle is 15 inches
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The perimeter of a rectangle is expressed as 2 length + 2 width
Perimeter = 2(L + W)
The rectangle has a perimeter of 52 inches. It means that
2(L + W) = 52
L + W = 52/2 = 26 - - - - - - - 1
The length of the rectangle is 4 inches more than its width. It means that
L = W + 4
Substituting L = W + 4 into equation 1, it becomes
W + 4 + W = 26
2W = 26 - 4 = 22
W = 22/2 = 11
L = W + 4 = 11 + 4 = 15
I) 4 Gallons
II) $77
Step-by-step explanation:
30km 1 gallon
420km ?
420 ÷ 30 = 14
? = 40
So, 4 gallons more will be needed to complete the journey.
1 gallon $5.50
14 gallon $?
14 x $5.50 = $77
The cost of the petrol is $77
He bikes 15 miles which is 10 times more than he swims. He runs 9 miles which is half of what he bikes 15/2=7.5. Plus the addition 1.5 miles which is 9. He swims .10 of what he bikes which is 15x.10 which is 1.5 . So he swims 1.5 miles.
Bikes = 15 miles
Run= 9 miles
Swim= 1.5 miles
Add all of them and you get 25.5 which the total amount of miles for his training that day.
Answer:
Step-by-step explanation:
Mean: You just add them altogether then divide the sum by how many numbers there are
Median: You put all the numbers from least to greatest then cross one off on the left and do the same on the right and repeat until there is either one or two numbers left if there are two number then you find the mean of those two numbers, but if you only have one number left then that is your answer
Mode: You find which number is the most common for enstance if there are two 3 and one 4 then 3 would be your answer because there are more 3 than 4
Range: You take the highest number and the lowest number of the set and subtract them and then you have your answer
Answer:
x≥7
Step-by-step explanation:
6(x-3)/8≥3
Multiply each side by 8/6
8/6*6(x-3)/8≥3*8/6
(x-3)≥4
Add 3 to each side
x-3+3≥4+3
x≥7
