Answer:
a = 6
Step-by-Step Explanation:
9 + 8a = 57
8a = 57 - 9 (subtract 9 from both sides)
8a = 48 (then divide 8 from both sides to get "a" alone)
a = 48/8
a = 6
Answer:
Question 3 is true, Question 5 is 2 dollars and 50 cents, Question 7 is 70
Step-by-step explanation:
3:
True because if you multiply the sides you get 9
Length: 3
Width: 3
Height: 1
3x3x1 = 9
5:
10 Dollars
Take 7 dollars and 50 cents away
10-7.5 = 2.5
Therefore you will have 2 dollars and 50 cents received back
7:
14x5
14+14+14+14+14
28+14+14+14
42+14+14
56+14
70
All other questions are correct, hope this helped!
Answer: The system of linear equations are
L + W = 45
L = 4W - 5
Step-by-step explanation:
Let L represent the length of the deck.
Let W represent the width of the deck.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2( length + width)
The perimeter of a rectangular wooden deck is 90 feet. This would be expressed as
90 = 2(L + W)
Dividing through by 2
L + W = 45
The deck's length,L is 5 less than 4 times its width, W. This is expressed as
L = 4W - 5
Hello!
To find the amount of miles a car can drive with one gallon, divide the total miles by the amount of gallons it takes to drive that specific amount of miles.
450 miles / 18 gallons = 25 miles per gallon
Therefore, you can drive 25 miles with one gallon of gas.
