Answer:
Step-by-step explanation:
gs used in 180 mile=10 gallons
gas used in 1 mile=10/180=1/18
gas used in 450 mile=1/18×450=25 gallons
Answer:
8÷(x+3)
Step-by-step explanation:
it doesnt specify what number you add with 3 so you substitute it with a variable such as x.
The sum is adding so x +3 and then divide by 8
Answer:
Step-by-step explanation:
The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of the 2 parallel sides or bases of the trapezoid. Since it is an isosceles trapezoid, then the length of the 2 legs are equal.
h represents the height of the trapezoid.
From the information given,
Area = 45cm²
h = 5 cm
45 = 1/2(a + b)5
2 × 45 = 5(a + b)
90 = 5(a + b)
a + b = 90/5 = 18
if one of the legs is 2/3 of the sum of the bases, it means that the height of each leg is
2/3 × 18 = 12 cm
The length of both legs is
12 × 2 = 24 cm
The perimeter of the trapezoid is
Sum of bases + sum of legs
Therefore,
Perimeter = 18 + 24 = 42 cm
Sorry I don't know I'm not that good at these kinds of things so so so sorry
Answer:
6u - 15/2 inches
Step-by-step explanation:
(2/3)rope = 4u - 5
multiply both sides by 3/2
rope = 6u - 15/2
