For this case what you can do is an average to calculate the number of hours it will take them to work together:
Let
t: average time.
hi: hours worked for each one.
n: number of teams.
The average will be given by:
t = (h1 + h2) / (n)
Substituting both values:
t = ((15) + (10)) / (2) = 12.5
answer
it would take 12.5 h to pave that same section of highway if both crews worked together
The perimeter of an object is given by the sum of all the sides of the object. Thus the perimeter of a quadrilateral is the sum of the four sides of the quadrilateral.
Given a quadrilateral with sides: n, 2n - 12, 3n + 4, n + 7
The sum is n + 2n - 12 + 3n + 4 + n + 7 = 7n - 1 = 90
Thus, 7n = 90 + 1 = 91 and n = 91 / 7 = 13.
Therefore, the length of the side KL is n = 13 centimeters.
Answer:
that is the solution to the question

Mr. Loomis uses 2.46 gallons of gas
Algebra is a branch of mathematics that uses mathematical expressions to represent problems. Variables such as x, y, and z are combined with mathematical operations such as addition, subtraction, multiplication, and division to
Given that Mr. Loomis owns an SUV with a 24.6-gallon fuel capacity.
He filled the tank and then used exactly one-tenth of the gas on a recent trip.
Do we have to find how many gallons of gas did he use = ?
One-tenth of gas = 1/10
= (1/10)(24.6)
= (24. 6)/ 10
= 2.46
Therefore he uses 2.46 gallons of gas
