The perimeter of a playing field for a certain sport is 214 ft. The field is a rectangle, and the length is 41 ft longer than th

Shtirlitz [24]

Answer:

width: 33 ft

length: 74 ft

Step-by-step explanation:

The perimeter of a rectangle is calculated by adding all of the sides together which includes two lengths and two widths. Since the formula for the length is given (l = 41ft + w) and the perimeter is given, then we can simply use the perimeter formula and substitute the value of length with its formula which would only leave us with one variable in the equation w. Now we must solve for w.

l + l + w + w = 214

(41 + w) + (41 +w) + w + w = 214 ... combine like terms

82 + 4w = 214 ... subtract 82 from both sides

4w = 132 ... divide both sides by 4

w = 33 ft

Finally, we can see that the value of the width is 33 ft . Now we plug this value into the formula for length to calculate its value.

l = 41 + w

l = 41 + 33

l = 74 ft

The LCM of two numbers is 36 their GCD is 3 one of the number is 9 find the other number

Aleks04 [339]

Answer:

Step-by-step explanation:

The LCM of 9 and x = 36

The GCD is 3, that means the number has to be divisible by 3 as well.

We can look at all the factors of 36, and see which numbers fit the description

36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

1: Does not have a GCD of 3

2: Does not have a GCD of 3

3: Has a GCD of 9, but LCM is 3, not 36

4: Does not have a GCD of 3

6: Has a GCD of 3, but LCM is 18, not 36

9: Number is given

12: Has GCD of 3, and LCM is 36

18: Has GCD of 9

36: Has GCD of 9

The only number that works is 12, with a GCD of 3, and an LCM of 36

Quiero realizar ese ejercicio 10x + 8 = 2 - 2x

olasank [31]

Answer:

x=-1/2

Step-by-step explanation:

Move -2x to the other side by adding 2x on both sides:

12x+8=2

Move 8 to the other side by subtracting by 8 on both sides:

12x=-6

Divide by 12 on both sides:

x=-1/2

Hope this helps!
