The answer is: [D]: " 24 + 2w " .
___________________________________________
Explanation:
___________________________________________
Given: The formula for the Perimeter of a rectangle:
___________________________________________
P = 2L + 2w ;

in which:
P = perimeter ;
L = length = 12 units (given);
w = width = unknown;
_______________________________________________________
Find the perimeter, "P", in terms of "w" ; since "w" (width) is unknown; and considering the answer choices given; along with the information provided in the problem, we only have enough information to solve for the perimeter, "P", in terms of "w" ;
_____________________________________________________
So, given the formula/equation for the perimeter, "P" :
_____________________________________________________
P = 2L + 2w ; we know that: " L = 12 units " ;
_____________________________________________________
P = 2*12 + 2w = 24 + 2w ; which is: "Answer choice: [D]" .

Answer:

x = 4

Step-by-step explanation:

180° - 114° = 66°

15x - 6 = 66

15(4) - 6 = 66

60 - 6 = 54

Statement is wrong because we can see another angle. so...

Final answers: x = 4 while 54 + 114° = 168° then 180° - 168° = 12°

Answer:

C) 5.5 h

Step-by-step explanation:

Plug in the values

253.55 = 46.1 * t

Answer:

900

Step-by-step explanation:

The ratio of the number of people who own a smartphone to the number of people who a flip phone is 5:3.

Let the number of people who own a flip phone=x

If 600 more people own a smartphone than a flip phone, then the number of people who own a smartphone=x+600

To find x, we express the ratio and population as an equality.

5:3=x+600:x

Expressing the ratios as fractions would give:

$\dfrac{5}{3}=\dfrac{x+600}{x}$

Next, we cross multiply

5x=3(x+600)

Open the brackets by expansion.

5x=3x+(3 X 600)

5x=3x+1800

Subtract 3x from both sides.

5x-3x=3x-3x+1800

2x=1800

Divide both sides by 2

x=900.

Since x=900, the number of people who own a flip phone is 900.

25 gallons of gas were pumped into two different size tanks. Express the amount of gas pumped into the smaller tank in terms of

ioda

Answer:

The expression of amount of gas is $s=25-g.$

Step-by-step explanation:

Given:

25 gallons of gas were pumped into two different size tanks.

Now, to express the amount of gas pumped into the smaller tank in terms of the amount $g$ pumped into the larger tank.

Let the amount of gas pumped into smaller tank be $s.$

And according to question, the amount of gas pumped into larger tank is $g$ .

Total amount of gas pumped into both size tanks = 25 gallons.

So, to express the amount of gas pumped into the smaller tank in terms of the amount $g$ pumped into the larger tank:

$s+g=25$

Subtracting both sides by $g$ we get:

$s=25-g.$

Therefore, the expression of amount of gas is $s=25-g.$
