Answer:
19mph
Step-by-step explanation:
Divide 57 by 3 and you'll get 19mph - the average speed.
(3,6)
4x + y > 19
4(3) + 6 > 19
12 + 6 > 19
18 > 19
No
I can't explain it but if you need me to explain it I can but here is my work.
The value of x from the given expression is 5/6
<h3>Expansion of equation</h3>
Given the expression to expand expressed as:
15 = 3/5(6x + 20)
We are to determine the value of x
15(5) = 3(6x + 20)
Expand
75 = 18x +60
Collect like terms
18x = 75 - 60
18x = 15
x = 15/18
x = 5/6
Hence the value of x from the given expression is 5/6

The perimeter of the square is 28-12n.
We have a square. The length of the side of the square is (-3n + 7). We need to find the perimeter of the square. The perimeter of a shape is defined in geometry as the total length of its boundary. The perimeter of a shape is calculated by adding the lengths of all the sides and edges that surround it. The perimeter of a shape is the sum of all the sides of the shape. The square has four sides, and all the sides of the square are equal to each other. The perimeter of the square is four times the length of one of its sides.
P = 4*(-3n + 7) = -12n + 28
