Answer:
8 hours
Step-by-step explanation:
The equation is 2.25X + 3.50 = 21.50
X represents the unknown amount of hours she worked. 2.25 is the cost per hour. 3.50 is the fee she charges for every gig. That fee only happens once a gig so naturally it wasn't the number x was placed with.
2.25X + 3.50 = 21.50
2.25X + 3.50 - 3.50 = 21.50 - 3.50
2.25X = 18
<u>2.25X</u> = <u>1</u><u>8</u>
2.25 2.25
X = 8
The answer is y=-9
negative 9 remember that
Move the constant to the right-hand side and change its sign and calculate
ALGEBRA M8 SOZ
Length = L, Width = W
L = 20 + 2W,
2L + 2W = 610.
then u gotta do some inspiring expression-algebra-maths stuff to work it out :)
the value of x is 5 feets and p = 2, q = 6 and r = 16.
What is a rectangle?
Rectangles are quadrilaterals having four right angles in the Euclidean plane of geometry. Various definitions include an equiangular quadrilateral,
Area of rectangle is A = a*b
Perimeter = 2(a+b)
given in the question that the perimeter is 16 feet.
p= 2(3+x)
p = 6+2x
p = 2
q = 6
r = 16
2x = 10
x =5 feet.
Hence, the value of x is 5 feets.

Answer:

Step-by-step explanation:
The formula of an area of a rectangle:

<em>l</em><em> - length</em>
<em>w</em><em> - width</em>
We have

Substitute:

Use FOIL <em>(a + b)(c + d) = ac + ad + bc + bd</em>
<em></em>
<em></em>
