Answer:
X = 0, Y= -2
Step-by-step explanation:
Compare the x and y coordinate values
3x + 2y =-4_______(1)
2x - y = 2 ________(2)
Multiply the (2) with 2
4x - 2y = 4
and add the new equation to (1)
3x + 2y =-4
4x - 2y = 4
____________
7x = 0
X = 0
Substitute x value into (1)
3 *0 + 2y = -4
0 + 2y =-4
2y =-4
Y= -2
Answer:
$989.23
Step-by-step explanation:
The cost will be the product of the area in square feet and the cost per square foot.
The area of a trapezoid is given by the formula ...
... A = (1/2)(b1 +b2)h . . . . . where b1 and b2 are the base lengths, h is the height
Filling in the given information, the area is ...
... A = (1/2)(73 ft +114 ft)(46 ft) = 4301 ft²
Since each square foot costs $0.23, this number of square feet will cost ...
... (4301 ft²)×$0.23/ft² = $989.23
The landscaper will charge $989.23 to put sod on the backyard.
Since 150 is the total and 12 is per week you can actuality do this equation
T= Total,150$ W=Amount saved,12$
150=12*X or 150/12=X
While X = 12.5 Weeks So, the correct answer
is 12.5 Weeks it can be stated As,
12 weeks 3 days 12 hours (X=12.5)
