Answer:
-0.5 is not a solution
2 is a solution
Step-by-step explanation:
To check if something is a solution of the equation, you need to substitute the value in place of the variable
15 + 2y = -12 - 4y
15 + 2(-0.5) = -12 - 4(-0.5)
15 - 1 = -12 + 2
14 ≠ -10 ∴ -0.5 is not a solution
5 - 2(3x + 5) = 3 - 10x
5 - 2[3(2) + 5] = 3 - 10(2)
5 - 2(6 + 5) = 3 - 10(2)
5 - 12 - 10 = 3 - 120
-17 = -17 ∴ 2 is a solution
Answer:
80 feet.
Step-by-step explanation:
Given:
The length of a rectangular garden is 10 yards and its width is 10 feet.
To find:
Perimeter of the garden in feet ?
Solution:
Length = 10 yards
1 yard = 3 feet
10 yards = 3 
10 = 30 feet
Breadth = 10 feet
Now, as we know:
Hence, the perimeter of the garden is 80 feet.
6+1/343+36+1/81−27−36+1/81-27-243+1/256+1/144+1/8+1/5
Using
f1(x)= -x=3t =14
with f2(x) as x=4y
f1(f2)= -x-3y=14
F1(4y)= -(4y)-3y=14
= -4y-3y=14
= - 7y=14
= y= -2
Using the value of y, solve fo rx by entering the value in the original form of f1 or f2
<span>-x-3y=14</span>
-x-3(-2)=14
-x+6=14
x=-8
OR
x=4y
=4(-2)
= -8
Thus the solution is (x,y) = (-8,-2)
