Answer: 
Step-by-step explanation:
Subtract 490 from both sides
Then flip
multiply both sides by
to cancel out 
Thus giving you -735 as your
.
Then you plug it back into the equation to solve.
You cannot add -10y+9x or 10y+5x because of the rule “combine like terms”...
Answer: 57% for the first and 41% for the second
Step-by-step explanation:
Treatment 1 consists of 40 people and 23 had improved health take 23 and divide it by 40 and you get 0.575 multiply that by 100 and you get 57% do the same for the second question and you get 0.416 multiply by 100 and you get 41%
Answer:
12.25 M^2(square) 12.56 M^2(circle)
Step-by-step explanation:
side of square= 3.5 M
area of square garden= side*side
=3.5*3.5
=12.25 M^2
Diameter of circle=4 M
Radius of circle=Diameter/2
=4/2
=2
Area of circle garden= 2(pi)r^2(where r is radius)
=3.14*2*2
=12.56 M^2
Answer:
42x^2 - 7x - 6x + 1
42x^2 - 13x + 1 for FOIL method
To solve for x
7x - 1 = 0
7x = 1
x = 1/7
6x - 1 = 0
6x = 1
x = 1/6
