Answer:
Infinitely many solutions.
Step-by-step explanation:
Let's begin by carrying out the indicated multiplications, which must be done before any addition or subtraction:
2(8r+5)-3=4(4r-1)+11 becomes 16r + 10 - 3 = 16r - 4 + 11.
Subtracting 16r from both sides, we get 10 - 3 = - 4 + 11, or 7 = 7
This is always true, so we can conclude that this equation has infinitely many solutions.
Answer:
The temperature needs to decrease by 7°F to return to the original temperature.
Step-by-step explanation:
The temperature starts at 33 degrees then increases by 10 then 12 then decreases by 15 which will equal 40.
33 + 10 = 43
43 + 12 = 55
55 - 15 = 40
40 - 33 = 7
The temperature needs to decrease by 7 degrees.
Circumference of circle = 11.27π ft
so,
C = 2πr
or, 11.27π = 2πr
or, 11.27π/2π = r
so, r = 5.635 ft
now,
diameter = 2r
= 2 x 5.635
= 11.27 ft
Divide 10 by 25, which would get you 4. Move the decimal over two to the left, because you wanted a percentage.
