For this case you can solve the problem by applying a simple rule of three in which we have
520 ---> 100%
800 ---> x
Clearing x we have
x = (800/520) * 100 = 154%
the percentage increase in cost was
154-100 = 54%
answer
the percentage increase in cost was 54%
Answer:
Step-by-step explanation:
Slope m is defined as m=(y2-y1)/(x2-x1) in this case
m=(218-155)/(22-15)=63/7=9
y=mx+b
y=9x+b, using point (15,155) we can solve for the y intercept b
155=9(15)+b
155=135+b, b=20 so the line is
y=9x+20
In thirty days there will be
y=9(30)+20=290 coins
11 - 3x < 53
First, subtract 11 from both sides.
-3x < 42
Then divide -3 by both sides, and switch the sign.
x > -14
The answer to the first question is
(5x + 6) (8x^2 + 7) and the second question’s answer is 4x^2(x + 1)(x + 5)
Answer:
Ans is option c
Step-by-step explanation:
Opposite angle in a parallelogram are equal. 3n+20 = 6n-25. n=15. You then plug n in into the equations. B=65 and D=65
