Answer:
The answer is: amount of flour used for bread and brownies is same
Step-by-step explanation:
Step 1:
Assume;
Flour used for cookies = x
Flour used for bread = z
Flour used for brownies = y
Flour used for cookies = a
Step 2:
Now, for bread as mentioned flour used for bread is one fourth less than flour used in cookies therefore;
z = x - (1/4)x
z = x-0.25x
z = 0.75x
Step 3:
Now, for cookies as mentioned flour used for cookies is one third more than flour used in brownies therefore;
x = (1/3)y + y
x = 0.33y + y
x = 1.33y
Step 5:
Value of z from step 2:
z = 0.75x
now put value of x from step 3 in above equation;
z= 0.75 (1.33y)
z = (1) y
hence proved;
z = y
Answer:
x = -2 and 1
Step-by-step explanation:
Given :
f(x) = x+2
g(x) = -x²+4
The solution to the equation f(x) = g(x)
=> x+2 = -x²+4
=> x²+x = 4-2
=> x²+x -2 = 0
By factorisation
=> x²+2x-x -2 = 0
=> x(x+2) -1(x+2)
=> (x+2) (x-1)
x = -2 and 1
40 questions. You set up a proportion, mutiply 34 by a 100 and get 3400. Then you divide 3400 by 85 and you get ur answer. You could also try guessing by putting in random values you think are the whole number and multiplying them by 0.85. So if you guess 44 is the whole and try checking it by multiplying it by .85 and get a value thats higher than the value the percentage is equal to you try another smaller value. So if 44 doesn't work you can try 40. 40 times .85 is 34 so your answer of 40 questions is correct.
