Answer:
20
Step-by-step explanation:
180 g of flour=18 fingers
180/18= 10
10 g of flour makes 1 finger
10 g of flour × 20 = 20 fingers
Answer:
x=5
Step-by-step explanation:
2 2/7 : (0.6x) :: 4/21 : 0.25
Hence, as it is in a perfect proportion, we may use the proportion method..
We multiply the extreme terms and the moderate(near) ones and equalise them.
Hence,
(2 2/7)×(0.25) = (0.6x × 4/21)
16/7 × 25/100 = 6x/10 × 4/21
16/7× 1/4= 3x/5 × 4/21
(16/7 × 1/4)/(4/21) =3x/5
16/7×1/4×21/4×5/3=x
1/7×21×5/3=x
x=5

Answer:
-5/8
Step-by-step explanation:
So basically with fractions that have different denominators you have to find the GCF (greatest common factor) of both of them, in this case 8 would be a GCF because it you times 4 and 2 you get a whole number of 8. since we found out the GCF we want to set them equal. so take the 1/4 and multiply both the top and bottom by 2, so we end with 2/8. You set the equation back up (-7/8) + (2/8). and combine the numerators -7+2/8 which ends you with with the answer of (-5/8) :)
For this case we have the following functions:
f (x) = 36 + 4x
g (x) = x2 + 15
By matching both functions we have:
f (x) = g (x)
36 + 4x = x2 + 15
Rewriting we have:
x2 + 15 - 4x - 36 = 0
x2 - 4x - 21 = 0
Solving the polynomial we have:
(x-7) (x + 3) = 0
x = -3
x = 7
Taking the positive root we have:
x = 7
