I'm guessing the % of syrup refers to the % of sugar it has, therefore:
50% = 50 / 100 = 0.5
0.5 * x = 0.5
x = 0.5/0.5
x = 1
She will have 1 lbs of syrup

Step-by-step explanation:
q =−1/6
3x6=18 3x4=12 12+18=30 so the actual area is 30
Answer:
Step-by-step explanation:
In each case, the multiplier of x is (1 + fractional change). The fractional change is negative for a discount or draining. It is positive for any addition or increase.
a) (1 -0.18)x = 0.82x . . . . 18% = 0.18
b) (1 +0.18)x = 1.18x
c) (1 -3/10)x = 7/10x
d) (1 +3/10)x = 13/10x
Your answer is gonna be 56
some explanation stuff if needed :
8 questions, and your teacher will choose 5. The order doesn’t matter just whether or not they’re on the test!
Thats a combination (permutation is where the order matters).
nCr= (n!)/(n-r)!·r!
n is the number of options
r is the number you choose
! is “factorial” (multiplying every whole number down the 1; ex: 4! = 4·3·2·1 = 24)
so lets substitute:
n= 8 questions from which to choose
r= 5 the number the teacher will choose
8C5= (8!)/(8-5)!·5!
= (8!)/(3)!·5!
= (8·7·6·5·4·3·2·1)/(3·2·1)·(5·4·3·2·1)
= 40,320/(6)·(120)
= 40,320/720
= 56
There are 56 possible combinations of 5 questions your history teacher could choose.
