Iodine test for starch
Method:
Place one spatula of the food sample on a dish or 1 cm3 if the sample is liquid.
Using a dropper, place a few drops of iodine solution onto the food.
Record any change in the colour of the solution.
Starch is detected using iodine solution. This turns blue-black in the presence of starch.
Answer:
x is 7, y is -1
Step-by-step explanation:
x+7y=0
2x-8y=22 -> divide both sides by -2
x+7y=0
-x+4y=-11
Eliminate one of the equations by adding the equations.
11y=-11
y=-1
Substitue the value of y into te equation
x+7*(-1)=0
x=7
Answer:
$809.32
Step-by-step explanation:
The loan amount is 80% of $150,000, or $120,000. The monthly payment of principal and interest is $586.82.
The total annual expense for taxes and insurance is $1920 +750 = $2670, so the monthly expense is $2670/12 = $222.50.
Then the total of payments for mortgage and escrow will be ...
$586.82 +222.50 = $809.32
__
The monthly P&I payment is given by ...
A = P(i/12)/(1 -(1 +i/12)^(-12t)) . . . . . where i is the annual interest rate, t is the number of years, and P is the amount financed.
A = $120,000(0.042/12)/(1 -(1 +0.042/12)^(-12·30)) ≈ $586.82
__
A spreadsheet or financial calculator can be useful for calculating payments, though the formula isn't difficult to use.

(AB)=100
ABC+CBD=100
4x+2+3x-7=100
7x-5=100
7x=100+5
x=105/7
x=15
(CBD) =3x-7
