Answer:
see below
Step-by-step explanation:
The expression for the account is
a) 3600 -400M where m is the number of months
b) We want the expression to equal 2000
3600 -400M = 2000
c) 3600 is the initial amount in the account
400 is the amount that the account goes down each month
M is the number of months
2000 is the amount left in the account
Step-by-step explanation:
∠4 = ∠1 & ∠2 = ∠3
360 - 2(98) = ∠2 + ∠3
∠3 = 164/2
∠3 = 82°
Answer:
x = 9
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
( cross- multiply )
12(x - 1) = 96 ( divide both sides by 12 )
x - 1 - 8 ( add 1 to both sides )
x = 9
As a fraction, it can’t be simplified. As a decimal, it’s 0.375.
