Answer:
Since the scale is 1:5.
Therefore Actual height is five times Model
3.If model length is 6ft then actual length is 30 ft
4 If actial depth is 20 ft then model depth is 4 ft
5 If actual diameter is2 ft then model diameter id 0.4ft.
So set it equal to 0... add the 2 and divide by -4
Answer:
Account balance is not proportional to the number of weeks.
Step-by-step explanation:
Initially Adrian's saving account balance was = $28
He deposits $15 in his account each week.
If we denote week with a variable 'x' then after 'x' weeks total amount in is account = $15x
So, total amount in his account after 'x' week will be;
y = 15x + 28
It's a linear equation representing total amount after 'x' weeks with a constant growth rate of 15 and initial amount 28.
In other words equation is in the form of y = mx +b.
This equation doesn't show the proportional relation because equation in the form of y = kx represents the relation of proportionality only.
Distribute then add
a(b-c)=ab-ac
-2.5(1 -2n) - 1.5n
-2.5(1-2n)= -2.5-(-5n)=-2.5+5n
now add the other bit
-2.5+5n-1.5n
-2.5+3.5n
B is a corect answer
find others
distribute and add last 2 choices
D=-2.5-3.5n
E=-2.5+3.5n
E is correc
t
answers to pick are B and E
