Answer:
Her account balance will be $2,080 at the end of the year
Step-by-step explanation:
Let
y ----> Susannah's account balance
x ---> is the amount of time in months
we have

This is a linear equation in slope intercept form
where
The slope or unit rate is equal to

The y-intercept or initial value is equal to

Remember that
One year is equal to 12 months
so
For x=12 months
substitute in the linear equation

Answer:
like terms: (3n,-n),(7,-3)
Step-by-step explanation:
Answer:
let the total number of students bex
Then
10%of x=1120
or,(10/100)x=1120
or,x/10=1120
or,x=11200
The total no. of students is 111200
To find the length of the hypotenuse we must use Pythagoras' Theorem: c^2 = a^2 + b^2, where c is the hypotenuse and a and b are side lengths
c^2 = a^2 + b^2
c^2 = 12^2 + 35^2
c^2 = 144 + 1225
c^2 = 1369
c = 37 cm
