The cable company charges $30 to install new supplies at your house. Each month the cable bill is $75. What equation models the total cost for cable over time?

Answers

Answer 1
Answer: x is the amount of months
y is the total bill

75x +30 = y

This is because 30 dollars is a one time fee so you will only add it once. 75 dollars is a recurring fee, so you pay it every month. Y is the total cost for cable.

Why is 9 -1is 8 can some one help me because i dont understand why is not 10

Answers

Ah, the dash, this thing, - means subtraction, which is the opposite of addition, and takes away numbers. Meaning 9-1 is 9, but you count down by 1 rather than up one.
Its 8 because your not adding your subtracting.

A part in the whole is called as fractions.

Elisa withdrew $20 at a time from her bank account and withdrew a total of $140.francis withdrew $45 at a time from his bank account and withdrew a total of $270.We need to find who made greater number of withdrawls.

Elisa withdrew $20 at a time from her bank account and withdrew a total of $140.

Number of withdrawls=Total amount withdrawn/Withdrawl amount each time

=140/20

=7

Francis withdrew $45 at a time from her bank account and withdrew a total of $270.

Number of withdrawls=Total amount withdrawn/Withdrawl amount each time.

=270/45

=6

By comparing Elisa and Francis, we find that Elisa withdrawls more time than Francis(7>6).

Therefore Elisa made the greater number of withdrawals.

Elisa made more withdrawals because when you divide Elisa's total withdrawal by the amount of cash she withdrew at a time would be 140/20=7. When you compare that to Francis's withdrawal which would be 270/45=6. 7>6 so Elisa made more withdrawals than Francis.

What multiplication expression can be broken apart into (3x4) + (3x4) using the distributive property

Answers

The original expression here might be (4x3) + (4x3). This is because thedistributive property simply moves around numbers, but will not changethe value of the equation, as in the question we are looking at here.

One possible answer is:

3(8)

Explanation:

The distributive property states that we multiply everything inside parentheses with the term outside parentheses. Algebraically, it is a(b+c) = ab+ac.

This means we need to split 8 up into a sum. Using 4+4, we have 3(8) = 3(4+4) = 3(4) + 3(4)
