Answer:

Speed of car (M) = 65 Unit/hour

Step-by-step explanation:

Given:

Speed equation;

455 = Mx

Time taken (x) = 7 hours

Find:

Speed of car (M)

Computation:

455 = Mx

455 = M(7)

Speed of car (M) = 65 Unit/hour

Can I get step by step help on numbers 52,54,60, and 64 please
Korolek [52]

Answer:

52: 8-Z

54: 18+X

60: 12.3

64: 2.5

52: 8 subtracted from z, the equation will only be 8-z because we do not know what z is.

54: 18 more than a number, we do not know what the number is so we will name it X, more than is adding, so the equation will look like this, 18+X

60: Since y is 6.7, all you have to do is subtract 19-6.7.

64: Since n is 7.5 just divide 7.5 from 3 and you will get 2.5.

Jean bought a $1,980 snow thrower on the installment plan. The installment agreement included a 10% down payment and 18 monthly
Effectus [21]

<u>Solution-</u>

The price of the snow thrower = $1980

He must pay a 10% down-payment and the rest at a $116 monthly payment for 18 months.

<u>A. How much is the down payment</u>

Down payment amount is, 10% of $1980, i.e

=1980\times \dfrac{10}{100}=\dfrac{1980}{10}=\$198

<u>B. What is the total amount of the monthly payments</u>

A monthly payment of $116 for 18 months, i.e

=116\times 18=\$2088

<u>C. How much did Jean pay for the snow thrower on the installment plan</u>

It is the sum of down-payment and total monthly payments, i.e

=198+2088=\$2286

<u>D. What is the total finance charge</u>

It the difference between the original price and the amount paid by Jean, i.e

=2286-1980=\$306

<u> E. If Jean models her payment plan as an arithmetic sequence, give the first term a1 and the common ratio d</u>

As he paid the down-payment of $198 and then a constant monthly payment of $116, so

The first term = 198

common difference = 116

The A.P. series will be, 198, 314, 430, 546, 662,.................., 2286

Confusing stuff! Giving out 50 big points!

If the gum costs 75 cents today, which is 3 cents less than three times what the pack cost 20 years ago, we just need to arrange what we know into an equation.
We know that the price of gum today is 75 cents, so we can leave that on one side of the equation as a constant. Also, since we are dealing only with cents and not dollars, there is no need to shift the decimal point to the left.

? = 75

Now, we can work the equation.

The problem tells us that 75 is 3 cents less than three times the old cost. So, if x is the old cost, we can work out the equation based on that.
It says that it's 3 cents less than 3 times x. The question is basically the equation in word form.

3x - 3 = 75

'3x' being the "three times the old cost" part, '- 3' being the "3 cents less" part, and '75' of course being the current price of a pack of gum.
Option C is your correct answer.

BTW if we were to solve this, we would see that the old price of a pack of gum is:

3x - 3 = 75
   + 3      + 3

3x = 78
/3      /3

x = 26

20 years ago, a 75-cent pack of gum cost 26 cents.
Hope that helped! =)

MrRa [10]

Answer:

Below

Step-by-step explanation:

Sale price of each tire : $92.99 - $20 = 72.99. The cost of x tires is 72.99x

If the sales tax is 4% there is an additional (72.99x)(1.04)

Here is the equation

= (72.99)(1.04) t

If Patrick bought 8 tires.....

= (72.99)(1.04)(8)

= $607.2768

Hope this helps!
