A:

-mk - 90 > 85

-mk - 90 + 90 > 85 + 90

-mk > 175

-mk / k > 175 / k

-m > 175/k

-m * -1 < 175/k * -1

m < -175/k


Part B:

3c - 5f = 55

3c - 5f - 3c = 55 - 3c

-5f = 55 - 3c

-5f/5 = (55 - 3c) / 5

-f = 55/5 - 3c/5

Jacky read at the rate of 15 pages per hour. Johnny read at the rate of 1/3 of a pages per minute. Who was reading faster? By ho
o-na [289]
We can compare by converting Johnny's reading time into the same unit of Jacky's, hours.

There are 60 minutes in an hour, so use this:

\frac{1}{3} *  \frac{60}{1} = 20

15 < 20, so Johnny read faster. This is 5 pages faster per hour than Jacky.

8 more than a number
Anuta_ua [19.1K]

Answer:

\boxed{ 8 + x}

Step-by-step explanation:

<em>Hey there!</em>

<em />

In most cases "the number" would be x.

So if the statement says 8 <u><em>"more than a number",</em></u>

It is saying 8 plus x or 8 + x.

<em>Hope this helps :)</em>

Question 1: h+4= how many kids in history class.
I think this cause it says to represent the # of kids in the English class with the varible h. there are 4 more kids in the history class for you just add four to the English class( h). this may be wrong tho

question 2: 57+4= 61.

you just input the 57 where the h (# of kids in English class) cause it need to figure out how many are in history and their are just four more kids. I think


also sorry if I suck at explaining things, this makes sorta sense

The Rule of 72 is a useful approximation for many interest rates and periods for the time it takes a lump sum to double in value
iren2701 [21]

Answer:

The number of years to double the lump sum in value is;

N = 72/10 = 7.20

N = 7.20 years

Step-by-step explanation:

Using the rule of 72 for the approximation:

The formula for rule of 72 is;

Number of years to double = 72/interest rate in percentage

Given;

Interest rate = 10%

The number of years to double the lump sum in value is;

N = 72/10 = 7.20

N = 7.20 years
