A magazine costs $3 and a book cost $7 if you want to spend exactly $45 on reading this month and you need to buy eight magazines how many books can you buy write an equation in standard form modeling the situation then see how many books you can buy let em represent the number of magazines you buy and B represents the number of books you buy.
Answer:
m = 8 and b = 3 OR m = 15 and b = 0
Step-by-step explanation:
Note that the conditions on this problem could be contradictory (they are likely not, but could be)
let m be the number of magazines bought
let b be the number of books, then
3m is the cost of the magazines bought and
7b is the cost of the books bought, since $45 exactly must be spent then
3m + 7b = 45
Let us assume m = 8 and see what happens
3(8)+7b = 45
24+7b=45
7b=21
b=3, this meets the requirements and results in an integer (whole) number of books, if b had ended up as a fraction, then m=8 would have to be wrong and we would have tried m=9 , then 10, 11, 12, up to 15 if necessary until we got a whole number of books. Notice that 15 magazines and 0 books also works

Answer:
-7 > -10
Step-by-step explanation:
We just have to compare these two numbers. When you're comparing two negative numbers, the smaller number is the bigger one. Ex. -3 is bigger than -6, so we can say that -3 > -6 (-3 is greater than -6). This means that -7 is larger than -10, which allows you to say that -7 > -10.

Given this number line, DB = [?]
The required measure of the number line DB = 6.
GIven that,
A figure of number line shown, and a number has been marked on the number line A = 4, B = 7, C = 11, and D = 13
The measure of DB is to be determined.
A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
since
On the given number line, marked from 4 to 13 or from A to D,
Total length AD = 9, which implies the line is distributed in 9 equal parts from 4 to 13.
Now measure of DB = AB - AD
= 13 - 7
= 6
Implies that there are equal parts of the line in DB.
Thus, The required measure of the number line DB = 6.

a map is drawn in the scale of 1:500000. the area of a pond on the actual ground is 100km^2. find the area on the map in square centimetres that represents the pond
Answer:
2 000 000 [tex]cm^{2}[/tex]
Step-by-step explanation:
100 [tex]km^{2}[/tex] = 1 000 000 000 000 [tex]cm^{2}[/tex]
the scale of 1:500000 means that 1 cm in the map represents 500000 cm in reality
So on the map this pond's area would be
[tex]\frac{1 000 000 000 000}{500000}[/tex] = 2 000 000 [tex]cm^{2}[/tex]
