Answer: 1/4x + 1/2x = 12
x = 16
Step-by-step explanation: combine the 1/4x and 1/2x to 3/4x because they are like terms then divide 12 by 3/4 or 0.75 to get 16
The required number is 16.
What is equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, one quarter of a number increased by one half of the same number is twelve,
We will solve this question by setting an equation,
Let the number be x,
Therefore, establishing the equation,
x/4 + x/2 = 12
3x/4 = 12
x = 16
Hence, the required number is 16.

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
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]

What is the final elevation if a. A bird starts at 20 m and changes 16m? b. A butterfly starts at 20 m and changes -16m? c. A diver starts at 5 m and changes -16m? d. A whale starts at -9 m and changes 11 m? e. A fish starts at -9 meters and changes -11 meters?
Answer:
A.36m
C.-11m
D.2m
E.20m
Step-by-step explanation:
Sorry I forgot b
The final elevation of the given animals is as follows 1)Bird = 36m 2) butterfly = 4m 3) diver = -11m below sea level 4) whale = 2m 5) fish= -20 m
What is the rule for summing positive and negative numbers?To get the sum of a negative and a positive number, use the sign of the larger number and subtract. For example: (–7) + 4 = –3. 6 + (–9) = –3.
Given here,1) A bird starts at 20 m and changes 16m in a positive direction therefore net elevation is 20 + 16 = 36m
2) A butterfly starts at 20 m and changes -16m, thus again net elevation is
20-16 = 4m
3) A diver starts at 5 m and changes -16m, the net depth of the diver below sea level is 5+(-16) = -11m
4) A whale starts at -9 m and changes 11 m in the positive direction then net depth is -9+11 = 2m
5) A fish starts at -9 meters and changes -11 meters in the negative direction thus net depth is = 9-11= -20m below sea level
Hence these are the final answers.

Segment AB measures 3 cm. Point O is the center of dilation. How long is the image of AB after a dilation with . . .
Use decimal notation if necessary.
a. scale factor 5?
Answer:
The image of AB will be 15 cm long after dilation by a scale factor of 5.
Step-by-step explanation:
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruentRule to calculate the mage of the segment AB after dilation of the segment AB by a scale factor 5 centered at the origin
AB = length → A'B' = 5(length)
It means the length of the image of the segment AB can be determined by multiplying the length of the original segment AB by 5.
so
AB = 3 cm
Thus, the length of image A'B' will be:
A'B' = 5(3) = 15 cm
Therefore, the image of AB will be 15 cm long after dilation by a scale factor of 5.

The area of a rectangular outdoor stage has been extended on one side. The entire new area in square meters can be written as 216+12x. Factor the expression to find the dimensions of the extended stage.
PLZ HELP
Answer:
Dimension of the extended stage is; length = 6 m and width = 2x m
Step-by-step explanation:
Area of the rectangular outdoor = length x width
New area = area of the outdoor + area of the extended stage
= 216 + 12x
= 6(36 + 2x)
New area = 6 (36 + 2x)
So that;
The dimension of the rectangular outdoor = 36 x 6
i.e length = 36 m and width = 6 m
So that the dimension of the extended stage = length x width
= (6 x 2x) m
i.e length = 6 m and width = 2x m
