Dado que:
Custo total de bolsa e sandália = 74,00
Deixei :
Custo da sandália = x
Custo da bolsa = x - 23
Preço da sandália:
x + (x - 23) = 74
x + x - 23 = 74
2x - 23 = 74
2x = 74 + 23
2x = 97
x = 97/2
x = 48,5
Portanto, custo da sandália, x = 48,5

DONE

Answer: After 13 (12) hours, there would be 6,500 bacteria across the culture.
Step-by-step explanation:
The bacteria grew by 500 each 4 hours, so to know how much there would be 13 hours later:
Simple, add 500 bacteria to every 4 hours until you reach 13 hours. 4 = 5.5k, 8 = 6k, 12 = 6.5k. Now, 12 is closer to 13 than anything we would've gotten if we kept going.

The total height of 4 building blocks and a flagpole on top is 23 cm.
The total height of 9 building blocks and a flagpole on top is 43 cm.
Find the height of a building block and the height of a flagpole.
Height of a building block =
cm
Height of a flagpole =
cm
Answer:
building block = 4cm
flag pole = 7 cm
Step-by-step explanation:
9b + f = 43
4b + f = 23
5b = 20
b = 4
16 + f = 23
23 - 16 = 7
f= 7
36 + 7 = 43

A book has a front and a back and 200 pages.
The front and back cover are each 0.7 mm thick, measured to 1 decimal place.
Each page is 0.14 mm thick, measured to two decimal places.
Calculate the minimum thickness of the book.
Some working must be shown.
Answer:
28.3mm
Step-by-step explanation:
upper bound of front and back cover=0.75mm and lower bound=0.65mm
lower bound of page=0.135mm and upper bound=0.145mm
As there is a front and back cover we multiply the lower bound by 2
as there is 200 pages we multiply the lower bound by 200
(0.65*2)+(0.135*200)=28.3mm
The minimum thickness of the book will be 29.4 mm.
What is decimal place?A decimal point divides a decimal number into a whole number and a fractional component. The dot that appears between the whole number and the fractions is the decimal point.
The Upper and lower cover thickness are both 0.7 mm, respectively.
The Upper and lower thickness of the page are both 1.4 millimeters
We multiply the page thickness by two because there is a front and back cover. The page thickness is multiplied by 200 because there are 200 pages.
(0.7*2)+(0.14*200) = 29.4mm
Therefore, the thickness of the given book can not be smaller than 29.4 mm or 2.94 cm

2.) 15x18+12/3+9
Answer:
283
Step-by-step explanation:
15(18) + 12/3 + 9
270 + 4 + 9 = 283
Answer:
283
Step-by-step explanation:
First, we have the equation 15 × 18 + 12/3 + 9.
If we refer to PEMDAS, division comes first, then multiplication, addition, and subtraction.
So, the equation becomes 15 × 18 + 4 + 9.
Now, we can multiply 15 × 18 in the equation.
The equation becomes 270 + 4 + 9.
4 + 9 = 13.
270 + 13 = 283.
Indicate below whether the equation in the box is true or false 1/6 = to 6/12

inches. When TV's are advertised the size listed is the
diagonal length. What would be the advertised size of
this TV?
Answer:
85 inches
Step-by-step explanation:
