Answer:
10000000000000000000000000
Step-by-step explanation:
<span>Tripling both dimensions would NOT triple the surface area. If you triple both dimensions, then the surface area is 9 times as long as the surface area of original cone.</span>
The answer for the exercise shown above is the first option (Option A), which is: <span>A. Jamie has $8, and she pays $2 per day to ride the bus.
The explanation is shown below:
If you write the values given in the graph in a table, you can notice that the money decreases on each day. This means that the person does not earn money, but pays. On day zero (0), the person has $8 and then that person pays $2 per day. Therefore, the option A is the answer.</span>
Given:
In a number, adding 
, then multiplying the result by 
we get 8.
To find:
The unknown number.
Solution:
Let the unknown number be x.
According to the question,
Multiply both sides by 
.
Subtract 
from both sides.
Therefore, the required number is 
.
To solve this problem, we must set up a system of equations. In this case, let's let Maggie's age be represented by the variable m and her brother's age be represented by the variable b. We are told that the sum of their ages is 24, which gives us our first equation: m + b = 24. We can construct our next equation from the first sentence of given information: b = 2m - 3. This makes our system of equations:
m + b = 24
b = 2m - 3
To solve, we are going to substitute the value for b in terms of m given by the second equation into the first equation for the variable b.
m + b = 24
m + 2m - 3 = 24
To simplify, we must first combine the variable terms on the left side of the equation using addition.
3m - 3 = 24
Next, we should add 3 to both sides of the equation to get the variable term alone on the left side of the equation.
3m = 27
Finally, we should divide both sides by 3 in order to get the variable m alone.
m = 9
Therefore, Maggie is 9 years old (using the first equation and substituting in this value you can find that her brother is 15 years old).
Hope this helps!
