<u>Answer:4.75</u>
<u>Since we don't have a total cost we will write an equation that will allow us to find the cost of x. The equation is 4x= 2x + $3 + $3.75 + $2.75. Now that we have our equation we are going to start by adding 3, 3.75, and 2.75. When added together, they come out with a total of 9.5. Now the equation becomes 4x= 2x + $9.50. Since we have our new equation we are going to subtract 2x from both sides of the equation. We now have the equation 2x= $9.50. Finally, you will divide both sides by 2. This leaves us with the final outcome x= $4.75. This means that one glues stick cost $4.75. Let's check by substituting $4.75 as the value of x in the expressions 4x is Carlo's total and 2x + $3 + $3.75 + $2.75 is Helen's total. First we do 4x, 4 multiplied by 4.75 equals 19, so Carlo spent $19 on art supplies. Now we do 2x + $3 + $3.75 + $2.75, which is 9.5 added to 9.5 and equals 19. So Helen spent $19 on art supplies. This proves that the cost of one glue stick, x, is equal $4.75.</u>

Answer:
58.3
Step-by-step explanation:
58.3 has the highest unit (the number left of the dot)
Step-by-step explanation:
the integer that represents the opposite of a gain of 400 = - 400
The answer is is 12.
You can calculate this by multiplying the whole number (in this case, 48) with the percentage (in this case, 25%.)
You would multiply them like this:
48 times 0.25
You put the 0. In the front of the 25 because this is a fraction and a percent.
Hope that helps!!!
Answer:
![L(t) = 1,100*(1+0.87)^{\frac{t}{2.4}}](https://tex.z-dn.net/?f=L%28t%29%20%3D%201%2C100%2A%281%2B0.87%29%5E%7B%5Cfrac%7Bt%7D%7B2.4%7D%7D)
Step-by-step explanation:
The locust population grows according to an exponential model with the following general formula:
![L(t) = L_0*(1+r)^{\frac{t}{T}}](https://tex.z-dn.net/?f=L%28t%29%20%3D%20L_0%2A%281%2Br%29%5E%7B%5Cfrac%7Bt%7D%7BT%7D%7D)
Where 'L0' is the initial locust population, 'r' is the increase rate after 'T' days, and 't' is the time passed, in days.
Applying the given data, the function that models the locust population t days since the first day of spring is:
![L(t) = 1,100*(1+0.87)^{\frac{t}{2.4}}](https://tex.z-dn.net/?f=L%28t%29%20%3D%201%2C100%2A%281%2B0.87%29%5E%7B%5Cfrac%7Bt%7D%7B2.4%7D%7D)
