Hello there, and thank you for posting your question here on brainly.
Short answer: 280 miles.
Why?
You can find this out by finding out how much 1 in is by dividing 200 by 5. (200 / 5 ==> 40) So 1 in = 40 miles. Now, we multiply that by 7, so we can find out how much 7 in would be. (7 * 4 ==> 280) 7 inches on the map represents 280 miles.
Hope this helped you! ♥
Answer:
(a)Jacob: 256 dandelions
(b)Jessica: 256 dandelions
Step-by-step explanation:
Jacob discovers that the growth over t weeks can be defined by the function:
Jessica finds that the growth function over t weeks is defined by the function:
After 5 weeks:
Number of Jacob's dandelions
Similarly,
Number of Jessica's Dandelions
After 5 weeks, Jacob and Jessica will have an equal number(256) of Dandelions.
Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
Step-by-step explanation:
