I dont know actually but you can Google it
Answer:
I think the answer should be B
Answer:
Therefore, Miranda can register for at most 3 courses.
Explanation:
If x is the number of courses in which Miranda register, the total cost for her tuition will be:
45 + 450x
Because there is a fixed cost of $45 and a cost per course of $450.
Then, this cost should be less than or equal to $1500, so we can write the following inequality:
45 + 450x ≤ 1500
Now, we can solve the inequality for x. Subtract 45 from both sides:
45 + 450x - 45 ≤ 1500 - 45
450x ≤ 1455
Divide both sides by 450:
450x/450 ≤ 1455/450
x ≤ 3.23
Therefore, Miranda can register for at most 3 courses.
Answer:
A, D, E
Step-by-step explanation:
The perimeter is all of the sides added together
So, since a rectangle has 2 pairs of parallel congruent sides, or 2l and 2w, anything that would result in 2l+2w would be correct.
A, l+w+l+w=2l+2w
B, l*w cant be simplified more
C, 2*l*w would end up with 2l*w due to pemdas
D, 2(l+w)=2l+2w by distribution
E, (2*l)+(2*w)=2l+2w
