5 would be the dependent variable because the number 5 depends on how many greeting cards are bought.
since its an isoscelies trangle, they probably wanted you to do base times height
make a 71-91/2-x x triangle
where x is the height of the triangle to the base 91 and 71 is the hypothenuse
and then do bh/2
or
use heron's formula
s= 71+91/2
area= 
have fun solving that
Answer:
Jamal received 2,880 votes
Step-by-step explanation:
In the election,
Jamal received 40% of all votes
Tran received 100% - 40% = 60% that is 4,320 votes
Let x be the number of votes Jamal received. Then
x - 40%
4,320 - 60%

Answer:
Enlargement
Step-by-step explanation
It is enlargement, because it went up by three. Instead of reducing.
Start with how much profit they are making off each race entry. People pay $55 to race, but $15 of that is expenses so they are only profiting $40 for each entry. Now write one side of the equality. They start with $10,000 in donations, and then have a $40 profit for each race entry. So 10,000+40x. X will represent the unknown number of race entries. What do we want that expression to be equal to? We want 10000+40x>55000. It can also be greater than or equal to, not just greater than.
Solve for x. Subtract 10000 from each side resulting in 40x>45000. Divide each side by 40 to solve for x. X>1125. X needs to bbe greater than or equal to 1125. If there are 1125 race entries, the charity will profit exactly $55000, so the lowest number of race entries is 1125
