Answer:
x = 10 and BD = 74
Step-by-step explanation:
AE and CE are equal, so we can set those 2 values equal to each other to find x.
3x + 7 = 37
3x = 30
x = 10
BD will be equal to AE + CE because that is a property of the rectangle.
So AE + CE = 37 + 37 = 74.
BD = 74
Answer:
2
Step-by-step explanation:
So each team must have have the same number of boys as girls
the way to get the most teams is to have the least people on them
the min per team is 1 boy and 1 girl
25 is less than 28 so the limit is 25
there are only25 boys so the max number is 25 teams
Answer:
n+30/5
Step-by-step explanation:
Simplify n/5
n/5+6
Rewrite the whole as an equivalent fraction
2.1 Add an integer to a fraction
Rewrite the whole as a fraction using 5 as the denominator: 6= 6/1=6×5/5
Equivalent fraction: the fraction thus generated looks different but has the same value as everything.
2.2 sum of the two equivalent fractions add two equivalent fractions that now have a common denominator
Combine the numerators, place the sum or difference over the common denominator, and then reduce to the lowest terms of possible:
n+6×5/5=n+30/5
Answer:
4
Step-by-step explanation:
Since the base is the same, 3, you can just get rid of it using the principles of log. What you're left with is:
2x + 1 = x + 5
Now just solve for x:
2x - x = 5 - 1
x = 4
