just eyeballing it I know that 4 + 9 = 13 so lets assume x = y = 2. Now to solve the second equation to see if my hunch is right
2^(2+2) + 3^(2+1) = 43
2^4 + 3^3 = 43
16 + 27 = 43
43 = 43
turns out was right lol so 2^x = 2^2 = 4
Answer: 4
this problem looks confusing...
simplified: 2 - 6x - 8x^2 = -8x^2 -6x + 2
A = -8
B = -6
C = 2
A + B + C = -12
f = number of stamps Fann has
a = number of stamps Alex has
f = 2 3/5 * a
f:a = 2 3/5 : 1
ratio is 1: 2 3/5 or 1: 13/5
Natalie took 1/4 of a day so 24*1/4 = 6 hours
Kevin took 2/3 the time Natalie took so 6*2/3 = 4 hours
6 - 4 = 2
Kevin did his homework 2 hours faster than Natalie
don't rly wanna explain why im doing what im doing cus the diagram I made to solve this is kinda weird
20^2 * pi = 400pi
3/4 (400pi) = 300pi
10^2 * pi = 100pi
100pi/2 = 50pi
300pi + 50pi = 350pi
answer is 350pi
d = common difference
x+3+d = 3x-10
d = 2x-13
3x-10+d = 2x+12
d = -x + 22
2x-13 = -x+22
3x = 35
x = 35/3
Checking answer:
35/3 + 9/3 = 44/3
35-10 = 25 = 75/3
70/3 + 12 = 70/3 + 36/3 = 106/3
106/3 - 75/3 = 31/3
75/3 - 44/3 = 31/3
M = Mother's age 8 years ago
B = brother's age 8 years ago
M = 4B + 4
M+8 = 3(B+8) - 5 -> M+8 = 3B+24-5 -> M = 3B + 11
4B + 4 = 3B + 11
B = 7
B+8 = 15
Answer: 18
pretty sure thats the answer lol if not then I messed up somewhere
1/3 - 1/4 = 1/12 so 1/12 of Lemmie's toys is 18, so to get half of Lemmie's toys we need to find how much 6/12 of Lemmie's toys is so 18*6 = 108
