Answer: 320 boys
Step-by-step explanation: you would first take the total number (720) and divide it by the total number shown in the ratio (5+4=9)
720/9= 80
You would then take 80 and multiply it by 4 because that is the number representing the boys
80*4= 320
Answer:
67.5cm^2
Step-by-step explanation:
area of a triangle is 0.5xaxb
The equation
P(t) = 1405233 * (1 - 0.011)^(t)
models the population at t years after 2010. Then, when P(t) = 1,200,000, we have
1200000 = 1405233 * (0.989)^t
(0.989)^t = 1200000/1405233
t = log(1200000/1405233)/log(0.989)
t = 14.27 years
This means 14.27 years after 2010. Therefore, the answer to this question is 2024.
Answer: The third term is -14
----------------------------------------------
Explanation:
First term = A(1) = 20, which is given
Second term
A(n) = A(n-1) - 17
A(2) = A(2-1) - 17
A(2) = A(1) - 17 .... note: second term = (first term) - 17
A(2) = 20 - 17
A(2) = 3
Third term
A(n) = A(n-1) - 17
A(3) = A(3-1) - 17
A(3) = A(2) - 17 ... note: third term = (second term) - 17
A(3) = 3 - 17
A(3) = -14
Answer:
No Solution
Step-by-step explanation:
12x + 3 = 72x + 5
subtract 12x from both sides
end up with
3 = 72x - 12x + 5
subtract 12x to 72x
3 = 60x + 5
-5 from both sides
-8 = 60x
since x is a bigger number the answer would be NO SOLUTION
12x + 3 = 72x + 5
I do not understand lins logic
x + 6 = 7x + 10
subtract 6 from both sides
x = 7x + 4
move 7x to the other side
7x = 4
divide 7
x = 0.5
Also wrong because I get how lin got that answer
My way
12x + 3 = 72x + 5
-12 x from both sides
3 = 60x + 5
+5 to other side
8 = 60x
if the x was on the other side it would make sense
but it is not so the Answer is NO SOLUTION
Hope this Helped :)
