Let the cosecutive numbers be like this :
2n + 1 , 2n + 2 , 2n + 3 , 2n + 4 , 2n + 5
Odd , Even , Odd , Even , Odd
______________________________
So we have :
(2n+1)+(2n+3)+(2n+5)=(2n+2)+(2n+4) + 39
6n + 9 = 4n + 6 + 39
6n + 9 = 4n + 45
Subtract both sides 9
6n + 9 - 9 = 4n + 45 - 9
6n + 0 = 4n + 36
6n = 4n + 36
Subtract both sides 4n
6n - 4n = 4n - 4n + 36
2n = 0 + 36
2n = 36
Divide both sides by 2
2n ÷ 2 = 36 ÷ 2
<em>n</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em> </em>
______________________________
So the numbers are :
2(18)+1 , 2(18)+2 , 2(18)+3 , 2(18)+4 , 2(18)+5
36 + 1 , 36 + 2 , 36 + 3 , 36 + 4 , 36 + 5
37 , 38 , 39 , 40 , 41
As u can see the Odd numbers are :
37 , 39 , 41
And we're done ...
Answer:
shirt= $8
cap=$3
Step-by-step explanation:
rearrange one of the equations
y=11-x
then plug into the other equation
2x+3(11-x)=25
solve
2x+33-3x=25
-x+33=25
subtract 33 from both sides
-x=-8
divide by -1
x=8
the put that answer into original equation
8+y=11
subtract 8 from both sides
y=3
Answer:
80/3 or 26 2/3
Step-by-step explanation:
-2 + y = 9 (subtract y from both sides)
-2 = 9 - y (subtract 9 from both sides)
-2 - 9 = y (multiply both sides by -1)
2 + 9 = y (simplify)
11 = y (substitute)
3x - 7 (11) = 3 (multiply)
3x - 77 = 3 (subtract 3 from both sides)
3x - 80 = 0 (subtract 3x from both sides)
-80 = -3x (multiply both sides by -1)
80 = 3x (divide both sides by 3)
80/3 = x (simplify if needed)
26 2/3 = x
D)2401
7^4=7^2×7^2=49×49=2401
Answer:
i think its D
Step-by-step explanation:
The amount she wants to donate is 593, and she has 418 already so subtract that from 593 to get 175, and divide that 175 by 12.50 to get 14 days, and the solid circle means greater than or equal to 14, so it should be D.
