Answer:
28
Step-by-step explanation:
65% of x = 52
x= 52*100/65 = 80
now
35% of 80 = 35/100 * 80 = 28
If you want to form a square of 7500 soldiers, the side of the square must be 
soliders.
But since you cannot have 0.6 solider, the general needs to find the closest perfect square to the number 7500 which is less than 7500.
That number is 7396 which when square rooted gives 86 soliders on the side.
Subtract 7396 from 7500 and get how many soliders were left out,
Hope this helps :)
Answer:
0
Step-by-step explanation:
10 to the power of 0, is equivalent to 0. Since their is no given value, it is saying "226÷0" which equals 0.
Ok here it is:
4x-5y=40
2x+10y=20
I used the second equation and decided to get x
2x+10y=20
Subtract 10y from both sides.
2x=-10y+20
Divide both sides by 2
x=-5y+10
Put that in for x for first equation
4(-5y+10)-5y=40
Distribute the 4
-20y+40 -5y =40
Combine like terms
-25y+40=40
Subtract 40 from both sides
-25y=0
Divide by -25 on both sides
y=0
Substitute the y in for the 2nd equation
2x+10(0)=20
2x=20
Divide both sides by 2
x=10
So x=10 and y=0
Answer:
3x+19
Step-by-step explanation:
2x are like terms and 4 and 15 are like terms so you add them together
