Answer:
A 61377
B 87405
Step-by-step explanation:
If sum of the digits of a number is divisible by 3, then that number is also divisible by 3.
Option A:
Given number is: 61377
Sum of the digits = 6+1+3+7+7 = 24
24 is divisible by 3, hence 61377 is also divisible by 3.
Option B:
Given number is: 87405
Sum of the digits = 8+7+4+0+5 = 24
24 is divisible by 3, hence 87405 is also divisible by 3.
Option C:
Given number is: 30898
Sum of the digits = 3+0+8+9+8 = 28
28 is not divisible by 3, hence 30898 is also not divisible by 3.
Similarly, sum of the digits of the numbers in options D, E and F are 8, 22 and 26 respectively, which are not divisible by 3, hence the numbers 6020, 29830 and 75932 are also not divisible by 3.
Answer:
x=−3 and y=4
Step-by-step explanation:
Multiply the first equation by -2,and multiply the second equation by 1.
−2(2x+5y=14)
1(4x+2y=−4)
Becomes:
−4x−10y=−28
4x+2y=−4
Add these equations to eliminate x:
−8y=−32
Then solve−8y=−32for y:
−8y=−32
−8y
−8
=
−32
−8
(Divide both sides by -8)
y=4
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
2x+5y=14
Substitute4foryin2x+5y=14:
2x+(5)(4)=14
2x+20=14(Simplify both sides of the equation)
2x+20+−20=14+−20(Add -20 to both sides)
2x=−6
2x
2
=
−6
2
(Divide both sides by 2)
x=−3
