Answer:
x = -2, y = 2
Step-by-step explanation:
-7x + 7y = 28
7y = 28 + 7x
y = 4 + x ----(1)
-8x+4y=24 -----(2)
sub (1) into (2)
-8x+4(4+x)=24
-8x+16+4x = 24
-8x+4x = 24-16
-4x = 8
x = -2
sub x = -2 into (1)
y=4+(-2) = 2
The quotient may be greater than or less than the dividend or divisor.
When the dividend is less than the divisor, the quotient will be less than one.
When the dividend is greater than the divisor, the quotient will be greater than one.
Answer: The decimal is 0.583
Step-by-step explanation:
We have
AP = 34,36,38......,234
a, (first term) = 34
n ( total terms ) =?
d ( common difference ) = 2
so, a +(n-1)d =an
34+(n-1)*2 = 234
(n-1)2 = 234-34
n-1 = 200/2
n = 100+1
n =101
Now sum of the even no.
Sn = n/2( 2a+9n-1)d)
= 101/2 (2*34 +100*2)
= 101/2 * 268
=101 *134
= 13534
