Answer:

Step-by-step explanation:

$10+6(-9-4x)=10(x-12)+8$

$10-54-24x=10x-120+8$

$-44-24x=10x-112$

$-44=34x-122$

$78=34x$

What’s the Answer to this I got 24 somehow

Bess [88]

Answer:

Step-by-step explanation:

So we have the expression:

$\frac{2x+y}{xy-2x}$

And we want to evaluate it for x=-4 and y=8.

So, substitute:

$\frac{2(-4)+(8)}{(-4)(8)-2(-4)}$

Multiply:

$=\frac{-8+8}{-32+8}$

Add:

$=\frac{0}{-24}$

Evaluate:

$=0$

So, our answer is 0.

And we're done!

Determine the sum of the arithmetic series: 5+18 +31 +44 + ... 161.

Finger [1]

Answer:

1079

Step-by-step explanation:

Hello,

18-5 = 13

31-18=13

44-31=13

161=5+13*12

So we need to compute

$\displaystyle \sum_{k=0}^{k=12} \ {(5+13k)}\\\\=\sum_{k=0}^{k=12} \ {(5)} + 13\sum_{k=1}^{k=12} \ {(k)}\\\\=13*5+13*\dfrac{12*13}{2}\\\\=65+13*13*6\\\\=65+1014\\\\=1079$

Thanks
