Solve for x: one over eight (8x + 15) = 24
Vsevolod [243]
The answer is 177/8 or one hundred seventy seven over eigth.

1/8(8x + 15) = 24

Multiply both sides by 8:
8* 1/8(8x + 15) = 8 * 24
8x + 15 = 192


Subtract 15 from both sides:
8x +15 - 15 = 192 - 15
8x = 177

Divide both sides by 8:
8x/8 = 177/8
x = 177/8

Evaluate (98 x 102) by using suitable identities.
GREYUIT [131]

Answer:

The answer is 9996

Step-by-step explanation:

Using the identity (x+a)(x+b) = x  ^2  +(a+b)x+ab

Writing 102 as 100+2 and 98 as 100−2

Hence (100+2)(100−2) = 100  ^2  +[2+(−2)]100+(2)(−2)

= 10000+(0)100−4

= 9996

The answer is 9996
