Answer:

C. X = 1/2

Step-by-step explanation:

4x - 3 + 5 = 2x + 7 - 8x

Solve for x. log x + log 3 = log 18 Enter your answer in the box.

Makovka662 [10]

log(x) + log(3) = log(18)

log(x) + 0.477121 = 1.255273

Add -0.477121 to both sides.

log(x) + 0.477121 + −0.477121 = 1.255273 + −0.477121

log(x)+0 = 0.778152

Divide both sides by 1.

log(x)+0/1 = 0.778152/1

log(x)=0.778152

Solve Logarithm

log(x) = 0.778152

10log(x) = 100.778152

x = 100.778152

x = 6.00001

What is -4/8 reduced

kumpel [21]

If you mean simplifying -4/8 simplified is -2/4 or -1/2 which in decimal form is -0.5 so it is technically a negative half.

What is the answer to this?

katrin [286]

Answer:

$\huge\boxed{-28}$

Step-by-step explanation:

We can substitute the given values of $a$ , $b$ , and $c$ to find the value of this expression.

$-4 | a + b - c|$

$-4 | 3 + (-2) - (-6)|$

We know that two negatives make a positive. This means that $-2 - (-6)$ will be the same this as $-2+6$

$-4 | 3 + -2 + 6|$

Adding a negative is the same as subtracting a positive.

$\4 | 3-2+6|\\\\3-2+6 = 7$

$-4 \cdot 7 = -28$

Hope this helped!
