Answer:

X=10

Step-by-step explanation:

2(4x+9)=98

There is a very simple way to solve this

Whatever you get in the parentheses will be multiplied by 2

so 98/2 is 49

you subtract 9 from 49 because you will add 9 to X

so 49-9=40

Now all you have to do is times x by 4 to get 40

Divide the 40 by 4 and you get 10

So X=10

(Remember in these problems to do them thhis way normally if it says to multiply you divide. Do the opposite)

Find the numerical value of the log expression. \log a=7\hspace{15px} \log b=10\hspace{15px} \log c=3 loga=7logb=10logc=3 \log \

bija089 [108]

Answer:

Step-by-step explanation:

$\log a=7\hspace{15px} \log b=10\hspace{15px} \log c=3\\\\ \log \dfrac{a^8c^2}{b^3}=8\log{a}+2\log{c}-3\log{b}=(8)(7)+(2)(3)-(3)(10)\\\\=56+6-30=\boxed{32}$

The applicable rules of logarithms are ...

log(ab/c) = log(a) +log(b) -log(c)

log(a^b) = b·log(a)

Solve c: P = a+b+c+d / 4

m_a_m_a [10]

Answer:

as written: c = P - a - b - d/4
with parentheses: c = 4P - a - b - d

Step-by-step explanation:

The meaning of the given expression is ...

P = a + b + c + (d/4)

To solve for c, subtract all the terms on the right side not containing c.

P -(a + b + (d/4)) = c

c = P - a - b - (d/4)

_____

In such equations, parentheses are commonly missing. If that is the case here, then first we undo the division by 4, then we subtract the "not c" terms.

P = (a + b + c + d)/4 . . . . maybe what you meant

4P = a + b + c + d . . . . . . multiply by 4

4P - (a +b +d) = c

c = 4P -a -b -d
