Make b the subject of the formula: S=ab-bc

Here, you just want to solve for b. because the right side of the equation doesn't have any like terms, you have to factor that b out:

s = ab - bc
s = b(a - c)

divide both sides by (a - c)

s/(a - c) = b is your answer. it's "s" over "a - c" if the formatting is difficult to read

S=ab-bc
factorise it:
s=b(a-c)
divide by (a-c) to isolate 'b':
2/(a-c)=b

Hope this helps :)

What values of b satisfy 3(2b + 3)2 = 36?

meriva

What values of b satisfy 3(2b+3)^2 = 36

we have
3(2b+3)^2 = 36
Divide both sides by 3
(2b+3)^2 = 12
take the square root of both sides
( 2b+3)} =(+ /-) \sqrt{12} \\ 2b=(+ /-) \sqrt{12}-3

b1=\frac{\sqrt{12}}{2} -\frac{3}{2}
b1=\sqrt{3} -\frac{3}{2}

b2=\frac{-\sqrt{12}}{2} -\frac{3}{2}
b2=-\sqrt{3} -\frac{3}{2}
therefore

the answer is
the values of b are
b1=\sqrt{3} -\frac{3}{2}
b2=-\sqrt{3} -\frac{3}{2}

Use exponential form to evaluate log8(2)

maks197457 [2]

<span>Logarithm form is another way to express a number in exponential (exp.) form. log 8 (2) is the same as 8 (x) = 2 or in words, eight with exp. x equals two. If we take that equation and cube both sides, or raise each side to the power of 3, [8 (x)] with exp. 3 = 2 with exp. 3. This simplifies to 8 (3x) = 8. By definition, 8 is the same as 8 with exp. 1. So the equation is now 8 (3x) = 8 (1). This means 3x = 1. We can simplify to x = 1/3.</span>

112.5 miles because 4x25=100 and half of 25 is 12.5 so 100+12.5= 112.5
technically 4.5x25=112.5

Suppose you roll a pair of honest dice. If you roll a total of 7 you win $22, if you roll a total of 11 you win $66, if you roll

JulijaS [17]

Answer:

The expected payoff for this game is -$1.22.

Step-by-step explanation:

It is given that a pair of honest dice is rolled.

Possible outcomes for a dice = 1,2,3,4,5,6

Two dices are rolled then the total number of outcomes = 6 × 6 = 36.
