Answer:

None of the answer options are correct

Step-by-step explanation:

cs + rh = w

cs = w - rh

s = (w - rh)/c

The second one could be corrected by exchanging c with 1/c

The last one would be correct with judiciously applied parentheses.

The first and third have too many errors to even bother trying to correct.

answer could also be written

s = w/c - rh/c

but it is not considered reduced form.

Answer:

(d) s = (w − rh)/c

Step-by-step explanation:

Undo what is done to the variable. It is multiplied by c and rh is added to that product.

cs +rh = w . . . . . given

cs = w -rh . . . . . undo the addition of rh: add -rh to both sides

s = (w -rh)/c . . . . undo the multiplication by c: divide both sides by c

_____

<em>Additional comment</em>

Each entire side of the equation is divided by c. That means the entire expression (w-rh) is divided by c. It is incorrect to write that division as w-rh/c. The division bar (/) in plain text only refers to the immediately preceding and the immediately following tokens as its operands. When the expression is typeset, the division bar serves as a grouping symbol, showing you the entire numerator.

$s=\dfrac{w-rh}{c}$

The table of ordered pairs (x,y) gives an exponential function.

The equation for the exponential function containing the points (0, 8) and (1, 32) is y = 8(4)ˣ

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the multiplication factor.

At point (0, 8):

8 = ab⁰

a = 8

At point (1, 32):

32 = 8b

b = 4

The equation for the exponential function containing the points (0, 8) and (1, 32) is y = 8(4)ˣ

How many 3/4s are in 3 2/4

MArishka [77]

Answer:

the answer is 3

Step-by-step explanation:

First change the whole number (3) to quaters or fraction

3x $\frac{4}{4}$ = $\frac{12}{4}$

Now, add

$\frac{2}{4}$ + $\frac{12}{4}$ = $\frac{14}{4}$ Since, we have the same common denominator

now divide

14÷4 =3.5 = 3 $\frac{2}{4}$

Therefore, there are 3 of 3/4 with a remainder of $\frac{2}{4}$ in 3 $\frac{2}{4}$ .
