Answer:

Step-by-step explanation:

$\frac{1}{4} / \frac{5}{6}$

To do this all we do is take the reciprocal of the second set of numbers (5/6)

So for 1/a, a would still be 4 as that does not change

However, b would now be 6 and c would now be 5.

Answer:

$\boxed {\boxed {\sf Haircut: \$47 \ and \ Color: \$ 100}}$

Step-by-step explanation:

Let's set up a system of equations. (1 equation for yesterday and 1 for today).

Let h = haircut and c= color

$2h+1c= 194$ (Yesterday: 2 haircuts and 1 color for $194).

$2h+4c= 494$ (Today: 2 haircuts and 4 colors for $494).

Notice that both equations have a 2h. If we subtract the two equations, the 2h will cancel and leave us with one variable, c.

$\ \ (2h+1c=194) \\- (2h+4c=494)$

$\ \ 1c=194 \\- (4c=494)$

$-3c= -300$

Since we are solving for c, we must isolate the variable. It is being multiplied by -3. The inverse of multiplication is division. Divide both sides by -3.

$-3c/-3=-300/-3 \\c= -300/-3 \\c=100$

Now we have to solve for h. Plug 100 in for c in the first equation.

$2h+1(100)= 194 \\2h+100=194$

100 is being added, so we must subtract 100 from both sides.

$2h+100=194-100 \\2h=94$

h is being multiplied by 2, so we divide both sides by 2.

$2h/2=94 \\h=47$

A haircut costs $47 and a color costs $100.

When x^3 + 2x^2 - 7x + a is divided by (x-2) the remainder is 4. Find the value of a. Please help

12345 [234]

Answer:

a = - 8

Step-by-step explanation:

A polynomial divided by factor (x - h) has a remainder given by f(h)

Here the divisor is (x - 2), thus f(2) gives the remainder, that is

2³ + 2(2)² - 7(2) + a = 4 ← 4 being the remainder

8 + 8 - 14 + a = 4, that is

12 + a = 4 ( subtract 12 from both sides )

a = - 8
