Grandma baked 1.5 times as many pancakes as waffles. After she baked 45 more waffles, and her grandchildren ate 12 pancakes, the

Komok [63]

Step-by-step explanation:

let x represent the no of pancakes,

she baked 1.5 times pancakes more than waffles,

so from this, no of pancakes = 1.5x,

then she baked more 45 waffles,

no of waffles = (x +45)

so you had 1.5x pancakes and the children ate 12 out of them. the no of pancakes has then been reduced by 12.

thus, no of pancakes = ( 1.5x -12 )

now they see that they have 17 more waffles that pancakes left. this means that :

no of waffles - no of pancakes = 17

(x+45) - (1.5x - 12) = 17

x - 1.5x + 45 + 12 = 17

x = -50 / -0.5

x = 100

hence, there were 100 waffles initially.

hope you understand this,

If F(x) = log 4 3x, find F -1(x). A.4^y=3x B.4^x=3y C.4^3y=x

lara31 [8.8K]

Answer:

${f}^{ - 1} (x) = \frac{{4}^{x} }{3}$

Step-by-step explanation:

The given logarithmic function is

$f(x) = log_{4}(3x)$

Let y=f(x)

This gives us:

$y = log_{4}(3x)$

We interchange x and y to get:

$x = log_{4}(3y)$

${4}^{x} = 3y$

$y = \frac{{4}^{x} }{3}$

Therefore the inverse is

${f}^{ - 1} (x) = \frac{{4}^{x} }{3}$

Based on the possible answers, B is most closed to the inverse.

The correct answer is B

iragen [17]

Answer
456.50=159 + 3.5x
OR
3.5x=456.50-159

Reason
456.50 is the total
159 is for the parts
3.5 is the number of hours

So to find the cost you have to find out how much it cost for the labor by subtracting the total cost from the cost of the parts. To find the cost of labor for each hour you have to divide the total cost of labor by the number of hours used to work on the computer
