Answer:

A. 1/4

Step-by-step explanation:

3/4, 1/2

"Used"

How much does Mariah have left?

___________________________

We know that originally, Mariah had 3/4 of a cup of flour, in which she then used 1/2 of that cup in a recipe. There is a dilemma here, the denominators aren't the same and we can't subtract without the same denominator. To solve, we need to get them both to the same denominator, so find what times 2 equals 4. Then multiply that same number by the numerator.

\frac{1}{2} * \frac{?}{?} = \frac{?}{4}

\frac{1}{2} * \frac{2}{2} = \frac{2}{4}

Now that 1/2 has been changed to 2/4, we can subtract.

So she has 3/4, and uses 2/4

\frac{3}{4} - \frac{2}{4} = \frac{1}{4}

Therefore, the answer is A.

Find the inverse function of f(x)=4x-8
kipiarov [429]

Answer:

f^-1(x)=1/4x+2

Step-by-step explanation:

y=4x-8

change x and y

x=4y=8

switch sides

4y-8=x

add 8

4y=x+8

divide both sides by 4

y=1/4x+2

substitute f^-1(x) for y

f^-1(x)=1/4x+2

Answer:

  2 1/4 days

Step-by-step explanation:

You could extend your table a bit to help answer this.

  (days, hours)

  (1, 24)

  (1/2, 12)

  (1/4, 6)

  (2, 48)

Now, we observe that 54 hours is 6 more hours than 48 hours, so will be 1/4 day more than 2 days.

54 hours is 2 1/4 days

Please help it’s very urgent and I need the right answer
8090 [49]

Answer:

3x + 15 = 3*10 + 15 = 30 + 15 = 45

<u>3x + 15 = 45</u>

Now,

2x + 25 = 2*10 + 25 = 20 + 25 = 45

<u>2x + 25 = 45</u>

Step-by-step explanation:

3x + 15 + 2x + 25 = 90

or, 5x + 40 = 90

or, 5x = 90 - 40

so, 5x = 50

so, x = 50/5 = 10
