3 / 1½ = 2 cups of flour per teaspoon

2x = 5
divide both sides by 2 to isolate x

x = 2.5

You need 2.5 teaspoons of vanilla for 5 cups of flour.

Answer:

Width is 24, length is 40

Step-by-step explanation:

64 can be split into 8 groups of 8, and the 8 groups can be split into 3 and 5. Then, take 3 x 8 for the width and 5 x 8 for the length, and you have the answer! I wish to you best of luck!

6/x = x-1<br> that 6overx = x-1

Juliette [100K]

6/x = x-1

Multiply x by both sides

6= x(x-1)

Set x and x-1 equal to 6

x = 6, x = 1+6 = 7

What’s the inverse of the function F(x)=2x+1

antoniya [11.8K]

Answer:

Step-by-step explanation:

1. Replace F(x) with y.

2. Interchange x and y in y = 2x + 1: x = 2y + 1

3. Solve this result for y: 2y = x - 1, or y = (x - 1)/2

4. Replace y with:

-1

F (x):

-1 x - 1

F (x) = -----------

41 guests / 8 plates = 5.125 packs

Since you cant buy .125 of a pack, Mary jane has to purchase 6 packs.

Solve the system of equations:<br><br> -5x+y-4z=60<br> 2x+4y+3z=-12<br> 6x-3y-2x=-52

Bogdan [553]

Answer:

The answer to your question is:

x = -8; y = 1 ; z = -4

Step-by-step explanation:

Δ = $\left[\begin{array}{ccc}-5&1&-4\\2&4&3\\6&-3&-2\end{array}\right]$

= 40 + 24 + 18 - (-4 + 45 - 96)

= 82 + 55

= 137

Δx = $\left[\begin{array}{ccc}60&1&-4\\-12&4&3\\-52&-3&-2\end{array}\right]$

= - 480 - 144 - 156 - ( 24 - 540 + 832)

= -780 -316

= - 1096

Δy = $\left[\begin{array}{ccc}-5&1&-4\\2&4&3\\6&-3&-2\end{array}\right]$

= 40 + 24 + 18 - ( - 4 + 45 - 96)

= 82 + 55

= 137

Δz = $\left[\begin{array}{ccc}-5&1&60\\2&4&-12\\6&-3&-52\end{array}\right]$

= 1040 - 360 - 72 - ( - 104 - 180 + 1440)

= 608 - 1156

= -548

x = -1096/ 137 = -8

y = 137 / 137 = 1

z = -548 / 137 = -4
