Amount of salt that would be used = 1 $\frac{3}{4}$ x $\frac{1}{3}$

Convert $1\frac{3}{4}$ to an improper fraction

to convert to improper fraction, take the following steps :

1. Multiply the whole number by the denominator

2. Add the numerator to the answer gotten in the previous step

3. divide the number gotten in the previous step by the denominator

(1 x 4) + 3 = $\frac{7}{4}$

Answer:

ln(2) + 3ln(a) - 4ln (b)

Step-by-step explanation:

ln(2a^3 /b^4)

We know that ln(x/y) = ln (x) - ln y

ln(2a^3 ) - ln (b^4)

We know that ln (xy) = ln x + ln y

ln(2) + ln(a^3 ) - ln (b^4)

We know that ln(x^y) = y ln (x)

ln(2) + 3ln(a) - 4ln (b)

What is (1-i)^3 Please explain how you got that

My name is Ann [436]

$\bf (1-i)^3\implies ~\hfill \begin{array}{cccccccl} 1^3&+&3(1)^2(-i)^1&+&3(1)^1(i)^2&+&(-i)^3\\\\ 1&+&(-3i)&+&(3i^2)&+&(-i^3)\\\\ 1&-&3i&+&3i^2&-&i^3 \end{array} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{let's recall that}}{i^2=-1\qquad \qquad i^3=-i} \\\\[-0.35em] ~\dotfill\\\\ 1-3i+3(-1)-(-i)\implies 1-3i-3+i\implies -2-2i$

Step-by-step explanation:

Step 1: Define

-12(x + 4) + 14x = 60

Step 2: Solve for x

Distribute -12: -12x - 48 + 14x = 60
Combine like terms: 2x - 48 = 60
Add 48 to both sides: 2x = 108
Divide 2 on both sides: x = 54

-5x+4y=3 x=2y-15 Solve for y and x

serious [3.7K]

Answer:

x=9, y=12

Step-by-step explanation:

-5x+4y=3 --------A

x=2y-15----------B

Putting the value of x from B in A

-5(2y-15) +4y=3

-10y+75+4y=3

-6y=3-72

-6y=-72

y=72/6= 12

Putting the value of y =12 in B

x= 2(12)-15

x= 24-15

x=9

13y-7y=9 Solve for y, write it as a reduced fraction.

raketka [301]

Answer:

3/2 OR 1 1/2

Step-by-step explanation:

Collect like terms, meaning combine both y's. You should have something like this afterwards.

6y = 9

Now that you have that divide the 6 on both sides so Y is by itself!

Your answer is now 3/2.
