3 subtracted by 7 times a number

Answer:

16.16.16

Step-by-step explanation:

please let me know if I'm wrong

but I learned that you don't do 4×2 you have to multiply 4 twice by itself so it would be 16 because 4×4=16

Answer:

Step-by-step explanation:

The slope is the change of y over the change of x.

the change of y:77-22=55

the change of x:49-14=35

55/35 simplified is 11/7

Step-by-step explanation:

From the question, to make the punch recipe, the following are needed:

Ginger Ale - 40%

Orange Juice - 25%

Pineapple juice - 20%

Sorbet - 15%

Since we are told that Elise doesn't like sorbit, so she omits that ingredient and adds 5 percent to each of the other ingredients. The the new percent will be:

Ginger Ale - 40% + 5% = 45%

Orange Juice - 25% + 5% = 30%

Pineapple juice - 20% + 5% = 25%

Sorbet - 15% - 15% = 0

To get the total cups of punch that'll be used, let it be represented by y. Therefore,

30% of y = 6

30/100 × y = 6

0.3 × y = 6

0.3y = 6

y = 6/0.3

y = 20

Therefore, she'll have 20 cups of punch.

Answer:

The reason why it helps to have a plan of proof before writing the proof is that the proof plan is the collection of recollected knowledge about the question that will ensure that the required proof is achieved

The proof plan is equivalent to a  virtual construction, consisting of the required parts and how the parts fit together, that obeys or satisfies the actual conditions when the written, step by step on paper

Without a proof plan, the required parts of the proof and therefore how the parts will fit to provide the proof will be absent as well as the non required parts written down to provide a proof without a plan can be confounding

Answer:

The answer is letter D.

If we solve the given function when the functions are f(x)=[tex]\sqrt{6x}[/tex] and g(x)=[tex]\sqrt{24x}[/tex] then we will be able to find it equal to 12x.

A function is a relation in which each element of x is having a value in the y element. It is written in the form of f(x).

f(x)=[tex]\sqrt{6x}[/tex] and g(x)=[tex]\sqrt{24x}[/tex]

(f.g)x=f(x)*g(x)

=[tex]\sqrt{6x} *\sqrt{24x}[/tex]

=[tex]\sqrt{6x}*2\sqrt{6x}[/tex]

=2*6x

=12x

Hence the value of (f.g)x is 12x.

Given:

Initial speed of typing = 35 words per minute

At the end of the course her typing speed = 77 words per minute

To find:

The percent of increase in her typing rate.

Solution:

We know that,

[tex]\text{Percent of increase in her typing rate}=\dfrac{\text{New speed - initial speed}}{\text{Initial speed}}\times 100[/tex]

[tex]\text{Percent of increase in her typing rate}=\dfrac{77-35}{35}\times 100[/tex]

[tex]\text{Percent of increase in her typing rate}=\dfrac{42}{35}\times 100[/tex]

[tex]\text{Percent of increase in her typing rate}=120\%[/tex]

Therefore, her typing rate is increased by 120%.

Answer:

D

Step-by-step explanation:

The answers would be z + w = -2 + 3i, z - w = 4 - 7i, and w - z = 4 + 7i after adding and subtracting two complex numbers.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

It is given that:

The complex numbers are:

z = 1 - 2i and w = -3 + 5i

z + w = 1 - 2i - 3 + 5i

z + w = -2 + 3i

z - w = 1 - 2i + 3 - 5i

z - w = 4 - 7i

w - z = 4 + 7i

Thus, the answers would be z + w = -2 + 3i, z - w = 4 - 7i, and w - z = 4 + 7i after adding and subtracting two complex numbers.
