-3(x-4) + 7 = 4x - 9
Help me please!!

Answers

Answer 1

Answer:x=4

Step-by-step explanation:

Do your distribution rules to get -3x+12+7=4x-9. Then combine like variables to get -3x+19=4x-9. Add the 9 to 19 and get 28 then add the 3 to 4 to get 7. Should look like 28=7x. Divide the 7 to 28 and get the answer of 4

Answer 2

Answer:

X=4

Step-by-step explanation:

-3(x-4)+7=4x-9

-3x(12)+7=4x-9

+3x         +3x

      12+7=7x-9

         +9   +9

      12+16=7x

          28=7x

          28/7

Answers

Answer:

60%

Step-by-step explanation:

I'm not sure about the grid (as you didn't attach any images), but I can help with the percentage part. To convert a fraction into a percentage, all you have to do is multiply the fraction by 100. When we do this, we get 3/5*100 = 60%.

Another way to think about it is to rewrite 3/5 so that it's denominaor is 100. We can mutiply the fraction by 20/20 which gives us 60/100. Note that this doesn't change the original fraction because 20/20 is equal to 1. Then, you simply take the numerator as the percentage. In this case, the numerator is 60, so the percentage will be 60%.

m<1 + m<2 = 180°

m<3 + m<4 = 180°

Because they are both equal to 180°, you can set them equal to each other.

m<1 + m<2 = m<3 + m<4

Angles 1 and 4 are congruent (equal), so we can subtract them from each side to get:

Answers

Answer: There are 22.2 pounds of water in the bag.

Step-by-step explanation:

Hi, to answer this question we simply have to multiply the total weight of the bag by the water percentage in decimal form (divided by 100).

Mathematically speaking:

30 x (74/100) = 30 x 0.74 =22.2 pounds

What is the value of y?

A. 630
B. 126°
C. 73°
D. 54°

Answers

Answer:

y = 63

Step-by-step explanation:

The sum of the angles of a triangle is 180

54+y+y = 180

Combine like terms

2y+54 = 180

Subtract 54 from each side

2y+54-54= 180-54

2y =126

Divide each side by 2

2y/2 = 126/2

y =63

Answer:

A. 63 degrees

Step-by-step explanation:

All angles added together would equal 180. We have two angles that equal y and a third that has 54. Our first step:

180-54=126

Both of the y angles equal 126. We want a separate value though, so we divide this by two.

126/2=63

Thus, A is our answer

How To Find The nth Term Of A Geometric Sequence

Written by Hazmo  in Geometric Sequence

The nth term is one of the most important element of geometric sequence.

It’s usually used to find out specific values within the geometric sequences.

We calculate the nth term by first finding the common ratio ‘r’ by dividing any two consecutive terms of the sequence.

And then we substitute ‘a‘ with the first term of the sequence and ‘n’ with the term number to get the final answer of the nth term.

The general formula to find the nth term is:

an=a1r(n–1)

Understanding the nth term of a geometric sequence gets easier if we know the meaning of this term and variables used.

Therefore, let’s first find what the nth term is and then move on to the details of it’s evaluation with different examples.

The rule that is generated is 3, 9, 27, ........  an.

What is geometric progression ?

"Geometric Progression (GP) is a type of sequence where each succeeding term is produced by multiplying each preceding term by a fixed number, which is called a common ratio. This progression is also known as a geometric sequence of numbers that follow a pattern."

Given,

a3 = 27

and r = 3

Formula for nth term is given by

[tex]a_{n} = a_{1}r^{n-1}[/tex]

so, we have

[tex]27 = a1.3^2[/tex]

so a1 = 3

Hence, the series becomes 3, 9, 27, ........an

A particular type of cell increases by 75% in number every hour. Find the number of cells present at the end of 12 hours if there are initially 4 of these cells?

Answers

We have been given that a particular type of cell increases by 75% in number every hour. We are asked to find the number of cells present at the end of 12 hours if there are initially 4 of these cells.

We will use exponential growth formula to solve our given problem.

[tex]y=a\cdot (1+r)^x[/tex], where,

y = Final amount,

a = Initial amount,

r = Growth rate in decimal form,

x = Time.

[tex]75\%=\frac{75}{100}=0.75[/tex]

Upon substituting initial value [tex]a=4[/tex] and [tex]x=12[/tex] in above formula, we will get:

[tex]y=4\cdot (1+0.75)^{12}[/tex]

[tex]y=4\cdot (1.75)^{12}[/tex]

[tex]y=4\cdot 825.0050068497657776[/tex]

[tex]y=3300.020027[/tex]

[tex]y\approx 3300[/tex]

Therefore, there will be approximately 3300 cells at the end of 12 hours.
