4/1 = 12/y ​what does y= its on khan academy

subtract 5 from both sides -

5x - 7 = -10x + 8

-5 -5

-7 = -15x + 8

subtract 8 from both sides -

-7 = -15x + 8

-8 -8

-15 = -15x

now divide both sides by -15 -

-15/-15 = -15x/-15

The answer: x = 1

(x alone also equals 1)

Answer:

I don't know what i do not know

Answer:

Step-by-step explanation:

We can observe each term is twice as less than the previous term.

This is the indication the sequence is geometric and the common ratio is:

Answer:

2(x-5)+6=14 is your starting equation, and then we solve:

2(x-5)+6=14

2(x-5)/2 +6=14/2

x-5+6=7

the first step is to divide by 2, so A :)))

Answer:

The answer is 5

Step-by-step explanation:

The equation given is y=5x+3 and since the 5 is in the place of m from the general equation, 5 is the slope. Since parallel lines have the same slope, 5 is the answer. The slope is 5.

The slope is the ratio of rise to run of a line. The gradient of the line y=5x-3 is 5

The gradient of a line is also known as the slope and it is the ratio of rise to run of a line

The standard equation of a line in slope-intercept form is expressed as y = mx +b

m is the slope or gradient

Given the equation of a line y = 5x - 3

Compare

mx = 5x

m = 5

Hence the gradient of the line y=5x-3 is 5

Answer:

q = [tex]\frac{6+3p}{5}[/tex]

Step-by-step explanation:

[tex]\frac{5(q+p)}{2}[/tex] = 3 + 4p ( multiply through by 2 to clear the fraction )

5(p + q) = 6 + 8p ← distribute parenthesis on left side )

5p + 5q = 6 + 8p ( subtract 5p from both sides )

5q = 6 + 3p ( divide both sides by 5 )

q = [tex]\frac{6+3p}{5}[/tex]

The number of pages the student can read in a minute is an illustration of rates.

The time left to complete the whole book is 90 minutes

From the complete question, the student's rate is:

[tex]\mathbf{Rate = 50\ pages/hr}[/tex]

The number of pages is:

[tex]\mathbf{Total = 100\ pages}[/tex]

First, we calculate the time to read the whole book

[tex]\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}[/tex]

[tex]\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}[/tex]

[tex]\mathbf{Total\ Time = 2\ hours}[/tex]

The number of the student has read is:

[tex]\mathbf{Pages = 25}[/tex]

Next, we calculate the time spent on the 25 pages

[tex]\mathbf{Time\ Spent = \frac{Pages}{Rate}}[/tex]

[tex]\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}[/tex]

[tex]\mathbf{Time\ Spent = 0.5\ hr}[/tex]

Convert to minutes

[tex]\mathbf{Time\ Spent = 30\ minutes}[/tex]

So, the time left is:

[tex]\mathbf{Time\ Left = Total\ Time - Time\ Spent}[/tex]

This gives

[tex]\mathbf{Time\ Left = 2\ hours- 30\ minutes}[/tex]

[tex]\mathbf{Time\ Left = 1\ hour, 30\ minutes}[/tex]

Convert to minutes

[tex]\mathbf{Time\ Left = 90\ minutes}[/tex]

Hence, the time left is 90 minutes

Answer:

4284in

Step-by-step explanation:

Because 14*18*17 is 4284

Answer:

17 .........is the answer

Answer:

the missing value is 17.......

Answer:

Y / N = 3 / 2

N + Y = 4440

Since Y = 3/2 N

3/2 N + N = 4440

5/2 N = 4440

N = 8880 / 5 = 1776

Y = 1776 * 3 / 2 = 2664

1776 + 2664 = 4440

2664  / 1776 = 3 / 2

Answer:

Well 34 can be divided by anything...

Step-by-step explanation:

34/1 = 34

34/2 = 17

34/3 = 11.3333

34/4 = 8.5

34/5 = 6.8

34/6 = 5.6666
