Answer:

The missing number would be 22.

Step-by-step explanation:

The missing number would be, lets say <em>x</em>.

(<em>x</em> - 8) / 7 = 2

First, lets multiply 2 by 7.

2 * 7 = 14

Next, lets add 8 to 14.

8 + 14 = 22

The missing number would be 22.

To check this answer, subtract 8 from 22 which would be 14.

Then divide by 7 which would be 2. This answer is correct.

Therefor, the missing number, or x, would be 22.

Hope this helps!

Answer:

5y-35

Step-by-step explanation:

since we don't know what y is you have to multiply y and 7 by 5 and you'd get 5y and 35 and then just add the subtraction and bam there's your answer

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 18 N acts on

inysia [295]

Answer: $F=15N$

Step-by-step explanation:

1. You know that the force acting on the object varies directly with the object's acceleration. Then, by definition, you have:

$F=ka$

Where $F$ is the force acting on the object, $a$ is the object's acceleration and $k$ is the constant of proportionality.

2. Keeping this on mind, you can calculate the constant of proportionality by substituting $F=18$ and $a=6$ into the equation and solving for $k$ :

$18=k6\\k=\frac{18}{6}\\k=3$

3. Now, you can calculate the force when the acceleration of the object becomes 5 m/s², as following:

$F=3(5)\\F=15$

3. The result is:

$F=15N$

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, the

san4es73 [151]

Answer:

We get value of the value of b = 5

Step-by-step explanation:

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, then m=m equals negative StartFraction 1 Over 6 EndFraction.. What is the value of b?

We have slope m: $m=-\frac{1}{6}$

We need to find value of b (y-intercept)

Using the point A(-6,6) and slope $m=-\frac{1}{6}$ we can find b.

Using slope-intercept form, putting values of m and x and y we get the value of b:

$y=mx+b\\6=-\frac{1}{6}(-6)+b\\6=1+b\\b=6-1\\b=5$

So, we get value of the value of b = 5
