Solve for u. -24 = u ÷ 6

u = ____

Answers

Answer 1
Answer:

The value of u is -144

Solution:

Given that,

-24 = u / 6

We have to solve for "u"

From given,

-24 = u / 6

Convert the division problem into multiplication, by changing the division sign to multiplication sign. Then invert the number to right of division sign

Thus we get,

-24 = u * (1)/(6)\n\n(u)/(6) = -24

Isolate for u

u = -24 * 6\n\nOn\ multiplying\ both\ we\ get\n\nu = -144

Thus the value of u is -144

(3x-7)/(5)=t
multiply both sides by 6

PLease help and best gets brainliest.School is 2 miles from home along a straight road. The table shows your distance from home as you walk home at a constant rate.

Time(mins): 10-20-30
Distnce(mi)1.5-1-0.5

1)Is the relationship in the table
proportional?
2)Find your distance from school fro each time in the table
3)Write an equation representing the relationship between the distance from school and time walking.

Answers

Part 1) Is the relationship in the table proportional?

Let

y-------> your distance from home in miles

x-------> the time in minutes

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

A(10,1.5)\nB(20,1)

Find the slope AB

the slope is equal to

m=((y2-y1))/((x2-x1))

Substitute the values

m=((1-1.5))/((20-10))

m=((-0.5))/((10))

m=-0.05

Find the equation of the line with m and the point A

y-y1=m(x-x1)

y-1.5=-0.05*(x-10)

y=-0.05x+0.5+1.5

y=-0.05x+2

therefore

The answer part 1) is

the relationship in the table is not proportional

Part 2) Find your distance from school fro each time in the table

for

x=10\ minutes\ny=1.5\ miles\n distance\ from\ school= 2-1.5=0.5\ miles

for

x=20\ minutes\ny=1\ miles\n distance\ from\ school= 2-1=1\ miles

for

x=30\ minutes\ny=0.5\ miles\n distance\ from\ school= 2-0.5=1.5\ miles

Part 3) Write an equation representing the relationship between the distance from school and time walking

Let

y-------> your distance from school in miles

x-------> the time in minutes

A(10,0.5)\n B(20,1)

Find the slope AB

the slope is equal to

m=((y2-y1))/((x2-x1))

Substitute the values

m=((1-0.5))/((20-10))

m=((0.5))/((10))

m=0.05

Find the equation of the line with m and the point A

y-y1=m(x-x1)

y-0.5=0.05*(x-10)

y=0.05x-0.5+0.5

y=0.05x

therefore

the answer part 3) is

y=0.05x
1) Yes, the relationship in the table is proportional. If, when you've been walking for 10 minutes, you are 1.5 miles away from home, and when you've been walking for 20 minutes, you are 1 mile away from home, and when you've been talking 30 minutes, you are 0.5 miles away from home, then we can see that there is a proportion that happens here. For every 10 minutes you walk, you get 0.5 miles closer to your home.

2) We know that you've been walking 10 minutes already at the start of this problem, and we know that you walk at a steady pace of 0.5 miles every 10 minutes, so we just need to add 0.5 miles to our starting point to get the distance from the school to home, which makes it 2 miles away.

3) An equation representing the distance between the distance from school and time walking could be something like this:

t = 20d

Where t is the amount of time it takes to get home (in this case, t = 40 minutes) and d is the distance you can walk in 10 minutes (in this case, 0.5 miles)

The equation is lame, but that's the best I could do :\

nicole has a rectangular canvas that is 12 inches long and 10 inches wide.She paints a blue square in the center of the canvas.The sauare is 3 inches on each side. How much of the canvas is not painted blue?

Answers

First you add 10 with 12 which equals 22 the subtract 3 which is 19.So 19 inches of the canvas is not painted blue

In the Diagram Lines M And N are Parallel M < 2 = 150 degress, Find the Measure of the following angles <4=?
<6=?

Answers

The value of <4 = 150 and <6 = 150.

what are parallel lines?

The fundamental characteristics listed below make it simple to recognize parallellines.

  • Straightlines that are always the same distance apart from one another are called parallel lines.
  • No matter how far apart they are from one another, parallel lines can never intersect.

Given:

m<2 = 150

Now, from the Diagram

m<2 = m<4 (Corresponding angle)

m<4 = 150

and, m<6 = m<4 (VerticallyOpposite Angle)

m< 6 = 150

Hence, the value of <4 = 150 and <6 = 150.

#SPJ5

<4= 150
<6=150
because the angels are parallel <4 & <2 are the exact same measurements and because 6 is perpendicular to  <4 & <2 thus making it also 150 degrees

Solve 2(4x – 3) = 2(x + 2) + 8 for x. A. x = –2 B. x = 4 C. x = 3 D. x = –5

Answers

Answer:

C

Step-by-step explanation:

Solve the equation by applying the distributive property and combine like terms. Then use inverse operations to isolate the variable.

2(4x – 3) = 2(x + 2) + 8           Distributive Property

8x - 6 = 2x + 4 + 8                  Add 4 + 8

8x - 6 = 2x + 12                       Add 6 to both sides

8x = 2x + 12 + 6                      Add 12 + 6

8x = 2x + 18                            Subtract 2x from both sides

8x - 2x = 18                             Subtract 8x - 2x

6x = 18                                    Divide by 6

x = 3
