A runner sprints 100m at 8m/s what is time?

Answer:

Let the number be x

According to the question,

6x -7 = 35

=> 6x = 35 + 7

=> x = 42/6

=> x = 7

The solution to the equation is x = 7.

We have,

Let's assume the unknown number is represented by the variable 'x'.

- Translate the given information into an equation:

6x - 7 = 35.

- To isolate the variable 'x', start by adding 7 to both sides of the equation:

6x - 7 + 7 = 35 + 7.

- Simplify:

6x = 42.

- Next, divide both sides of the equation by 6 to solve for 'x':

(6x)/6 = 42/6.

x = 7

Therefore,

The solution to the equation is x = 7.

Answer:

2 1/7

Step-by-step explanation:

Answer:

2 1/7, is 15/7(improper fraction) as a mixed fraction, and

1 8/7 is an improper mixed fraction equivilent to 2 1/7.

Step-by-step explanation:

15/7 = 7/7 + 7/7 + 1/7 = 1 + 1 + 1/7 = 2 1/7

1 8/7 = 1 + 8/7 = 1 +7/7 + 1/7 = 1 + 1 + 1/7 = 2 1/7

Answer:

No solution.

Step-by-step explanation:

Write the expression, combine like terms, and distribute.

-1+30x+24=6(5x+4)

30x+23=30x+24

Get rid of the variable first because they're both 30x (it makes it a lot easier).

30x+23=30x+24

-30x      -30x

23=24

23 is not equal to 24. When this happens, it means there is no solution, and that's just the answer.

Answer:

y = - [tex]\frac{1}{3}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m= [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 7) and (x₂, y₂ ) = (- 3, 6)

m = [tex]\frac{6-7}{-3+6}[/tex] = [tex]\frac{-1}{3}[/tex] = - [tex]\frac{1}{3}[/tex] , thus

y = - [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 3, 6 ), then

6 = 1 + c ⇒ c = 6 - 1 = 5

y = - [tex]\frac{1}{3}[/tex] x + 5 ← equation of line

Answer:

Step-by-step explanation:

f(x) = –|x + 3| is a case of the absolute value function

f(x) = -|x - {a}| + c, where (a, c) is the vertex.  Comparing them, we see that

the value of a must be -3 and that of c must be 0.

Thus, the vertex of the graph is at (-3, 0), and the graph opens up; it looks like a "v" shape.

Step-by-step explanation:

[tex]2(x+5)-3 =15[/tex]

Using the distributive property in the LHS we get

[tex]2x+10-3 =15[/tex]

[tex]2x+7=15[/tex]

Now add -7 both sides. So we have the subtraction property of equality.

[tex]2x+7+(-7)=15+(-7) \text{ This is what I meant for add}[/tex]  

[tex]2x+7-7=15-7[/tex]

[tex]2x=8[/tex]

Now divide both sides by 2. So we have the division property of equality

[tex]\dfrac{2x}{2} =\dfrac{8}{2}[/tex]

[tex]x=4[/tex]

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

These type of problems could be a little tricky so I'll explain this one as I go.

So the first step I would do is to multiply the 8 in both sides so you end up with...[tex]x+11=-24[/tex]

After that it should be easier and you'll go at it normally by subtracting the 11 in both sides and that should leave you with the answer of [tex]x=-35[/tex]

Answer:

x=9

Step-by-step explanation:

-9x+1=-80

To eliminate the one, you subtract one from both sides.

That gives you:

-9x=-81

Then you divide both sides by negative nine to get x by itself.

x=9
