Answer:

11. 74

12. 8.5

13. 194

14. 56

15. the second one so 30.5 is more expensive

16. Manju walked further

Step-by-step explanation:

11. perimeter so add all the sides together

oh they are all perimeter so add the two numbers in each problem and then multiply that number by 2

60 vs 122 so the 30.5 is more expensive

280 vs 288 so manju walked more

brainliest would be greatly appriciated! Thanks!

Answer: Find an answer to your question Find 2 consecutive odd integers such that the sum of twice the larger integer and the smallest integer is 85.

Step-by-step explanation:

Answer:

The three integers are 12,13 and 14

Step-by-step explanation:

Let

x,x+1,x+2 be three consecutive integers.

Out of these, the smallest one is x and largest is x+2 as it comes at last in the integers.

So according to given statement

[tex]x+(x+1)+(x+2) = 4x-9[/tex]

This is a linear equation in one variable, which can simply be solved by using equality properties

[tex]x+x+1+x+2 = 4x-9\\3x+3 = 4x-9[/tex]

Subtracting 4x from both sides

[tex]3x+3-4x = 4x-9-4x\\-x+3=-9[/tex]

Subtracting 3 from both sides

[tex]-x+3-3 = -9-3\\-x = -12\\x = 12[/tex]

The smallest integer is 12.

The other integers are:

x+1 = 12+1 = 13

x+2 = 12+2 = 14

Hence,

The three integers are 12,13 and 14

x=distantce between  the Berto´s trains and the meeting point.

t=time where the trains meet up

⇒110 miles/h                                          ⇒85miles/h

[---------------------------E----------------------]-------------------------------------X

[............12 miles.......][........34 miles.....][------------ x ----------------------]

distance between Berto´s train and Eduardo´s train=

=12 miles+34 miles=46 miles.

S=d/t      ⇒d=S*t

S=seed

d=distance

T=time

Eduardo´s train;

46 miles+x=t*110 miles/h  ⇒x=t*110 miles/h-46 miles  (1)

Berto´s train;

x=t*85 miles/h  (2)

With the equations (1) and (2) we suggest this system equations:

x=t* 110 miles/h-46 miles

x=t*85 miles/h

we solve this system equiations :

t*110 miles/h-46 miles=t*85 miles/h

110t miles/h-85t miles/h=46 miles

25 t miles/h=46 miles

t=46 miles/25 miles/h=1,84 hour  (≈1 hour, 50 minutes, 24 seconds)

x=t*85 miles/h=156,4 miles

Solution: 1,84 hour

Answer:

x = -17

Step-by-step explanation:

y - y1 = m(x - x1)

y - 3 = 1/5(x - (-2))

y - 3 = 1/5(x + 2)

y - 3 = 1/5x + 0.4

y = 1/5x + 0.4 + 3

y = 1/5x + 3.4

Now we plug in y as 0 to find x

y = 1/5x + 3.4

(0) = 1/5x + 3.4

-3.4 = 1/5x + 3.4 - 3.4

-3.4 = 1/5x times 5

-3.4 times 5 = x

-17 = x

Answer:

Step-by-step explanation:

If we know the slope, we can solve for an unknown coordinate. First, let's review how to calculate slope.

Slope = Rise/Run (Change in y/Change in x)

In this case, we know the slope, so we will write out the slope formula. We will use the substitution method to solve this.

m = rise/run

rise = y2- y1 substituting ----> 3 - 0 = 3

run = x2 - x1 substituting ----> -2 - x = run

Now, we can return to the slope formula, as we now have enough information to solve.

1/5 = 3/R

To solve, we simply need to find the equivalent fraction of 1/5. We will use a proportion.

1R = 5 x 3

R = 15

Now that we know R, we can substitute it into the equation for run.

So, we now have:

15 = -2 - x

Subtracting -2 from both sides, gives us x = -17.

Finally, we must check our answer to make sure we are getting the correct slope when we calculate.

m = (3 - 0)/(-2 - -17)

m = 3/15 OR 1/5

Since. this matches the original slope we were given, we can be sure the answer is correct.

Step-by-step explanation:

Answer:

Slope: [tex]\frac{7}{2}[/tex]

Y-intercept: (0, 2)

Step-by-step explanation:

7x = 2y - 4

-2y = -7x - 4

y = [tex]\frac{-7}{-2}[/tex] x - [tex]\frac{4}{-2}[/tex]

y = [tex]\frac{7}{2}[/tex] x + 2

The slope is always the coefficient of x and the y-intercept is always the constant. It looks like (0, constant) when written in y-int form.

Answer:

slope (m) is 7/2 (aka 3.5) and y-int is (0,2)

Step-by-step explanation:

I don't really have an explanation, basically rearrange the problem so that to y is on the left but it would be 2y so divide the right side by two. I an explain further in depth if needed

Answer:  7.2 + L= 19.5

Answer:

logarithmic scale

The student might be able to graph these results clearly by taking the log of the values.

For given question,

A student has a range of values from 0.000001 to 1,000,000

We need to find the way so that the student will be able to graph these results.

We can write  0.000001 as [tex]1\times 10^{-6}[/tex]

[tex]\Rightarrow 0.000001=10^{-6}[/tex]

and 1,000,000 as [tex]1\times 10^6[/tex]

[tex]\Rightarrow 1,000,000=10^6[/tex]

If we take the log of these range values, then it would be,

[tex]\Rightarrow log(10^{-6})=-6[/tex]

and [tex]log(10^6)=6[/tex]

This means, the student might be able to graph these results clearly by taking the log of the values.
