Answer:

x=4

Step-by-step explanation:

1) first write it down --> 11x-2+9x+1=19x+3

2) then combine like terms on the left side of the equation. --> 20x-1=19x+3

3) Then subract 19x on both sides --> x-1=3

4) After add 1 to both sides --> x=4

Answer:

It's the second option

Step-by-step explanation:

The x moves over to the right for a positive 3

The y moves up for a positive 4.

Hope this helps! :)

Answer:

12/20    21/35    30/50

Step-by-step explanation:

These are all equivalent fractions to 3/5.

Hope this helps!

The fractions that are equivalent to 3/5 are C) 12/20, D) 21/35, and E) 30/50.

To determine which fractions are equivalent to 3/5, we need to find fractions that can be simplified to the same value.

The fraction 3/5 cannot be simplified further because 3 and 5 have no common factors other than 1.

Let's check each option:

A) 8/10 can be simplified to 4/5, which is not equivalent to 3/5.

B) 8/15 cannot be simplified further, but it is not equal to 3/5.

C) 12/20 can be simplified to 3/5, which is equivalent to 3/5.

D) 21/35 can be simplified to 3/5, which is equivalent to 3/5.

E) 30/50 can be simplified to 3/5, which is equivalent to 3/5.

Therefore, the fractions that are equivalent to 3/5 are C) 12/20, D) 21/35, and E) 30/50.

Answer:

Longer piece: 50 in

Shorter piece: 10 in

Step-by-step explanation:

Lets make the shorter piece = x

Leta make the longer piece = 5x

Since the longer piece is 5 times the shorter, this is why we put 5x, because 5 times the shorter. We also have to find the two lengths of the pieces which in total equals 60 in.

x + 5x = 60 in

If we substitute the x to 10:

10 + 50 = 60 in

10 in = shorter length

50 in = longer length

1 time

Answer:

10

Step-by-step explanation:

We need to find how many trips it will take to transport 58 cars

The explanation is simple:

58 / 6 = 9.6 repeating

So we round that quotient up to 10.

So the transport truck will need to take 10 trips to transport all 58 cars.

Answer:

  17x^2 -5x

Step-by-step explanation:

"Simplify" in this context means "combine like terms." It can help to group the terms with the same variables.

  -9x+9x^2+8x^2+4x

  = 9x^2 +8x^2 -9x +4x

  = x^2(9+8) +x(-9+4)

  = 17x^2 -5x

Answer:

2.5 miles

Step-by-step explanation:

We know that: time = distance/speed

Now, if the distance of the school from Jonathan's home is y.

At speed of 15 mph, Jonathans time is; time = y/15 hours

At 25 mph, his mother's time was;

time = y/25 hours

We are told that Jonathan was 1 mile from home when he saw his mother.

Thus means that difference in time is;

Time difference = 1/15 hours

Thus;

y/15 hours - y/25 hours = 1/15 hours

Multiply through by 75 to get;

5y - 3y = 5

2y = 5

y = 5/2

y = 2.5 miles

Vota Trump

Step-by-step explanation:

Answer:

The answer would be: -0.01

Step-by-step explanation:

1) State what is given

AM = 5x -2 and MB = 2x +19

2) Make an equation that can satisfy the problem

AM + BM = AB

This is the equation, because if I am to put this on a line,

A                        M                         B

-_____________-_____________-

You can see that is you combine the lengths AM and BM you can find the total length of  AB.

A                        M         +           M                        B    

-_____________-          +           -_____________-

(M point is actually one point, but I am trying to show that if the line were to be cut in half, then put back together you get you full length, which is AB)

3) Substitute

(5x - 2) + (2x + 19) = AB

4) Now Solve!

5x - 2 + 2x + 19 = AB

(Rearrange to combine like terms)

5x + 2x + 19 - 2 = AB

7x + 17 = AB

(That is your equation to find AB! But they want the specific length)

So...

We solve it!

7x = -17

(By moving the 17 to the other side of the = sign, it becomes negative)

7x = -17

7       7

(Dividing both sides by 7 in order to get x alone)

x = -2.43

(I rounded to the hundredths place)

Now substitute that into x into you original equation)

5(-2.43) - 2 + 2(-2.43) + 19 = AB

-12.15 - 2 - 4.86 + 19 = AB

-14.15 - 4.86 + 19

-19.01 + 19 = -0.01

= -0.01

(I believe this would be the answer, but it doesn't seem to fit right, so please understand, that if this is wrong, I AM SO SORRY ;-;)

(I tried my best on this problem, but I bet it isn't the answer, so if I get this wrong tell me so that I can remove it! :)

Answer:

  77.5°

Step-by-step explanation:

Let s represent the measure of the second angle. Then the first angle is s+25. These two angles are supplementary, so their sum is 180:

  (s+25) +s = 180

  2s = 155

  s = 77.5

The measure of the second angle is 77.5°.

The value of the common solution to the system of equation is (2,-3).

The system of equation is set of equations which have a common solution.

The figure shows the graph of two equations, these equations are a straight line function and the common solution is represented by a point in the image.

The solution of the system of equation can be obtained both by solving using substitution method and even by plotting the graph and finding the  intersection point.

The system of equation is,

y = 2x - 7

y = -x -1

The value of y from equation 2 will be substituted in equation 1

-x -1 = 2x -7

3x = 6

x = 2

Substituting this value in equation 2

y = -2 -1

y = -3

The value of (x,y) is (2,-3)

The graph is plotted and the intersection of the line is at (2,-3)

Answer:

13

Step-by-step explanation:

6 1/2 x 6 1/2

or

6.5 + 6.5 =13

6+6=12

0.5 + 0.5=1

12+1=13

the double of 6 1/2 is 26/2, which simplifies to 13

To find the double of 6 1/2, we first convert the mixed number 6 1/2 to an improper fraction. We multiply the whole number (6) by the denominator (2), which gives us 12. Then, we add the numerator (1) to get 13. So, 6 1/2 as an improper fraction is 13/2.

To double this fraction, we multiply the numerator (13) by 2, resulting in 26. The denominator remains the same (2). Therefore, the double of 6 1/2 is 26/2, which simplifies to 13. In other words, doubling 6 1/2 gives us the whole number 13.
