Find the missing number so that the equation has infinitely many solutions. -4x+20=blank x+20

Answers

Answer 1

Answer:

0

Step-by-step explanation:

20 cancels itself out so

-4x = x

-4x - x = 0

-5x = 0

divide both sides by -5x

x= 0 but we don't write it out

Answer 2

For the equation -4x+20 to have infinite solution , it should be equal to

-4x+20 = -4x+20 , so the blank value is -4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be -4x+20 = blank x + 20

Now ,

If the lines are coincident and have the same y-intercept, an endless solution can be generated.

The two lines with the same y-intercept and slope are the same line.

If the two lines share the same line, the system will produce an infinite solution. As a result, if the system of equations contains an infinite number of solutions, the system is consistent.

So , Both the equations should be equal for it to have infinite solutions

Therefore , -4x+20 = -4x+20

Hence , the value of the blank is -4

Two times the complement of an angle is 23 less than the supplementary of the angle. What is the measure of the angle?

Answers

Answer:

Step-by-step explanation:

Let the angles be x and y

If the two angles are complementary then their sum is 90 i.e x+y = 90

x = 90-y

If the two angles are supplementary, then their sum is 180 i.e x+y = 180

x = 180-y

If two times the complement of an angle is 23 less than the supplementary of the angle, this is written as;

2(90-y) = (180-y)-23

180-2y = 157-y

-2y+y = 157-180

-y = -23

y = 23

Hence the angle is 23°

Marrisa added 1.56 and 13.47. She got 29.07. What mistake could Marrisa have made? She forgot to move the decimal point to the left after she added. She lined up the front numbers instead of the decimal places. She lined up the last numbers instead of the decimal places. She didn’t carry correctly between place values.

Answers

without an explanation your answer is (B) She lined up the front numbers instead of the decimal places.

if you need an explanation here:

________________________________________

For a problem with a decimal in the numbers, you ALWAYS have to line them up or your answer will be incorrect.

She should have put: 13.47

                                 +  1.56

                                    15.03

therefore, 15.03 would have been her correct answer. :-)

Find the inverse of the following function g(x) = 2x+10/4

Answers

Answer:

Step-by-step explanation:

To find the inverse of the function you need to swap x and y

g(x)=y so therefore if you switch x and y, you get

x= 2y+ 10/4

Next, you need to get all of the values on the y side over to the x side. To do this you need to subtract 10/4 from the y side of the equation.

x-10/4=2y+10/4-10/4

The end product of this should be... (This is not your answer)

x-10/4=2y

Now you need to get rid of the 2 on the y side. To do this you need to divide both sides of the equation by 2

2/x-10/4=2y/2

So your answer is...

x-10/4 over 2 = y

OR

2/x + 5/4 = y

Ari is jogging at an average rate of 2.25 meters per second. Find the time it will take him to jog 270 meters.

Answers

Answer:

120 seconds/2 minutes

Step-by-step explanation:

divide the distance (270 m) by the rate (2.25 m/s) and you have 270/2.25 = 120 seconds, or 2 minutes.

It will take Ari 120 seconds to jog 270 meters.

To find the time it will take Ari to jog 270 meters at an average rate of 2.25 meters per second, we can use the formula:

Time = Distance / Rate

where:

Distance = 270 meters

Rate = 2.25 meters per second

Time = 270 meters / 2.25 meters per second

Time = 120 seconds

Therefore, it will take Ari 120 seconds to jog 270 meters.

George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL. What is the volume of the object?

Answers

Answer: 20 mL

Step-by-step explanation:

According to Archimedes, the upward force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.

i.e. weight of the object = weight of the fluid displayed

Given: George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL.

So, the volume of the object = New volume - Original volume

= 45 mL - 25 mL

= 20 mL

Hence, the volume of the object =20 mL

19. What is the coordinate of the midpoint of the segment formed by the two points you found in Exercises 17 and 18?

Please explain

Answers

Answer:

0

Step-by-step explanation:

To find the coordinate of the midpoint of segment QB, first, find the distance from Q to B.

QB = |4 - 8| = |-4| = 4

The coordinate of the midpoint of QB would be at ½ the distance of QB (½*4 = 2).

Therefore, coordinate of the midpoint of QB = the coordinate of Q + 2 = 4 + 2 = 6

OR

Coordinate of B - 2 = 8 - 2 = 6

Coordinate of the midpoint of QB = 6

Coordinate of W = -8

Coordinate of A = 0

distance from W to A (WA) = |-8 - 0| = |-8| = 8

The coordinate of the midpoint of WA would be at ½ the distance of WA = ½*8 = 4.

Therefore, coordinate of the midpoint of WA = the coordinate of W + 4 = -8 + 4 = -4

Or

Coordinate of A - 4 = 0 - 4 = -4

Coordinate of the midpoint of WA = -4

Now, let's find the midpoint between the two new coordinates we have found, which are -4 and 4

Distance of the segment formed by coordinate -4 and 4 = |-4 - 4| = |-8| = 8

Midpoint = ½*8 = 4

Coordinate of the midpoint = -4 + 4 = 0

Or

4 - 4 = 0
