The word as an equation 2 1/2 is the same as the sum of the number w and 1/2 is 2 1 / 2 = w + 1 / 2

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Therefore, the word as an equation 2 1/2 is the same as the sum of the number w and 1/2 is as follows;

The sum of the number w and 1/2 is w + 1 / 2.

Then, the word as an equation 2 1/2 is the same as the sum of the number w and 1/2 is

2 1 / 2 = w + 1 / 2

Step-by-step explanation:

Because when you take 7.429 another nine rounds the 2 and it is higher than 5 so it would make that 7.43 and for C 7.433 the second 3 is lower than 5 so it doesnt change anything, since 5 and above give it a shove and 4 and below let it go, so I believe its A and C

Answer:

x=132

Step-by-step explanation:

Hey There!

The angle that is equal to 48 and angle x are supplementary angles meaning that they will add up to equal 180

so to find x we subtract 48 from 180

180-48=132

therefore x=132

The value of x will be;

⇒ x = 132°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The triangle is shown in figure.

The interior angles are;

⇒ 60°, 72° and 48°

Now,

We know that;

The sum of two opposite interior angle of the a triangle is equal to the exterior angle of the triangle.

So, We get;

⇒ x = 60° + 72°

⇒ x = 132°

Thus, The value of x = 132°

Answer:

  45

Step-by-step explanation:

The equation is that of a parabola in vertex form.

  y = a(x -h)^2 +k

where 'a' is the vertical scale factor and (h, k) is the vertex.

Comparing this to the given function, you find ...

  a = -5

  h = 1

  k = 45

The negative value of 'a' tells you the parabola opens downward, so the y-value of the vertex is the maximum value of the function: 45.

Answer:

To find the absolute value of an negative number, just take away the negative sign

The absolute value of a number can NEVER be negative

Step-by-step explanation:

For example, to find the absolute value of -22, it would be 22, since it is 22 points away from zero. To find the absolute value of -99.9, it would be 99.9.

A negative number is NOT always the absolute value of a number.

For example, the absolute value of 34 is, 34. If you plot it on a number line, it is 34 points away from zero, therefore proving a negative number is NOT always the absolute value of a number.

The absolute value of a number can NEVER be negative.

Answer:

The absolute value of a number is always POSITIVE! To find the absolute value, all you need to do is take away the negative sign!

Answer:

I think there is an error in the question, I assume it reads:

4x+2y=20

x+3y=50

If not, please make appropriate corrections to the question.

Answer: x=-4, y=18

Step-by-step explanation:

4x+2y=20

Simplify, divide by two,

2x+y=10.....................(1)

x+3y=50....................(2)

Multiply (2) by 2

2x+6y=100 ....................(2a)

Subtract (1) from (2a)

2x+6y - (2x+y) = 100 - 10

5y = 90

y=18..............................(3)

Substitute (3) into (1)

2x+(18)=10

2x = 10-18 =-8

x=-4  ............................(4)

Substitute (3) and (4) into (1) for verification

2x+y = 2(-4)+18 = 18-10 = 10   checks.

Substitute (3) and (4) into (2) for verification

x+3y=-4+3(18) = -4+54 = 50  checks.

Have a nice day!

The time it will take for the coin to hit the ground is 5 seconds for the given function.

Displacement and distance are terms used to describe how an object or person moves, but they have different meanings.

No matter where anything starts or ends, distance describes how much ground it has travelled. It is a scalar quantity with units like metres, kilometers, miles, etc. for measurement.

On the other hand, displacement describes a change in an object's or a person's location from their original position to their end position, including direction. Since it has both magnitude (the distance) and direction, it is a vector quantity. Displacement can be positive or negative depending on the direction of movement and is measured in units like metres, kilometers, miles, etc.

The given equation is  y=-5t² +125.

When the coin hits the ground the value of y = 0 thus,

y = -5t² + 125

0 = -5t² + 125

5t² = 125

t² = 25

t = ±5

Hence, the time it will take for the coin to hit the ground is 5 seconds.
