10/12 simplified 5/6

Answer:

A) [tex]\frac{5}{6}[/tex]

Step-by-step explanation:

So solve, change the sign into multiplication and use the reciprocal of the second number.

To find the reciprocal,  flip the numerator and the denominator.

The reciprocal of 4/5 is 5/4.

So you have [tex]\frac{2}{3}[/tex]×[tex]\frac{5}{4}[/tex]

Multiply like a normal expression.

You get 10/12, which can be simplified to [tex]\frac{5}{6}[/tex]

Point R is at (2, 1.2) and Point T is at (2, 2.5) on a coordinate grid. The distance between the two points is ____. (Input numbers and decimal point only, such as 8.2.)

Answers

Answer:

we can see that the x or the first number in both are 2 so there is no distance there, where there is a distance is the y which to find out we can just do 2.5-1.2=1.3

the distance between the two points is 1.3

1.3 that is the answer yw

if all functions are relations, are all relations functions? Explain your answer

Answers

Answer:

No, because some relations are not functions. Relations are equations that begin with x=, and let's say x=5.

This is not a function because if you graph this line, it is vertical, and functions can't share the same x coordinate point (input) with other y coordinate points (output). There must be one output for every input, meaning that this relation is not a function.

Step-by-step explanation:

No, just because functions are relations Doesn’t mean it’s the same for the other

Select all the equations that have {4} as its solution set. 5 + 2x = 3x + 37−x=12x79−3x=12x+19x2+3=10x−21


5 + 2x = 3x + 3

7−x=12x

79−3x=12x+19

x2+3=10x−21

Answers

Answer:

Option 3 (79−3x=12x+19)

Step-by-step explanation:

When replacing x with 4 you will get the answer 67 = 67, which is true! The other three options are not true when replacing x with 4.

Equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

Given that, the equations that have {4} as its solution set.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

1) Solution of an equation 5 + 2x = 3x + 3 is

3x-2x=5-3

⇒x=2

2) Solution of an equation 7−x=12x is

7−x=12x

⇒12x+x=7

⇒13x=7

⇒x=7/13

3) Solution of an equation 79−3x=12x+19 is

12x+3x=79-19

⇒15x=60

⇒x=4

4) Solution of an equation x²+3=10x−21 is

x²+3=10x−21

⇒ x²-10x+24=0

⇒ x²-6x-4x+24=0

⇒ x(x-6)-4(x-6)=0

⇒ (x-6)(x-4)=0

⇒ x=6 or 4

Therefore, equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.

The sum of 5.5 and twice a number is -10
What is the number?

n = 7.75

n=2.125

n= -7.75

n=-2.125

Answers

The answer is n= 7.75.

Answer:

n=-7.75

Step-by-step explanation:

Based on the given conditions, formulate: 5.5+2×X=-10

Rearrange unknown terms to the left side of the equation:2x=-10-5.5

Calculate the sum or difference:2x=-15.5

Divide both sides of the equation by the coefficient of variable:x=-15.5/2

Multiply both the numerator and denominator with the same integer:-155/20

Cross out the common factor:-31/4

get the result:  -7.75

Answer: -7.75
