Answer:

27 28 29

Step-by-step explanation:

Let the first be n , and if they are consecutive then the next two numbers are n+1 and n+2.

n+(n+1)+(n+2)=84.

3n+3=84.

⇒3n=81.

⇒n=27.

Hence numbers are n,n+1,n+2→27,28 and 29

LenKa [72]

Answer:

The value of Y is either 0.8 cm less than the ideal length or 0.4 cm more than the ideal length.

Y = - 0.8 cm or Y = +0.4 cm

Step-by-step explanation:

ideal length = 0

X = - 0.2 cm

|X - Y| = 0.6 cm

X - Y = 0.6 or X - Y = - 0.6

X - Y = 0.6

-0.2 - Y = 0.6

-Y = 0.6 + 0.2

Y = -0.8 cm

X - Y = -0.6

-0.2 - Y = -0.6

-Y = -0.6+0.2 = -0.4

Y = 0.4 cm

The plot of the possible points on the number line that Y could be, is attached to this solution.

It is evident that the value of Y is either 0.8 cm less than the ideal length or 0.4 cm more than the ideal length.

Question 1 (Essay Worth 10 points) (01.02 MC) Part A: If (26)x = 1, what is the value of x? Explain your answer. (5 points) Part

katen-ka-za [31]

Answer:

See Explanation

Step-by-step explanation:

The question is not clear. However, I will treat the question as:

$(26)x = 1$

$(50)x = 1$

and:

$(2^6)^x = 1$

$(5^0)^x = 1$

Solving: $(26)x = 1$ and $(50)x = 1$

$(26)x = 1$

Divide both sides by 26

$x = \frac{1}{26}$

$(50)x = 1$

Divide both sides by 50

$x = \frac{1}{50}$

Solving $(2^6)^x = 1$ and $(5^0)^x = 1$

$(2^6)^x = 1$

Express 1 as 2^0

$(2^6)^x = 2^0$

Remove bracket

$2^{6x} = 2^0$

Cancel out 2

$6x = 0$

Divide both sides by 6

$x = \frac{0}{6}$

$x = 0$

$(5^0)^x = 1$

Express 1 as 5^0

$(5^0)^x = 5^0$

Cancel out 5^0

$x = 1$

What is the value of the expression -3xy + 4x when x=-4 and y=2?

snow_tiger [21]

Answer:

value of expression is 8

Step-by-step explanation:

Given Expression :- -3xy + 4x

We have to find the value of given equation when x = -4 and y = 2

We need to substitute the value of x and y in the given equation !

- 3xy + 4x = - 3 ( -4 ) ( 2 ) + 4 ( - 4 )

= 12 ( 2 ) - 16

= 24 - 16

= 8
