Use the numbers 8,6, and 2 and one operation to write an expression that includes an exponent and has a value of 8. Use each num

omeli [17]

$6 + 2^1 = 8$ is the expression that includes an exponent and has a value of 8

Solution:

Given that, we have to use numbers 8, 6, and 2 and one operation to write an expression that includes an exponent and has a value of 8

We are asked to use each number only once

Given conditions:

We have to use an operation and an exponent

The exponent corresponds to the number of times the base is used as a factor.

We have to get 8 as result

Since 6 is higher number, we can use exponent for 2

We can raise 2 to power of 1

The required expression:

$6 + 2^1 = 8$

Here we have the satisfied the given condition of using exponent and an operation ( addition is used ) and numbers are used only once

Find the value of x. (8x - 11) 5x° (2x+6)°

ira [324]

Answer: x=37/3

Step-by-step explanation:

8x-11+5x+2x+6=180 ==> three angles of a triangle add up to 180 degrees

8x+5x+2x-11+6=180

13x+2x-5=180

15x-5=180

15x=185

x=185/15

x=37/3

13. The mean score of Vasu in 3 tests is 46 marks. How many marks should he score in the fourth test so that the mean score of t

Katena32 [7]

Step-by-step explanation:

Let,

Marks in fourth test = x

We know that

Mean = Sum of observation/Total observation

=> 46 = Sum/3

=> 46 × 3 = Sum

=> 138 = Sum

Now,

=> 50 = Sum of three observation + x/4

=> 50 = 138 + x/4

=> 50 × 4 = 138 + x

=> 200 = 138 + x

=> 200 - 138 = x

=> 62 = x

Hence,

he should score 62 marks in fourth test

abruzzese [7]

Answer: i think you are supposed to subb in the x and h for something i just dont know what it is im not that smrt sorry i would thing it is 4 for x then the one would turn negative because in the equation it is subtraction so just do 4(4)^2+4-1 for the first one

the second one just do the same thing sub in the same numbers so it would be 4(4+1)-4(4)/1 i think it will get your answer brainliest plz
