Answer:

35.8

Step-by-step explanation:

                \frac{340.1}{9.5}  = 358

 We know that our answer can never be greater than 358 since the dividend

is 340.1 and the divisor is 9.5;

  Also,

  Both values are to one decimal places and we can use this to solve the problem;

  9 can divide 340 in about 37 place with a remainder of 7,

    So, it is appropriate to make the solution 35.8

2. Triangle ABC is equilateral and AB = 6x + 3, BC = 8x - 1,2. AB =
kherson [118]

Answer:

AB = BC = AC = 15

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent.

Equate any 2 sides and solve for x , that is

AC = AB , so

11x - 7 = 6x + 3 ( subtract 6x from both sides )

5x - 7 = 3 ( add 7 to both sides )

5x = 10 ( divide both sides by 5 )

x = 2

Then

AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus

AB = BC = AC = 15

• Given the function, f(x) = x3 – 5x2 + 9x – 45, determine the number of roots and identify them.
dezoksy [38]
x3 - 5x2 + 9x - 45 = 0
 It is a polynomial of degree three, therefore, it has three roots.
 For this case, what we can do is factorize to write the polynomial in an easier way and thus be able to find the roots.
 Factoring we have:
 (x - 5) (x ^ 2 + 9) = 0
 x = 5
 x = 3i
 x = -3i
 Answer: 
 three roots: 
 x = 5 
 x = 3i 
 x = -3i

yKpoI14uk [10]

on the sixth day   46 - 16 = 30  30/5 = 6 

or

16+5 =21

 21+5 = 26

 26 + 5 =31

 31+5 = 36

  36 +5 =41

 41 +5 = 46

Solve the system of equations by substitution.<br><br> y = 4x -1<br><br> 2x + 2y = 3
valkas [14]

Step-by-step explanation:

y = 4x - 1

2x + 2y = 3

2x + 2(4x - 1) = 3

2x + 8x - 2 = 3

10x = 3 + 2

x = 5/10

x = 1/2

y = 4x - 1

y = 4(1/2) - 1

y = 2 - 1

y = 1

(x,y) = (1/2 , 1)
