Answer:

 x = 17/2 = 8.500

Step-by-step explanation:

Equation at the end of step  1  :

 2 • (x - 5) -  7  = 0  

Step  2  :

Equation at the end of step  2  :

 2x - 17  = 0  

Step  3  :

Solving a Single Variable Equation :

3.1      Solve  :    2x-17 = 0  

Add  17  to both sides of the equation :  

                     2x = 17

Divide both sides of the equation by 2:

                    x = 17/2 = 8.500

When Wesley began first grade, he was 44 3/8 inches tall. At the end of the year, he was 45 1/4 inches tall. How much had Wesley
nikitadnepr [17]
So start:44 3/8 end: 45 1/4
so 44 3/8+x=45 1/4
subtract 44 3/8 from both sides
x=grow=45 1/4-44 3/8
so convert to fractions
45=180/4
45 1/4=181/4

44=352/8
44 3/8=355/8
181/4=362/8
x=362/8-355/8=7/8 inch he grew

Which of the following represents the zeros of f (x)=x^3-2x^2-6x+12
lianna [129]
F(x) = x^3 - 2x^2 - 6x + 12 = 0

lets try  substituting some of the factors of 12:-

f(2)  = 8 - 8 -12+12 = 0    So one  zero is x = 2 Answer

Dividing f(x) by (x - 2) we get:-

x^2 - 6   so the other 2 zeros are  sqrt6 and - sqrt6 or 2.45 and -2.45 to the nearest hundredth  Answer

Ackie got 3 wrong out of 20 questions on her social studies quiz.What percent did she answer correctly on the quiz
taurus [48]

Answer:

85%

Step-by-step explanation:

If she got 3 wrong then it means she got 20-3 right, so she got 17 questions right.

From there we get the fraction: 17/20

To make the a percentage we times both the top and bottom by 5 (because 20 x 5 = 100)

By doing that we get 17x5/20x5

= 85/100

That is equal to 85%
