Which table best represents the steps to solve the equation 8 + x over 3 = 4? (5 points) Select one: a. Step Justification Step

1: x over 3 = 4 + 8 The same number +8 can be added to both sides of the equation Step 2: x over 3 = 12 Adding 8 and 4 on the right hand side Step 3: x = 12 ⋅ 3 The same number 3 can be multiplied on both sides of the equation Step 4: x = 36 Multiplying 12 and 3 on the right hand side b. Step Justification Step 1 x over 3 = 4 − 8 The same number −8 can be added to both sides of the equation Step 2: x over 3 = −4 Adding −8 and 4 on the right hand side Step 3: x = −4 ⋅ 3 The same number 3 can be multiplied on both sides of the equation Step 4: x = −12 Multiplying −4 and 3 on the right hand side c. Step Justification Step 1: x over 3 = 4 − 8 The same number − 8 can be added to both sides of the equation Step 2: x over 3 = −4 Adding 4 and −8 on the right hand side Step 3: x = − 4 − 3 The same number 3 can be subtracted from both sides of the equation Step 4: x = −7 Simplifying −4 −3 d. Step Justification Step 1: x over 3 = 4 − 8 The same number − 8 can be added to both sides of the equation Step 2: x over 3 = −4 Adding 4 and −8 on the right hand side Step 3: x = − 4 − 3 The same number 3 can be subtracted from both sides of the equation Step 4: x = −7 Simplifying −4 −3

The answer is -1/8 because u  multiply  both numerators by each other and both deminators by eachother and you get 15\120 then  u  simplify you do 15 divided by 15 and get 1and then 120 divided by  15 and get 8 and u get 1\8 as your answer

Help urgent In a class of 35 students 15 of them have cats 16 have dogs 3 hangs none how many probability does have both
dalvyx [7]

Answer:

9/25

Step-by-step explanation:

Number of student who has cat , dog = 25 - 3 = 22

Number of students who has cat and dogs = (15 + 16) - 22

                                                                       = 31 - 22 = 9

Number of students who has only cats = 15 - 9 = 6

Number of students who has only dogs = 16 - 9 = 7

P(Cat & dog) = 9/25

36/100 simplified in simple form
Ludmilka [50]

Hello from MrBillDoesMath!


Answer:  9/25


Discussion:

My first observation is that both 36 and 100 are even numbers, so let's divide each by 2.

36/100 = 18/50

Again, 18 and 50 are even numbers so let's divided each by 2

= 18/50 =  9/25

While I didn't write it out, my statement "divide them by 2" is really this:

36/100 =   ( 36/2) / (100/2)  = (18) /50 = ( 18/2) / (50/2) = 9/25

Confusing, isn't it!

A shorter, but equivalent, approach is to divide the numerator and denominator by 4.



Regards, MrB.
