Solve. -2(6 - 20n) = 20(2n - 3)a. 40
b. 36
c. no solution
d. all real numbers

Answers

Answer 1

Answer:

The equation -2(6 - 20n) = 20(2n - 3) has no solution.

Hence the correct option is C.

Given is an equation -2(6 - 20n) = 20(2n - 3), we need to solve it for n,

Let's solve the equation step by step:

-2(6 - 20n) = 20(2n - 3)

First, distribute the -2 on the left side and the 20 on the right side:

-12 + 40n = 40n - 60

Next, let's move all the terms with "n" to one side of the equation:

-12 + 40n - 40n = 40n - 40n - 60

-12 = -60

Now, we can see that the equation is inconsistent, as there are no values of "n" that satisfy this equation.

Therefore, the correct answer is:

c. no solution

Answer 2

Answer: -2(6-20n) = 20(2n-3)
-12 + 40n = 40n - 60
40n = 40n - 60 + 12
40n - 40n = 60 + 12 (dont minus 40n - 40n yet, we can factorise it)
n(40-40) = 60 + 12
n = (60 + 12)/(40-40)
n = 60 + 12/ 0

Therefore no solution as we cannot divide by 0

Answers

Total number of numbers = 12

Total number of 4 or 6 = 2

P( 4 or 6) = 2/12 = 1/6

Answer: 1/6

∠1 and ∠2 form a linear pair. If m∠1 = 5x + 9 and m∠2 = 3x + 11, find the measures of both angles.

Answers

Answer:

∠1 =109

∠2= 71

Step-by-step explanation:

if they are a linear pair that means they must both (when added together) equal 180 degrees, so this means we can add them and set them equal to 180!

8x+20=180

8x=160

x=20

then we just input them!

m∠1 = 5(20) + 9 = 109

m∠2 = 3(20) + 11 = 71

if there are 15 work days until the day she begin tio sell the basket how many basket will she have to sell

Answers

so she has 13 baskets over from last year
then y- intercept would be 13
and make 12 more each day
so the slope would be 12
and there is 15 work days
y= 12x + 13
y= 12(15) +13
y=180+13
y=193
just remember the linear equation then you will get to understand the problem

You drive 1400 miles in 3.5 days. You drive an equal number of miles each day. How many miles do you drive each day.

Answers

Answer:

400 Miles Per Day

Step-by-step explanation:

If you drive an equal amount of miles each day, you know the total miles driven will be the amount of miles per day. Therefore $(1400 Miles)/(3.5 Days) = 400 (Miles)/(Day)$
