What is the process for finding the answer to: 0.2x - 1 = -1?

2 answers:

7 0

Add one to each side which gives you 0.2x=0
Then divide each side by 0.2 so that the 0.2s on the same side cancel out so you’re left with 0/0.2 so the answer would be x= 0

Step-by-step explanation:

0.2x - 1 = -1

first write out the problem

0.2x - 1 = -1

+1 +1 Add 1 to both sides to remove the -1 from the same side as x

0.2x = 0

/0.2 /0.2 Divide the number being multiplied with x to get x alone

0/0.2 = 0

x = 0 Now you have the answer.

find the scale, k, of H(3,4) if H'(9,12) after going through the transformation (x,y) ---> (kx,ky) centered at the origin

stiks02 [169]

The value of scale k is 3

Step-by-step explanation:

In order to find the scale , we can either divide the coordinates of H' by the original point or compare both the points to find the original ordered pair.

Given

H(3,4)

H'(9,12)

The coordinates of H are multiplied with some integer k to form H'

So,

For x-coordinate:

3k = 9

k = 9/3 = 3

For y-coordinate:

4k = 12

k = 12/4 = 3

Hence,

The value of scale k is 3

Factor the binomial using its GCF: 10x-15x^4

Igoryamba

Answer:

5x(2 - 3x³)

Step-by-step explanation:

10x-15x^4

The GCF( Greatest Common Factor) of 10x-15x^4 is 5x

Solve:

10x/5x = 2

-15^4/5x = -3x³

Final answer is

5x(2 - 3x³)

Check

5x(2 - 3x³)

distribute

5x(2) + 5x(-3x³)

10x - 15x^4

Solve for n. 1/2n+3/4n=12

sveta [45]

First you add 1/2 and 3/4:
5/4n

5/4n = 12 so you divide both sides by 5/4
That gives you the answer of n= 9.6.

Hope this helped :)

It took 3/4h to complete 1game of cards.How many games can be completed 2 1/4h?

Crank

I would prefer to solve this in a decimal form
I will show this to u in 2 ways
1:.75::X:2.25
(1*2.25)/.75x
2.25/.75x
X=3

2.25/.75=3
when we divide the number of hours played by hors for one game we get the number of games that could be played

Gavin drove 85 miles on 10 gallons of gas.How many miles can gavin drive on 25 gallons of gas?

bixtya [17]

Answer:

212.5 miles on 25 gallons.

Step-by-step explanation:

Set up a proportion

85 miles on 10 gallons

x miles on 25 gallons.

85/10 = x / 25 Multiply both sides by 25

85*25 / 10 = x Simplify the left

2125 / 10 = x

x = 212.5 miles in 25 gallons.
