Find slope for 7x-2y=0.2
$7x - 2y = 0.2$

Answers

Answer 1

Answer:

Answer:

slope = -7/2

Step-by-step explanation:

To find the slope, we will solve the equation for y.

7x-2y=0.2

Subtract 7x from each side.

7x-7x-2y=-7x+0.2

-2y = -7x+0.2

Then we need to divide each side by -2

-2y/-2 = -7x/-2 + 0.2/-2

y = -7/2 x -0.1

This is in the form y= mx+b where m is the slope and b is the y intercept.

So the slope is -7/2 and the y intercept is -0.1

Describe and correct the error in finding the product
2/5×3/10=6/50=3/25

Answers

Answer: There is not error in finding the product. The result is: $=(3)/(25)$

Step-by-step explanation:

1. You have the following multiplication shown in the problem above:

$(2)/(5)*(3)/(10)$

2. To solve it you must multiply the numerators and multiply the denominators, as you can see below:

$(2*3)/(5*10)=(6)/(50)$

3. When you simplify the product, you obtain the following result:

$=(3)/(25)$

The constant is same amount of butter, same amount of popcorn , same temperature and so on and so forth.

What is 1 7/8 Times 2 1\3

Answers

We need to convert the mixed fractions into improper fractions.

1*8 = 8
8+7 = 15

15/8

2*3 = 6
6+1 = 7

7/3

Now we can finish and multiply

$(15*7)/(8*3)$

15*7 = 105
8*3 = 24

Simplify 105/24

105/24

24*4 = 96

105 - 96 = 9

4 is the whole number, and 9 is the numerator.

4 9/24

Simplify that,

9/3 = 3
24/3 = 8

4 3/8

Answer: $4(3)/(8)$

1 7/8* 2 1/3
= 15/8* 7/3
= 35/8
= 4 3/8

The final answer is 4 3/8~
