Answer:

the line is at a 6.9 degree angle

Step-by-step explanation:

when the y = 69 the x = 420

Answer:

The answer is y = 1/8x

Step-by-step explanation:

Slope-intercept form is y = mx + b, with m being the slope and b being the y-intercept.

In this graph, we can see the line intersects the y-axis at point (0, 0). This means the y-intercept is 0, so we don't have to add it in the equation.

To find the slope, we use the formula m = (y₂ - y₁)/(x₂ - x₁) using two coordinate points on the line: (0, 0) and (8, 1).

Substituting it in the formula, we get m = (1 - 0)/(8 - 0), which simplifies to 1/8.

Putting this information into slope-intercept form, we get that the equation of the line in slope-intercept form is y = 1/8x.

You divide 12 and 90 with 2 you can’t divide it anymore because you can’t divide 6 and 45 with the same answer.
I hope you understand a little better

Answer:

2/15  12/90=2/15

both 12 and 90 are multiples of 6 so we divide both of this by 6

so 12 divided by 6 is 2 and 90 divided by 6 is 15

so simpiflied 12/90 is 2/15

PLEASE HELP ME WITH THIS
Please put an easy explanation for me to understand how to do this on my own.

Answers

Answer:

Step 1: Simplify both sides of the equation.

2w=1/4

Step 2: Divide both sides by 2.

2w/2=1/4/2  

Answer:

w=1/8

Answer:

So what you have to do is that first, you simplify both sides of the equation.

(2w = 1/4). Then you divide both sides by 2, (2w / 2 = 1/4 / 2). So after you do that, your left with w = 1/8. So W is equal to 1/8.

Answer:

Apply the distributive property to the left-hand side of the inequality.

Step-by-step explanation:

Using PEMDAS, what you need to do first is clear!

P -> parentheses ( distribute, clear them out, etc. )

E -> exponents

M -> multiplication

D -> division

A -> addition

S -> subtraction

Going in order, you would apply the distributive property first to clear out the parentheses.

Jake's apple farm has 228 apple trees. Last year, 182,172 apples were produced at Jake's apple farm. If each apple tree produced the same amount, how many apples did each tree produce?

Answers

Answer:

799 apples were produced by each tree.

Step-by-step explanation:

182,172 apples evenly produced by 228 trees.

182,172 apples ÷ 228 trees = 799 apples per tree

799 apples • 228 trees = 182,172 apples

I hope this helps

799 apples were produced

Any spam, nonsense, links, and anything that does not relate to this question will get deleted. Thank you.

Answers

So first you gotta convert 2 2/5 into and improper fraction which gives you 12/5. Which brings you to 12/5 x 5/7, you’re gonna wanna cross cancel the most common factor which is the number 5 and that leaves you to build up the fraction 12/7. Now you wanna convert your improper fraction to a mixed number, and you do that by putting it in long division form otherwise said as 12 divided by 7 which leaves you with 1 and a remainder of 5. 1 5/7 is your answer
If your problem is a fraction I can help… 1 5/7
