Answer:
wait im a little confused sorry but im going to try my best
Step-by-step explanation:
50x2=100. 5×2=10. 500x2=1,000
1,000÷10=100. 100÷10=10. 10,000÷10=1,000
Answer:
9/10
Step-by-step explanation:
If you are truly "struggling," you might want to consider working the problem using your calculator. It will give you a decimal answer: 0.9.
You know this is nine tenths, or 9/10 when written as a fraction.

When adding fractions, you are instructed to use a common denominator. Usually, that instruction is to find the "least" common denominator. In many cases, that simplifies reducing the fraction that will be the answer.
However, <em>any</em> common denominator will do. The easiest one to find is the product of the denominators. Here, that is 2·5 = 10.
The first fraction has a denominator of 2, so to make its denominator 10, you need to multiply it by 5/5.
The second fraction has a denominator of 5, so to make its denominator 10, you need to multiply it by 2/2.
![\dfrac{1}{2}+\dfrac{2}{5}\\\\=\dfrac{1(5)}{2(5)}+\dfrac{2(2)}{5(2)}=\dfrac{5}{10}+\dfrac{4}{10}=\dfrac{5+4}{10}\\\\=\boxed{\dfrac{9}{10}}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%2B%5Cdfrac%7B2%7D%7B5%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1%285%29%7D%7B2%285%29%7D%2B%5Cdfrac%7B2%282%29%7D%7B5%282%29%7D%3D%5Cdfrac%7B5%7D%7B10%7D%2B%5Cdfrac%7B4%7D%7B10%7D%3D%5Cdfrac%7B5%2B4%7D%7B10%7D%5C%5C%5C%5C%3D%5Cboxed%7B%5Cdfrac%7B9%7D%7B10%7D%7D)

Effectively, we have used the formula for the sum of two fractions:
(a/b) +(c/d) = (ad +bc)/(bd)
1/2 + 2/5 = (1·5 +2·2)/(2·5) = 9/10
Okay
We have
slope(m)=-2/5
Point (0,-7)
For this question we use point slope form so
y − y1 = m(x − x1)
y=y coordinate of second point
y1=y coordinate of point one
M=slope
X=x coordinate of second point
x1=x coordinate of point one
By substituting each number to the corresponding variables we get
Y-(-7)=-2/5(x-0)
Y+7=-2/5x
Y=-2/5x-7 equation of required line!
