Answer:
Step-by-step explanation:
a right triangle is half of a rectangle and the area of a rectangle is
area of rectangle = length × width
Area of a triangle is one half times the length times the width
area of triangle = 1/2 × length × width
in this case
length is the number of the y units
width is the number of x axis unit
area of triangle = 1/2 × length × width
area of triangle = 1/2 × (y units) × (x units) you need to count and insert
the number of units into the
equation
area of triangle = 1/2 × (??? y units ) × (??? x units ) do the math yourself
and see if you get one of
answers
Answer: 10%
Step-by-step explanation:
even tho 100 is a bigger number the amount of 10% is 10 times bigger than 100%
Answer: 45
Step-by-step explanation:
In 2016, 1 out of every 5 people under the age of 50 used a cell phone to read e-books. This means that 2 out of every 10 people under the age of 50 used a cell phone to read e-books. Also, 3 out of every 15 people under the age of 50 used a cell phone to read e-books.
Therefore, if there were x people under the age of 50 in 2016, then the number that used a cell phone to read e-books would be
1/5 × x = x/5
If there were approximately 225 million people under the age of 50 in 2016, then the number that were likely to have read an e-book on a cell phone is
225/5 = 45 people.
So first do 3(x+1) which is 3x+3 because you have to multiply the outside number by the stuff in side the parentheses. Then you do the 5(x-2)+7 and it should be 5x-10+7 so now your equation should be 3x+3=5x-10+7 now subtract the 3x from the 5x and now your equation should look like this: 3=2x-10+7. Then you add the 10 and the 7 so now your equation should look like this: 3=2x-3 because it's a -10 and a positive 7 it would be -3. So then you have to add the -3( which now becomes positive to the other 3 in front of the = sign. So now your equation should look like this: 6=2x. Now divide by 2 to get x by its self and now your answer should be 3=x or x=3.
A all squares have the sides
