Answer:
1/10 + 3/5=7/10
Step-by-step explanation:
The Traingle XYZ and ACB are similar triangles. tanX = tanA = 5 over 2 and 5 tenths,
AC = 2 * XY; CB = 2 * YZ
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Triangle XYZ was dilated by a scale factor of 2 to create triangle ACB, hence XYZ and ACB are similar triangles.
Angles Y and C both measure 90 degrees, and angles A and X are congruent. Hence:
tanX = tanA = 5 over 2 and 5 tenths
AC = 2 * XY; CB = 2 * YZ

Answer:
-3/5
Step-by-step explanation:
Find an easy to read point on the intersection of grid lines.
Go up vertically and left horizontally.
up 3 units = rise of 3 units
left 5 units = run of -5 units
slope = rise/run = 3/(-5) = -3/5
Hello!
First you have to find how many marbles there are
5 red
10 blue
3 yellow
7 green
Add these up
5 + 10 + 3 + 7 = 25
To find the probability of not choosing a red marble you put the amount of marbles that are not red over the total amount of marbles
20 non-red marbles
25 marbles in total
So the probability is 20/25
This can be simplified to 4/5
The answer is 4/5
Hope this helps!
