B because 300 is the total. In order to get the total you would need to add 10x and 15y. Both x and y represent the amount of people.
Problem 10
You are correct. You divide 360 over the exterior angle measure to get 360/72 = 5
=========================================================
Problem 11
x = 33 is correct as this angle is an alternate interior angle pair with the 33 degree angle up top
y = 38 is correct since y+33+109 = 180 solves to y = 38. In other words: 38+33+109 = 180
z = 109 is correct. The opposite angles of a parallelogram are congruent
Answer:
(-5, 4)
Step-by-step explanation:
To find the new coordinate, subtract 8 from the x value and add 7 to the y value:
3 - 8 = -5
-5 will be the new x coordinate
-3 + 7 = 4
4 will be the new y coordinate
So, the coordinate K will be (-5, 4) after the translation
Answer:
if x=4 then y=18
Step-by-step explanation:
hope this helps
please mark brainliest ;)
Let the number be x
(9+2x)×2= (-3x)+4
18+4x=-3x+4
4x+3x=4-18
7x=-14
x=-2
