We assume that equilateral triangle is composed of 2 right triangles
as length of side is 12 base length became half as we have 2 triangles hyp remain same i.e 12 and we can find perpendicular using <span>pythagorean theorem</span>
Answer: y = -10
Step-by-step explanation:
y = 2(-3) - 4
-6 - 4 = -10
y = -10
Answer:
11/2 + 4/9
= (11×9 + 4×2) / 18
= (99 + 8) / 18
= 107/18
= 5 17/18

Answer:
b = 5
Step-by-step explanation:
4 ( 3b + 2 ) - 5b = 43 Given
( 4 • 3b + 4 • 2 ) - 5b = 43 Distributive Property
12b + 8 - 5b = 43
12b - 5b + 8 = 43 Combine like terms
7b + 8 = 43
7b + 8 - 8 = 43 - 8 Subtraction Property of Equality
7b = 35
7b / 7 = 35 / 7 Division Property of Equality
b = 5
Answer:
Step-by-step explanation:
9x+
=x-13
9x*3+1/3=x-13
27x+1/3=x-13
27x+1=3(x-13)
27x+1=3x-39
27x-3x=-39-1
24x=-40
x=-5/3
x=-5/3
