3x+5=2x-10
-2x -2x
X+5=-10
-5 -5
X=-15
3(-15)+y=5
-45+y=5
+45 +45
y=50
2(-15)-y=10
-30-y=10
+30 +30
-y=40
Divide by -1 on both sides
y=-40
Answer:
1 - sin² θ = 1 - ( 1 - cos² θ) = cos² θ
tan x csc x = (sin x / cos x) * 1 / sin x = cos x
Step-by-step explanation:
1 - sin² θ = 1 - ( 1 - cos² θ) = cos² θ
tan x csc x = (sin x / cos x) * 1 / sin x = cos x
Answer:
A = 48 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
here b = 16 and h = 6 , then
A =
× 16 × 6 = 8 × 6 = 48 ft²
Answer:
3/8 = 12/32 is a proportion
Step-by-step explanation:
2:3 and 9:4 is not a proportion, 10/12 and 20/25 is not a proportion, 4/9 and 17/38 is not a proportion
Answer:
<h2>192 inches ²</h2>
Step-by-step explanation:
P= (l+w)
56 = 2(l+8)
56=2l+8
56-8= 2l
48=2l
Length=24
Area = ?
A = l×w
A=24×8
Area= 192inches²
