Answer:
its 1/10
Step-by-step explanation:
4/10-3/10=1/10
Answer:
c: x=2
Step-by-step explanation:
5x-3= 13-3x
+3 +3
5x=16-3x
+3 +3
8x=16
divide all of it by 8 and thats how you get your answer
Answer:
D
Step-by-step explanation:
Using the Cosine rule to find AC
AC² = BC² + AB² - (2 × BC × AB × cosB )
= 18² + 12² - ( 2 × 18 × 12 × cos75° )
= 324 + 144 - 432cos75°
= 468 - 111.8
= 356.2 ( take the square root of both sides )
AC =
≈ 18.9
-----------------------------------------
Using the Sine rule to find ∠ A
=
( cross- multiply )
18.9 sinA = 18 sin75° ( divide both sides by 18.9 )
sinA =
, then
∠ A =
(
) ≈ 66.9°
Answer:
no
Step-by-step explanation:
Proportional must go through (0,0)
0 = 2(0) +7
0 = 7
This is not true so this is not proportional
200 times. Because 1000 divided of 5 is 200. You could divide it using the algorithm.
