Answer:
$0.80
Step-by-step explanation:
$16.40 ÷ 20.5 = 0.80
You can check your work by doing :
20.5 cm of wire × $0.80 = $16.40
D 80
32/40 *100
Precent proportions
32/x = 40/100
Cross multiply
Answer: -1
Step-by-step explanation:
3( x +7 ) =18
8Use distributive property
3x + 21 = 18
Substract 21 from both sides
3x = -3
Divide 3 by both sides
x = -1
Another way to solve:
3( x +7 ) =18
Divide 3 by both sides
x + 7 = 6
Substract 7 by both sides
x = -1
Answer:
X is the hypotenuse and using 60°
Cos theta =adjacent/ hypotenuse
where 5 is your adjacent cos 60° is equals to 5/X
X= 5/Cos 60° = 5/0.5 = 10... B
