reduce the expression and if possible do that by cancelling the common factors :)
Where's the question 12 a =
Answer:
x=0
y=-21/7
Step-by-step explanation:
Let the two unknown be x and y
x+y=-7...(1)
x-y=14...(2)
From (1) make x the subject of formula
x=-7-y...(3)
Substitute (3) into (2)
-7-y-y=14
-7-2y=14
Add 7 to both sides
-2y=21
Add both sides by-2
y=-21/2
Substitute the value of y into (3)
x=-7-(-21/2)
x=-7+21/3
Lcm
x=-21+21/3
x=0/3
x=0
<span>A is the correct answer. To find 10% of 50, divide it by 10. This gives you 5. If 5 is 10%, then 20 is 40%, because 20 is 4 x 5 and 40 is 4 x 10. </span>
Answer:
301.6, 188.5
Step-by-step explanation:
to find the volume of the cone is πr
so π x 6
=301.59 or 301.6
now to find the curved surface area of the cone is πrl
so π x 6 x 10
=188.49 or 188.5
