Answer:
x = 16
Step-by-step explanation:
3x - 10 = 2(x+3)
<em>First step is solve this:</em>
<em>2(x+3) = 2*x + 2*3 = 2x + 6</em>
then:
3x - 10 = 2x + 6
3x - 2x = 6 + 10
x = 16
Check:
3*16 - 10 = 2(16+3)
48 - 10 = 2*19 = 38
Answer:
10% increase
Step-by-step explanation:
22-20/20 (increase/original)
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k) = (5, 7) and r = 2 ⇒ r² = 4, hence
(x - 5)² + (y - 7)² = 4 → A
To get r you have to divide:
-8r=64
----------
-8
You would divide by -8 because you are trying to get r by itself and make sure when you divide one side divide the other one:
-8r=64
---------- r= -8
-8
You would get -8 when you divide 64/-8 because a negative and a negative gives you a positive hope this helps a bunch :)))))
Let the weight of the heaviet package = X
Weight of the smallest package = X/2+(1/3*X/2)
= X/2+X/6
= 2X/3
Then
X+2X/3 = 100
(3X+2X)/3 = 100
5X/3 = 100
X = 300/5
= 60
Then the weight of the smallest package = 2X/3
= 2*60/3
= 40
So the weight of the smallest package is 40 Kg.
