I know that because I multipled 10x9x17 and then dived it by 3
Answer:
$16.25
Step-by-step explanation:
9.75/3 = 3.25
So therefore 1 bag costs $3.25.
$3.25 × 5 = $16.25
So 20=80%'
% means out of 100 so
80%=80/100 so
20=80/100
we try to get to 100/100 so
20=80/100
5=20/100
5 times 20=100 so
25=100/100
there were 25 questions total
with "k" being the "constant of variation"
so. hmm in this case is "w" inversely varying to the square of the distance or d²
thus
solve for "k", to see what the constant of variation is
and plug it back in
now.. .to find her weight when she's 144miles above the surface, well
that's just
and since you already know what "k" is, just divide and simplify away, to get "w"
Answer:
x = 7
Step-by-step explanation:
I reversed it for easy viewing:
(x+7)/3x = 2/3
<=> (x + 7).3 = 2.(3x)
<=> 3x + 21 = 6x
<=> 21 = 6x - 3x
<=> 3x = 21
<=> x = 7
