Answer:
14%
Step-by-step explanation:
<em><u>49 parts of 350 parts</u></em> do not need specifications...
= 49/350
So, 49/350 = x/100
= <u>49(100) = 350x</u>
= 4900 = 350x
= 4900/350 = x
x = 14%
Answer:
x=-8
Step-by-step explanation:
I solved for x and got this :)
Hope this helps :D
<u>Direct Variation:</u> 

when y = 7: 
14 = 15x

<u>Inverse variation:</u> y*x = k
15 * 2 = k
30 = k
when y = 7: 7 * x = 30

Answer:
Step-by-step explanation:
y + 3 = 7(x - 1)
y + 3 = 7x - 7
y = 7x - 10
