Answer:
The value of x is 200 in the equation 1/5x - 2/3y = 30, when y = 15
Step-by-step explanation:
<u>Given</u>
equation: x - 2/3y = 30
when y = 15
<em>Plug in y:</em>
1/5x - 2/3(15) = 30
1/5x - 10 = 30
<em>add</em> 10 to both sides,
1/5x - 10 + 10 = 30 + 10
1/5x = 40
<em>multiply</em> both sides by 5
1/5x * 5= 40 * 5
x = 200
Answer:7
Step-by-step explanation:
all you have to do is subtract 20-13
Answer = p=12-4 -12=17=18+19
p-q
p=12
Answer:
q = - 
p
Step-by-step explanation:
less than p = 
p
Thus
p + q = p ( multiply through by 3 to clear the fraction )
3p + 3q = 2p ( subtract 3p from both sides )
3q = - p ( divide both sides by 3 )
q = - p
