Answer:
x = -9
y = 2
Step-by-step explanation:
x + y = -7 then x = -y - 7
-x + 4y = 17
substitute for x:
-(-y - 7) + 4y = 17
reduce:
5y = 10
y = 2
x = -2 - 7
x = -9
check:
-9 + 2 = -7
-7 = -7
-(-9) + 4(2) = 17
17 = 17
Answer:
x = 14
EHF = 15 degree GHF = 75 degree
Step-by-step explanation:
(x+1) + (5x+5) = 90
(x+5x)+ (1+5) = 90
6x + 6 = 90
6x = 90-6
6x = 84
x = 84/6
x = 14
EHF + GHF = 90 degree
EHF = x+1
= 14 + 1 = 15
= 15 degree
GHF = 5x+5
= 14 x 5 (+5) = 70 + 5
= 75 degree
EHF = 15 degree GHF = 75 degree
Out of every 11 liters of Petrolyn, 7 are natural, and 4 are sythetic. So:
792/11=72
72x7=504 liter of natural oil needed
