WidthAnswer:
Step-by-step explanation:
The direct answer to your question is: "No".
because in that equation, 'x' is not 120 or130.
Let's find out what 'x' actually is:
<u>3/5 x = 52</u>
Multiply each side by 5 : 3x = 260
Divide each side by 3 : <em> x = 86 and 2/3 </em>
Y=3.5x+4
a) 5=3.5x+4, 3.5x=1, x=1/3.5=2/7
b) y=3.5*10+4=35+4=39
30: r = -32
38: n < -24
54: ?
