.6 / 3.66 , just divide it
First, simplify this system:
<span>2x = -10y + 6 and x + 5y = 3
by dividing the first equation by 2. Result: </span><span>x = -5y + 3
Subbing this into the 2nd equation, -5y + 3 + 5y = 3
This equation is always true, so this system has infinitely many sol'ns.</span>
1 full cup = 4 fourth cups, 3*4=12 12+1=13

Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
15x + 3 + 3x - 1 + 52 = 180
15x + 3x + 3 - 1 + 52= 180
Combine like terms.
18x + 54 = 180
To find the vlaue of x, we have to islolate x
<u>Step1:</u> Subtract 54 from both sides
18x = 180 - 54
18x = 126
<u>Step2:</u> Divide both sides by 18
x = 126/18
x = 7
