30-(11+(18-(48/8×2))+7)+15
= 30-(11+(18-12)+7)+15
= 30-(11+6+7)+15
= 30-24+15
= 21
Answer:
S=98
Step-by-step explanation:
If S2 is 196 we can divide that by two and get our answer: s=98
in 1st figure
2:1=(x+2):2
2/1=(x+2)/2
4=x+2
x=2.
Similarly in the 2nd figure
8:5=(8+3):(5+x)
8/5 = 11/ (5+x)
8(5+x) =55
40+8x=55
8x=15
x=15/8
x=1.875
<h3>Of the four listed equations, B is the only equation that is not linear.</h3>
A linear equation is any equation that results in a straight line, as each value is a fixed number from the previous.
In a non-linear equation, a variable is being raised to a power, which results in a curved line.
