A1=12, a2=27, a3=42, etc. The pattern is that you’re always adding 15 after starting with 12. So the general rule is...
an=12+15(n-1)
So then...
a18=12+15(18-1)
a18=12+15(17)
a18=267
From these -Tx+y=S. If -T=Q/R, then y=-Qx/R+S, so Ry=-Qx+RS, Qx+Ry=RS=S.
If R is not equal to 1, or S is non-zero, the equations are inconsistent, so there would be no solutions.
If R=1 there are an infinite number of solutions given by Qx+y=S, or y=S-Qx or y=S+Tx.
If S=0, Qx+Ry=0 or y=-Qx/R or y=Tx.
Answer:
The number rounded to the nearest tenth is 15.1
Step-by-step explanation:
<u>Step 1: Make an equation</u>
When a number is decreased by 27%, the result is 11.
x * (1 - 0.27) = 11
<u>Step 2: Solve inside the parenthesis</u>
x * (1 - 0.27) = 11
x * 0.73 = 11
<u>Step 3: Divide both sides by 0.73</u>
0.73x / 0.73 = 11 / 0.73
x = 15.1
