Answer:
6
Step-by-step explanation:
Start with the number 16
16
• Round to the nearest ten
since 6 is greater or equal to 5 round 1 to 2
20
• Divide by the number in 2 pairs
Divide by 2
10
• Add -5
10 + -5 = 5
• Increase by 1
5+1 = 6
Answer:
x=

333
y=

283
Step-by-step explanation:
1 Solve for yy in 13+2x+y+90=18013+2x+y+90=180.
y=-2x+77y=−2x+77
2 Substitute y=-2x+77y=−2x+77 into 4x+1+8x-2y=1804x+1+8x−2y=180.
16x-153=18016x−153=180
3 Solve for xx in 16x-153=18016x−153=180.
x=\frac{333}{16}x=
16
333
4 Substitute x=\frac{333}{16}x=
16
333
into y=-2x+77y=−2x+77.
y=\frac{283}{8}y=
8
283
5 Therefore,
\begin{aligned}&x=\frac{333}{16}\\&y=\frac{283}{8}\end{aligned}
x=
16
333
y=
8

Done
Answer:
11
Step-by-step explanation:
f(12) = 2/3x+3
So, replace x with 12.
2/3(12) + 3
2/3 x 12 = 8
8 + 3 = 11
