Answer:
4+5+6+1=16 divided by 4 equals 4 i divided it by 4 because there are 4 pairs of numbers so the anser is 4
Step-by-step explanation:
2. Each side of a pentagon is the same size.
4cm x 5 = 20cm or 4cm+4cm+4cm+4cm+4cm = 20cm
3. Each side of a square is the same size.
13yd x 4 = 52yd or 13yd+13yd+13yd+13yd = 52yd
4. Add all sides together.
12m+12m+30m+30m = 84m
5. Again add all sides together.
16yd+16yd+4yd+4yd = 40yd
6. Each side of a square is the same size.
7in x 4 = 28in. or 7in+7in+7in+7in = 28in
7. Add all sides together.
2cm+2cm+3cm+3cm = 10cm
8. Each side of a rhombus is the same size. A rhombus has 4 sides.
23in x 4 = 92in or 23in+23in+23in+23in = 92in
9. A regular octagon has 8 sides and each side is the same size.
9cm x 8 = 72cm
Turn 5% into a decimal which is 0.05, then multiply by 2.95 = 0.1475
round it off, which is 0.15
so $0.15 is the tax and if ur looking for the total price then add $2.95 to $0.15
1. You would add 5 to -14, getting -9, which leaves you with 3x=-9. You would then divide -9 by 3, leaving you with x=-3.
2. First, subtract 22 from 10, getting -12=-2c. Next divide -12 by -2, leaving you with 6=c.
3. Add 17 to 18 to get 35=-5b. Then divide 35 by -5, leaving you with -7=b.
4. Subtract 12 from -12, giving you -24=-8x. Then divide 24 by 8, giving you 3=x.
5. Add .03 to -9, giving you 1.3n= -8.97. Divide-8.97 by 1.3 to get n=-6.9.
6. Subtract 7/9 from 2/9 leaving you with -5/9=-5/11h. Divide and get h=1 and 2/9.
Hope this helped! : )
