Charlotte has a large container of only red beads. Harry has a large container of only blue beads. Charlotte and Harry swap 30 beads. This means that Charlotte gets 30 of Harry's blue beads in her container and Harry gets 30 of Charlotte's red beads in his container. Charlotte now randomly picks 70 beads from her container and notices that 7 are blue. Harry now randomly picks 60 beads from his container and notices that 45 are blue. If all the beads were placed in one container, work out an estimate for the ratio of red to blue beads. Simplify your answer fully.

i believe the answer is the polygon, heptagon.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
