Idon't get it? show me what formula of math you used to get the answer .

So, if there are 3 bees and that is equivalent to 15. Then you would divide 15 by 3. (15÷3=5) Each bee=5

Because we know that 3 bees equal 5, we can figure out how much eat dragonfly is worth. If 3 dragonflies + 3 bees (15) = 27 then you would subtract 15 from 27 (27-15=12) So, 3 dragonflies=12

To find out how much each dragonfly is worth you would divide 12÷3=4 because 3 dragonflies=12 then each dragonfly is equal to 4.

Bee=5

Dragonfly=4

You can now solve the remaining two questions using the values above.

Dragonfly(4)+Bee(5)=9

2 Dragonflies=8 because each dragonfly is 4

2 Bees=10 because each bee is 5

2 Dragonflies(8)+2 Bees(10)=18

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
