Bob has 15 more marbles than Joe Andy has 25 more marbles than the number of marbles bob and Joe have together the three boys have 535 marbles altogether how many marbles does bob have?

The value of no. of marbles does bob has = 135

Step-by-step explanation:

Let no. of marbles Bob has = x

no. of marbles Andy has = y

no. of marbles Joe has = z

From the given data in the question,

x = 15 + z 1    

y = 25 + x + z 2

x + y + z = 535 3

Put the value of x from equation 1 to equation 2 we get ,

y = 25 + 15 + 2 z = 40 + 2 z 4

Put the value of x and y from equation (1) and (4) to equation (3) we get

⇒ 15 + z + 40 + 2 z + z = 535

⇒ 55 + 4 z = 535

⇒ 4 z = 480

⇒ z = 120 5

 Put this value of z in equation 4 we get

⇒ y = 40 + 2 × 120

⇒ y = 280   6

 Put this value of y and z in equation 3  we get

    x =  535 - 280 - 120

    x = 135 7

    Thus the value of no. of marbles does bob has = x = 135

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
