Collecting like terms is to simplify terms in expressions in which the variables are the same.

Rearranging is to change the position for example changing the place of the = sign to change the meaning of the equation.

19. The heights, in inches, of players on a basketball team are:

Rom4ik [11]

Hello!

Let's find the mean of each team. Let's add up all of the heights and divide by number of players.

57+63+68+72+50+63+65+69+73+71+60=711

711/11≈64.64

Now we do the same with the soccer team.

49+53+52+52+57+61+55+61+59+61+50+50+51+62+50+57=880

880/16=55

Now we subtract.

64.64-55≈10

Therefore, our answer is D) 10 inches

I hope this helps!

Bianca and Meredith are sisters. Meredith's height is 23 of Bianca's height plus 32 inches. Meredith is 60 inches tall. M Write

Anna [14]

Answer:

The height of Bianca = 42 inches

Step-by-step explanation:

The given height of Meredith = 60 inches

Let us assume the height of Bianca = x inches

Now, given Meredith's height = 2/3 of Bianca's Height + 32 inches

$\implies 60 = \frac{2}{3 } \times x + 32$

or, $\frac{2}{3 } \times x = 60 -32 = 28\\\implies x = 28 \times \frac{3}{2 } = 42$

or, x = 42

Hence the given height of Bianca = x = 42 inches
