What’s the answer to this ?

109

Step-by-step explanation:

A witch is 15 + 15 + 15 = 45

A wand is 7 + 7 + 7 = 21

A broom is 4 + 4 + 4 = 12

First you do one witch which is 15, times one wand which is 7

So, 15 x 7 = 105

Then 105 + one broom which is 4 equals  109

Step-by-step explanation:

The wand/star is 7+7+7=21

The broom is 4+4+4=12

The witch is holding a wand and a broom

So: (x is the witch)

7+4+x+7+4+x+7+4+x=45

33+3x=45

3x=45-33

3x=12

x=12/3

x=4

So this makes the last one

4+4x7=?

4+28=32

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
