Answer:

30

Step-by-step explanation:

We'll set up an equation to solve this, saying Kamryn is 'x'

x = -40 (lost points in dance category) + 70 (gained points in tumbling)

The equation can be set up like this:

x = -40 + 70

70 - 40 = 30, so x = 30

Your answer is 30.

Bas_tet [7]

Answer:

           yes    no     total

girls     58     32     90

boys    52     40     92

total     110    72     182

if 182 freshmen were surveyed and 110 said yes, then 182 - 110 = 72 said no

if 40 boys said no, then 72 - 40 = 32 girls said no

if 90 girls were surveyed, then 182 - 90 = 92 boys were surveyed

if 40 boys said no, then 92 - 40 = 52 said yes

if 32 girls said no, then 90 - 32 = 58 said yes
