Answer:
first box 1.5, second box -1.5 don't forget the negative for the second box
Step-by-step explanation:
In order to solve this problem, we transform the statements into
algebraic expressions. First, we assign the variables.
Let:
x = Gina’s number
y = Sara’s number
For the first equation, we show that Gina’s number is greater
than Sara’s number by 2. For the second equation, we show that the sum of both
numbers is 68.
<span>(1)
</span>x – y = 2
<span>(2)
</span>x + y = 68
<span>We
add the two expressions, which result in the expression: 2x = 70. Then we
divide 70 by 2 to get the value of x. We then have x = 35. Using the second
equation, we solve for y = 68-35. This gives y = 33. To summarize, Gina’s
number is 35 while Sara’s number is 33.</span>
Answer:
yes no total
girls 58 32 90
boys 52 40 92
total 110 72 182
Step-by-step explanation:
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
