If each student needs 7 balloons, that would depend on the number of students in question. This can be answered with simple multiplication.

7 balloons x 1 student = 7 balloons
7 balloons x 2 students = 14 ballons
7 balloons x 3 students = 21 ballons
7 balloons x 4 students = 28 ballons
Etc, etc

When Tom found the difference −17 − (−12), he got −29. Complete the statement that explains what Tom might have done wrong.
ad-work [718]

Answer:

- 5

Step-by-step explanation:

Note that - (- 12) = + 12

Thus

- 17 - (- 12) = - 17 + 12 = - 5

It looks like Tom subtracted 12 from - 17, that is - 17 - 12 = - 29

​ Quadrilateral ABCD ​ is inscribed in this circle.
Anna [14]
A quadrilateral, has 4 sides and its internal angles sum, add up to 360, now... you have 3 angles give.. .but we don't have C

so.. C is the difference of all the three angles from 360 or  \bf \measuredangle C=360-x-(2x+1)-148\implies \measuredangle C=360-x-2x-1-148   whatever that is, now, you'll get some value in x-terms

so.... now once we know what C is

you can if you want, do a search in google for "inscribed quadrilateral conjecture",  I can do a quick proof if you need one

but in short, for a quadrilateral inscribed in a circle, each pair of opposites angles are "supplementary angles", namely they add up to 180°

so.. what the dickens does all that mean?   well D+B=180 and A+C = 180

now. we know what A is, 2x+1
and by now, you'd know what C is from  360-x-2x-1-148

so... add them together then   and

\bf \begin{array}{cccclllll}&#10;A&+&C&=&180\\&#10;\uparrow &&\uparrow \\&#10;(2x+1)&+&(360-x-2x-1-148)&=&180&#10;\end{array}

solve for "x"
