Answer:

Step-by-step explanation:

multiply numerators with numerators and denominators with denominators

1) 7/12 x 8/1 = (7 x 8) / (12 x 1) = 56/12 simplify 56/12

= 56/12 = 28 / 6 = 14 / 3 = 4 and 2/3 = 4 and 8/12

2) 9 seeds picks out 3/4 of the seeds

9 x 3/4 = 9/1 x 3/4 = 9x3 / 1x4 = 27/4 = 6 and 3/4

I can't read the other ones but jus follow the examples above

The drama club at Math Academy High School sold tickets to their end of the year play. On Monday they sold 80 tickets for a tota

riadik2000 [5.3K]

Answer: OPTION A

Step-by-step explanation:

Let be "a" the number of adults tickets they sold and "s" the number student of tickets they sold.

With the information given in the exercise you can set up the following System of equations:

$\left \{ {{a+s=80} \atop {6a+4.5s=426}} \right.$

Use the Elimination method to solve the system of equations:

1. Multiply the first equation by -6.

2. Add the equations.

3. Solve for "s" in order to find its value.

Then:

$\left \{ {{-6a+-6s=-480} \atop {6a+4.5s=426}} \right.\\............................\\-1.5s=-54\\\\s=36$

4. Finally, substitute the value of "s" into the first equation and solve for "a":

$a+36=80\\\\a=80-36\\\\a=44$

A line segment has end points of ( 4,-4) and ( 0-5) what are the coordinates of the midpoint of this line segment?

Leni [432]

Use the Midpoint formula

Under a radical it would be

√ ( x↓2 - x↓1 ) ² + ( y↓2 - y↓1 ) ²

The down arrow is subscript -

So use the numbers from the two coordinates to plug in.

If you have any question comment :)

Answer:

C. 65

Step-by-step explanation:

Compare to the standard form ...

ax² +bx +c

to find the values of a, b, c. They are ...

a=2, b=3, c=-7

The discriminant is ...

d = b² -4ac

d = (3)² -4(2)(-7) = 9 +56

d = 65 . . . . . . matches choice C
