Answer:

match bases

remeber if a^b=a^c where a=a then b=c

remember

(x^m)^n=x^(mn)

1/(x^m)=x^-m

base of 3

(1/3)^x=(3^-1)^x=3^(-x)

27^(x+2)=(3^3)^(x+2)=3^(3x+6)

3^(-x)=3^(3x+6)

-x=3x+6

0=4x+6

-6=4x

-3/2=x

Answer and please show work!
snow_lady [41]

Answer:

5

Step-by-step explanation:

If we consider half the first purchase, it is

2 used + 1 new = $42

And the second purchase is

6 used + 1 new = $78

Subtracting the first of these equations from the second, we get ...

4 used = $(78 -42) = $36

used = $9 . . . . . . . . . . . . . . divide by 4

Then we can find the price of a new game from ...

new = $42 - 2 used = $42 -2·9 = $24

___

The number of used games Janet can purchase on her budget is ...

($120 -3·$24)/$9 = $48/$9 = 5 1/3 ≈ 5

Janet can purchase 5 used and 3 new video games for $120. (and have $3 left)

BrainiestI WILL GIVE BRAINLIEST look at the right angled triangle abc
marissa [1.9K]

Answer:

x = 90°

y = 40°

z = 40°

Explanation (Concepts) :

A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.

Workouts:

z + 90° + 50° = 180°

z = 180° - 90° - 50°

z = 40°

=================

x + 90° = 180°

x = 180° - 90°

x = 90°

==================

50° + 90° + y = 180°

y = 180° - 90° - 50°

y = 40°
