30. are of triangle= 1/2 base x height, just subtract that from the whole rectangle (bxh)
it would look like this:
rectangle: 12x4= 48
triangle: 9x4=36/2=18
48-18=30
30!!!!
Answer:
multiplying equation 2 by 2 and adding eq 1
3x-2y = 17
+4x+2y = 60 3
=
7x = 77
x = 77/7 = 11
then
y = (60-4x)/2 {from equation 3}
y = 60-44/2 = 16/2 = 8
then
<em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>1</u></em><em><u>1</u></em>
<em><u>y</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>8</u></em>
<em><u>hope</u></em><em><u> </u></em><em><u>it</u></em><em><u> </u></em><em><u>helps</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em><em><u> </u></em>

Answer:
There are 14 board games
Step-by-step explanation:
Firs of all I defined two variables
V= number of videogames
B= number of board games
Then I translate the information into math equations:
V=6B-28 represents the number of video games is 28 less than 6 times the number of board games.
represents the games are 80% video games. The equation is the number of video games divided for the total number of games
The two equation form a lineal equations system. It is rewritten below
V-6B=-28
V-4B=0
The solution for this equations system is
V=56
B=14
