X=7
A straight line equals 180 degrees so you will need to sue this equation:
(6x+8)+(4x+2)=180
Add like terms; 10x+10=180
And simplify to get answer
X=17
To check the answer just plug in 17 for all the x variables and it should equal 180 in total
.25 x 4,200 = 1,050.
4,200 - 1,050 = 3,150
The answer is $3,150
Let the number of Blue casset be b and that of green be g.
Thus the total number of cassets will be:
b+g=16
hence
g=16-b.......i
The total amount was:
45b+55g=830..ii
plugging i in ii we get:
45b+55(16-b)=830
45b+880-55b=830
simplifying
45b-55b=830-880
-10b=-50
thus
b=5
hence
g=16-5=11
number of blue cassets was 5 and that of green was 11
.75 = 3/4
Hope that helps :)
5 divided by 482 is 96 R2 because 5 can go into 48 9 times so 48 - 45 equal 3 than bring down the 2 5 can go into 32 6 times 32 - 30 equal 2
