Answer:
Step-by-step explanation:
A + G + M = 740
A = G - 20
A = M - 120
Therefore,
G = A + 20
M = A + 120
Plug it in...
A + (A + 20) + (A + 120) = 740
Combine like terms
3A + 140 = 740
- 140 -140
3A = 600
/3 /3
A = 200
Double check
A = 200, G = 220, M = 320
200 + 220 + 320 = 740

Answer:
9
Step-by-step explanation:
All triangles (3 sided polygons) have angles added up to 180, so we can do the following:
(7x-1) + (7x+8) + (5x+2) = 180° <em>- equation</em>
7x-1 + 7x+8 + 5x+2 = 180° <em>- "distribute"</em>
19x - 1 + 8 + 2 = 180°<em> - combine the x terms</em>
19x + 9 = 180° <em>- combine the integer terms</em>
19x = 171 <em>- subtract 9 form both sides</em>
x = 9 <em>- divide both sides by 19</em>
Answer:
Step-by-step explanation:
6)Let the number be x
Product of a number and -4 = x * -4 = -4x
Product of a number and -4 increase by 3 : -4x + 3
-4x +3 = 9
Subtract 3 from both sides
-4x + 3 - 3 = 9 - 3
-4x = 6
Divide both sides by (-4)
-4x/-4 = 6/-4
x = -3/2
x = -1 1/2
7)Let the number be x
Add 9 to both sides
Multiply both sides with 6
x = 120
Hmmm Interesting: 189.5+129.5+99.5+53
I got 471.5 Dollars....
Because Look If they buy 10 tickets each category it be 18.95 times 10= 189.5
then 12.95 times= 129.5 , Then 9.95 times= 99.5.... Also if they plan to get 30 combos it be also 5.50 times 30,,, You add the answers and it will give you 471.5 dollars. You can try doing it in a caculator (:
