Eliminate x's by adding te 2 equations
add them
-2x+15y=24
<u>2x+9y=24 +</u>
0x+24y=48
24y=48
divide both sides by 24
y=2
sub back
2x+9y=24
2x+9(2)=24
2x+18=24
minus 18 both sides
2x=6
divide 2
x=3
x=3
y=2
(x,y)
(3,2)
Answer:
i think its -4 and -2
Step-by-step explanation:
You can find the prime factorization of 360 by dividing it by 2. Then you get 2 * 180. 180 can be simplified to 2 * 90. 90 can be simplified to 2 * 45. 45 can simplified to 3 * 15. 15 can be simplified to 3 * 5.
The prime factorization of 360 is 2^3 * 3^2 * 5.
You can check that answer. 2^3 = 8 → 3^2 = 9 → 8 * 9 * 5 = 360
Answer:
The answer is 84.08
Step-by-step explanation:
1) line up the decimal points
2) add it up like any addition problem
3) Place the decimal point right under the placement of the decimal point of the problem
2x + 39 = 77 is the equation trnaslated, thne you subtract 39 from both sides to get 2x = 38 then divide both sides by 2 to get x = 19. the number is 19
