There are 10 marbles total.
Since there's only one red, the chance of getting a red marble is
Answer:
2x − 9 and x + 6
Step-by-step explanation:
2x² + 3x − 54
Factor using the AC method.
2 × -54 = -108
Factors of -108 that add up to 3 are +12 and -9.
Divide by 2 and reduce: 12/2 = 6/1, -9/2 = -9/2.
Therefore, the factors are x + 6 and 2x − 9.
A. 600 x 50= 30,000
B. 1000 x 60=60000
C. 6000 x 30= 180,000
Hope it's correct :)
Answer:
38°
Step-by-step explanation:
The figure given is a triangle.
Sum of angles in triangle = 180°
So;
∠D + ∠E + ∠F = 180°
( 5x - 2) + (9x + 3) + (11x - 21) = 180
5x -2 + 9x + 3 + 11x -21 = 180
25x -20 = 180
25x = 200
x = 8
Now since ∠D = 5x -2;
∠D = 5(8) - 2 = 38°
Answer: -3
Step-by-step explanation: substitute y and x into the formula y=k/x, and that is 4=k/-12. Then you multiply the -12 over, you get that k=-48. Then you substitute that into the same equation getting y=-48/x, but then you see that y should be 16, so then it would be 16=-48/x. Then, you flip the two fractions to make it more simpler looking like 1/16=x/-48x. Then you multiply the -48 over, getting x=-3.
