300 + 0+ 1, 200 + 50+ 6, 800 +70 + 8.
I think it may be 5+3 and carry the one up top to get the sum of 56.
Answer:
75 Arrangements
Step-by-step explanation:
Girl can secure 1st & 3rd, boy can secure 2nd position in : 6 x 5 x 5 = 150 ways ; As :
- 1st position holder can be chosen in 6 ways (among 6 girls)
- 2nd position holder can be chosen in 5 ways (among 5 boys)
- 3rd position holder can be chosen in ( among 5 remaining girls)
The arrangement of first, second & third :
It is same : If Girl G1 gets first rank & Girl G2 gets third rank, is same as ; Girl G1 gets third rank & Girl G2 gets first rank. So, two are considered the same group. Hence, number of arrangements are 150 / 2 = 75 arrangements.
You need to subtract 6 from 24 because it’s the inverse operation of addition which will help you find the unknown value, x.

Answer:
2x -3y = -19
Step-by-step explanation:
Taking the differences between the given points, we have ...
(Δx, Δy) = (4, 9) -(-2, 5) = (6, 4)
The equation of the line can be written ...
Δy·x -Δx·y = Δy·(x1) -Δx·(y1) . . . . . for point (x1, y1) on the line
4x -6y = 4(-2) -6(5) = -38
Dividing by 2 gives the standard form equation ...
2x -3y = -19

<em>Additional comment</em>
The original equation 4x-6y=-38 satisfies the requirements of this problem. However, "standard form" requires the numbers in the equation be mutually prime (in addition to the problem requirements). That is, they must have no common factors. Hence, we must remove the common factor of 2 in order to have true "standard form."
