Answer:
a. 11x + d
b. 15m + 10n
Step-by-step explanation:
a. 2(4c+5d) + 3(x-3d)
Break the brackets:
2*4c + 2*5d + 3*x - 3*3d
= 8x + 10d + 3x - 9d
Collect like termsL
= 8x + 3x + 10d - 9d
= 11x + 1d
b. 6(3m+n) - 4(m-n)
Break the brackets:
= 6*3m + 6*n - 3*m - 4*(-n)
= 18m + 6n - 3m - (-4n)
= 18m -3m + 6n + 4n
= 15m + 10n
Hope this helped :3
<h3>Answer: Radius</h3>
Let point A be the center of the circle. Point B is somewhere on the circle edge. The distance from A to B is equal to the radius. The radius is half the diameter which spans the whole circle and it goes through the center. The circumference is the curved distance around the whole circle's perimeter.
Answer:
91
Step-by-step explanation:-5, 1, 7, 13
the common diference is : d = ( 13)-(7)=(7)-(1)=(1)-(-5)=6
the firt term is A1 = -5
the n-ieme term is : An = A1 +(n-1)d
An = -5+6(n-1)
An = 6n-11
the 17th term in the arithmetic sequence is : A17 = 6(17)-11 =91

B = no. of buses
v = no. of vans
b + v less than or equal to 8 ( there are only 8 drivers, but don't have to use them all)
51b + 8v greater than or equal to 193 (the number of seats must be at least 193 but there can be spares)
So these are the inequalities to solve. I did start doing a linear programming graph but the second inequality is horrible so I hope you don't need to actually solve them.
