Answer:
-3n
a10= -30
Step-by-step explanation:
the distance between -3 and -6 is 3.
if you multiply 3 by the 1st term, it's just 3, so the 3 needs to be a -3.
For a10, you plug in 10 into the equation which is -3n. and that is -30.
1 1/2 * 2 3/4 =
3/2 * 11/4 =
33/8 =
4 1/8 miles in 2 3/4 hrs
Answer: A = X + Y
B = X or Y. A = 12, B = 8, X = 2, Y = 10, A = 12, B = 9.
Step-by-step explanation:
Answer:
A=80
B=31
C=64
Step-by-step explanation:
A, 69, and b will equal 180 since it forms a straight line
A+69+b=180
to solve for A we subtract 53+47 from 180 and get 80
80+69+b=180
to get B we subtract 80+69 from 180 and get 31
to get c we add 85+b and subtract it from 180 getting c=64
Answer:
The length and width of another rectangular field with same perimeter but a larger area is 80 m by 70 m
Step-by-step explanation:
The perimeter of the existing field is
2(l + b)
= 2(90 + 60) = 2(150) = 300 yards
So we want another field having the same perimeter but a larger area
The area we have here is 90 * 60 = 5,400 square yards
If we had 80 by 70
Perimeter will still be 2(70 + 80) = 150
But the area will be 80 * 70 = 5,600 square yards
