(180 * 2) * 3 + 200 * 2
360 * 3 + 400
1080 + 400 = 1480 feet
Yes pi, which letter please?7th grade is not an average
This is a formula if you need one. DON'T forget to cross-multiply
3/4 = x/12
Answer:-3
Step-by-step explanation:
Answer:
-2, -6
Step-by-step explanation:
using cramer rule
5 -3
-2 -1
calculatiing the determinant = (5 x-1) - (-3x-2) = -5 -(6) = -5-6=-11
using cramer rule
to calculate x we change the coefficient of x with the answer (8,10)
8 -3
10 -1
we calculate determinant = (8x-1)-(-3x10) = -8-(-30) = -8+30 =22
to calculate x
22/-11= -2
to calculate y we change the coefficient of y with the answer (8,10)
5 8
-2 10
we calculate determinant = (5x10)-(8x-2) = 50 -(-16) = 50 +16=66
to calculate y
66/-11= -6
