3 (k-12) = k-30
3k - 36 = k - 30
3k - k = -30 + 36
2k = 6
k = 3
First, you can convert yards to feet, to make it easier to simplify feet to inches. There are 3ft in a yard, so you can say that there are 3ft*7+2ft. 3*7 is 21, and adding 2 to that you will have 23ft. from here you can convert that directly to inches. If there are 12 inches in a foot, you will multiply 12 by 23. Your final answer will be 276in.
Answer:
44+50 =94 in²
Step-by-step explanation:
Trapezoid
A= 1/2h(b1+b2)
A= 1/2*4(7+15)
A=1/2*4(22)
A=44
Rectangle
A=l*w
A=5*10
A=50
44+50 =94 in²
Answer:
67.307
Step-by-step explanation:
