Answer:
Choice C
Step-by-step explanation:
f: initial value of 200 decreasing at a rate of 4%
g: initial value of 40 increasing at a rate of 8%
f is decreasing so it must go down starting at 200
That eliminates a and d
g is increasing and starts at 40 That eliminates a
We must look at b and c
g is increasing faster than f is decreasing
Choice C
I: 2x+y=5
II:3x+2y=4
start by eliminating y
-2*I: -4x-2y=-10
II: 3x+2y=4
add both equations together
-2*I+II: -4x-2y+3x+2y=-10+4
-1x=-6
x=6
insert x=6 into I:
2*6+y=5
y=5-12
y=-7
so the solution is x=6, y=-7
The distributive property is 15+45 = (10 + 40) + (5+5) = 50 + 10 = 60
Hope this helps you.
Answer:
1. 1,016 sq. m.
2. 119 sq. m.
Step-by-step explanation:
1.
14 x 18 = 252
18 x 8 = 144
14 x 8 = 112
2 ( 252 ) + 2 ( 144 ) + 2 ( 112 )
504 + 288 + 224 = 1,016 sq m
2.
4 (7 x 5 divided by 2) + (7 x 7) =
7 x 5= 35 divided by 2 = 17.5 x 4 = 70 + 49 = 119 sq. m.
I hope this helps
