Answer:
1.075 or 43/40
Step-by-step explanation:
Length(l)= 4+ w
Width(w)=w
Area(A)= 21m^2
so keep in mind Area= Length × width
A= l×w
21=(4+w)(w)
21= 4w+ 2w
21=6w
w=3.5
The width is 3.5m
so the answer is about 4m
Answer:
25 so C
Step-by-step explanation:
Answer:
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7 Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y = -11.
15h + 80 = 140
If you wanted to solve how many hours he worked:
15h + 80 = 140
15h = 60
h = 4.
