How does x fit in t this equation?
Answer:
l = 44 ft
w = 20 ft
Step-by-step explanation:
Perimeter is
P = 2 ( l+w)
The width is
w = l -24
We know the perimeter is 128 and substituting into the equation for perimeter
128 = 2 ( l + l-24)
128 = 2 ( 2l -24)
Divide by 2
128/2 = 2/2 ( 2l-24)
64 = 2l - 24
Add 24 t o each sdie
64+24 = 2l
88 = 2l
Divide by 2
44 =l
The length is 44
Now find w
w = l - 24
w = 44-24
w = 20
Given equations are y = 7x − 8 and y = 5x − 2
We can solve them easily using substion.
Plug y = 7x − 8 into y = 5x − 2
7x − 8 = 5x − 2
or 7x − 5x =8 − 2
or 2x = 6
or 2x/2 = 6/2
or x=3
Now plug x=3 into any of given equations say y = 5x − 2
y = 5(3) − 2=15-2=13
Hence (3,13) is the final answer.
Answer:
t = -6.25
Step-by-step explanation:
3/4 (184+t) =237
multiply by 3/4
184 + t = 177.75
subtract 184
t = -6.25
