Answer:
Step-by-step explanation:
Given
Required
Solve using distributive property
can be rewritten as
So:
Factorize:
Now, we can apply distributive property on the expression;
Hence, the above is an equivalent expression.
Solving further, we have
Set a proportion
1/2.54=x/508..___Cross multiply.
2.54x=508
2.54/2.54x=508/2.54
x=200
Therefore there are 200 inches in 508 centimeters
1 km = 1,000 m
43 km = 43,000 m
4,300 m < 43,000 m
so 4,300 m < 43 km
Y = kx
15 = -3k
k = -5
so if x = 4
y = kx
y = (-5) (4) = - 20
answer
<span>y = -20 when the x = 4.</span>
