Answer:
A
Step-by-step explanation:
Just add both matrices
<span>4−(2x+4)=5
4 - 2x - 4 = 5
-2x = 5
x = -5/2
x = - 2.5</span>
Answer:
a) 14
=14 x 16 ounces
= 224
b) 18.2 x 1 kilogram
= 18.2 x 1000 grams
= 18200
Step-by-step explanation:
Answer:
17.5
Step-by-step explanation:
Given that the variables x and y have a proportional relationship.
i.e. y is directly proportional to x or can be written as
y = mx where m is the constant of proportionality.
When x =2, y =7
Substitute this to get the value of m.
7 =2m or m = 3.5
Thus the relationship between x and y is
y = 3.5x
So when x=5, y = 3.5(5) = 17.5
If you set it up in cross multiplication then you would have (x/100 = 45/54) then cross multiply so then i would look like this (54x/4,500) so from there you would divide 54 from 4,500 i hope this helps in any way oh and it should come up to be 83.3333333 which would be 83% lol
