We know that we're starting from a certain number m and, after subtracting 23, we're left with -50.
So, you can invent any word problem involving some initial amount, a subtraction of 23, and a result of -50. For example:
"Mary spent $23, and her bank account reads $-50. How much money did Mary have in the first place?".
or
"After the temperature dropped 23 degrees, it was -50 degrees outside. What was the temperature before the drop?"
Answer:
each pair was 1$
Step-by-step explanation:
i don know if the is the uniform way but this is how it was in my head.
if we have 20 apples for 10 dollars then each apple must cost 50c ( 10$ divided by 20)
so if we said how many were each pair you would add two together to to get your answer
Answer:
900 g
Step-by-step explanation:
let e be extension and w be weight
given e varies directly as w then the equation relating them is
e = kw ← k is the constant of variation
to find k use the condition w = 150 , e = 2.9 , then
2.9 = 150k ( divide both sides by 150 )
= k , that is
k =
e = w ← equation of variation
when e = 17.4 , then
17.4 = w ( multiply both sides by 1500 )
26100 = 29w ( divide both sides by 29 )
900 = w
F(x) typically stands for y. So, f(-2) would mean that y=-2, and -2 would equal 2*2, which is false.
