Answer:
y=-10
Step-by-step explanation:
-3(y+5)=15
y+5=15/-3
y+5=-5
y=-5-5
y=-10
I = prt
450 = 3000 x r x 3
450 = 9000r
450/9000 = 9000r/9000
r = 0.05
453.592 grams is in one pound.
Answer:
The two numbers are <em>32</em> and <em>60</em>.
Step-by-step explanation:
We can create two simultaneous equations to solve this problem using the information given in the question.
Let number 1 = x
Let number 1 = y
x = y - 28 -> ( 1 )
x + y = 92 -> ( 2 )
We can solve simultaneous equations using substitution or elimination. For this question, we will use substitution as it is the easier option.
Substitute ( 1 ) into ( 2 ):
x + y = 92 -> ( 2 )
( y - 28 ) + y = 92
2y - 28 = 92
2y = 120
y = 120 / 2
y = 60 -> ( 3 )
Substitute ( 3 ) into ( 1 ):
x = y - 28 -> ( 1 )
x = ( 60 ) - 28
x = 32
Therefore:
x = 32 , y = 60
The quotient rule is as follows
((l)•(h’) - (l’)•(h))/(l)^2
With l representing “low” or “bottom equation” and h representing “high” or “top equation”
Let’s plug in v^k and v^h in this case
((v^h)(v^k)’ - (v^h)’(v^k))/(v^h)^2
