3) Exact
4) Exact
5) Approximation
Step-by-step explanation:
Y * 10 = z
y = dollars
z = dimes
4 dollars = 4y
Replace y with 4:
4* 10 = 40.
The total amount of dimes in 4 dollars is 40 dimes.
Hope this helped☺☺
y = x + 2
y = -3x
Do y = -3x in y = x + 2
y = x + 2
-3x = x + 2
-3x - x = 2
-4x = 2
x = -2/4
x = -1/2
Now put x = -1/2 in y = -3x
y = -3x
y = -3.(-1/2)
y = 3/2
C) 22
86/4 = 21.5
*5 Or more, raise the score*
(rounds to 22)
you should have 2 lightbulbs left over but you would be 2 lightbulbs short if you were to get 21 packages as opposed to 22
