Answer:
D and yes
Step-by-step explanation:
+ 1 = -3 If we multiply both sides of the equation by 4 will will get the second equation
(4) + (4) 1 = (4) -3
x + 4 = -12 We solve this for x by subtracting 4 from both sides.
x = -16
Plug -7 into both equations and you will see that it is a solution
+ 1 = -3
+ 1 = -3
-4 + 1 = -3
-3 = -3
x + 4 = =12
-16 + 4 = -12
-12 - -12
Answer:
8.5 inches
Step-by-step explanation:
First let's find the time t when the depth of the snow is 7 inches.
To do this, we just need to use the value of D = 7 then find the value of t:
We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:
The depth of snow one hour from now will be 8.5 inches.
Answer:
Step-by-step explanation:
Expand with the distributive rule:
Add 4/3 to both sides:
Subtract 4x from both sides
