Answer:

Step-by-step explanation:


This is because we subtract 456 from each side.

We then divide the whole equation by <em>x</em> .

Adding 50 to both sides gives us <em>x</em> by itself, hope this helps :D
Answer:
Width =
ft
Step-by-step explanation:
The tank holds 150 gallons of water.
7.5 gallons holds 1 ft³ of water.
So 150 gallons will hold;
× 1 ft³ = 20 ft³
The volume of the tank = Length(l) × Width(w) × Height(h) = 20 ft³
i.e 5 ft × w × 3 ft = 20 ft³
15w ft² = 20 ft³
w =
=
ft
Answer:
89.04% of the data points will fall in the given range of z = − 1.6 and z = 1.6
Step-by-step explanation:
We are given a normally distributed data.
We have to find the percentage of data that lies within the range z = − 1.6 and z= 1.6
Formula:

89.04% of the data points will fall in the given range of z = − 1.6 and z= 1.6
First, identify the terms.
23
+6c
+8d
-7d
-6
Now combine like terms. Like terms are terms with the same variable (i.e. 1x and 3x)
23 and -6
6c
8d and -7d
Now combine!
23 - 6 = 17
6c = 6c
8d - 7d = 1d
So the answer is 17 + 6c + 1d
