Given:
4x + 7 = 23
Let's solve for x.
First Step:
Subtract 7 from both sides
4x + 7 - 7 = 23 - 7
4x = 16
Next Step:
DIvide both sides by 4

ANSWER:
x = 4
1 1/2 - 1/4
You have to have a common denominator which is 4 in this istance.
That makes it 1 2/4 - 1/4. That equals 1 3/4.
Hope that this helped! :)
Answer: 42 feet
Step-by-step explanation:
P-area of field
P=2100sqf
a-length of field

P=a*b
2100sqf=50*b
b=2100/50
b=42 feet
Answer:
1
Step-by-step explanation:
Slope is given by
m = (y2 -y1)/(x2-x1)
= ( -2 - -8)/( 2 - -4)
=( -2+8) / (2+4)
=6/6
=1
