Solve for v by simplifying both sides of the equation, then isolating the variable.
v = -1
Answer:
$3.60.
Step-by-step explanation:
4.5 = x + 20% of x
4.5 = x + 0.2x
1.2x = 4.5
x = 3.75
Answer:
19,200 cm^2.
Step-by-step explanation:
The area = 1.2 * 1.6 = 1.92 m^2.
There are 100 cm to 1 meter, so 1 square meter = 100^2 = 10,000 cm^2.
Therefore 1.92 m^2 = 10,000 * 1.92 = 19,200 cm^2.
Answer:
The slope is 2
Step-by-step explanation:
Pick two points and plug into this equation: y2-y1/x2-x1
(-3,2) and (-1,6)
2-6/-3-(-1)=-4/-2= 2
