Answer:
Step-by-step explanation:
Let
w ----> the amount of weight lost in pounds
we know that
The amount of weight Bernard lost plus the weight of this week must be equal to the weight of the last week
so
The linear equation that represent this situation is
solve for w
subtract 2,312 both sides
Answer:
x or 1x.
Step-by-step explanation:
The rate of change is slope.
Slope=m
y=mx+b
y=<u>x</u>+5
x is the same thing as 1x. So...
Answer:
y = 8 + 4x / 2
Step-by-step explanation:
w - width
3w - 1 - length
54 in - perimeter
w + w + (3w - 1) + (3w - 1) = 8w - 2 - perimeter
The equation:
8w - 2 = 54 <em>add 2 to both sides</em>
8w = 56 <em>divide both sides by 8</em>
w = 7
3w - 1 = 3(7) - 1 = 21 - 1 = 20
<h3>Answer: The length = 20 in.</h3>
Answer:
9.8 cm
Step-by-step explanation:
Volume of a sphere, V = 4/3 πr³
V = 500cm³
π = 3.14
500 = 4/3 * 3.14 * r³
500 * 3 = 4 * 3.14 * r³
1500 = 12.56r³
r³ = 1500 / 12.56
r³ = 119.42675
r = (119.42675)^1/3
r = 4.9245574
Diameter = 2r
Diameter = 2 * 4.9245574
Diameter = 9.849
= 9.8cm
