Part (a)
<h3>Answer:
2(2.4+w) = 14.2</h3>
--------------
Explanation:
L = 2.4 = length
W = unknown width
The perimeter of any rectangle is P = 2(L+W)
We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2
========================================================
Part (b)
<h3>Answer:
w = 4.7</h3>
--------------
Explanation:
We'll solve the equation we set up in part (a)
2(2.4+w) = 14.2
2(2.4)+2(w) = 14.2
4.8+2w = 14.2
2w = 14.2-4.8
2w = 9.4
w = 9.4/2
w = 4.7
The width must be 4.7 cm.
I think the answer is 9
It's a smaller version of the other figure.
21/3=7
27/3=9
Answer: y = (3/2)x
m = 3/2 is the slope
(x1,y1) = (0,0) is the point we want the line to go through, aka the origin
Use point slope form, plug in the given values, and convert to slope intercept form
y - y1 = m(x - x1) .... point slope form
y - 0 = (3/2)*(x - 0) .... substitution
y = (3/2)x .... final answer in slope intercept form
2.74 liters since 1000mL is a liter.
Answer:
So, equation using the given information
:
5 is subtracted from a number the result is the same as the number tripled will be: x-5=3x
Step-by-step explanation:
We need to make an equation of: 5 is subtracted from a number the result is the same as the number tripled.
Let, the number be x
5 is subtracted from a number will be: x-5
The number tripled will be: 3*x
The required equation will be:
x-5=3x
So, equation using the given information
:
5 is subtracted from a number the result is the same as the number tripled will be: x-5=3x
