Upon formation of an equation from a given pattern, we know how the variables in the patter are related. Using the equation, we can find the value of one of the missing variables if the rest are known and also predict the values of the pattern at given conditions.
An example:
y = 2x + 5
if we are to predict the value of y at x = 3, we simply substitute 3 into x
y = 2(3) + 5
= 11
The equation describing the situation is given by
y - 0 = (5 - 0)/(47.5 - 0) (x - 0)
y = 5/47.5 x
y = 2/19 x
Therefore, it will require 19(11)/2 = 104.5 minutes to jog 11 miles.
Together they equal 90 degrees.
Equation:
(0.1x - 22) + (0.3x - 54) = 90
Open parenthesis and simplify:
0.4x -76 = 90
0.4x = 166
DIvide:
Your final answer is x= 415
Hope this helps!
E = 2 + 1/4 n
n = 40
E = 2 + 1/4(40)
E= 2 + 10
E = 12

2 x w
Explanation:
2w js just the same as 2 x w. You both multiply the variablw by 2.
Someone pleaase correct me if i an wrong!
If i’m right, a branliest would be nice!!
