Answer:
X = (J+M)/K
Step-by-step explanation:
Undo what has been done to the variable, in reverse order. The variable has been multiplied by K and M subtracted from the result. So, we first add M (to undo the subtraction), then we divide by K (to undo the multiplication).
KX = J +M . . . . . . M added to the given equation
X = (J + M)/K . . . . the result of that is then divided by K
___
Since these are all capital letters, we might assume they represent vectors and/or matrices. If so, the "divide by K" step needs to be "multiply on the left by K^-1, the matrix inverse of K."
Then your solution looks like
X = K⁻¹·(J + M)
Answer:
a particular class of 31 students, 12 are men. What fraction of the students in the class are women.
okay so first things first where it says like g(x) = blah blah blah. you have to go down th like g(10) and plug it in g(10) = -3(10)+1. (Hope that makes since) and the answer for that one would be 31
It’s the first one, so you’re correct
The percent discount is: 20%
Step-by-step explanation:
The formula for percentage will be used to find the percentage of discount.
Given
Original price = $160.95
Discounted price = $128.44
The discount is:
D = Original price - sale price
The percent discount is given by:
Rounding off to nearest whole percent
20%
Hence,
The percent discount is: 20%
