K added to 10 gives you 4 times the value of K.
If you wanted to solve the expression:
Subtract both sides of the expression, right hand side(10+k) and left hand side(4K), by -k as you want to get rid of the variable to get simply 10 on the LHS.
10+k -k = 4k -k
If we want to subtract k from k then we get 0, and if we want to subtract k from 4k we get 3k. For the sake of simplicity think of k as an object saying if I subtract object A from object A I get zero, and so forth.
We are left with the expression:
10 = 3k
We divide both sides by 3 as to get rid of it from the RHS.
We get a solution 10/3 = k
Answer:
Step-by-step explanation:in standard form y= ax+b
-4y = -3x+28
4y =3x-28
or y= 3/4 x -7
So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)
Equation 3 is
y= 3/4x-2
which also has slope = 3/4 and y intercept = -2
Parallel lines have same slope
Similarly a perpendicular line will have slope of - 1/a
For equation
y= ax+b
Perpendicular line is
y=( -1/a) x +c
Answer:
5/12 = r
Step-by-step explanation:
-1/3 = r - 3/4
+3/4 +3/4
5/12 = r
Answer:
90cm
Step-by-step explanation:
1/3 of a day = 30cms
3/3 of a day = 30 * 3 cms = 90 cms
