Answer:216 is your answer
Step-by-step explanation:
21) 3(2j-k)=108 It is asking you to set the equation equal to j
distribute the 3
6j-3k=108
move k to the other side by adding on both sides
6j=108+3k
divide everything by 6
j=18+0.5k
It has line symmetry and rotational symmetry, so A is the answer, hope this helps
2/5 x 60 = 24
2/5 x (4x - 1) = x+5
8x - 2 = 5x + 25
3x = 27
x = 9
The value of x is 9
Answer:
y=-3x-1
Step-by-step explanation:
12x+4y=-4
Slope intercept y=mx+b
Subtract 12x from both sides
4y=-4-12x
Divide each side by 4
y=-1-3x then just reorder to match slope intercept form
y=3x-1
