40% of 400 would be 160.
40% is 0.4 
so
0.4*400 = 160
to prove my work
400/160 = 0.4 = 40%

40% of 400
percent means parts out of 100
40%=40/100=0.40

'of' means multiply
40% of 400 means
0.4 times 400=160

there's an easier way to do it
40% of 100=40
times 4 both sides
40% of 400=160

Make x the subject y=3x-2
Sedaia [141]
First, let's add the two from both sides.
y + 2 = 3x - 2 + 2
y + 2 = 3x

Now, all we have to do is to divide both sides by 3.
(y + 2)/3 = (3x)/3
(y + 2)/3 = x

And now, flip both sides around so it looks nicer.
x = (y + 2)/3

Can someone help me with this question? <br> (2,5) and (10,3) What is the slope and the y-intercept
Paha777 [63]

Answer:

slope is -1/4

y intercept is 11/2

Step-by-step explanation:

the slope is (3-5)/(10-2) = -2/8 = -1/4 (using the slope formula)

the y intercept we can set up an equation, y= mx + b

we already know m, which is -1/4 (the slope), and to find b, we could just plug in one of the points to get

5 = (-1/4)*2+b

solve the equation

b = 11/2
