1) -5 + w/3 = -1
w/3 = -1 + 5
w = 4*3
w = 12
2) 24-3x = -27
-3x = -27 - 24
3x = 51
x = 51/3
x = 17
3) <span>-17 + n/5 = 33
n/5 = 33 + 17
n = 50 * 5
n = 250
4) A) </span><span>3m + 2 = -10
5) </span><span>25 = -75 - 5x
-5x = 25 + 75
x = 100 / -5
x = -20
6) D) </span><span>5 - 7x = 2
Hope this helps!</span>
Answer:
96.
Step-by-step explanation:
If the remainder is 0 when dividing by 6 the number must be a multiple of 6.
There is no 2 digit number ending in 9 divisible by 6 because that number is odd. So 9 must be the first digit.
The only number it can be is 96.

Step-by-step explanation: Hey for the second one I got y = -3/4x -0.5 I'm not sure if its correct though sorry if not
ill try my best to explain my solution though
1. From the parallel equation (3x + 4y = 12) all we need to do is find the slope
So the easiest way to do so is to put the said equation in <u>y-intercept </u>form
y=mx +b
m= slope
b= y intercept
so 1. 3x + 4y = 12
=
4y = 12-3x
divide that by 4 to get only y
y=3-3/4x
-3/4 is our slope
y=-3/4x+b
than we have a point -2, -2
if we put -2 for y
-2=-3/4x+b
and then we put our -2 for x
-2 = -3/4 * -2 + b
=
-2 = -1.5 +b
b=-0.5
Answer : y=-3/4x-0.5
The empirical rule states that at 95% the measurements would be within 2 standard deviations of the mean.
You are given a mean of 68 inches and a standard deviation of 4.
2 times the standard deviation = 2 x 4 = 8
So 95% of the heights would be between 68-8 = 60 inches and 68+8 = 76 inches.
