For all of these you're trying to solve for the variable. The variable is usually a number or symbol.
11) -44+n=36
Step one would be to add 44 to both sides of the equation.
N=80
12) -36=p-91
Step one would be to add -91 to both sides of the equation.
P=55
13) X-225=671
Step one you be to add 225 to both sides of the equation. Although it may seem difficult because of the big numbers, it's the same technique.
14) 19=c-(-12)
Step one on this equation will be a little different. Because there are two negative signs (-), they turn into a plus sign. Remember, two negative signs make a positive sign.
19=c+12
Now you just subtract 12 from each side of the equation.
6=C
The correct answer is
<span>D. The number of degrees in its supplement
The size of the sides and the rotation is irrelevant and would still keep the angle having the same size. The number of degrees in the supplement decides how big an angle is because the larger the supplementary angle the smaller the angle we're observing will be, and vice versa.</span>
It is B.
The underlined ≥ symbols a closed circle, and any number bigger than 3 if you multiply it with 4 and solve the equation, your answer would be reasonable
Answer:
y=-4/5 x + 7
Step-by-step explanation:
Subtract 8 x by 8 x. Do not put 8 x under 10 y or 70.
Then divide 10 by all of the terms.
Then you have: y= 7 - 8/10 x
But then you have to flip 7 and - 8/10 x
And get y= -8/10 x + 7
Simplified is y= 4/5 x + 7
REMEMBER: y=m x + b
M= Slope
B= y-intercept
1. Mean.
2. <span>Standard deviation.
First we have to square each value and calculate the mean of that squares:
so the variance:
and the standard deviation:
