Answer:
6. B) 115
7. B) 180 - (180 - 90 + 30) = x
Step-by-step explanation:
8 21/100 is the mixed number for8.21
Answer:
-5/4 or -1.25
Step-by-step explanation:
the points are (-6, -3) and (-2, -8)
the formula for slope is y2-y1/x2-x1
y2 is -8
y1 is -3
x2 is -2
x1 is -6
(-8+3)/(-2+6)
(-5)/(4)
-5/4 or -1.25
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
Answer:
x = 44
right
Step-by-step explanation:
The sum of the angles in a triangle add to 180
90+ 46+x = 180
Combine like terms
136+x = 180
Subtract 136 from each side
136+x-136=180-136
x =44
Since we have a 90 degree angle it is a right triangle
