Answer:
Slope is -3
Step-by-step explanation:
(0, -2) and (1, -5)
m= (y2-y1)/(x2-x1)
m= (-5+2)/(1-0)
m=( -3)/1
m = -3
Answer:
27 degrees and 63 degrees
Step-by-step explanation:
Let n be the number.
Angle 1: 2n-15
Angle 2: 3n
If the angles are complementary they add up to 90.
Therefore we can write an equation.
2n-15+3n=90
Combine like terms
5n-15=90
Add 15 to both sides
5n=105
n=21
Now we plug 21 in for n and solve for the angles
Angle 1 = 2(21)-15
Angle 1 = 42-15
Angle 1 = 27
Angle 2 = 3(21)
Angle 2 = 63
18-12+7
6 + 7
13
Write an equation.
Subtract first- the customer buys 12 black neon tetra fish which means subtraction
addition- the store clerk puts in 7 more black neon tetra fish which means your gonna add 7
Answer:
66
Step-by-step explanation:
So to find the mean you add up all the numbers (or the exam scores) which will get you 212 then you take the number and divide it by the total numbers in the set (how many numbers did you add up?)
212 divided by 8 is 26.5 which would be C. I hope this helps!
