P(z < 3)
From the normal distribution table,
P(z < 3) = 0.9987
5)
Equilateral triangle, all sides are equal
So 2x + 5 = 11
2x = 6
x = 3
Answer is the first one
3; Equilateral theorem
6)
Isosceles triangle has at least two congruent sides.
So 6x = 24
x = 4
Answer x = 4
Converse of the Base Angle Theorem
7)
5x + 7 = 52
5x = 45
x = 9
Answer
x = 9
Base angle theorem
8)
5y - 14 = 3y
2y = 14
y = 7
Answer
7; Equiangular theorem
Answer:
w=9
Step-by-step explanation:
Our equation is: 8w-15=57
Add 15 to both sides
-15 is now gone because we added 15 so it would be zero
and we have 72 because 15 plus 57 is 72
Now we have:
8w=72
Divide by 8 on both sides
8w cancels out to just w
and 72 divided by 8 is 9
And you're left with:
w=9
Answer:
y=-1/4x+2
Step-by-step explanation:
Answer:
-15 Is the answer
Step-by-step explanation:
(-5)(7)+4×5
= -15
(-5)(7) + 4×5 = -15/1 = -15
Multiple: -5 * 7 = -35
Multiple: 4 * 5 = 20
Add: the result of step No. 1 + the result of step No. 2 = -35 + 20 = -15
Hope this helps.
