1) Answer: x = 9
<u>Step-by-step explanation:</u>
Same Side Interior Angles are supplementary
15 + 5x + 14x - 6 = 180
19x + 9 = 180
19x = 171
x = 9
***************************************************************
2) Answer: x = 9
<u>Step-by-step explanation:</u>
Corresponding Angles are congruent
13x - 7 = 11x + 11
2x = 18
x = 9
***************************************************************
3) Answer: x = -10
<u>Step-by-step explanation:</u>
Alternating Interior Angles are congruent
90 = x + 100
-10 = x
***************************************************************
3) Answer: x = 7
<u>Step-by-step explanation:</u>
Alternating Exterior Angles are congruent
17x + 1 = 120
17x = 119
x = 7

Answer:
Step-by-step explanation:
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. Men have hip breadths that are normally distributed with a mean of 14.4 inches and a standard deviation of 1 inch. find P98. I really don't understand, help needed please.
-----------------------
Find the z-value with a left tail of 0.98
invNorm(0.98) = 2.0537
-----
Find the corresponding x-value using x = zs+u
----
x = 2.0537*1+14.4
---
x = 16.45 inches
=====================
14 + (-8) / 2 x -3
Follow order of operations: divide and multiply from left to right:
-8/2 = -4 x -3 = 12
Now you have 14 + 12
The answer is 26
Answer:
Step 1: 14x − 21 = 1; Step 2: 14x = 22
Explanation:
7(2x−3)=1
Step 1: Simplify both sides of the equation
7(2x−3)=1
(7)(2x)+(7)(−3)=1(Distribute)
14x+−21=1
14x−21=1
Step 2: Add 21 to both sides
14x−21+21=1+21
14x=22
Step 3: Divide both sides by 14
14x / 14 = 22 / 14
x = 22 / 14: x = 11/7
