Gina Wilson all things algebra unit 4 homework 3 questions 12-15
Step-by-step explanation:
the essential thing to remember here (and please, burn this into your brain for life) : the sum of all angles in a triangle is always (really always) 180 degrees.
therefore, in 12 and 13 we only need to add all 3 angles, and their sum must be 180.
from there we get really all 4 answers.
the next thing to consider is when a triangle had two equal angles, then it is an isoceles triangle (the 2 sides leading away from these 2 angles are equally long). that gives us the answers for 14 and 15.
12.
3x + 18 + 7x - 58 + 2x - 8 = 180
12x - 48 = 180
12x = 228
x = 19
angle A = 3x+18 = 3×19 + 18 = 57+18 = 75 degrees
angle B = 7x-58 = 7×19 - 58 = 133-58 = 75 degrees
angle C = 2x-8 = 2×19 - 8 = 38 - 8 = 30 degrees
13.
8x - 17 + 19x + 4 + 5x + 1 = 180
32x - 12 = 180
32x = 192
x = 6
angle Q = 8x-17 = 8×6 - 17 = 48-17 = 31 degrees
angle R = 19x+4 = 19×6 + 4 = 114+4 = 118 degrees
angle S = 5x+1 = 5×6 + 1 = 30+1 = 31 degrees
14.
KL = 9x - 14
LM = 7x - 37
KM = 3x + 23
angle K = angle L
so, the sides LM and KM must be equally long. that gives us
7x - 37 = 3x + 23
4x = 60
x = 15
KL = 9x-14 = 9×15 - 14 = 135-14 = 121
LM = 7x-37 = 7×15 - 37 = 105-37 = 68
KM = 3x+23 = 3×15 + 23 = 45+23 = 68
15.
XY = 13x - 21
YZ = 8x - 6
XZ = x + 4
angle X = angle Z
so, the sides XY and ZY (or YZ) must be equally long. that gives us
13x - 21 = 8x - 6
5x = 15
x = 3
XY = 13x-21 = 13×3 - 21 = 39-21 = 18
YZ = 8x-6 = 8×3 - 6 = 24-6 = 18
XZ = x + 4 = 3+4 = 7

Step-by-step explanation:
Fiona earns $10 for mowing each lawn and $5 per hour for her work. Write an inequality to show how many lawns she needs to mow in order to earn at least $135.
Answer: [tex]\geq[/tex] 9 lawns, assuming Fiona spends 1 hour per lawn.
Step-by-step explanation:
Let Y = the amount earned from mowing a lawn. Let z be the number of hours worked on that lawn.
Y = $10 + $5(z)
We need to know the number of hours, z, for any particular lawn to be able to make this a valid equation. Not having that, we really can't set up a valid equation.
But let's assume z=1 for each and every lawn and see what we'd have.
Y = $10 + $5
Y = $15/lawn.
Fiona needs at least $135 for her Broadway ticket.
Let L be the number of lawns mowed. We need:
L*($15/lawn) [tex]\geq[/tex] $135
L [tex]\geq[/tex] 9 lawns

Step-by-step explanation:Which pair of sneakers has the lowest sale price?
A) 20% off $35
B) 10% off $29
C) 15% off $30
D) 30% off $38
15% off $30 has lowest sale price. Therefore, option C is the correct answer.
What is sale price?A sale price is the discounted price at which goods or services are being sold.
A) 20% off $35
20/100 ×35
= 0.2×35
=$7
Sale price =35-7=$28
B) 10% off $29
10/100 ×29
= 0.1×29
= 2.9
Sale price =29-2.9
= $26.1
C) 15% off $30
15/100 ×30
= 0.15×30
= 4.5
Sale price =30-4.5
= $25.5
D) 30% off $38
30/100 ×38
= 0.3×38
= $11.4
Sale price=38-11.4
= $26.6
Therefore, option C is the correct answer.

Answer:
54 degrees
Step-by-step explanation:
First, I need to find the value of t.
So, I create an equation. Angle BPK is a right angle, so I can just add the two inner angles and set it equal to 90.
(8t + 6) + (3t + 18) = 90
Now, just solve for t.
11t + 24 = 90
11t = 66
t = 6
Finally, substitute 6 in for t.
8(6) + 6
48 + 6

I need help on Tales mathemathics below on image
Answer:
x=5
Step-by-step explanation:
i'm assuming the upper left expression is x-1 and that the 3 horizontal lines are parallel
the three horizontal lines seem to be parallel, so we have (x-1)/6 = 6/(x+4). cross multiply to get (x-1)(x+4) = 36, or x^2 +3x - 4 = 36. subtract 36 from both sides to get x^2 + 3x -40 = 0, factor or use the quadratic formula to get (x+8)(x-5)=0, so x=-8 or x=5, since we are looking for a length x can't equal -8, so x=5,

Answer:
7 T-Shirts
Step-by-step explanation:
Given:
100 Dollar
30 = sweater
42 = Jeans
4 each = t-shirts
Solution:
30+42 = 72

100 (total) - 30 (sweater) - 42 (jeans) = 28 (for shirts)
28 (money) / 4 (shirt cost) = 7 (shirts)
Assuming no tax and stuff, Maria should be able to by 7 shirts on top of her other items.
