Step-by-step explanation:
Since all angles in a triangle add up to 180 degrees, all you need to do to find the 1 missing angle is to subtract the given values from 180.
17) 180 - 25 - 102 = 53
Angle Q = 53 degrees
18) 180 - 46 - 34 = 100
Angle E = 100 degrees

Which graph shows the solution to this system of inequalities? y>-1/3x+1 y>2x-3
Answers
Answer:
Graph A.
Step-by-step explanation:
We don't even have to analyze the inequalities. It tells us that y is supposed to be bigger than something and that y is supposed to be bigger than something else. That means that for both lines, the shaded region must be upwards. The only graph that conforms to that is graph A.

What is the percent of increase of Stephen's height?
A. 17.00%
B. 26. 15%
C. 35.42%
D. 73.85%
Answers
Answer:
35.42%
Step-by-step explanation:
Answer:
C. 35.42%
Step-by-step explanation:
65 - 48 = 17
Since he grew 17 inches, you must figure out what percentage 17 is of 48.
17/48 = 1/100 (represents decimal)
Cross multiply: 17 ⋅ 100 = 1700 and 48 ⋅ 1 = 48
Divide: 1700/ 48
= 35.41666666666667
Round to the nearest hundredth:
= 35.42

Answer:
the probability is 13/25

Ian is borrowing $1000 from his parents to buy a notebook computer. He plans to pay them back at the rate of $60
per month. Ken is borrowing $600 from his parents to purchase a snowboard. He plans to pay his parents back at
the rate of $20 per month. a) Write an equation that can be used to determine after how many months the boys will owe the same amount.
b) Determine algebraically and state in how many months the two boys will owe the same amount. State the
amount they will owe at this time.
c) Ian claims that he will have his loan paid off 6 months after he and Ken owe the same amount. Determine and
state if Ian is correct. Explain your reasoning.
Answers
A = 10 months
B = First part, the two equations:
Ian: y = 1000 - 60x, where x is the number of months and y is the remaining balance owed.
Ken: y = 600 - 20x.
They will be equal at 1000 - 60x = 600 - 20x
Second part: Solve the equation. Note, if you're equation is incorrect, solve it anyway because you will still get some credit!
1000 - 60x = 600 - 20x
1000 = 600 + 40x
400 = 40x
x = 10 months
y = 600 - 20(10) = 600 - 200 = $400 still owed.
C =
Solve Ian's equation for y = 0, when no money is owed.
1000 - 60x = 0
1000 = 60x
x = 16.66666.... or 17 months.
Ian will not be paid off 6 months after he and Ken owe the same amount. He will still owe money.
Alternatively, six months after 10 is 16 months,
and y = 1000 - 60(16) = 1000 - 960 = 40. He will still owe $40 at 16 months, so he is not paid off.
Is 1+4(3x-10)-12x equivalent to -39? Explain.
Answers
Step-by-step explanation:
1. Review a given problem : [tex]1+4(3x-10)-12x[/tex]
2.distributive property: [tex]4\left(3x-10\right) = 12x-40[/tex]
[tex]=1+12x-40-12x[/tex]
3. Simplify: [tex]1+12x-40-12x[/tex]
[tex]-39 +12x-12x[/tex]
[tex]=-39[/tex]
Cancel +12x and -12x since equals 0
1-40= -39
-39= -39
It is equivalent. Good luck.

The length of a rectangle is 3 cm less than its width what are the dimensions of the rectangle if its area is 270 cm²
Answers
Given:
The length of a rectangle is 3 cm less than its width.
The area of the rectangle is 270 cm².
To find:
The dimensions of the rectangle.
Solution:
Let x be the width of the rectangle. Then,
[tex]\text{Length}=x-3[/tex]
Area of a rectangle is:
[tex]\text{Area}=\text{Length}\times \text{width}[/tex]
[tex]270=(x-3)(x)[/tex]
[tex]270=x^2-3x[/tex]
[tex]0=x^2-3x-270[/tex]
Splitting the middle term, we get
[tex]x^2-18x+15x-270=0[/tex]
[tex]x(x-18)+15(x-18)=0[/tex]
[tex](x-18)(x+15)=0[/tex]
[tex]x=18,-15[/tex]
Width of the rectangle cannot be negative. So, the only value of x is 18.
[tex]Width=18[/tex]
[tex]Length=18-3[/tex]
[tex]Length=15[/tex]
Therefore, the length of the rectangle is 15 cm and the width of the rectangle is 18 cm.
