Answer:
A
Step-by-step explanation:
The statement that If p → q and q are true, then p is true which is the correct answer would be an option (A).
What is the conditional statement?A conditional statement is defined as the two fundamental components that make up a conditional statement are Hypothesis (if) and Conclusion (then).
Let us consider the example to understand the parts of a conditional statement.
Conditional Statement: If today is Friday, then yesterday was Thursday.
Hypothesis: "If today is Friday."
In the given problem,
Conditional Statement: If p → q and q are true, then p is true,
Hypothesis: "If p → q and q are true"
Hence, the statement that If p → q and q are true, then p is true which is the correct answer would be option (A)

Answer:
1. 18
2. 15
3. Symmetric Property
Step-by-step explanation:
1. 8 + 10 = 18
2. Following symmetric prop. of eq. would mean that since 8 + 10 = 15 + 3 and 8 + 10 = 18, 15 + 3 = 18 as well
3. Symmetric Property of Equality states that if a = b, then b = a
george started a coin collection. his dad gave him 75 coins. each month he will add 20 coins. Which equation can be used to find y, the total number of coins in george's collection after x months? A. y = 75x + 20x By = 20x + 75 C. y = 75x - 20 D. 20x - 75
Answer: B
Step-by-step explanation: Hope this helps!
he got a one time thing of 75 coins and now gets 20 coins for each month which explains 20x. (X being the number of months)
The equation that could be used for determining the y should be option B y = 20x + 75
Calculation of an equation:
Since dad gave him 75 coins. each month he will add 20 coins.
Here we assume a number of months be x
So, the equation is
y = 20x + 75
Therefore, we can conclude that The equation that could be used for determining the y should be option B y = 20x + 75

Answer:
As follows,
Step-by-step explanation:
You can solve these either by factoring or using the quadratic formula or other ways,
1. x^2+2x+1=0
Factoring,
(x+1)^2=0
x+1=0
x=-1
2.y^2-y-2=0
Using quadratic formula,
(-b±√(b^2-4ac))/2a
(--1±√(-1^2-4*1*-2))/2*1
(1±√(1+8))/2
(1±√(9))/2
(1±3)/2
y=(1±3)/2
y=(1+3)/2 y=(1-3)/2
y=4/2 y=-2/2
y=2 y=-1
3.y^2+y+1=0
Using quadratic formula,
(-b±√(b^2-4ac))/2a
(-1±√(1^2-4*1*1))/2*1
(-1±√(1-4))/2
(-1±√(3))/2
No real roots
4. x^2+9x+18=0
Using quadratic formula,
(-9±√(9^2-4*1*18))/2*1
(-9±√(81-72))/2
(-9±√(9))/2
(-9±3)/2
x=(-9+3)/2 x= (-9-3)/2
x=-6/2 x=-12/2
x=-3 x=-6
5.x^2+5x+6=0
Using quadratic formula,
(-5±√(b^2-4ac))/2a
(-5±√(5^2-4*1*6))/2*1
(-5±√(25-24)/2
(-5±1)/2
x=(-5+1)/2 x=(-5-1)/2
x=-4/2 x=-6/2
x=-2 x=-3
6. 3n^2-13n-10=0
Using quadratic formula,
(-b±√(b^2-4ac))/2a
(-(-13)±√(-13^2-4*3*(-10)))/2*3
(13±√(169-(-120))/6
(13±√289)/6
The discriminant b^2−4ac>0
So there are 2 real roots.
x=(13±17)/6
x=30/6 or x=-4/6
x=5 or x=-2/3

What is the value of x?
Enter your answer in the box.
Answer:
x = 50
Step-by-step explanation:
→ Make the equations equal to each other
2 ( x + 10 ) = 3x - 30
→ Expand brackets
2x + 20 = 3x - 30
→ Minus 3x from both sides
-x + 20 = -30
→ Minus 20 from both sides
-x = -50
Opposite angles are equal
[tex]\\ \sf\longmapsto 2(x+10)=3x-30[/tex]
[tex]\\ \sf\longmapsto 2x+20=3x-30[/tex]
[tex]\\ \sf\longmapsto 3x-2x=30+20[/tex]
[tex]\\ \sf\longmapsto x=50[/tex]
94. Birth Rate of Unmarried Women In the United States, the birth rate B of unmarried women (births per 1000 unmarried women) for women whose age is a is modeled by the function B(a) = -0.33a + 19.17a-213.37. (a) What is the age of unmarried women with the highest birth rate? 29.0 years (b) What is the highest birth rate of unmarried women? (e) Evaluate and interpret B(40).
Using concepts of quadratic equation, we have that:
a) The age of unmarried women with the highest birth rate 29 years.
b) The highest birth rate of unmarried women is of 65 births per 1000 unmarried women.
c) B(40) = 25.43, which means that the birth rate of unmarried women of age 40 is of 25.43 births per 1000 unmarried women.
The birth-rate for women of age a is given by:
[tex]B(a) = -0.33a^2 + 19.17a - 213.37[/tex]
Which is a quadratic equation with coefficients [tex]a = -0.33, b = 19.17, c = -213.37[/tex]
Item a:
The age with the highest value is the a-value for the vertex, which is:
[tex]a_V = -\frac{b}{2a} = -\frac{19.17}{2(-0.33)} = 29[/tex]
The age of unmarried women with the highest birth rate 29 years.
Item b:
The rate is B(29), which is:
[tex]B(29) = -0.33(29)^2 + 19.17(29) - 213.37 = 65[/tex]
The highest birth rate of unmarried women is of 65 births per 1000 unmarried women.
Item c:
[tex]B(40) = -0.33(40)^2 + 19.17(40) - 213.37 = 25.43[/tex]
B(40) = 25.43, which means that the birth rate of unmarried women of age 40 is of 25.43 births per 1000 unmarried women.

Answer:
[tex]x=89[/tex]
Step-by-step explanation:
We can plug into the formula for the mean to get [tex](87+73+84+82+x)/5=83[/tex].
We can combine like terms on the left side to get [tex](326+x)/5=83[/tex].
We can multiply by [tex]5[/tex] on both sides to get [tex]326+x=415[/tex].
We can finally subtract [tex]326[/tex] from both sides to get [tex]x=89[/tex].
So, the answer is [tex]\boxed{x=89}[/tex] and we're done!
