Step-by-step explanation:
Write a simplified expression for the right half of the equation that can be used to find the nth term in the sequence The sequence is 7,9,11,13,15
7,9,11,13,15
First, find the common difference (d)
9-7 = 11-9 = 13-11 = 15-13 = 2
d= 11
a1 = first term = 7
apply the formula:
an = a1 + (n-1) d
an = 7 + (n-1) 2
an = 7 + 2n-2
an = 2n + 5
let p represenst "angke A is an obtuse angle" and q represent " the measure of angle A = 75 degrees. convert the symbolic statement to a sentence.
In this scenario, we are considering if-then statements. Looking at the given statement,
p = angle A is an obtuse angle
q = the measure of angle A = 75 degrees
A statement of if q, then p would be
q - p
where - is an arrow pointing to the right
Looking at the picture, the symbol before p represents negation. It tells us that
if q, then not p. By translation, the correct answer would be
If the measure of angle A = 75 degrees, then angle A is not an obtuse angle

Answer:
Step-by-step explanation:
Yes, you can use either the system of elimination, substitution, or graphical method to solve linear equations
How to substitute 8x-4y=-12, 8x+y=-17
we have the system
8x-4y=-12 -----> equation A
8x+y=-17 -----> y=-17-8x -----> equation B
substitute equation B in equation A
8x-4(-17-8x)=-12
solve for x
8x+68+32x=-12
40x=-12-68
40x=-80
x=-2
Find the value of y
y=-17-8(-2)
y=-17+16
y=-1
the solution is x=-2y=-1Example8x-4y=-12 -----> equation A8x+5y=-17 -----> equation B
isolate the variable y in equation B (or equation A)
5y=-17-8x
y=-(17/5)-(8/5)x
substitute in equation A
8x-4[-(17/5)-(8/5)x ]=-12
solve for x

Step-by-step explanation:
Determine the property, definition, postulate, or theorem that bestjustifies each statement.Given: AC = BD; AB = 3x - 2; CD = 10ABсD If AC = AB + BC and AC = BD.then AB + BC =BD
The given statement is
[tex]AC=AB+BC\rightarrow AC=BD,then,AB+BC=BD[/tex]As you can observe, the observe, we made a substitution. However, the exact property used here is the transitive property of equalities, that's the property responsible for the substitution in mathematics.
Therefore, the answer is the transitive property of equalities.The area of a triangle is 50
the length is x+10 and the width is x
solve for x.
In a rectangle of area 50 the value of x is 5
How to solve for xArea of a rectangle is given by multiplication of the length and the width
Area was given as 50
length = x + 10
width = x
Area = L * w
50 = (x + 10) * x
50 = x^2 + 10x
rearranging the equation
x^2 + 10x - 50
factorizing gives
x - 5x + 10x - 50
x(x- 5) + 10(x - 5)
(x - 5)(x + 10)
therefore
x = 5 or x = -10
taking the positive value
x = 5

An explicit formula for the sequence -2,3,8,13,18 is aₙ = 7 - 5n.
The express method for a mathematics collection is an = a + (n - 1)d, and any time period of the collection can be computed, without knowing the opposite terms of the collection. In preferred, the explicit method is the nth time period of mathematics, geometric, or harmonic sequence.
Calculation:-
a₁ = 2
a₂ = 2 - 5 = -3
a₃ = -3 - 5 = -8
a₄ = -8 -5 = -13
a₅ = -13 -5
= -18
The formula for the nth term of explicit sequence is aₙ = a₁ +(n - 1)d
where a₁ = 2 and d = 5
So,
aₙ =2 + (n - 1)(-5) using distributive property
aₙ = 2 + n (-5)+(-1)(-5)
aₙ = 2 - 5n + 5
aₙ = 7 - 5n

Answer:
x=223.96
Step-by-step explanation:
Answer as a decimal: x=223.96
Answer as a fraction: x= 223 24/25
Let's solve this equation step-by-step!
5(x−225)=−5.2
Step 1: Simplify both sides of the equation.
5(x−225)=−5.2
(5)(x)+(5)(−225)=−5.2 (Distribute)
5x+−1125=−5.2
5x−1125=−5.2
Step 2: Add 1125 to both sides.
5x−1125+1125=−5.2+1125
5x=1119.8
Step 3: Divide both sides by 5.
5x/5=1119.8/5
