Solve for x: 3x−2=8x+8
Answer:
-2 =x
Step-by-step explanation:
3x−2=8x+8
Subtract 3x from each side
3x-3x−2=8x-3x+8
-2 = 5x+8
Subtract 8 from each side
-2-8 = 5x+8-8
-10 = 5x
Divide each side by 5
-10/5 = 5x/5
-2 =x
Answer:
-2
Step-by-step explanation:
Subtract 8x from both sides.
3x−2−8x=8x+8−8x
−5x−2=8
Step 2: Add 2 to both sides.
−5x−2+2=8+2
−5x=10
Step 3: Divide both sides by -5.
−5x
−5
=

Use the associative property to create equivalent expressions to a + b + (c + d). Which statements are true? Check all that apply. The associative property allows us to change the grouping of terms that are added together. When changing the grouping, the order of the terms stays the same; only the parentheses change position. The expression a + (b + c) + d is an equivalent expression. The expression ab(cd) is an equivalent expression. The expression (a+ b) + c + d is an equivalent expression. The expression a + b(c + d) is an equivalent expression.
Answer:
a.The associative property allows us to change the grouping of terms that are added together.
b.When changing the grouping, the order of the terms stays the same; only the parentheses change position.
c.The expression a + (b + c) + d is an equivalent expression.
e.The expression (a+ b) + c + d is an equivalent expression.
Step-by-step explanation:
The correct statements are statement first, statement second, statement third, and statement fifth are correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
As we know,
The associative property allows us to change the grouping of terms that are added together.

Answer:
{x|-25<=x, 30>x} [-25, 30)
Step-by-step explanation:
Set notation is straightforward and just includes putting the lesser and greater signs. For the interval notation, square brackets are for less than and equal or greater than or equal, so I put one for -25. Parentheses are the opposite, only for strict greater or lesser than, so I put a parenthesis.

77 is written as the product of two prime numbers 7 × 11. Can 702 be written as the product of two prime numbers? If not, why? What about 703?
Answer:
702 can't be written as the product of 2 prime numbers because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore, 702 is a prime number.
The prime factorization of 703 is 19 × 37. Since it has a total of 2 prime factors, 703 is a composite number.

The maximum number of tickets to sell in one year if Each weekend, the theater can sell a total of 761 tickets for their performances, is 39572.
What is multiplication?The fundamental concept of making the same number of additions repeatedly is represented by the action of multiplication. The results of multiplying two or more integers are known as the products, and the factors that are used in the multiplication are referred to as the factors.
Given:
Each weekend, the theater can sell a total of 761 tickets for their performances,
The total number of weeks = 52,
Calculate the maximum number of tickets to sell in one year as shown below,
The maximum number of tickets to sell in one year = 52 × 761
The maximum number of tickets to sell in one year = 39572
Thus, the total number of tickets sold is 39572.

Hey there!
ANSWER: [tex]x<-100[/tex]EXPLANATION:[tex]13+15+18+\frac{x}{4} <21[/tex]
To get x, simplify both sides of the inequality.
[tex]\frac{1}{4}x+46<21[/tex]
Now we have to minus(subtract) 46 from both sides.
[tex]\frac{1}{4}x+46-46<21-46\\ =\frac{1}{4}x<-25[/tex]
In the last step, we'll have to multiply both sides by 4.

In the given figure, PQ=PR and QS is the bisector of angle PQR. If angle PQS=30°, find angle PSQ.
Answer:
90°
Step-by-step explanation:
PQ=PR ⇒
∠PQR = ∠PRQQS is the bisector of angle PQR ⇒
∠PQS= ∠RQSIf angle PQS=30°, find angle PSQ
∠PQS=30° ⇒
∠PQR = 2*∠PQS = 2*30° = 60°As ∠PQR = 60°,
∠PRQ = 60° and ∠QPR = 60° as remaining angleSo,
∠PSQ = 180° - (∠QPR + ∠PQS) = 180° - 90° = 90°5^6/5^2

what is a palindrome,armstrong,mersenne numbers?
Answer:
A numeric palindrome is a number that remains the same when its digits are reversed.
An Armstrong number of three digits is an integer such that the sum of the cubes of its digits is equal to the number itself.
A Mersenne prime is a prime number that is one less than a power of two.
Step-by-step explanation:
An example of a palindromic number is 16461.
371 is an Armstrong number since 3^3 + 7^3 + 1^3 = 371.
A Mersenne is a prime number of the form Mₙ = 2ⁿ − 1 for some integer n.
