Answer:
3x + 4 = 7
Step-by-step explanation:
Equations contain an equal sign, but expressions only contain numbers and variables.
The expression in option A) is not an expression as it is a equation.
What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here, option A as 3x+4=7 thus it is an linear equation but an expression is a polynomial where there are no signs such as<,>=
Hence, Option A is the correct answer.

Mrs.Rose received a 35% discount on her cell phone. The price of her cell phone came out to be $180. How much was the original price of her cell phone?
Answer:
The original price of the cell phone is $514.29
Step-by-step explanation:
The answer is $514.29 because the equation to find the answer is :
Let x = the original price of the cell phone
$180 = Price after discount
So, 180 = x * 35/100
Multiply by its reciprocal on both sides so
180 (100/35) = x
18000/35 = x
514.29 = x
So the original price of the cell phone is $514.29

Help please. Sort the numbers.
Answer:
1) 2² + 3² - 2 = 4 + 9 - 2 = 11
3² + 2² - 3 = 9 + 4 - 3 = 10
2) 4(3²) + 3(2) + 3 = 36 + 6 + 3 = 45
4(2²) + 3(3) + 3 = 16 + 9 + 3 = 28
3) 2(3) + 3 + 1 = 10
4) 3(2²) + 2(3) + 2 = 12 + 6 + 2 = 20
3(3²) + 2(2) + 3 = 27 + 4 + 3 = 34
5) 2⁴ - 3² + 3 = 16 - 9 + 3 = 10
6) 2³ - 2(3)(3) - 5 = 8 - 18 - 5 = -15
3³ - 2(3)(3) - 5 = 27 - 18 - 5 = 4
1) x = 3, y = 2
2) neither
3) x = 2, y = 3
4) neither
5) x = 2, y = 3
6) neither

Answer:
[tex]a_n=-8+(n-1)-7[/tex]
Step-by-step explanation:
General arithmetic sequence formula: [tex]a_n=a_1+(n-1)d[/tex]
where [tex]a_1[/tex] = first term, and d = common difference.
The first term is -8
And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.
To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula
General formula: [tex]a_n=a_1+(n-1)d[/tex]
We have [tex]a_1=-8[/tex] and d = -7
So the formula to find the nth term would be
[tex]a_n=-8+(n-1)-7[/tex]
