Hello! :)
To solve your equation, we will first simplify both sides of the equation
-7 = -1 + x/3
-7 = -1 + 1/3x
-7 = 1/3x - 1
Next, we will flip the equation
1/3x - 1 = -7
Third, we will add 1 to both sides
1/3x - 1 + 1 = -7 + 1
1/3x = -6
Last, we will Multiply both sides by 3
3 * (1/3x) = (3) * (-6)
x = -18 (ANSWER)
That means -18 is you answer

Six times the sum of a number and four
Answer:
6*(x+4)
Step-by-step explanation:
The expression "Six times the sum of a number and four" can be written as 6 × (x + 4) OR 6(x+4)
The complete question is:
How do you write the expression for: Six times the sum of a number and four
To write an expression for the given statement (Six times the sum of a number and four),
Let the number be x
Therefore, the sum of the number and four would be
x + 4
Now, for the complete statement - Six times the sum of a number and four
We will get
6 × (x + 4) OR 6(x+4)
Hence, the expression "Six times the sum of a number and four" can be written as 6 × (x + 4) OR 6(x+4)

Hello!
The new value is $ 22,9425 or just $ 23 in a more simplified size.
We need to calculate 25% of 30.59.
We will do this by turning 25 into tenths:
0,25 × 30,59= 7,6475Now, we subtract that from 30,59.
30,59 - 7,6475
= 22,9425
So, the new value is $ 22,9425 or just $ 23 in a more simplified size.

Harlon wrote the equation uppercase A = 18 (x squared + 1) to find the area of a rectangle that has a length of x squared + 1 and a width of 18. He solved for x and got x = plus-or-minus StartRoot StartFraction uppercase A Over 18 EndFraction minus 1 EndRoot Which of the following is an equivalent equation for x?
Answer: x= a-18/18
Step-by-step explanation:
The expression equivalent to this is letter A. x= ±√(A-18/18)
What are equivalent expressions?Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.
To derive equivalent expressions of some expression, we can either make it look more complex or simple. Usually, we simplify it.
To solve for x in the equation for the area which was given to be;
A = 18(x^2 + 1),
So, we divide both sides of the equation by 18 first.
A/18 = x^2 + 1
Then, we subtract 1 from both sides of the equation;
A/18 – 1 = x^2
Then, we simplify the expression in the left side of the equation;
(A – 18)/18 = x^2
And obtain the square root from both sides of equation,
x= ±√(A-18/18)
Therefore, The expression equivalent to this is letter A. x= ±√(A-18/18)

Here are the first five terms of a number sequenceS . 10 16 22 28 34 Find an expression, in terms of n , for the nth term of this sequence.
Answer:
t = 4 + 6n
Step-by-step explanation:
a = 10
d = 6
in general
tn = a + (n-1)*d
tn = 10 + (n-1)*6
tn = 10 + 6n - 6
tn = 4 + 6n
So if n = 5 then
t5 = 4 + 6*5
t5 = 4 + 30
t5 = 34 which agrees with your givens.
Cameron said that the Y intercept of a quadratic function always tells the maximum value of the function. explain Cameron's error
Answer:
We can have two cases.
A quadratic function where the leading coefficient is larger than zero, in this case the arms of the graph will open up, and it will continue forever, so the maximum in this case is infinite.
A quadratic function where the leading coefficient is negative. In this case the arms of the graph will open down, then the maximum of the quadratic function coincides with the vertex of the function.
Where for a generic function:
y(x) = a*x^2 + b*x + c
The vertex is at:
x = -a/2b
and the maximum value is:
y(-a/2b)

A) -2 1/2 x
B) -x
C) 2x
D) 3/4 x
Answer:
(-5 x)/2
Step-by-step explanation:
Simplify the following:
-6 (x/4 - (2 x)/3 + (5 x)/6)
Put each term in x/4 - (2 x)/3 + (5 x)/6 over the common denominator 12: x/4 - (2 x)/3 + (5 x)/6 = (3 x)/12 - (8 x)/12 + (10 x)/12:
-6(3 x)/12 - (8 x)/12 + (10 x)/12
(3 x)/12 - (8 x)/12 + (10 x)/12 = (3 x - 8 x + 10 x)/12:
-6(3 x - 8 x + 10 x)/12
The gcd of -6 and 12 is 6, so (-6 (3 x - 8 x + 10 x))/12 = ((6 (-1)) (3 x - 8 x + 10 x))/(6×2) = 6/6×(-(3 x - 8 x + 10 x))/2 = (-(3 x - 8 x + 10 x))/2:
(-1 (3 x - 8 x + 10 x))/2

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of pieces be = A
Let the number be = 1/4
Now , the number of pieces of 1/4 in 5 3/4 is calculated as
The number 5 3/4 is converted into mixed fraction is 23/4
So , the equation is
The number of pieces of 1/4 x n = 23 / 4
So , the equation will be
n x 1/4 = 23 / 4 be equation (1)
Multiply by 4 on both sides , we get
n = 23 pieces
Therefore , the number of pieces 1/4 is in 5 3/4 is 23 pieces

Answer:
Well first we have to know what -12 is -4. So I know that 8 subtracting 12 is -4 already but, i am explaining to your knowlege so here I go.
What we can do is add 12 to -4 and it will equal what _-12=-4
So -4+12=8
Since the variable is with 8, we have to find what the variable w is. So 8x_=8?
Thats obvious right? 8x1=8!
So 8w-12=-4 = 8x1=8-12=-4

purchases. Write an equation that models his total cost for the day.
Step B: How many cards did Brian purchase if he spent a total of $29?
Step C: If Brian brought a total of $65, what is the maximum amount of cards he can purchase?
Explain why in a short paragraph and in your own words.
Answer:
Step-by-step explanation:
let x be the number of cards brian gets
let y be the amount of money he spends
the y intercept will be 5, since he automatically spends $5 to enter
a. 4x+5=y
b.29=4x+5 —-> 24=4x —-> x=6. Brian got 6 card
c. Brian can’t buy more than 15 cards. When you plug in 65 for y into the equation, after solving for x you get 15 To check, 4(15)+5=65

&//&18289
If X = 37.5% of 20% of 48 and Y = 14.28% of 27.27% of 77, then X>Y.
The first step is to determine the value of X.
X = 37.5% of 20% of 48
X = 0.375 x 0.2 x 48 = 3.6
The second step is to determine the value of Y.
Y = 14.28% of 27.27% of 77
Y = 0.1428 x 0.2727 x 77 = 3

Given the functions f(x) = −3x + 51 and g(x) = 3x − 9, find the value of x for which f(x) = g(x).
The value of x for which f(x) = g(x) is x
PLS ANSWER ASAP
Answer:
x = 10
Step-by-step explanation:
Step 1: Define
f(x) = -3x + 51
g(x) = 3x - 9
f(x) = g(x)
Step 2: Set up equation
f(x) = g(x)
-3x + 51 = 3x - 9
Step 3: Solve for x
51 = 6x - 9
60 = 6x
x = 10
Step 4: Check
f(10) = -3(10) + 51
f(10) = -30 + 51
f(10) = 21
g(10) = 3(10) - 9
g(10) = 30 - 9
g(10) = 21
f(10) = g(10) = 21
