Answer:
When solving for x in the following equation: -6x + 18 = -6
step 1: -6x +18 - 18 = -6 - 18 (subtract 18 from both side)
step 2. -6x/-6 = -24 / -6 (divide both sides by -6 to isolate x by itself)
x = 4
Step-by-step explanation:
The value of x in the expression - 6x + 18 = - 6, is 4.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given an expression - 6x + 18 = - 6 solving for x is the same as finding the value of x.
∴ - 6x + 18 = - 6.
- 6x = - 6 - 18.
- 6x = - 24.
6x = 24.
x = 4.

One-half divided by 4 =
.
Answer:
1/8 half-gallon or 1/16 full gallon
Step-by-step explanation:
Emma and her 3 friends= Four people
Four people shared 1/2 gallon= 1/2 divided by 4
1/2 divided by 4= 1/8
Each person got 1/8 of the half gallon.
This would mean that out of a FULL gallon, they would get 1/16

When asked to find the value of x for
which f(x)=17, Danny answered 39. What
mistake did Danny make? What is the
correct answer?
Answer and Step-by-step explanation:
We are not given the function in question, but in order to explain, will form a function. Suppose f(x) = 3x + 2.
If f(x) = 17, then
3x + 2 = 17, to find the value of x, we have solve for x in the equation.
3x = 17 – 2

swimming pool is being filled with a hose. The hose fills the pool at a constant rate. The pool's water level rises 4 inches in hours. What rate per hour of the water level change?
The required rate of the level of change of water in the swimming pool is 1 / 3 level per hour.
Given that,
The swimming pool is being filled with a hose.
The pool's water level rises 4 inches in hours.
To determine the rate per hour of the water level change.
Here,
Let 1 level of pool = 1 feet = 12 inches
The pool's water level rises 4 inches in hours. So, ti will rises 12 inches in 3 hours, which implies level change after 3 hours
Now the rate of level change of water = 1 / 3 level per hour
Thus, the required rate of the level of change of water in the swimming pool is 1 / 3 level per hour.

2x + y - z = 15

solve the system of equations
Answer:
The given system of equations is :
2x + 3y + 5z = 1 -> eq. (1)
3x + 2y + z = 5 -> eq. (2)
Multiplying eq. (1) with 3 and eq. (2) with 2, we get :
6x + 9y + 15z = 3 -> eq. (3)
and, 6x + 4y + 2z = 10 -> eq. (4)
respectively.
Subtracting eq. (4) from eq. (3) :
5y + 13z = -7 -> eq. (5)
Multiplying eq. (1) with 2 and eq. (2) with 3, we get :
4x + 6y + 10z = 2 -> eq. (6)
and, 9x + 6y + 3z = 15 -> eq. (7)
respectively.
Subtracting eq. (7) from eq. (6) :
-5x + 7z = -13 -> eq. (8)
Let z = t, where t is a parameter.
We can write eq. (5) and eq. (8) as :
5y + 13t = -7 & -5x + 7t = -13
i.e., 5y = -7 - 13t & 5x = 13 + 7t
y = -(7/5) - (13t/5) & x = (13/5) + (7t/5)
Therefore, the solution for the given system of equations is :
x = (13/5) + (7t/5)
y = -(7/5) - (13t/5)
z = t
where, t can take any value.

Mike has a credit rating of 720. Tyler has a credit rating of 560. Mike and Tyler apply for identical loans from Park Bank. Mike is approved for a loan at 3.2% interest, and Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating. What interest rate is Tyler charged?
Answer:
6.2%
Step-by-step explanation:
Credit rating is an evaluation of the credit risk of a borrower, that how often a person is going to repay their debt, by credit rating it predicts the ability of the debtor to payback.
Mike has credit rating = 720
Tyler has credit rating = 560
Both are approved for loan. Mike's Credit score is higher, which means he is a much safer debtor as compared to Tyler. Mike will be able to pay back much easily than Tyler. Therefore Mike interest rate is 3.2%
Interest rate of Tyler is higher as he is not that trusted and has low Credit rating. Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating so it interest on the loan will be
Interest = 3.2%+3% = 6.2%

Three partners in a business receive profits in the ratio 2 : 4 : 8. A fourth partner automatically receives $50,000 profit. The company during the year has a profit of $400,000. What are the amounts for the other three partners?
Please answer ASAP, whoever answers correctly will get BRAINLIEST!!!
The amounts for the other three partners are $25000, $100000, and $200000.
How to compute the value?The amount that the other people will share will be:
= $400000 - $50000
= $350000
Therefore this will be divided as follows:
A = 2/(2+4+8) × $350000
= 2/14 × $350000
= $25000
B = 4/14 × $350000
= $100000
C = 8/14 × $350000
= $200000
Therefore, the amounts for the other three partners are $25000, $100000, and $200000.

Which equation in slope-intercept form represents a line that passes through the point (2,3) and is
perpendicular to the line y - 9 = (0 + 7)?
Answer:
The answer is below
Step-by-step explanation:
Which equation in slope-intercept form represents a line that passes through the point (2,3) and is perpendicular to the line y−9=23(x+7)
Solution:
The equation of a line in slope intercept form is given as y = mx + b, where m is the slope and b is the y intercept.
Given a line y−9=23(x+7)
y - 9 = 23x + 161
y = 23x + 170. The slope of this line comparing with y = mx + b gives m = 23
Two lines are perpendicular if the product of their slope gives -1.
Let [tex]m_1[/tex] be the slope of the perpendicular line, hence:
[tex]m_1(23)=-1\\\\m_1=\frac{-1}{23}[/tex]
Since the perpendicular line passes through (2, 3), we can get its equation using:
[tex]y-y_1=m_1(x_x_1)\\\\y-3=\frac{-1}{23}(x-2)\\\\y= \frac{-1}{23}x+\frac{2}{23}+3\\\\ y= \frac{-1}{23}x+\frac{71}{23}[/tex]

Caroline’s Coffee Shop sells a refill mug for $8.95. Each refill costs $1.50. Last month Sean spent $26.95 on a mug and refills. How many refills did he buy?
Answer:
Alright! First you'd have to subtract the flat fee of the mug which is $8.95, then you'd have to divide by the rate which is $1.50. Your equation would be:
(26.95 - 8.95) ÷ 1.50 = r
Then you solve using your head.. lol.
(26.95 - 8.95) = 18.
(18 ÷ 1.50) = 12.
R = 12.
