Answer:
18 and 13
Step-by-step explanation:
The two numbers are 13 and 18 respectively.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the difference of two integers is 5. Twice the smaller integer is 8 more than the larger integer.
Assume the number to be [x] and [y]. We can write -
x - y = 5
2y = x + 8
2y = 5 + y + 8
y = 13
Then -
x = 13 + 5
x = 18
Therefore, the two numbers are 13 and 18 respectively.

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.

12

At what value of x do the graphs of the equations below intersect?
-2x +y = -6
1x + 2y = -2
They intersect at an x value of
Answer:
They intersect at an x value of 2
Step-by-step explanation:
Rewrite the equations into slope y-int form:
-2x + y = -6
y = 2x - 6
x + 2y = -2
2y = -2 - x
y = -1/2x - 1
Next, set the two equations as equal and solve for x:
2x - 6 = -1/2x - 1
2x + 1/2x = -1 + 6
4x + x = -2 + 12
5x = 10
x = 2

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
3x = 15
x = 5
This is the method that can be used to solve problems of this nature.
What is the value of x in the solution to this system of equations?
3x−6y=45

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.

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.

Twice a number added to another number is 15. The sum of the two numbers is 11. Find the numbers. Write the numbers from least to greatest
Answer:
4 and 7
Step-by-step explanation:
There are probably several ways to do this but this is how I did it:
First, I listed all the number combinations, that added together equaled 11.
This is what it looked like:
1, 10
2, 9
3, 8
4, 7
5, 6
6, 5
7, 4
I stopped here since the next step would be to double the first number and 8*2 would already be more than 15.
Then, I doubled the first number and added the second number to it, when I saw that didn't equal 15, I eliminated that possibility and moved on to the next set of numbers. When I reached 4, 7 I saw that 4*2 equaled 8 and 8 plus 7 equals 15 so I had the answer.
There are probably much more efficient ways to do this but this is how I did it.
Hope it helped!
The first number is 4 and second number is 7.
Let us consider that first number is x and second number is y.
[tex]2x+y=15\\\\x+y=11[/tex]
Substitute [tex]y=11 - x[/tex]in equation [tex]2x+y=15[/tex]
[tex]2x+11-x=15\\\\x=15-11=4[/tex]

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]
The regular price of an electric scooter is $290. It is on
sale for 20% off. Sales tax is 7%. What is the cost of the
electric scooter after the discount and sales tax are
applied?
$232.00
$294.06
$310.30
$248.24
Answer:
The cost of the electric scooter after the discount and
sales tax will be: $248.24
Step-by-step explanation:
The regular price of an electric scooter = $290
Discount = 20%
The discount price = 20% × 290
= 20/100 × 290
= $58
The price after the discount = $290 - $58 = $232
Sales tax = 7%
Sales tax amount = 7% × 232
= 7/100 × 232
= $16.24
The cost after the discount and sales tax = $232 + $16.24
= $248.24
Thus, the cost of the electric scooter after the discount and
sales tax will be: $248.24
