A company that bottles mustard is allowed to advertise their bottle size as 21 ounces as long as the actual amount in the bottle is within
0.15 ounces of that amount. Which inequality shows all the possible actual bottle volumes (1) that the manufacturer would be able to advertise
as 21 ounces?
Answer:
d
Step-by-step explanation:
v+21
[tex]v + 21 \leqslant 0.15[/tex]
The inequality is v+ 21 ≤ 0.15
What is inequality?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
A company that bottles mustard is allowed to advertise their bottle size as 21 ounces as long as the actual amount in the bottle is within 0.15 ounces of that amount.
So,
if the volume is v then the situation can be represented as
v+ 21 ≤ 0.15
As, the actual amount is within 0.15 ounces of that amount.

If R is the midpoint of QS, find QS. (2x + 16) and (5x - 17) Brainliest to correct answers. Please no spamming or random answers this is due tmrw thx.
Answer:
QS = 76
Step-by-step explanation:
Given R is the midpoint of QS , then
RS = QR , that is
5x - 17 = 2x + 16 ( subtract 2x from both sides )
3x - 17 = 16 ( add 17 to both sides )
3x = 33 ( divide both sides by 3 )
x = 11
Then
QS = QR + RS
= 2x + 16 + 5x - 17
= 7x - 1
= 7(11) - 1
= 77 - 1
= 76
If △ABC is translated down nine unit(s) and to the right two unit(s), which
of the following would be the new coordinates of point A?
Answer:
A'(2, -5)
Step-by-step explanation:
we only need to focus on point a (0,4). The translation is moved 9 units down and 2 units to the right, so point (x,y) would become (x+2, y-9). plug 0 and 4 in for x and y respectively, and you get (0+2, 4-9) = (2, -5)

what is the value of x?
a. -5
b. -1/5
c. 5
d. 1/5
Answer:
d) 1/5
Step-by-step explanation:
5(x + 1) - 8 = 5x(2-4)
5x+5-8 = 5x(-2)
5x-3=-10x
15x = 3
x = 1/5
Answer:
d. 1/5Step-by-step explanation:
5(x + 1) - 8 = 5x(2-4)
=> 5x + 5 - 8 = 10x - 20x
=> 5x + 20x - 10x = 8 - 5
=> 15x = 3

Answer: -16d³ + 3d² - 3d + 2
Step-by-step explanation:
Given expression
(4d - 6d³ + 3d²) - (10d³ + 7d - 2)
Expand parentheses

20. Your friend says the absolute value equation |2x + 9 + 7 = 3 has two solutions
because the constant on the right side of the equation is positive. Is your friend
correct? Explain.
This is an absolute value problem. In mathematics, absolute value is simply defined as the distance of a number from zero on the number line, irrespective of the direction on either side of zero.
In the absolute value given which is; |2x + 9| = -4, we can see that there is an absolute value when the right hand side is negative and not when it is only positive.
Thus, the friend is not correct.We are given the equation;
|2x + 9| + 7 = 3
Now when dealing with absolute values, it means that the solution is either positive or negative.
For example;
|x| = 5 means that x = +5 or -5
Thus in this question, let us first of all simplify the equation to get;
|2x + 9| = 3 - 7
|2x + 9| = -4
From |2x + 9| = -4, we can see that there is an absolute value when the right hand side is negative and not when it is only positive.
Thus, the friend is not correct.

Please explain. I think it’s a two step equation.
Answer:
[tex] k = \dfrac{5}{3} [/tex]
Step-by-step explanation:
It is actually a one-step equation.
If you have a number multiplying a variable equaling another number, then you need to do only one operation to solve; you need to multiply both sides by the reciprocal of the number multiplying the variable.
Here we have
[tex] \dfrac{3}{2} = \dfrac{9}{10}k [/tex]
First, switch sides to have the variable, k, on the left side.
[tex] \dfrac{9}{10}k = \dfrac{3}{2} [/tex]
You have a variable, k, multiplied by a number, the fraction 9/10, equaling another number, 3/2. To solve for k, multiply both sides by the reciprocal of 9/10 which is 10/9.
[tex] \dfrac{10}{9} \times \dfrac{9}{10}k = \dfrac{10}{9} \times \dfrac{3}{2} [/tex]
On the left side, you have the product of two reciprocals, 10/9 and 9/10, which equals 1, leaving just k.
On the right side, you must multiply the fraction 10/9 by 3/2 and then reduce.
[tex] k = \dfrac{30}{18} [/tex]
[tex] k = \dfrac{5}{3} [/tex]
