Drag the symbol to complete the solution to this inequalities
Answer:
x ≤ 13.2.
Step-by-step explanation:
6 ≥ x/2.2
Multiply both sides by 2.2:
6 * 2.2 ≥ x
x ≤ 13.2.
The solution to the inequality is [tex]x \leq 13.2[/tex], the correct symbol used in blank is ≤.
To complete the solution to the inequality [tex]6 \geq \frac{x}{2.2}.[/tex]
Rearrange the inequality as follows:
[tex]\frac{x}{2.2} \le 6[/tex]
The solution to the inequality is:
[tex]x \leq 13.2[/tex]
Comparing the expression [tex]\frac{x}{2.2}[/tex] to 6, we can see that [tex]\frac{x}{2.2}[/tex] should be less than or equal to 6 in order for the inequality to hold true.
Therefore, the correct symbol to place in the blank is "≤" and solution is [tex]x \leq 13.2[/tex].

What are the solutions of 16p^2 - 64 = 0
Answer:
p = 2 or p = -2
Step-by-step explanation:
Solve for p over the real numbers:
16 p^2 - 64 = 0
Hint: | Factor constant terms from the left hand side.
16 p^2 - 64 = 16 (p^2 - 4):

Divide both sides by 16:
p^2 - 4 = 0
Hint: | Using the quadratic formula, solve for p.
p = (0 ± sqrt(0^2 - 4 (-4)))/2 = ( ± sqrt(16))/2 = ( ± 4)/2 = ± 2:

Solve the system of equations - 8x - 5y = -13 and - 4x – 5y = 11 by
combining the equations.
Answer:
(6,-7)
Step-by-step explanation:
subtract them:
-8x - 5y = -13
-4x - 5y = 11
you get
-4x = -24
so x = 6
plug x into the second equation:
-24 - 5y = 11
-5y = 35
y = -7
so your solution is (6,-7).
Answer:
Your solution is (6, -7).
Step-by-step explanation:
Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.
-8x - 5y = -13
-4x - 5y = 11
Let's change the second equation into one with one variable on each side.
-5y = 4x + 11
y = -4/5x - 11/5
Now, plug this into your first equation.
-8x - 5(-4/5x - 11/5) = -13
Distribute the -5 sign.
-8x + 4x + 11 = -13
Combine the like terms.
-4x + 11 = -13
-4x = -24
Isolate x by dividing both sides by -4.
x = -24/-4
x = 6
Now plug this back into either equation.
y = -4/5(6) - 11/5
Multiply.
y = -24/5 - 11/5
Subtract.
y = -35/5
Simplify.
y = -7
Your solution is (6, -7).
Check this by plugging in these values into the equation you have not checked yet.
-8(6) - 5(-7) = -13
-48 + 35 = -13
-13 = -13
Your solution is correct.

Please help me! STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.
Answer:
x = 12
ST = 23 units
SU = 23 units
TU = 23 units
Step-by-step explanation:
For an equilateral triangle, all the angles are equal. Also, all the sides are equal.
Hence given that the sides ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x
ST = 2x - 1
SU = 5x - 37
TU = x + 11
Since ST = SU = TU
2x - 1 = 5x - 37
collect like terms
37 - 1 = 5x - 2x
36 = 3x
Divide both 3
36/3 = x
x = 12
Therefore
ST = 2x - 1 = 2(12) - 1 = 23 units
SU = 5x - 37 = 5(12) - 37 = 23 units
TU = x + 11 = 12 + 11 = 23 units

Ines has saved $5. She doubles the amount she saves each week. Does the function have a constant difference or a constant ratio? Does this represent an exponential function?
Answer:
The function have a constant ratio
No, it does not represent an exponential function.
Step-by-step explanation:
As given,
Ines has saved $5. She doubles the amount she saves each week.
⇒ In first week she saved = $5
In second week she saved = 2×$5 = $10
In third week she saved = 2×$10 = 20
In fourth week she saved = 2×$20 = 40
and so on..
∴ we get the series
5, 10, 20, 40 ,.......
If the series is given as a, b, c, d, ..... , then
The common difference is defined as d = b-a = c-b
The common ration is defined as r = [tex]\frac{b}{a} = \frac{c}{b}[/tex]
Here, in the given question
The series is - 5, 10, 20, 40
This has no common difference , d = 10 - 5 (= 5 )≠ 20 - 10 (= 10)
As 5 ≠ 10
So the function does not define common difference .
Now,
This has common ratio , r = [tex]\frac{10}{5} (=2) = \frac{20}{10}(=2)[/tex]
As 2 = 2
So, the function represent common ratio
Now,
The function does not represent an exponential function because it is increased by common ratio.

Step-by-step explanation:
Write a ratio, in the simplest form and a percent for the shaded area (there's a 5x4 box and 6 cubes are shaded)
Answer:
[tex]\%Percent = 30 \%[/tex]
Step-by-step explanation:
Given
[tex]Shaded = 6\ cubes[/tex]
[tex]Box = 5\ x\ 4[/tex]
Required
Determine the percentage of the shaded cubes
First, we calculate the number of boxes:
[tex]Box = 5\ x\ 4[/tex]
Express as multiplication
[tex]Box = 5\ *\ 4[/tex]
[tex]Box = 20[/tex]
This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:
[tex]\%Percent = \frac{Shaded}{Box} * 100\%[/tex]
[tex]\%Percent = \frac{6}{20} * 100\%[/tex]
[tex]\%Percent = \frac{6* 100}{20} \%[/tex]
[tex]\%Percent = \frac{600}{20} \%[/tex]
[tex]\%Percent = 30 \%[/tex]
30% were shaded
