-8(6x+12)=-32x-24 SHOW YOUR WORK PLS whats x
Answer:
x= -9/2
Hope I helped
Answer:
[tex]x=-\frac{9}{2}[/tex]
Step-by-step explanation:
Simplify the given equation by solving for x. Isolate the x variable in:
[tex]-8(6x+12)=-32x-24[/tex]
Expand the left side by using the distributive property. Remember that when a negative and positive are multiplied, the result is always negative:
[tex]-8(6x)-8(12)=-32x-24\\\\-48x-96=-32x-24[/tex]
Use inverse operations to isolate the variable. Add 96 to both sides, canceling out the -96 on the left:
[tex]-48x-96+96=-32x-24+96\\\\-48x=-32x+72[/tex]
Add 32x to both sides to isolate x:
[tex]-48x+32x=-32x+32x+72\\\\-16x=72[/tex]
Now divide both sides by 16:
[tex]\frac{-16x}{16} =\frac{72}{16} \\\\-x=\frac{9}{2}[/tex]
Make the variable positive by multiplying both sides by -1:
[tex]-1(-x)=-1(\frac{9}{2})\\\\x=-\frac{9}{2}[/tex]
:Done
Note:
You do the same thing to both sides in order to keep the equation balanced. Using the opposite value of a term cancels it out, moving it to the other side.
Marcy's Cafe has regular coffee and decaffeinated coffee. This morning, the cafe served 60 coffees in all, 33 of which were regular. What percentage of the coffees were regular?
Answer:
55%
Step-by-step explanation:
Percentage of regular coffees = [tex]\frac{33}{60}[/tex] × 100%
= 55%
Answer:
55%
Step-by-step explanation:
To find the percentage of regular coffees, divide 33 by 60, and multiply that by 100:
(33/60) x 100
0.55 x 100
= 55
So, 55% were regular

A ski jump rises 3ft over a run of 7ft what is the length of the surface of the jump?
Answer:
7.6158 feet
Step-by-step explanation:
The rise and run form the shorter sides of a right triangle with the hypotenuse as the surface (see figure)
Hypotenuse (surface length) is given by the Pythagorean formula
[tex]c = \sqrt{a^2 + b^2}[/tex] where c is the hypotenuse and a, b the shorter sides
Here
[tex]\sf c = \sqrt{7^2 + 3^2} = \sqrt{49 + 9} = \sqrt{58} = 7.6158\;feet[/tex]

When Jose installs a new app on his phone, it creates a square icon on his home screen. The square starts with
side lengths of 1 cm. The side lengths grow by 2.8 cm each second until the square reaches its maximum size.
What is the perimeter of the square after 1.5 seconds? Recall that the perimeter of a shape is the sum of its side
lengths.
O16.8 centimeters
O 19.2 centimeters
O 20.8 centimeters
O 29.2 centimeters
Lo
Answer:
O 20.8 centimeters
Step-by-step explanation:
Guessed on Edge and got it right.
The perimeter of the square after 1.5 seconds will be 20.8 centimeters so option (C) will be correct.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
Perimeter of square = side + side + side + side
Initial side length of square = 1 cm
Rate of grow side = 2.8 centimeter per minutes
By multiplying 1.5
Rate of grow side = 4.2 centimeter per 1.5 minute
So,
New side = 1 + 4.2 = 5.2 cm
Perimeter = 4 × side
Perimeter = 4 (2.5) = 20.8 cm
Hence "The perimeter of the square after 1.5 seconds will be 20.8 centimeters".

Mental Math Determine whether each statement is always, sometimes, or never true.An absolute value function of the form f(x) = c|x| is symmetric about the y-axis.
The statement that "an absolute value function of the form f(x) = c|x| is symmetric about the y-axis" is always true.
How to determine whether each statement is always, sometimes, or never true?The function is given as
f(x) = c|x|
The parent absolute value function is represented f(x) = |x|
Also, the parent absolute value function is symmetric about the y-axis.
This is also true for all functions that take the form f(x) = c|x| where c does not equal 0
Hence, the statement that "an absolute value function of the form f(x) = c|x| is symmetric about the y-axis" is always true

Answer:-4
Step-by-step explanation:
If the measure of angle DBC = (12x - 3), the measure of angle DBE = (5x + 12), and the measure of angle EBC = (3x + 13), find the measure of angle EBC.
Consider the below figure attached with the question.
Given:
m∠DBC = (12x - 3), m∠DBE = (5x + 12), m∠EBC = (3x + 13).
To find:
The measure of ∠EBC.
Solution:
From the figure, it is clear that,
[tex]m\angle DBC-m\angle DBE=m\angle EBC[/tex]
Putting the given values, we get
[tex](12x-3)-(5x+12)=(3x+13)[/tex]
[tex]12x-3-5x-12=3x+13[/tex]
[tex]7x-15=3x+13[/tex]
[tex]7x-3x=15+13[/tex]
[tex]4x=28[/tex]
Divide both sides by 4.
[tex]x=7[/tex]
Now,
[tex]m\angle EBC=(3x+13)^\circ[/tex]
[tex]m\angle EBC=(3(7)+13)^\circ[/tex]
[tex]m\angle EBC=(21+13)^\circ[/tex]
[tex]m\angle EBC=34^\circ[/tex]
Therefore, the measure of angle EBC is 34 degrees.

The hare challenged the tortoise to a rematch race. This time, the hare ran the same speed of 15 meters per second the whole race. The hare didn't even take nap this time. To be nice, the hare gave the tortoise a head start. The tortoise started 200 meters ahead. The tortoise ran 7 meters per second. Create a system of equations to model this situation.
Answer:
[tex]\left \{ {{h=15s} \atop {t=7s+200}} \right.[/tex]
Step-by-step explanation:
Let [tex]h[/tex] be equal to the number of meters the hare travels.
Let [tex]t[/tex] be equal to the number of meters the tortoise travels.
Let [tex]s[/tex] be equal to the number of seconds that pass.
The hare travels at a speed of 15 meters per second, which means [tex]15s[/tex] represents the number of meters the hare travels depending on the number of seconds that pass.
[tex]h=15s[/tex]
The tortoise travels at a speed of 7 meters per second, which means [tex]7s[/tex] represents the number of meters the tortoise travels depending on the number of seconds that pass.
[tex]t=7s[/tex]
However, because the tortoise got a 200-meter head start, we need to add 200 meters to our equation.
[tex]t=7s+200[/tex]
Here is our system of equations:
[tex]\left \{ {{h=15s} \atop {t=7s+200}} \right.[/tex]

I WILL GIVE BRAINLIST TO FIRST PERSON WHO ANSWERS!!!!
Answer:
its c
Step-by-step explanation:
Our denominators are 40 and 4. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 40 and 4. In this case, the lowest common denominator is 40.
If we multiply the first denominator (40) by 1 we will get 40. If we multiply the second denominator (4) by 10 we will also get 40. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:
33 x 1
40 x 1
3 x 10
4 x 10
This is what 33/40 and 3/4 looks like with the same denominator:
33
40
&
30
40
Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 33 is greater than 30 which also means that 33/40 is greater than 3/4.
