solve the liner equation 3(2x-14)+x=15-(-9x-5)
PLEASE HELP! DO NOT PUT A SILLY AWSER I WILL REPORT YOU!
Answer:
x= -31
Step-by-step explanation:
Let's solve your equation step-by-step.
3(2x−14)+x=15−(−9x−5)
Step 1: Simplify both sides of the equation.
3(2x−14)+x=15−(−9x−5)
3(2x−14)+x=15+−1(−9x−5)(Distribute the Negative Sign)
3(2x−14)+x=15+−1(−9x)+(−1)(−5)
3(2x−14)+x=15+9x+5
(3)(2x)+(3)(−14)+x=15+9x+5(Distribute)
6x+−42+x=15+9x+5
(6x+x)+(−42)=(9x)+(15+5)(Combine Like Terms)
7x+−42=9x+20
7x−42=9x+20
Step 2: Subtract 9x from both sides.
7x−42−9x=9x+20−9x
−2x−42=20
Step 3: Add 42 to both sides.
−2x−42+42=20+42
−2x=62
Step 4: Divide both sides by -2.
−2x
−2
=
62

x=−31

A store sells a 33-pound bag of oranges for \$ 3.60$3.60 and a 55-pound bag of oranges for \$ 5.25$5.25. What is the difference between the price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges?
Answer:
0.01364
Step-by-step explanation:
It is given that,
A store sells a 33-pound bag of oranges for $3.60 and a 55-pound bag of oranges for $5.25.
Price per pound of 33 pound bag is 3.60/33 = 0.10909 price per pound
Price per pound of 55 pound bag of oranges is 5.25/55 = 0.09545 price per pound
Difference between price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges is :
D = 0.10909 - 0.09545
D = 0.01364
Therefore, this is the required solution.

Hello.
The answer is choice A. angle 1 = 118, angle 2 = 118
Explanation:
The four angles above are congruent (meaning the same) to the ones beneath.
Angles 1 and 2 are also congruent, so they will measure the same.
Lets label the angles above A, B, C, D. B being the known angle, which is 118°. The angles beneath can be labelled E, F, G, H.
∠B ≅ ∠D
∠ABCD ≅ ∠EFGH
∠BD ≅ ∠FH
FH (or 1 and 2) equal 118.

In △FGH, FH ≅ FG. Which angles are congruent? Select both angles that are congruent
angles FGH and FHG
Step-by-step explanation:
Since this is a triangle, and the question states that FH=FG, you know that the triangle is an isosceles triangle. If you use an isosceles triangle, you know that the bottom two angles are the same degrees. Since the F is the same for both lines, you can determine that F is the top point of the triangle. As such, is you draw the triangle out, you will find the answer is angles FGH and FHG

The domain is the set of values for which the given function is defined. The domain of the given function is 0≤x≤7.5. The correct option is B.
What is the domain and range of a function?The domain is the set of values for which the given function is defined.
The range is the set of all values which the given function can output.
Given that function b model the bagel inventory, b(x), after x hours of opening, and it is given as,
b(x) = 75 - 10x
Now, the domain of the function is the values that x can take in the function. Since x represents the number of hours after opening, therefore, it can not be negative and must start with zero.
Further, since the inventory or the total number of bagels that the shop has is 75, therefore, they can not sell more than that, and at some point, the inventory will become zero. Therefore, we can write,
75 - 10x = 0
-10x = -75
10x = 75
x = 75 /10
x = 7.5 hours
Hence, the domain of the given function is 0≤x≤7.5.

In a function the x values cannot repeat. Look at each answer choice and see if an x repeats:
The first choice (top left) has the x value, -6, repeating. It cannot be a function.
The second choice (top right) does not have an x value repeat. This makes it a function!

Me up rich goes to the skate park and tents a skateboard for 4.00 per hour they make him rent a helmet for one time 6.00 fee if he only has $30 to spend at the park then select the equation that can be used to calculate h the number of hours he can rent the skateboard
Let, x be the maximum hours he can rent skate board and helmet.
So, total price :
T = 4x + 6x
Now, it is given that he has only $30.
Therefore,
Total price should be less than or equal to $30.
4x + 6x ≤ 30
10x ≤ 30
x ≤ 3
Therefore, the maximum number of hours he can rent the skateboard is 3 hours.
Hence, this is the required solution.

Let's see what to do buddy...
_________________________________
Step (1)
We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :
[tex](n - 2) \times 180[/tex]
Our figure has 5 sides ;
So , sume the interior angles of it equals :
[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]
_________________________________
Step (2)
First look at the photo which I post.
According it we have :
[tex](180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\ [/tex]
[tex]2x - x + 475 - 10 = 540[/tex]
[tex]x + 465 = 540[/tex]
Subtract the sides of the equation minus 465 :
[tex]x = 540 - 465[/tex]
[tex]x = 75[/tex]

And we're done.
