Find x in the following solution: x+x+10+2x-6=180
Answer:
X = 44
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x=44
Step-by-step explanation:
First you add the all the x's.
4x+10-6=180
Then you subtract 6 from 10
4x+4=180
Next, you add subtract 4 from both sides.
4x=176
Divide by 4 and you get 44.
176/4
x=44

Find f(9) if f(x) = 2x+6
Answer:
24
Step-by-step explanation:
To do this all you need to do is replace x with 9
F(9) = 2(9) + 6
2 x 9 = 18
18 + 6 = 24

Answer:
17
Step-by-step explanation:
Let's solve your equation step-by-step.
6x+78=180
Step 1: Subtract 78 from both sides.
6x+78−78=180−78
6x=102
Step 2: Divide both sides by 6
6x/6=102/6
x=17
Answer:
x = 17
Step-by-step explanation:
If you subsitute x in "2x" you get 34. If you subsitute x for "4x - 4" you get 64.
After subtracting 180 from 98 you get 82. Add up 34, 64, and 82 then you get 180.
Two pounds of grapes cost $6.
Complete the table showing the price of different amounts of grapes at this rate.
What number belongs in the leftmost empty cell?
What number belongs in the rightmost cell?
Answer:
leftmost empty cell: ⅓
rightmost empty cell: 3
Step-by-step explanation:
✔️If 2 pounds grapes cost $6, then x pounds of grapes cost $1.
Thus;
2 : 6 = x : 1
2/6 = x/1
Multiply both sides by
²/6 × 1 = x/1 × 1
²/6 = x
¹/3 = x
x = ⅓
✔️If 2 pounds grapes cost $6, then 1 pound of grapes cost $x.
Thus;
2 : 6 = 1 : x
²/6 = ¹/x
Cross multiply
2x = 6
Divide both sides by 2
2x/2 = ⁶/2
x = 3

Vrite and simplify an expression to find he total cost of x pencils , 1 poster board , and (x + 1) notebooks.
Answer:
The expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:
[tex]C=xp+b+nx+n[/tex]
Step-by-step explanation:
Consider '[tex]x[/tex]' be the number of pencils which were bought
Consider '[tex]p[/tex]' denotes the cost of [tex]1[/tex] pencil
Consider '[tex]b[/tex]' denotes the cost of [tex]1[/tex] poster board
Consider '[tex]x+1[/tex]' be the number of notbooks which were bought
Consider '[tex]n[/tex]' denotes the cost of [tex]1[/tex] notebook
As we have to find the total cost. Let 'C' denotes the total cost
so the expression becomes
[tex]C=xp+b+\left(x+1\right)n[/tex]
simplifying
[tex]C=xp+b+nx+n[/tex]
Therefore, the expression to find the total cost of x pencils, 1 poster board, and (x + 1) notebooks will be:
[tex]C=xp+b+nx+n[/tex]

zer elevation
Function 2: The function below shows the number of feet that Sam's friend, Arthur, has left to climb

Who climbs at a faster rate? Make sure to explain your answer and how you know
Answer:
Start at -150, then add 3(-5), then add 122.2. -150 + 3(-5) + 122.2 = -45.3.
The answer is -45.3 feet depth. while minus sign shows the descend under the water with water surface as starting point.
Step-by-step explanation:
Initial depth of diver under the water =-150feet=−150feet
Diver descends 5 feet per minute for 3.5 minutes =3.5*(-5)=3.5∗(−5)
=-17.5=−17.5
Note: minus sign shows that the diver is under the water.
Diver ascends =122.2feet=122.2feet
Now adding all the terms a below as a numerical expression.
Current Depth of Diver after he descends 5 feet for 3.5 minutes and ascend 122.2 feet after =-150-17.5+122.2=−150−17.5+122.2
=45.3feet=45.3feet
By taking the initial depth of diver from which we add or subtract the changes made when he ascends or descends in the water to get the current depth.

Use the figure and given angle to find the measure of each angle below (tell me how many degrees it is).
9514 1404 393
Answer:
∠6 = ∠4 = 84°
∠5 = ∠3 = 96°
Step-by-step explanation:
Angle 4 and the marked angle (84°) are corresponding angles, so are congruent. Angles 4 and 6 are vertical angles, so are congruent.
∠6 = ∠4 = 84°
Angle 3 and the marked angle are a linear pair, so angle 3 is the supplement of 84°:
∠3 = 180° -84° = 96°
Angle 3 and angle 5 are alternate interior angles, so are congruent.
∠5 = ∠3 = 96°

Step-by-step explanation:
54n + 4.25n = 58.25n
1 - 3 = -2
(since the 2 is in parenthasis you will be subtracting instead of adding)
32p - 2p = 30p

Out of 10 marbles in a bag, 2 of them are blue. If you drew a marble at random 40 times, replacing it each time, how many times would you expect to draw a blue marble?
Answer:
8
Step-by-step explanation:
8 times would you expect to draw a blue marble.
What is Probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given:
Total marbles = 10
Blue marbles=2
Number of times= 40
So, the number of times would you expect to draw a blue marble
=2/10 *40
=80/10
=8
Hence, 8 times would you expect to draw a blue marble.
