Step-by-step explanation:
let the unknown be x
length = 3x
width = x
Perimeter = 2 lengths + 2 widths
24 ft = 3x + 3x + x + x
24 ft = 8x
3 ft = x
dimensions = length × width
= 3(3) × 3
= 9 ft × 3 ft
if you wanna check,
24 ft = 3(3) + 3(3) + 3 + 3
24 ft = 24
what is 3x + 9 =21 when x =4
Answer:
21
Step-by-step explanation:
Original Equation:
3x + 9 = 21
x = 4
Plug the value into the equation.
3 ⋅ 4 = 12
12 + 9 = 21
21 is the answer.

3x-3 (x+ 1) = 3
Answer:
The answer is~ no solution
Step-by-step explanation:
its no solution because
3x−3(x+1)=3
Step 1: Simplify both sides of the equation.
3x−3(x+1)=3
3x+(−3)(x)+(−3)(1)=3(Distribute)
3x+−3x+−3=3
(3x+−3x)+(−3)=3(Combine Like Terms)
−3=3
−3=3
Step 2: Add 3 to both sides.
−3+3=3+3
0=6

Finding the Slope of a Line from a Table
What is the slope of the linear function represented in
the table?
y
o
.
Answer:
m = rise / run = 1/7
Step-by-step explanation:
Recall that the slope of a line is m = rise / run.
Here we look at x first (to calculate the run): x begins at -7 and ends at 0. Thus, the run is 0 - (-7), or 7.
Now look at how y behaves (find the rise): y begins at 0 and ends at 1. Thus, the rise is 1.
Therefore the slope of the line connecting the two poings given is
m = rise / run = 1/7
Solve for x: −2(x + 3) = −2x − 6 NEED HELP PLZ:(
A: 0
B: 3 C:All real numbers
D:No solution
Answer:
The answer is C:All real solutions
Step-by-step explanation:
here are the steps in case u need them :)
Step 1: Simplify both sides of the equation.
−2(x+3)=−2x−6
(−2)(x)+(−2)(3)=−2x+−6(Distribute)
−2x+−6=−2x+−6
−2x−6=−2x−6
Step 2: Add 2x to both sides.
−2x−6+2x=−2x−6+2x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0
Answer:
C: All real numbers.
Step-by-step explanation:
-2 ( x + 3 ) = -2x -6
-2 times x, -2 times 3
-2x -6 = -2x -6
Add 6
-2x -6 +6 = -2x -6 +6
-2x = -2x

If a serving of yogurt is StartFraction 3 Over 8 EndFraction of a pound, to the nearest whole serving, how many servings of yogurt are in the container? 1 serving 2 servings 4 servings 5 servings
Answer:
4 servings
Step-by-step explanation:
Yogurt in the container = 1 5/8 pounds
A serving = 3/8 pounds
how many servings of yogurt are in the container?
Servings in the yogurt container = total yogurt in the container / yogurt per servings
= 1 5/8 ÷ 3/8
= 13/8 × 8/3

The temperature of an enclosure for a pet corn snake should be an average of 81° F. For the well-being of the corn snake, the temperature in the enclosure should not vary by more than 5° F. Which absolute value equation could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure?
Answer: |81-x|<5
Step-by-step explanation:
Given: Temperature of an enclosure for a pet corn snake should be an average of 81° F.
Temperature in the enclosure should not vary by more than 5° F.
Let x= Temperature in the enclosure
Then, difference between average and current temperature should less the 5.
i.e. |81-x|<5 (required absolute value equation )
hence, the absolute value equation could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure:
|81-x|<5
Using absolute value, it is found that the equation that could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure is:
[tex]|T - 81| = 5[/tex]
The absolute value function is defined by:[tex]|x| = x, x \geq 0[/tex]
[tex]|x| = -x, x < 0[/tex]
It measures the distance of a point x to the origin.In this problem, the temperature T should be within 5º F of 81ºF, hence, the absolute value of the difference between T and 81 should be of 5, that is:
[tex]|T - 81| = 5[/tex]

Tickets to a basketball game can be ordered online for a set price per ticket plus a $5.50 service fee. The total cost in
dollars for ordering 5 tickets is $108.00. Which linear function represents , the total cost, when x tickets are ordered?
c(x) = 5.50 + 20.50x
c(x) = 5.50x + 20.50
c(x) = 5.50 + 21.60x
c(x) = 5.50x + 21.60
Answer:
The correct linear function is c(x) = 5.50 + 20.50x.
Step-by-step explanation:
It's a linear function, so that means it uses y=mx+b. It says "per ticket" which means that the ticket cost is the slope, or m, of the equation. The service fee would be added on as a one-time fee, making it the y-intercept, or b. In order to find the cost of the tickets, you had to subtract the service fee from the total cost, then divide by how many tickets were purchased. You can set this up by plugging in what you know.
[tex]108=5.50+5x[/tex]
Subtract the 5.50 from both sides, leaving us with:
[tex]103.50=5x[/tex]
Now, this equation tells us how much 5 tickets cost, but we want how much it is per ticket. That means now we have to divide both sides by 5:
[tex]20.50=x[/tex]
Thus, one ticket is $20.50.
[tex]c(x)=5.50+20.50x[/tex]
The linear function is c(x) = 5.50x + 20.50
Let the cost of the tickets be represented by x
Therefore, 108 = 5.50 + 5x
Collect like terms
5x = 108 - 5.50
5x = 103.50
Divide both side by 5
5x/5 = 103.50/5
x = 20.50
Therefore, a ticket costs $20.50
In conclusion, the total cost, when x tickets are ordered will be c(x) = 5.50x + 20.50.

-t^2 + 12t = 32
Answer:
t = 8, t = 4
Step-by-step explanation:
-t² + 12t = 32
-t² + 12t - 32 = 0 (Subtracted 32 on both sides.)
t² - 12t + 32 = 0 (Divided by -1 on both sides.)
(t - 8)(t - 4) = 0 (Factor.)
t - 8 = 0 t - 4 = 0

Find the value of x
12x
6x+28
Your answer
Step-by-step explanation:
Hey there!
By looking at the figure, the given "2x" and "6x + 28" are co-interior angle.
So,
2x + 6x + 28 = 180°. ( sum of co-interior angle is 180°)
8x + 28°=180°
8x = 180° - 28°
8x = 152°
[tex]x = \frac{152}{8} [/tex]
X = 19°
Therefore, X = 19°.
Hope it helps...
Answer:
x=19
Step-by-step explanation:
These are same-side interior angles. The Same-Side Interior Angles Theorem states that if two parallel lines are cut by a transversal, then the same side interior angles are supplementary. This means that the sum of the two angles is equal to 180°.
2x+6x+28=180°
8x=180-28
8x=152
x=19

What is the solution to the following system of equations?
X - 3y = 5
2x + y = 10
(5,0)
(0,5)
(7,0)
(0,7)
Answer:
( 5, 0 )Step-by-step explanation:
x - 3y = 5
2x + y = 10 multiply by 3 to eliminate y and solve for x
x - 3y = 5
6x + 3y = 30 then add
7x = 35
simplify:
x = 35 / 7
x = 5
substitute x = 5 back into the eq.2
2x + y = 10
2(5) + y = 10
y = 10 - 10
y = 0
therefore the answer is ( 5, 0 )
