ST=x+3 and TU=4x-6 what is the value of ST and SU
I know ST=6 and SU=12, but I'm not sure how to do the problem, can someone explain?
(S, T, and U are all on the same line)
Answer:
ST= 6 unit and SU = 12 unit
Step-by-step explanation:
Here, S, T, and U are all on the same line,
Also, T is between S and U,
Such that ST = TU
Here, ST = x+3 and TU = 4x-6,
⇒ x + 3 = 4x - 6
Subtracting 3 on both sides,
⇒ x = 4x - 9
Subtracting 4x on both sides,
⇒ -3x = -9
Divide both sides by -3,
⇒ x = 3
Hence, ST = 3 + 3 = 6,
And, SU = ST + TU = ST + ST = 2 ST = 2(6) = 12
This situation is described by the image below, where we can see that:
Points S, T, and U are colinear points.
Point T is the midpoint of the segment SU.
This means that:
ST = TU
We also know that:
ST = x + 3
TU = 4x - 6
Then we can write:
ST = x + 3 = 4x - 6 = TU
x + 3 = 4x - 6
3 + 6 = 4x - x
9 = 3x
9/3 = x = 3
Now that we know the value of x we can replace it in the equations of ST and TU
ST = x + 3 = 3 + 3 = 6
TU = 4x - 6 = 4×3 - 6 = 6
And T is a point between S and U, this means that:
SU = ST + TU = 6 + 6 = 12
SU = 12

Subtract the following polynomials, then place the answer in the proper location on the grid.
To subtract polynomials, align the terms and subtract their corresponding coefficients.
Explanation:Subtracting polynomials involves subtracting the corresponding terms from each other. Start by aligning the like terms and then subtract their coefficients. If there are any terms that cannot be simplified further, leave them as they are in the final answer. For example, if we have (3x^2 + 2x - 5) - (2x^2 - 3x + 4), we align the terms and subtract them to get (3x^2 - 2x^2) + (2x + 3x) + (-5 - 4) = x^2 + 5x - 9.

Big sale at the mall this weekend! Tank tops are on clearance for 70% off. T-shirts that regularly cost $20.00 are on sale for $12.00 each if you buy 3 or more. All jeans are half off. Write an equation to calculate the total cost of 2 tank tops, 3 T-shirts, and 1 pair of jeans. Use t to represent the original price of a tank top and j to represent the original price of a pair of jeans.
The equation to calculate the total cost of 2 tank tops, 3 T-shirts, and 1 pair of jeans is Total price = 1.6t + 36 + j/2.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Tank tops are on clearance for 70% off.
Let t be the original price.
Sale price of tank top = t - 20% of t = t - 0.2t = 0.8t
Sales price for 2 tank tops = 1.6t
Sale price for a T shirt = 12 if you buy 3 or more T shirts.
Sales price for 3 T shirts = 3 × 12 = 36
Let j be the original price of a jean.
Sale price = j/2
Equation to find the total price is,
Total price = 1.6t + 36 + j/2
Hence the required equation is Total price = 1.6t + 36 + j/2

Final answer:
To calculate the total cost of 2 tank tops, 3 T-shirts, and 1 pair of jeans with given discounts, use the equation C = 0.60t + 36.00 + 0.5j, where t is the original price of a tank top and j is the original price of jeans.
Explanation:
The question involves calculating the total cost of purchasing 2 tank tops, 3 T-shirts, and 1 pair of jeans, with specified discounts, using the original prices of a tank top (t) and a pair of jeans (j) as variables. To compute this, we will establish an equation based on the given discounts.
For tank tops at 70% off, each tank top costs 0.30t since they are 30% of the original price. Buying 2 means spending 2(0.30t) = 0.60t.
For T-shirts, the sale offers them at $12.00 each when buying 3 or more. Thus, the total for 3 T-shirts is 3($12.00) = $36.00.
For jeans at half off, the cost of 1 pair is 0.5j, representing 50% of the original price.
Combining these, the equation for the total cost (C) is: C = 0.60t + 36.00 + 0.5j.

how do I write A quadratic Equation From a Parabola and A Chart
To write a quadratic equation from a parabola and a chart, you can use the vertex form of a quadratic equation which is y = a(x - h)^2 + k. Substitute the coordinates of two points on the parabola into the equation and solve for the unknown variables. Once you have the values, substitute them back into the equation to obtain the final quadratic equation.
Explanation:To write a quadratic equation from a parabola and a chart, you will need to use the vertex form of a quadratic equation which is y = a(x - h)^2 + k. In this form, (h,k) represents the coordinates of the vertex of the parabola.
The equation can be determined from the chart by finding two points on the parabola and substituting their coordinates into the equation.

Jin’s pays 3.48 for a bag of 12 tangerines find the unit price in dollars per tangerine if necessary round your answer to the nearest cent
Answer:
0.29
Step-by-step explanation:
Final answer:
To find the unit price of tangerines Jin bought, divide the total cost of $3.48 by 12. This gives a unit price of $0.29 per tangerine.
Explanation:
To find the unit price of the tangerines that Jin purchased, you need to divide the total cost by the number of tangerines.
Jin paid $3.48 for a bag of 12 tangerines. Therefore, to calculate the price per tangerine, use the following equation:
Unit Price = Total Cost / Number of Units
Unit Price = $3.48 / 12 tangerines
Unit Price = $0.29 per tangerine
If necessary to round to the nearest cent, the unit price remains $0.29 since it is already at the cent level.

Betsy participates in a scavenger hunt that requires her to retrieve items from 4 locations. The locations are on a map with the coordinates as given:
Location 1 is at (−4, −1) .
Location 2 is at (−4, 4) .
Location 3 is at (3, 4) .
Location 4 is at (3, −1) .
The paths from one location to another are straight lines. One unit on the coordinate grid equals 10 yd. Betsy starts at location 1 and goes to location 2, then location 3, and then location 4, and then returns back to location 1.
What is the total distance Betsy has traveled?
Answer:
240 yd
Step-by-step explanation:
Let A, B, C, and D represent location 1, location 2, location 3, and location 4 respectively.
Consider the figure in the attached file.
We need to find the total distance traveled by Betsy.
The distance covered by Betsy is
length of segment AB[tex]+[/tex] length of segment BC[tex]+[/tex] length of segment CD[tex]+[/tex] length of segment DA.
To find the distance AB, we need to find the distance from A to B on y-axis.
So, length of segment AB [tex]=5 [/tex] units
To find the distance BC, we need to find the distance from B to C on x-axis.
So, length of segment BC [tex]=7 [/tex] units
To find the distance CD, we need to find the distance from C to D on y-axis.
So, length of segment CD [tex]=5 [/tex] units
To find the distance DA, we need to find the distance from D to A on x-axis.
So, length of segment DA [tex]=7 [/tex] units
Hence, the total distance covered is [tex]5+7+5+7=24[/tex] units
It is given that 1 unit equals 10 yd, so distance traveled by Besty is [tex]10\times 24=240[/tex] yd

4. The sail of a boat is in the shape of a right triangle. If the area of the sail is 42 square feet and its base is 12 feet, what is the height of the sail?
To find the height of a sail shaped as a right triangle, utilize the area formula A = (base x height) / 2, rearranged to solve for height, leading to the solution of 7 feet for the given area of 42 square feet and base of 12 feet.
To find the height of a sail that is shaped as a right triangle with an area of 42 square feet and a base of 12 feet, we can use the formula for the area of a triangle, which is A = (base x height) / 2. Therefore, we can rearrange the formula to solve for the height:
Height = (2 x Area) / base
By plugging in the values we have:
Height = (2 x 42) / 12 = 84 / 12 = 7 feet
The height of the sail is therefore 7 feet.
