Answer:
[tex]s = \sqrt{2a} [/tex]
Step-by-step explanation:
A = 0.5S^2
2A = S^2
Therefore,
[tex]s = \sqrt{2a} [/tex]
To express the length in terms of the area, is an illustration of change of subject of formula.
The equation that express S in terms of the area is: [tex]S =\sqrt{2A}[/tex]
Given that:
[tex]A = \frac 12S^2[/tex]
First, multiply both sides by 2
[tex]2 \times A = \frac 12S^2 \times 2[/tex]
[tex]2 \times A = S^2[/tex]
[tex]2A = S^2[/tex]
Take positive square roots of both sides
[tex]\sqrt{2A} = \sqrt{S^2[/tex]
[tex]\sqrt{2A} = S[/tex]
Rewrite the equation as:
[tex]S =\sqrt{2A}[/tex]
Hence, the equation that express S in terms of the area is: [tex]S =\sqrt{2A}[/tex]

evaluate the expression for the given value of the variable 9 | 9 -8x | = 2x + 3
Steps to solve:
9|9 - 8x| = 2x + 3
~Divide 9 to both sides
|9 - 8x| = 2/9x + 1/3
~Solve absolute value (part one)
|9 - 8x| = 2/9x + 1/3
-74/9x + 9 = 1/3 (Subtracted 2/9x to both sides)
-74/9x = -26/3 (Subtracted 9 to both sides)
x = 39/37 (Multiplied 37/39 to both sides)
~Solve absolute value (part two)
|9 - 8x| = -(2/9x + 1/3)
|9 - 8x| = -2/9x - 1/3 (Distributed negative sign to left side)
-70/9x + 9 = 11/3 (Added 2/9x to both sides)
-70/9x = -28/3 (Subtracted 9 to both sides)
x = 6/5 (Multiplied 9/-70 to both sides)
Therefore, the solutions are x = 39/37 and x = 6/5

You have $55 in your bank account, and you would like to buy a new phone for $395. You can save $5 for each hour you work. How many hours must you work to buy it?
Answer:
(At least) 68 hours
Step-by-step explanation:
So we already have $55 in our bank account.
And we earn $5 per hour.
In other words, the total amount of money in our account after working x hours is represented by the equation:
[tex]y=5x+55[/tex]
We want to buy a new phone that costs $395. To find out how many hours we need to work, substitute 395 for y. Thus:
[tex]395=5x+55[/tex]
Subtract 55 from both sides:
[tex]340=5x[/tex]
Divide both sides by 5:
[tex]x=68[/tex]
Therefore, we must work for (at least) another 68 hours in order to earn enough money to purchase the phone.
Solve 10-13 find each measurement
Answer:
10)17.5
11)18
12)70
13)110
Problem 10
Answer: RS = 17.5This is because the opposite sides of any parallelogram are congruent (PQ = RS and QR = PS)
======================================
Problem 11
Answer: QT = 18Diagonal QS is cut in half (bisected) by the other diagonal PR. The smaller pieces QT and ST are the same length.
======================================
Problem 12
Answer: angle PQR = 70 degreesThe angle QRS is given to be 110 degrees. Angle PQR adds to this to get 180, so we effectively solve x+110 = 180 to get x = 70. Any pair of adjacent angles of any parallelogram are supplementary.
======================================
Problem 13
Answer: 110 degreesOpposite angles of a parallelogram are congruent. Angle SPQ is opposite of angle QRS = 110.

Carina begins to solve the equation Negative 4 minus two-thirds x equals negative 6 by adding 4 to both sides. Which statements regarding the rest of the solving process could be true? Select three options. After adding 4 to both sides, the equation is Negative two-thirds x equals negative 2. After adding 4 to both sides, the equation is Negative two-thirds x equals negative 10. The equation can be solved for using exactly one more step by multiplying both sides by Negative three-halves. The equation can be solved for x using exactly one more step by dividing both sides by Negative two-thirds. The equation can be solved for x using exactly one more step by multiplying both sides by Negative two-thirds.
Answer:
options 3 and 4 are correct
Step-by-step explanation:
And form the remainder of the problem, you isolate x by just multiplying by the negative reciprocal, which is -3/2, or just dividing by the number in front off x, which is -2/3, which makes statements three and four true. so this makes this three and four options
I hope this helps you :)

Rita bakes pies at The Corner Bakery. The number of pies she can bake, x, is limited by the ingredients
they have in stock. This situation is represented by the compound inequality 2x - 3 < 7 and 5 - x < 8.
Solve the compound inequality and select all the viable solutions.
-2 pies
2 pies
1 pie
O pies
-1 pies
-3 pies
5 pies
6 pies
4 pies
3 pies
Answer:
The solution for the inequality is -3< x <5
The viable solutions are;
-2 pies, -1 pies, 0 pies, 1 pie, 2 pies, 3 pies, and 4 pies
Step-by-step explanation:
The given inequalities are;
2·x - 3 < 7 and 5 - x < 8
Therefore, we have;
2·x - 3 < 7
2·x < 7 + 3
2·x < 10
x < 5
From the other inequality, we have;
5 - x < 8
-x < 8 - 5 = 3
-x < 3
-x/(-1) > 3/(-1)
x > -3
Therefore, the solution for the inequality is given as follows;
-3< x <5
The possible values are;
-2 pies, -1 pies, 0 pies, 1 pie, 2 pies, 3 pies, and 4 pies.

3.5 + 1.2(6.3-7x) =9.38
Answer:
x = 0.2
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
3.5 + 1.2(6.3 - 7x) = 9.38
Step 2: Parenthesis (distribute)
3.5 + 7.56 - 8.4x = 9.38
Step 3: Combine like terms (constants)
11.06 - 8.4x = 9.38
Step 4: Subtract 11.06 on both sides
-8.4x = -1.68
Step 5: Divide both sides by -8.4
x = 0.2

A basketball court is shaped like a rectangle 20 meters long and 10 meter
wide? What is the area of the court?
Answer:
200 squared meters.
Step-by-step explanation:
Since we know the court is a rectangle, we can use the formula for the area of a rectangle:
[tex]A=lw[/tex]
Where l is the length and w is the width.
We are given that the length is 20 meters and the width is 10 meters. Substitute:
[tex]A=20(10)[/tex]
Multiply:
[tex]A=200\text{ meters}^2[/tex]
So, the area of the court is 200 squared meters.

Answer:
A. 31 and B. 26
Step-by-step explanation:
In order for x+6<38 to be true, we need to find the maximum number x can be. So we move 6 to other side which gives us x<32
Of the options A. 31 and B. 26 are the only ones that are less that 32. E. 32 does not count because x must be less than 32, not equal to it.

You found hardwood flooring priced by the square foot. To find the price per square yard, you should do which of the following.
a.) Divide the price per square foot by 9
b.) Multiply the price per square foot by 3
c.) Multiply the price per square foot by 9
d.) Divide the price per square foot by 3
Answer:
D. Divide the price per square foot by 3
Step-by-step explanation:
1 foot = 0.333333 yard
price per square yard of the hardwood = price per square foot / 3
For instance, If the price per square foot is $900, then the price per square yard is
price per square yard of the hardwood = price per square foot / 3
= 900 / 3
= 300
