To solve the given system of inequalities, we can solve each inequality separately and then find the intersection of their solution sets. The solution set is x≤5.

To solve the given inequality 3x-8≤23 or -4x+26≥6, we can solve each inequality separately and then find the intersection of their solution sets.

For the first inequality, 3x-8≤23, we add 8 to both sides and then divide by 3 to isolate x: 3x≤31, x≤31/3.

For the second inequality, -4x+26≥6, we subtract 26 from both sides and then divide by -4 to isolate x: -4x≥-20, x≤5.

Since x must satisfy both inequalities, the solution set is x≤5 and x≤31/3. Taking the smaller value, we have x≤5.

Step-by-step explanation:

Arthur got because a pizza is shared by 4 people. however only

2/3 of the pizza is there so it is divided by the four people.

The correct option is b.

The correct problem that can be solved by calculating 4 divided by 2/3 is determining the number of 2/3 cup servings of soup in 4 cups. By understanding how division of fractions work, we can see that there are 6 such servings in 4 cups.

The subject matter of the question is related to basic division and fractions. Specifically, it's asking about when we would need to find the result of 4 divided by 2/3. Given the answer choices, option B is the correct one. The question here is not about sharing a pizza or calculating the quantity of apples for pies, or the amount of sandwich eaten. It's rather about how many 2/3 cup servings fit within 4 cups of soup. When we do the division 4 ÷ 2/3, we're essentially figuring out how many 2/3s there are in 4. This concept can be a bit tricky because dividing by a fraction is equivalent to multiplying by its reciprocal. The reciprocal of 2/3 is 3/2, so 4 × 3/2 = 6. Hence, there are 6 servings of 2/3 cup soup in 4 cups.

Step-by-step explanation:

The length of KD in triangle △AKM, with AK = 6 and KM = 10, and m∠AKM = 93° is 10, since KD is the height of a right triangle and KM is the hypotenuse.

The question asks to find the length of KD in triangle △AKM where KD is perpendicular to AM. Given AK = 6, KM = 10, and m∠AKM = 93º, we can solve for KD using trigonometric ratios.

Since KD ⊥ AM, we have a right triangle △KDM.

We know the hypotenuse KM and angle AKM, so we can use the sine function, where sin(AKM) = opposite/hypotenuse, to find the length of KD. The sine of angle AKM (which is slightly adjusted from 93º to 90º since we are looking for the height in a right triangle) gives us:

sin(90º) = KD/ KM

We know sin(90º) = 1 and KM = 10, so:

1 = KD / 10

Therefore, KD = 10.

Answer:

7x - 8y = 37

Explanation:

y+2 = ⅞(x-3) (distribute ⅞ -- x times 7/8, -3 times 7/8)

y+2 = ⅞x - 21/8 (subtract ⅞x from both sides)

y+2-⅞x = -21/8 (subtract 2 from both sides)

y-⅞x = -37/8 <--- result of -21/8 - 2

Multiply both sides by 8 to get ride of fractions

8y - 7x = -37 (rearrange)

-7x + 8y = -37

It's better to have a positive coefficient for x if you can.  So multiply both sides by -1.  That just means changing the sign of every term on both sides, you get

7x - 8y = 37

Answer:

my 12 inch pito that pito good

Answer:

The distance Shawn went is 40.

Step-by-step explanation:

Given:

N= 5 and M =6

Mountain hike = N = 5

Back down the other side = 2N+1 = 2×5 + 1 = 10 + 1 =11

From Mountain back to truck = 4M = 4×6 = 24

We need to find the total distance he went and can be calculate by adding Mountain hike with back down the other side and then from Mountain back to truck.

Total distance Shawn went = Mountain hike+ Back down the other side + From Mountain back to truck = 5 + 11 + 24 = 40

Hence Shawn went the distance of 40.

Answer:

6.50x + 5 = 21.25 is the answer

Step-by-step explanation:

x=2.5

The inequality that represents Tricia's goal to earn at least $21.25 through her $5 allowance and $6.50 per hour from babysitting is E = 5 + 6.50h ≥ 21.25, where h represents the number of hours she babysits.

The student's question asks for an inequality to represent the situation where Tricia receives a $5 weekly allowance and earns $6.50 for each hour she babysits. The goal is to earn at least $21.25 to buy a present.

Let's denote the number of hours Tricia babysits as h. The inequality representing her total earnings E from both her allowance and babysitting will be:

E = 5 + 6.50h ≥ 21.25

This inequality implies that the sum of Tricia's weekly allowance ($5) and her babysitting earnings ($6.50 per hour multiplied by the number of hours h) should be at least $21.25.

To find the width of the rectangle, use the formula Width = Area ÷ Length. Given an area of 28 square meters and a length of 7 meters, the width is 4 meters.

The area of a rectangle is calculated using the formula:

Area = Length × Width

Given that the area is 28 square meters and the length is 7 meters, we can find the width by rearranging the formula:

Width = Area ÷ Length

Substitute the given values into the formula:

Width = 28 square meters ÷ 7 meters = 4 meters

Therefore, the width of the rectangle is 4 meters.

The weight of a large box is 18.25 kilograms and the weight of a small box is 15.25 kilograms.

Let's use a system of equations to solve this problem. Let's assume the weight of a large box is 'x' and the weight of a small box is 'y'. Based on the given information, we can set up the following equations:

Now, we can solve this system of equations to find 'x' (the weight of a large box) and 'y' (the weight of a small box).

We can start by multiplying equation 1 by 5 and equation 2 by 2 to eliminate 'x':

Subtracting equation 4 from equation 3:

24y = 366

Simplifying:

y = 15.25

Substituting the value of 'y' back into equation 1 or 2, we can solve for 'x':

Therefore, a large box weighs 18.25 kilograms and a small box weighs 15.25 kilograms.

Answer:

5y² + 5y - 11

Step-by-step explanation:

The length of a wooden beam is as a function of y

L(y) = 6y² +  5y + 1

and a piece of length  y²  - 12 is cut off the remaining piece is

6y² +  5y + 1 - y²  - 12  =  5y² + 5y - 11

To find the remaining length of the wooden beam, subtract the length of the cut-off piece from the original polynomial. Simplify the expression to get the final answer: 5y² + 5y + 13 meters. This represents the remaining length of the beam.

Finding the Remaining Length of the Wooden Beam:

We start with the original length of the wooden beam given by the polynomial 6y² + 5y + 1 meters.

We need to subtract the length of the piece that was cut off, which is given by the polynomial y² - 12 meters.

First, write down the original length of the beam:

6y² + 5y + 1

Next, identify the length of the piece cut off:

y² - 12

Subtract the second polynomial from the first:

(6y² + 5y + 1) - (y² - 12)

Simplify the expression by combining like terms:

6y² - y² = 5y²

5y remains unchanged.

1 - (-12) = 1 + 12 = 13

So, the remaining length of the beam is:

5y² + 5y + 13

The remaining length of the wooden beam, expressed as a polynomial in y, is 5y² + 5y + 13 meters.

Answer:

y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2

Step-by-step explanation:

Solve for y:

y^2 + y - 7 = 0

Add 7 to both sides:

y^2 + y = 7

Add 1/4 to both sides:

y^2 + y + 1/4 = 29/4

Write the left hand side as a square:

(y + 1/2)^2 = 29/4

Take the square root of both sides:

y + 1/2 = sqrt(29)/2 or y + 1/2 = -sqrt(29)/2

Subtract 1/2 from both sides:

y = sqrt(29)/2 - 1/2 or y + 1/2 = -sqrt(29)/2

Subtract 1/2 from both sides:

Answer: y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2

Answer:

y=sqrt(29)/2-1/2, -sqrt(29)/2-1/2

Step-by-step explanation:

y^2+y-7=0

completing the square,

(b/2)^2=(1/2)^2=1/4

(y+1/2)^2=7+1/4

(y+1/2)^2=28/4+1/4

(y+1/2)^2=29/4

y+1/2=sqrt(29/4)

y=sqrt(29/4)-1/2

y=sqrt(29)/2-1/2

y=-sqrt(29)/2-1/2

Answer:

on the top is 124 - 115 whille in the bottom is 115

Step-by-step explanation:

To calculate the percent change in the number of employees, use the formula (Change in Quantity / Original Quantity) × 100. The original number of employees is 115, and it increased to 124, resulting in a change of 9. The percent change is approximately 7.83%.

To find the percent change in the number of employees, you can use the following formula:

Percent Change (p) = (Change in Quantity / Original Quantity) × 100

In this case, the Original Quantity is the number of employees at the start of the year (115) and the Change in Quantity is the difference between the number at the end of the year (124) and the number at the start of the year (115).

So, we calculate Change in Quantity as 124 - 115 = 9.

Now, using the formula:

p = (9 / 115) × 100

Calculating this gives us the percentage change:

p = (9 / 115) × 100 ≈ 7.83%

The percent change in the number of employees is approximately 7.83%.
