Answers
Answer:
It is not equivalent.
Step-by-step explanation:
You have to expand the brackets :
(x-4)(x+3)
= x(x) + x(3) - 4(x) - 4(3)
= x² + 3x - 4x - 12
= x² - x - 12
Therefore, x² - x - 12 / (x-4)(x+3) is not equivalent to x² - 4x - 12.

Andre and Priyabare tracking the number of steps they walk. Andre records that he can walk 6000 steps in 50 minutes. Priya writes the equation y=118x, where y is the number of steps and x is the number of minutes she walks, to describe her step rate. This week, Andre and Priya each walk for a total of 5 hours. Who walks more step?How many more?
Answers
Answer:
Andre walks 600 more steps than Priyabare
Step-by-step explanation:
Andre is 36,000 minutes while Priyabare walks 35,400. 1st you get the 6000 steps in 50 minutes from Andre and divide the 6000 by 50 to get 120 which you then multiply by 300 (minutes which is 5 hours) and get 36000. Then for Priyabare you multiply 118 by 300 as well (Again because equals 5 hours) and you will get 35,400 meaning Andre walked 600 more steps if you subtract the two.

what is the answer to this? 5(g+4)>15
Answers
Answer:
g > -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(g+4)=15
(5)(g)+(5)(4)=15(Distribute)
5g+20=15
Step 2: Subtract 20 from both sides.
5g+20−20=15−20
5g=−5
Step 3: Divide both sides by 5.
5g/5 = −5/5
G > -1
The solution of the inequality 5(g+4)>15 is g> -1.
Given Inequality:
5(g+4)>15
To solve the inequality, divide the inequality by 5
5(g+4) / 5 >15 / 5
g + 4 > 3
Now, subtract 4 from both side of inequality as
g + 4 - 4 > 3-4
g > -1.
Therefore, the solution is g > -1.

do Q11 do carefully step by step
Answers
Answer:
The measure of the four angles are 30°, 60°, 120°, 150°
Step-by-step explanation:
Q 11.
The sum of the measures of the angle at a point is 360°
Let us use this fact to answer the question
→ Assume that m∠AOB is x°
∵ m∠AOB = x°
∵ m∠BOC is twice m∠AOB
∴ m∠BOC = 2x°
∵ m∠COD is 4 times m∠AOB
∴ m∠COD = 4x°
∵ m∠DOA is 5 times m∠AOB
∴ m∠DOA = 5x°
→ By using the fact above
∵ m∠AOB + m∠BOC + m∠COD + m∠DOA = 360°
∴ x° + 2x° + 4x° + 5x° = 360°
→ Add the like terms
∴ 12x° = 360°
→ Divide both sides by 12
∴ x = 30°
→ Substitute the value of x in each angle to find them
∵ m∠AOB = x°
∴ m∠AOB = 30°
∵ m∠BOC = 2x° = 2(30°)
∴ m∠BOC = 60°
∵ m∠COD = 4x° = 4(30°)
∴ m∠COD = 120°
∵ m∠DOA = 5x° = 5(30)
∴ m∠DOA = 150°
∴ The measure of the four angles are 30°, 60°, 120°, 150°

Answers
Answer: 75°
have: m∠3 = m∠11 = m∠22 = 105°
but m∠22 + m∠21 = 180°

Step-by-step explanation:
As a product development manager, one of your tasks is to determine the best price for an item to increase company profits. To do that, you need to take into account the cost of making the product, the labor of creating the product, and other overhead costs for the company (such as rent, electricity, etc.) If a product uses $14.25 in materials, $3.55 in labor, and $2.15 in overhead costs, what would you need to sell the product for in order to make a 20% profit on the item?
Answers
Answer:
$23.95
Step-by-step explanation:
In order to calculate the best selling price we first need to calculate the total amount of costs. Since we are provided with each individual cost we simply need to add these costs together to find the total.
$14.25 + $3.55 + $2.15 = $19.95
Now that we have the total amount of costs, we know that this is the break-even price that the product needs to sell for in order for the company not to lose money. If the company wants to make a 20% profit on each sale then you would need to increase this amount by 20%. This is done by multiplying the total costs by 1.20, which is 20% divided by 100 to turn it into decimal form, and then adding 1 to make it increase the total cost.
$19.95 * 1.20 = $23.95
Therefore, the company needs to sell each item for $23.95 in order to make a 20% profit.
Two pounds of onions cost $2.30. At this rate, how much will 5 pounds of onions cost?
Answers
Answer:
$5.75
Step-by-step explanation:
Find the unit rate first:
[tex]\frac{2.3 dollars}{2 pounds}[/tex]÷[tex]\frac{2}{2}[/tex]=[tex]\frac{1.15}{1}[/tex]
For every onion, you must pay $1.15. Multiply that by 5 in order to find the cost of 5 pounds of onions. It is $5.75. You can do this with any number to find the cost of any amount of pounds of onions. 4x1.15= 4.60 so the cost of 4 pounds of onions would be $4.60. 6x1.15=6.90 so the cost of 6 pounds of onions would be $6.90. Hope this helps.
