How do you factor: 12x^2-4x-40

Answers

Answer 1

First factor the gcf out
4(3x^2-x-10)

From here use slip and slide for the inner trinomial
x^2-x-30
(x-6)(x+5)
(x-6/3)(x+5/3)
(x-2)(3x+5)

Final answer: 4(3x+5)(x-2)

Number 8. Solve the equation for variable d. Correct answer will get brainliest.

Answers

Answer is choice B) d = (3c-1)/2

The first step is to multiply both sides by 3
c = (2d+1)/3
3c = 3*(2d+1)/3
3c = 2d+1

Then you subtract 1 from both sides to get
3c-1 = 2d+1-1
3c-1 = 2d
2d = 3c-1

Finally divide both sides by 2 to fully isolate d
2d = 3c-1
2d/2 = (3c-1)/2
d = (3c-1)/2
which is what choice B is showing

Total employment for sheet metal workers in 2016 is projected to be 201,000. If this is a 6.3% increase from 2006, approximately what was the total employment in 2006? a. 214,000 b. 188,000 c. 195,000 d. 189,000

Answers

First make the original multiplier:
1+(6.3/100) = 1.063

Then divide the final number by the original multiplier:
201,000 / 1.063 = 189087

Salma drove 605 miles in 11 hours at the same rate how long would it take her to drive 385

Answers

Distance = 605 miles
Time = 11 hours
Velocity = distance/time
Velocity = 605miles/11 hours
Velocity = 55mph

385miles/55miles/hour= 7hours.

Or

605 = 11
385 = x

Solving for x =(385/605)*11
X= 7 hours

divide 605 by 11 to find her speed

605/11 = 55 ( she drove 55 miles per hour )

now divide 385 by 55 to find time

385/55 = 7 hours

What type of math is adding subtracting of positive and negative numbers

Answers

Hello There!

It is Arithmetic.

Hope This Helps You!
Good Luck :)

Final answer:

Adding and subtracting positive and negative numbers falls under the subject of arithmetic in mathematics. The rules for addition and subtraction of integers depend on the signs of the numbers being operated on.

Explanation:

In mathematics, adding and subtracting positive and negative numbers falls under the subject of arithmetic. This concept is also known as integer addition and subtraction.

When you add two positive numbers, the answer is positive. When you add two negative numbers, the answer is negative. When you add numbers with different signs, you subtract the smaller absolute value from the larger one and take the sign of the number with the larger absolute value.

Similarly, when you subtract a positive number from another positive number, or a negative number from another negative number, you follow the same rules. However, when you subtract a negative number from a positive number, you can think of it as adding a positive number, resulting in a larger positive number.

Twice a number is 24 less than 4 times the number find the number

Answers

Let n be a number

2n + 24 = 4n
24 = 4n - 2n
24 = 2n
n = 24/2
n = 12

Final answer:

The question asks for a number which when multiplied by 2 gives a result that is 24 less than the result of the number when multiplied by 4. The solution to this problem is the number 12.

Explanation:

The student's question asks about algebraic expression and solving for a value. This could be written as an equation:

2x = 4x - 24

First, let's simplify this equation by subtracting 2x from both sides, this gives you:

2x = 24

Then, solve the equation by dividing both sides by 2, and we find that the number is:

x = 12

So, the number that the student is searching for is 12. Twice this number is 24, which is indeed 24 less than 4 times the number (48).

A bicyclist traveled with a speed of 12 km/h from a camping ground to a station, located 60 km away. Write a formula expressing the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. Using the formula, find:

Answers

The bicyclist starts at the camp and travels 12 km/h. So in t hours, the bicyclist travels 12t km. The remaining distance (from the bicyclist to the station) is 60 - 12t, the whole distance, 60 km minus the distance the bicyclist has traveled.

[tex]s=60-12t [/tex]

Now you can answer questions such as "how far was the bicyclist from the station after 3 hours?" Substitute 3 for t. s = 60 - 12(3) = 60 - 36 = 24 km.

Answer:

s=18

Step-by-step explanation:

First of all, the formula is s=60-12t. thanks to the person who answered this question first (teehee)

S=distance and t=duration.

We also know that the distance is 60 km, the bicyclists's speed is 12 km/h, and the duration for this example is 3.5 hours.

So, using the formula, we substitute all the variables and s=18.

Answers

The square frame poster has an area of 9 square feet. Therefore each side is 3 feet long. For the poster to lie flat, the cube shaped box must be at least 3 feet long and 3 feet wide. If this were the case, then the cube shaped box would have a volume of 3 x 3 x 3 = 27 cubic feet. Since the volume of the box is more than 27 cubic feet, the box is large enough for the poster to lie flat.

HELPPPPPP PLZZZ

Answers

Take 8 times 7% and then take 8 time 15% add those numbers too $8 and you will find your answer. 7% = 7/100 and 15% = 15/100

Answer:

Total cost $9.76 of Livia's lunch.

Step-by-step explanation:

Livia's bill for lunch came = $8.00

The restaurant included a 7% sales tax = 7% of $8.00

= 0.07 × 8 = 0.56

She left a tip of 15% = 15% of $8 =

= 0.15 × 8 = $1.20

Now add tip and tax to the lunch bill

Bill (Pre tax) = $8.00

Tax 7% = $0.56

Tip 15% = $1.20

= 8.00 + 0.56 + 1.20 = $9.76

Total cost of Livia's lunch was $9.76

Determine the value of y in the equation: -5y-9=-(y-1) (show all work)

Answers

Final answer:

The value of y in the equation is -2.5.

Explanation:

To determine the value of y in the equation -5y-9=-(y-1), we can start by distributing the negative sign to both terms within the parentheses. This gives us -5y-9=-y+1. Next, we can combine like terms by adding y to both sides of the equation. This simplifies the equation to -4y-9=1. To isolate y, we can subtract 9 from both sides of the equation, resulting in -4y=10. Finally, we divide both sides of the equation by -4 to find the value of y, which is -2.5.
