[tex] {x}^{2} + 4x - 12[/tex]

Step-by-step explanation:

[tex](x + 6)(x - 2)[/tex]

[tex] = > x(x - 2) + 6(x - 2)[/tex]

[tex] = > {x}^{2} - 2x + 6x - 12[/tex]

[tex] = > {x}^{2} + 4x - 12[/tex]

Answer:

x = 8

Step-by-step explanation:

recall that all internal angles of a triangle sum up to 180 deg

we are given that ∠F is a right angle = 90 deg

Simply sum all all the angles and equate the sum to 180 deg

90 + (3x+29) + (5x-3) = 180

90 + 3x+29 + 5x-3 = 180

90 + 3x+29 + 5x-3 = 180

116 + 8x = 180  (subtract 116 from both sides)

8x = 180 - 116

8x = 64  (divide both sides by 8)

x = 64/8

x = 8

Answer:

178.695

Step-by-step explanation:

Answer:

0.0124

Step-by-step explanation:

The negative sign means that we need to move the decimal sign to the left. Since it's -2, the decimal place will be moved to 2 places to the left. From 1.24, it will become 0.0124

Answer:

32.5 miles in 30 minutes.

Step-by-step explanation:

There are a total of 4 - 30 minute segments in a period of two hours. Therefore, in this question, we can simply divide the total distance that Mr Edwards travelled during those two hours by the 4 segments, and that would give us the distance travelled in a single segment of 30-minutes.

130 / 4 = 32.5 miles

Finally, we can see that Mr Edwards travelled 32.5 miles in 30 minutes.

Answer:

3x+30= 116° 2x=64°

Step-by-step explanation:

the angle below 2x is the same as 3x+20 so we know that 5x+20=180 so solve this

5x+20=180

5x=160

x=32

sub x into the angle equations

3(32)+20=116

2(32)=64

Answer:

x=32°

Step-by-step explanation:

3x+20+2x=180°(being co interior angle)

3x+2x+20=180°

5x=180-20

5x=160

x=32°

Step-by-step explanation:

Answer:

5.

Step-by-step explanation:

If you know your multiplication, you would know that 8x5=40. so, 40 divided by 8 equals 5. and if you dont have 8x5 memorized, do 5x10. 50. 10-8=2. 5x2=10. 50-10=40. Voila!

Answer:

Green box contains more sugar.

Step-by-step explanation:

Consider the provided information.

Ashley found 2 boxes of sugar in the kitchen.

The green box says 1.26 kg and the red box says 1.026 kg.

we need to find which box contains more sugar.

To find this we will first check the digit at ones place.

Both the digit has 1 at the ones place. So now check the digit at tenths place.

1.26 has 2 at tenths place while 1.026 has 0 at tenths place.

As we know 2 is greater than 0, thus the number 1.26 is greater than 1.026.

Hence, green box contains more sugar.

Answer: c= 35x + 75

Step-by-step explanation:

If he earns $75 then that will be the constant amount which means it will never change, plus $35 for x cars, will give us the expression 35x + 75 and that has to equal c which is his total earnings.

Answer:

Step-by-step explanation:

Cost of 1 T-shirt = $ 10

Sales tax for 1 T-shirt = 5% * 10 = 0.05 * 10

Cost of n T-shirt = $ 10n

Sales tax for 'n' T-shirts = 0.05 * (10n)

Sales tax on  'n'  T-shirts = Sales tax for 1 T-shirt  * (Cost of n T-shirt)

Answer:

the cost of the t shirt  = 10 times the sale tax which is 5%

Step-by-step explanation:

Answer:

Jimmy purchased 8 of the children's ticket and 7 of the adult's ticket.

Step-by-step explanation:

Let c = children tickets

Let a = adult tickets

Given the following data;

Number of tickets = 15

Total amount spent = $140

Cost of each children ticket = $7

Cost of each adult ticket = $12

*Translating the word problem into an algebraic equation (system)*

For the total number of tickets;

[tex] c + a = 15 [/tex] .........equation 1

For the total amount spent;

[tex] 7c + 12a = 140[/tex] ..........equation 2

*Solving the linear equation by using the substitution method*

Making c the subject in equation 1:

[tex] c = 15 - a[/tex] .......equation 3

Substituting "c" into equation 2;

[tex] 7(15 - a) + 12a = 140 [/tex]

Simplifying the equation, we have;

[tex] 105 - 7a +12a = 140[/tex]

[tex] 105 + 5a = 140[/tex]

Rearranging the equation, we have;

[tex] 5a = 140 - 105[/tex]

[tex] 5a = 35[/tex]

[tex] a = \frac {35}{5} [/tex]

a = 5 (For the $12 adult ticket).

To find the number of children tickets;

Substituting "a" into equation 3;

[tex] c = 15 - 7[/tex]

c = 8 (For the $7 children ticket).

Answer:

1.28

Step-by-step explanation:

slope of line f = (94 - 19)/(-4 - 92) = -75/96

since line g is perpendicular to line f, the product if their slope = -1

therefore, 75/96 x slope of line g = -1

slope if line g = -1/(-75/96) = 96/75 = 1.28

Answer: 6.324555 ?

Step-by-step explanation: The distance formula is the square root of

((-5-(-7))² + (7-1)²)

(-5-(-7))=2, and 2² = 4.

(7-1)=6, and 6²=36.

4+36=40

the square root of 40 is about 6.324555.

Answer:

  a) no

  b) yes

  c) maybe (no)

Step-by-step explanation:

There are two versions of the triangle inequality. One requires ...

  a + b > c

for any triple of side measures a, b, c.

The other allows ...

  a + b ≥ c

which admits "triangles" that have zero height and look like line segments.

Most questions asking "do these lengths form a triangle" are concerned with the "greater than" case, and disallow the "or equal to" case.
