Which angle is a vertical angle with

Answer:

  2b +7

Step-by-step explanation:

We assume you want to simplify this expression. It can be helpful, though is not required, to group like terms near each other.

  = 3b -1b +4 +3

  = b(3 -1) +(4 +3) . . . combine like terms

  = 2b +7

Answer:

a=2

Step-by-step explanation:

You can have "a" on both sides and still get an answer easily. You start off by adding 8a to the right. That makes 8+4a=16. You then subtract 8 from 16 and get 4a=8. Divide by 4 to get your answer. You get a=2

Answer:

a is da answer

Step-by-step explanation:

add the shaded squares and you get 21 but you cant put it over 8 so multiply the denominator by 4, (32), so then it is greater than your numerator. and that's how you get your answer.

Answer:

5.89

Step-by-step explanation:

Answer:

q-0

p-3

Step-by-step explanation:

there are two ways to solve elimination or substitution method I'll use the latter

so take the second equation and find an expression equal to p

p-2q=3

p=2q+3

substitute the above expression in the first equation

(2q+3)1+2q=3

open brackets

2q+3+2q=3

collect like terms

4q+3=3

solve

4q=0

q=0

substitute q in any equation you want I'll choose the second

p-(2×0)=3

p-0=3

p=3

Answer:

p = 3 ; q = 0

Step-by-step explanation:

In this linear pair of eqn. in 2 variables , they have a unique solution i.e. they will have only single solution . We know that

[tex]p + 2q=3[/tex] & also [tex]p -2q=3[/tex] . So, we can also equate them as :-

[tex]p + 2q = p-2q[/tex] (∵ Both the eqn. have 3 in their right hand side product )

Solving the eqn. gives,

[tex]=> 2q + 2q = p-p\\=> 4q=0\\=>q=0[/tex]

Putting the value of q in any one of the linear eqn gives ,

[tex]p+2q=3\\=> p+2(0)=3\\=>p+0=3\\=>p=3[/tex]

Answer:

38.81%

Step-by-step explanation:

Circle area = п r ²

п = 3.14

r = 4 cm

Circle area = 3.14 * (4cm)²

Circle area = 3.14* 16cm²

Circle area = 50.24cm²

Triangle area = (heigth*width)/2

heigth = 2.5 + 4 = 6.5cm

width = 3 + 3 = 6cm

triangle area = (6.5cm*6cm)/2

triangle area = 39cm²/2

triangle area = 19.5cm²

then:

the probability that a randonly select point whitin the circle falls in the shaded area is:

19.5/50.24 = 0.3881     (aprox)

0.3881*100 = 38.81%

Answer:

p = 3

Step-by-step explanation:

9x² - 16 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Thus

9x² - 16

= (3x)² - 4²

= (3x + 4)(3x - 4)

Compare with (px + t)(px - t)

then p = 3

Answer:

-3

Step-by-step explanation:

Please write this as  f(x) = x^2 + 4x - 12.  "x^2" represents "the square of x."

f(2) is the value of this function when x = 2:

f(2) =  f(2) = (2)^2 + 4(2) - 12  =  9 - 12 = -3

Step-by-step explanation:

Additive inverse is when you have a positive number, for example, and it becomes a negative.

Example: 8

The additive inverse of 8 is -8.

So the answer is false.

-64+17 and -64-(-17) is an example of communative property.

The day of the week will be Saturday the next time they are both at the gym.

The least common multiple is defined as the least positive integer that is dividable by both given numbers.

A group's Least Common Multiple (LCM) is the smallest number that is a multiple of all the numbers. For example, the LCM of 4 and 5 is 20; 20 is the smallest number that is both a multiple of 4 and a multiple of 5

To solve this problem, we need to find the least common multiple (LCM) of the two sequences of days, 3 and 4.

The LCM of 3 and 4 is 12, which means that after every 12 days, Max and Ellen will both be at the gym on the same day.

Starting from Monday, the next time Max and Ellen are at the gym together will be 12 days later, which is a Saturday.

Hence, the answer is an option (D) Saturday.

We need to perform a multiplication.

The following rule is applied:

In our example, the factors in the new numerator are:

, ,

Notice that all non-fraction factors are placed in the numerator.

The only factor in the new denominator is: 2.

We need to get rid of all the denominators in this equation.

This can be achieved by multiplying both the left and the right side by the Least Common Denominator.

In our example, the LCD is equal to 2.

[tex](5p^2+3)(p-2)[/tex]

Step-by-step explanation:

In this problem, we need to write the factor form of expression [tex]5p^3-10p^2+3p-6[/tex].

It can be done as follows :

[tex]5p^3-10p^2+3p-6=(5p^3+3p)+(-10p^2-6)[/tex]

Taking common form the terms as follows :

[tex]=p(5p^2+3)-2(5p^2+3)[/tex]

It can be also written as :

[tex]=(5p^2+3)(p-2)[/tex]
